o>r r • THE STATE Department of Environmental 011-1LASKL'1 GOVERNOR SEAN PARNELL RECEIVED FEB 0 7 2014 February 4, 2014 A0GCC Certified Mail, Return Receipt Requested Article No.: 7012 2210 0002 1216 2391 Wayne Svejnoha BLM — Division of Resources 222 W 7th Ave, #13 Anchorage, Alaska 99513 Conservation Division of Spill Prevention and Response Contaminated Sites Program File: 320.38.010 SCANNED 0 2 2014 Re: Potentiall Responsible Party Notice Letter and Information Request NPRA Legacy Wells - General Hazard ID: 26125 Ledger Code: 14339387 Dear Mr. Svejnoha: 610 University Ave. Fairbanks, Alaska 99709-3643 Main: 907.451.2181 Fax: 907.451.5105 This letter is to advise you that the Alaska Department of Environmental Conservation (ADEC) has identified the 136 legacy wells within the National Petroleum Reserve in Alaska (NPRA) as potential contaminated sites. Some of these wells require extensive cleanup of oil and other hazardous substances released to the environment. Since you are identified as a current or past owner and/or operator of these sites, please be advised you may be financially responsible or liable for the investigation and /or cleanup of any hazardous substance contamination that might be present. Alaska Statute 46.03.822 establishes who is liable for contamination. Records available to the ADEC indicate that you meet one or more of the following criteria: » owned or controlled the hazardous substance at the time of its release; » own(ed) or operate(d) the property or facility from which the release occurred; » owned or operated property at which the hazardous substance came to be located; and » arranged for transport, disposal or treatment of hazardous substances that were released. Site History From 1944 through 1982 the US Government drilled 136 wells to explore for oil and gas resources in the NPRA. It is our understanding that other federal agencies and some private companies may have operated or managed these sites in the past. We have also been informed that 23 of these well have been conveyed to public and private entities. The ADEC currently lists 14 of the 136 legacy wells on our database of contaminated sites. The Bureau of Land Management (BLM) is identified as the responsible party for the following sites. Wayne Svejnoha 0 2 February 4, 2014 • BLM Cape Halkett Drill Site (File # 300.38.108) • BLM East Simpson #2 (File # 300.38.109) • BLM East Teshekpuk Drill Site (File # 300.38.110) The U.S. Army Corps of Engineers, under the Formerly Used Defense Sites program, is working with ADEC under the Defense States Memorandum of Agreement on cleanup actions at the 11 Umiat test well sites. BLM is identified as the landowner in our records, and as such is identified as a potentially responsible party in addition to the Department of Defense: C Umiat Test Wells 1-11 (File # 335.38.001) The information contained in these files is part of the public record. Our databases are accessible on the Internet at: http://dec.alaska.gov/spar/csp/db_search.httn Additional Actions Needed ADEC sent a letter on July 11, 2013, identifying an additional 15 legacy well sites with confirmed releases (enclosed). As stated in the letter, ADEC recommends that BLM develop a plan to address known, suspected, and unknown releases at the legacy well sites, in coordination with the appropriate regulatory agencies. We expected a response to this letter before now. Please respond to this letter within 30 days. After we receive and review your response we will determine what additional actions will be taken regarding each site with known or suspected contamination. In addition, with your response, please complete and return the enclosed questionnaire requesting more information about past operators. In accordance with Alaska Statute Title 46, ADEC is authorized to provide regulatory oversight for any contamination response efforts initiated by the responsible party. However, if response actions by the responsible party are not satisfactory to ADEC, we may then assume the lead role in the investigation and cleanup efforts. In the event that State response actions are necessary, the responsible parties may be held financially liable for any response actions taken by the State. Alaska Statutes 46.04.010 and 46.08.070 establish cost recovery procedures for certain costs, including oversight activities, incurred by the State in responding to pollution incidents. If you are determined to be a responsible or liable party, ADEC may bill you at a later date for our expenditures associated with this pollution incident. Expenses for which we may seek reimbursement include: Staff time associated with general or technical assistance; work plan review; project oversight; general project management; legal services; interest; travel; equipment and supplies; and any contracting costs. Pursuant to Alaska Statute 46.08.075, the State may also file liens against all property owned by a person who is responsible or liable for State expenditures. Please respond in writing within thirty (30) days from the date of this letter addressing your intended actions with respect to this pollution incident. If you believe someone else is responsible for this pollution incident (e.g., a past owner or operation of the site) or if you have any questions concerning this matter, please contact Mr. Fred Vreeman at (907) 451-2181. The attached "ADEC Information Request" describes the minimum information expected in your response. Additional information may needed to evaluate the risks and responses required at each legacy well site.

ADEC has also reviewed the response by the Alaska Oil and Gas Conservation Commission (AOGC). We concur with the response by ACIGC and have no further comment regarding the priorities. We do have comments about the investigation and cleanup plans presented in the report. With this letter we arc outlining regulatory requirements related to the environmental work that is proposed and required as part of these cleanups. ADEC is concerned that the 2013 Legacy Wells Strategic Plan prepared by the BLM does not include either assessment of the contingency for assessment of known, likely, or unknown but possible contaminant releases. In addition, BLM plans for surface cleanup of these wells should be made clear in the plan. At least one of these legacy wells has extensive PCB contamination and has resulted in a multi-year cleanup totaling tens of millions of dollars. At others, solid waste disposal practices have resulted in releases to the environment with estimated cleanup costs in the hundreds of millions. Known releases documented in the records we reviewed include crude oil, gasses, refined oil and fuel, drilling fluids that include various organics, metals, and other chemicals, and unknown contaminants from drums and other containers observed to be damaged and abandoned at the various well sites. There are 13 legacy well sites with known releases currently on the DEC contaminated sites list. Many of these are in the process of being addressed, cleaned up, and closed. From our Waited records review there are 15 additional legacy well sites with confirmed releases. These should be prioritized for initial records reviews and then added to the BLM contaminated sites list under our cooperative agreement. Suspected releases include fuel releases from operations, storage, and fuel spills at the sites, impacts to various surface water bodies from spilled fluids during drilling and breaches of containment at reserve and flare pits, continued surface runoff from drilling fluids uncontained at several sites, and down -hole substances that were ejected from the holes over time or during blowouts or drilling operations. 1 Wayne Sve noha ? July 11, 2013 Y The.BLN-1 plan to address these known, suspected, and unknown releases at legacy well sites is notably absent from the documents presented to date. The three primary regulatory agencies that need to be involved in the plan are ADEC — Contaminated Sites, Alaska Oil & Gas Conservation Commission, and ADEC — EH/Solid Waste. Other agencies will need to be consulted. as well. Below we provide recommendations for a coordinated plan using the Uniform Federal Policy for Quality Assurance Project Plans (UFP-QAPP) that will involve all of the regulatory agencies in one coordinated manner. This will allow BLM to address these sites in a consistent and coordinated project which fulfills all of the regulatory requirements so that the sites do not need to be re -visited in the fu=e xvhen they are closed after this project. Attached are our comments on each specific well. The acronyms used on the list include terms that are typically used in a CERCLA type investigation however they are also suitable for investigations conducted under the State of Alaska cleanup rules. These include the following; Historical Records Review (HRR) 'chis is recommended for almost all of the well sites. Much of the information required for these reviews is already contained in various reports and appendices or in BLM files. The Historical Records Review should document the type of releases that might have occurred from drilling operations as well as historical use of the site, and should capture all available information on the drilling fluids used and any product produced or released. Preliminary Assessment (PA) This is recommended for almost all of the well sites. A Preliminary Assessment is a limited scope investigation that provides an assessment of information about a site and its surrounding area to distinguish between sites that pose little or no threat to human health or the environment and sites that require further investigation. The PA is a CERCLA defined document and typically does not require sampling. Site Inspection (SI) If the PA recommends further investigation, then an SI is necessary. The SI is a CERCLA defined document, and it is analogous to an initial report of contamination under state cleanup rules. On some legacy well drillings sites it is evident now that an Sl is required just from a review of the reports. An SI investigation typically includes the collection of samples to determine what contaminants are present at the site and whether they are being released into the environment. An approved site specific workplan is required under both CERCL-A and 18 AAC 75 prior to SI sampling. The SI typically is not intended to develop a full site characterization, but is limited to determining the presence or absence of a release. If contamination is found after completion of the HRR, PA, and SI then a RI/FS under CERCLA, or a Site Characte-rizatiowlteportandcleanup-Alas,under-l-fi-AAC7iis`required. -- ----- - -- — --------- - DEC recommends that BLM incorporate into the strategic pian the processes outlined in this letter. A team of agencies composed of AOGC, DEC -CS, EPA as required, and DEC -EH should address regulatory and technical requirements for these well closures. By cooperating and working together with the regulatory agencies BLM will save time and expense, and regulatory uncertainties will be avoided. The strategic plan should reference a project to prepare a generic workplan. DEC suggests that BLM utilize the generic UFP-QAPP workplan format for the required environmental work. If properly prepared, the workplan could encompass most of the investigations and cleanups required at these sites over multiple years. At other multi -site projects we have found this to be an effective way to reduce uncertainties and risk in these types of investigations. A very small site specific FSP could then be developed as BLM approaches each drilling site. Regulatory decisions made during workplan development would provide more certainty in the planning process for cleanups.

ADEC has also reviewed the response by the Alaska Oil and Gas Conservation Commission (AOGC). We concur with the response by AOGC and have no further comment regarding the priorities. We do have comments about the investigation and cleanup plans presented in the report. With this letter we are outlining regulatory requirements related to the environmental work that is proposed and required as part of these cleanups. ADEC is concerned that the 2013 Legacy Wells Strategic Plan prepared by the BLM does not include either assessment or the contingency for assessment of known,likely, or unknown but possible contaminant releases. In addition,BLM plans for surface cleanup of these wells should be made clear in the plan. At least one of these legacy wells has extensive PCB contamination and has resulted in a multi-year cleanup totaling tens of millions of dollars. At others, solid waste disposal practices have resulted in releases to the environment with estimated cleanup costs in the hundreds of millions. Known releases documented in the records we reviewed include crude oil,gasses,refined oil and fuel, drilling fluids that include various organics,metals, and other chemicals, and unknown contaminants from drums and other containers observed to be damaged and abandoned at the various well sites. There are 13 legacy well sites with known releases currently on the DEC contaminated sites list. Many of these are in the process of being addressed,cleaned up, and closed. From our limited records review there are 15 additional legacy well sites with confirmed releases. These should be prioritized for initial records reviews and then added to the BLM contaminated sites list under our cooperative agreement. Suspected releases include fuel releases from operations, storage, and fuel spills at the sites,impacts to various surface water bodies from spilled fluids during drilling and breaches of containment at reserve and flare pits, continued surface runoff from drilling fluids uncontained at several sites, and down-hole substances that were ejected from the holes over time or during blowouts or drilling operations. Wayne Svejnoha 2 July 11, 2013 The BLM plan to address these known, suspected, and unknown releases at legacy well sites is notably absent from the documents presented to date. The three primary regulatory agencies that need to be involved in the plan are ADEC —Contaminated Sites,Alaska Oil& Gas Conservation Commission, and ADEC —EH/Solid Waste. Other agencies will need to be consulted as well. Below we provide recommendations for a coordinated plan using the Uniform Federal Policy for Quality Assurance Project Plans (UFP-QAPP) that will involve all of the regulatory agencies in one coordinated manner. This will allow BLM to address these sites in a consistent and coordinated project which fulfills all of the regulatory requirements so that the sites do not need to be re-visited in the future when they are closed after this project. Attached are our comments on each specific well. The acronyms used on the list include terms that are typically used in a CERCLA type investigation however they are also suitable for investigations conducted under the State of Alaska cleanup rules. These include the following; Historical Records Review (HRR) This is recommended for almost all of the well sites. Much of the information required for these reviews is already contained in various reports and appendices or in BLM files. The Historical Records Review should document the type of releases that might have occurred from drilling operations as well as historical use of the site, and should capture all available information on the drilling fluids used and any product produced or released. Preliminary Assessment (PA) This is recommended for almost all of the well sites. A Preliminary Assessment is a limited scope investigation that provides an assessment of information about a site and its surrounding area to distinguish between sites that pose little or no threat to human health or the environment and sites that require further investigation. The PA is a CERCLA defined document and typically does not require sampling. Site Inspection (SI) If the PA recommends further investigation, then an SI is necessary. The SI is a CERCLA defined document, and it is analogous to an initial report of contamination under state cleanup rules. On some legacy well drillings sites it is evident now that an SI is required just from a review of the reports. An SI investigation typically includes the collection of samples to determine what contaminants are present at the site and whether they are being released into the environment. An approved site specific workplan is required under both CERCLA and 18 AAC 75 prior to SI sampling. The SI typically is not intended to develop a full site characterization, but is limited to determining the presence or absence of a release. If contamination is found after completion of the HRR,PA, and SI then a RI/FS under CERCLA, or a Site Characterization Report and cleanup plan under 18 AAC 75 is required. DEC recommends that BLM incorporate into the strategic plan the processes outlined in this letter. A team of agencies composed of AOGC, DEC-CS,EPA as required,and DEC-EH should address regulatory and technical requirements for these well closures. By cooperating and working together with the regulatory agencies BLM will save time and expense, and regulatory uncertainties will be avoided. The strategic plan should reference a project to prepare a generic workplan. DEC suggests that BLM utilize the generic UFP-QAPP workplan format for the required environmental work. If properly prepared, the workplan could encompass most of the investigations and cleanups required at these sites over multiple years. At other multi-site projects we have found this to be an effective way to reduce uncertainties and risk in these types of investigations. A very small site specific FSP could then be developed as BLM approaches each drilling site. Regulatory decisions made during workplan development would provide more certainty in the planning process for cleanups.

Foerster DE- Chair, Commissioner C .. �, _ C 1 0 �.l Alaska Oil and Gas Conservation Commission N E 333 W. 7 Avenue, Suite 100 Anchorage, AK 99501 -3539 Subject: NPR -A Temperature Observation Wells DOI/GTN -P Program This letter is in response to your letter dated September 11, 2012, requesting information concerning those wells utilized by the United States Geological Survey (USGS) in their ongoing permafrost temperature monitoring program. The following information is provided in coordination with the USGS project lead Gary Clow for this program. Data for wells: USGS has published reports for the monitoring efforts of these wells. The data collected is part of the Global Terrestrial Network for Permafrost (GTN -P). The DOUGTN -P Deep Borehole Array network is used to monitor the thermal state of permafrost; GTN -P is one component of the Global Terrestrial Observing System (GTOS), which in turn is part of the long -term Global Climate Observing System (GCOS). Please refer to http: / /soa.arcus.org/abstracts /recent- results- us- geological- survey- permafrost- and - climate- monitoring- networl- north -slope -for further information. The USGS is preparing a report documenting the borehole temperature logging results in the National Petroleum Reserve in Alaska during the month of August 2012. Active use as observation wells: According to USGS, the well permafrost temperature monitoring program began in the Iate1970s utilizing 21 wells that had previously been drilled by the U.S. Navy and USGS to identify petroleum resources within the National Petroleum Reserve in Alaska (NPR -A). The U.S. Department of the Interior currently maintains 16 automated active -layer monitoring stations and an array of 17 deep wellbores (Enclosure 1). The approved Sundry Notices submitted by the USGS for performing temperature surveys on the seventeen (17) monitoring wells in the summer of 2012 required Conditions of Approval and can be found in Enclosure 2. Enclosures 3 and 5 provide a list of those monitoring wells during 2012 • and their surveyed date and time. Preliminary results indicate no significant problems were encountered during the temperature logging of these fourteen monitoring wells. Three of the wells (Lisburne Test Well No. 1, Tulageak Test Well No. 1, West Dease Test Well No. 1) were not logged during 2012 due to helicopter availability constraints. The West Dease well has not been logged since 1989. The USGS is retaining the West Dease well in the DOI/GTN -P borehole array as an eventual replacement for the nearby Tulageak well which may be subject to coastal erosion in the future. Mechanical Integrity of Wells: Information previously presented to the Alaska Oil and Gas Conservation Commission (AOGCC)by BLM shows the wellbores have been cemented back into the surface or intermediate casing and were left with diesel column in the upper 2,000 -2,500 feet of the - wellbores to maintain survey capability and minimize restrictions due to freeze plugs. There has been no casing pressure tests performed on these wellbores since the initiation of this borehole temperature survey program in the late 1980s. USGS indicated there has been no wellhead pressure on these wells at the beginning of the temperature surveys and the fluid levels in the surveyed wells have remained stable indicating casing integrity and wellbore continuity (Enclosure 4). If you have additional questions, please contact Wayne Svejnoha, 907- 271- 4407. Sincerely, Bud C.

Any cultural or Paleontological resource discovered by the holder, or any person working on his behalf, situated on lands owned or controlled by the United States shall be promptly reported to the AO. Discoveries must be left in place allowing an examination by BLM cultural or paleontological specialists. C. Prior to any ground - disturbing activity the permittee shall conduct a cultural and paleontological resources survey. P f7 Page 3 0 VI. FIRE A, The BLM, through the AO, reserves the right to impose closjure of any area to operators in periods when fire danger or other dangers to natural resources are severe. B. The authorized user shall be financially responsible for any damage done by a wildfire caused by its operations. Costs associated with wildfires include but are not limited to; Damage to natural resources and costs associated with any suppression action taken on the fire. VII. OPERATIONS A. It is the responsibility of the authorized user to ensure that all individuals brought to the project area under its auspices adhere to these stipulations, Authorized users of the planning area shall provide all employees, contractors, subcontractors, and clients with a briefing regarding stipulations applicable to the lease and/or permit. C. The provisions of this permit do not relieve the Permittee of any responsibilities or obligations required by the laws or regulations of the State of Alaska Department of Fish and Game or the U.S, Fish and Wildlife Service, or other applicable regulations related to this permit D. The authorized user shall protect all survey monuments and be responsible for survey costs if remonumentation is required as a result of the user's actions. E.

F. In the event of obliteration or disturbance of any of the above, the Permittee shall promptly report the incident, in writing, to the Authorized Officer and the respective installing agency, if known. Where General Land Office or Bureau of Land Management right -of -way monuments or references are obliterated during operations, the Permittee shall secure the services of a registered land surveyor or a Bureau Cadastral surveyor to restore the disturbed monuments and references using surveying procedures found', in the Manual of Surveying Instructions for the Survey of Public Lands of the United Stales, latest edition. If the Bureau cadastral surveyors or other Federal surveyors are used to restore the disturbed survey monuments,-the Permittee shall be responsible for survey costs. VIII. STREAMS A, All operations shall be conducted with due regard for good resource management and in such a manner as not to block any stream, or drainage system, or change the character or course of a stream, or cause the pollution or siltation of any stream or lake. Page4of7 1 IX. SUBSISTENCE A The permittee will take no action that interferes with subsistence activities of rural users or restricts the reasonable access of subsistence users to public lands. This may include but is not limited to disturbance of wildlife and their movements near subsistence hunters, and damage to cabins, trails, traditional campsites or caches used by subsistence users. X. VEGETATION A. All activities shall be conducted to avoid or minimize disturbance to vegetation. The clearing of vegetation for camps or aircraft landing areas is prohibited. XI. WASTE A HUMAN WASTES I Toilet paper: Toilet paper must be packed out, or a natural alternative used. Natural options for toilet paper include snow, smooth stones or sticks, leaves and moss. Natural TP options should be disposed of the same as the human waste. Feminine hygiene products and diapers must also be packed out. 2. Urine: Urine can attract animals seeking salt: avoid urinating on plants that can be defoliated by animals attracted to the salt residue. Urinate 200 feet away from camps and trails on rock, bare ground, or water sources. 3. Recommended human excreta disposal in riparian areas: Packing out human excreta is the most eco-friendly means of waste disposal and the toilet can be located wherever is most appropriate. This method helps areas that receive high-levels of use retain their naturalness, and preserves pristine areas. Disadvantages include: it incurs cost and requires logistical considerations. The WAG (Waste Alleviation and Gelling) Bag has become the overall term for any pack- it-out bag system. It generally involves one bag with which holds the excrement and another sturdier, sealable bag. Commercial vendors of waste bag kits, powders and supplies include ReStop, Biffy Bags, and Cleanwaste. 4, Human excreta disposal at camp sites experiencing 60 person-days use or greater in 2012: A designated pit toilet or latrine site should be developed. For a latrine site, dig a long cat hole (e.g. six feet) trench. Start excrement disposal at one end and cover up as deposits are made. Siting must be a minimum of 200 feet away from water, trails, and campsites. The bottom of the trench must be above groundwater. Alternatively, a pit toilet per Alaska Department of Environmental Conservation Water Program Guide Pit Privy Design, Operation and Closure requirements (http://dec.alaska.govtwater/pdf/07CamAnplicationWorksheet.pdp should be constructed, operated and then properly closed at the end of the season. Page 5 of 7 B GARBAGE Attracting wildlife to food and garbage is prohibited. 2, Burial of garbage is prohibited. Burial of human waste is prohibited except as authorized by the .AO. [Special Recreation Permit holders meet all requirements by ,following the guidelines in Leave Nu Trace, Alaska Tundra.] 3 Areas of operation shall be left clean of all debris, C. FUEL 1 Notice of any spill shall be given to the AO as soon as possible or to the BLM Arctic Field Office Hazmat Coordinator, Susan Flora (work/message 907- 474- 2303). Other Federal, State, and NSB entities shall be notified as required by law, 2.

Camp sites shall be located at least 500 meters from any known arctic peregrine falcon nest site, D. The cumulative number of authorized visits (defined as each day in which work is done within 500 meters of a nest site) to any cliff per nesting season (April 15 through August 15) by all authorized users shall be limited to three. G. With the exception of authorized guide hunting trips, hunting and trapping by permittees is prohibited. Page 7 of 7 • , • POLAR BEAR INTERACTION GUIDELINES These Polar Bear Interaction Guidelines (Guidelines) were developed to ensure that activities are conducted in a manner that avoids conflicts between humans and polar bears. Polar bears are protected under the Marine Mammal Protection Act. (MMPA), and were listed as a threatened species under the Endangered Species Act (ESA) in 2008 The MMPA and ESA both prohibit the "take" of polar bears without authorization. Take includes dirsturbance/harassment, as well as physical injury and killing of individuals: In addition to sea ice, polar bears use marine waters and [ands in northern Alaska for resting, feeding, denning, and seasonal movements. They are most likely to be encountered within 25 miles of the coastline, especially along barrier islands during JulY-October. Polar bears may also be encountered farther inland, especially females during the denning period (October-April). Polar bears may react differently to noise and human presence. The general methods for minimizing human-bear conflicts are to: 1) avoid detection and Close encounters; 2) minimize attractants; and 3) recognize and respond appropriately to polar bear behaviors, These Guidelines provide information for avoiding conflicts with polar bears during air, land, or water-based activities. Unusual sightings or questions/concerns can be referred to: Susatme Miller or Craig Perham, Marine Mammals Management Office (MMM Office). 1-800-302-5148; or to Sarah Conn (907) 456-0499 of the Fairbanks Fish & Wildlife Field Office (FFWFO). When operating aircraft: • If a polar bear(s) is encountered, divert flight path to a minimum of 2,000 feet above ground level or 'A mile horizontal distance away from observed bear(s) whenever possible. . When traveling on land or water: • Avoid surprising a bear. Be vigilant—especially on barrier islands, in river drainages, along bluff habitat, near whale or other marine maminal carcasses, or in the vicinity of fresh tracks. • Between October and April special care is needed to avoid disturbance of denning bears. If activities are to take place in that time period the MMM Office should be contacted to determine if any additional mitigation is required. In general. activities are not permitted within one mile of known den sites. • Avoid carrying bear attractants (such as strongly scented 'snacks, fish, meat, or dog food) while away from camp; if you must carry attractants away from camp, store foods in air- tight containers or bags to minimize odor transmission until you return them to "bear- , resistant" containers.* • If a polar bear(s) is encountered, remain calm and avoid making sudden movements Stay downwind if possible to avoid allowing the bear to smell you. Do not approach polar bears. Allow bears to continue what they were doing befOre you encountered them. Slowly leave the vicinity if you see signs that you've bee detected. Be aware that safe t 1 distances will vary with each bear and individual situanon Remember that the closer you are to the animal, the more likely you are to disturb it, • If a bear detects you. observe its behavior and react appropriately Polar bears that stop what they are doing to turn their head or sniff the air in your direction have likely become aware of your presence These animals may exhibit various behaviors: > Curious polar bears typically move slowly, stopping frequently to sniff the air, moving their heads around to catch a scent, or holding their heads high with ears forward, They may also stand up. > 4 threatened or agitated polar bear may huff, snap its jaws together, stare at you (or the object of threat) and lower its head to below shoulder level, pressing its ears back and swaying from side to side. These are signals for you to begin immediate withdrawal by backing away from the hear. If this behavior is ignored, the polar bear may charge. Threatened animals may also retreat. > In rare instances you may encounter a predatory bear. It may sneak or crawl up on an object it considers prey. It may also approach in a straight line at constant speed without exhibiting curious or threatened behavior. This behavior suggests the bear is about to attack. Standing your ground, grouping together, shouting, and waving your hands may halt the bear's approach. • If a polar bear approaches and you are in the bear's path—or between a mother and her cubs—get out of the way (without running). If the animal continues to approach, stand your ground. Gather people together in a group and/or hold a jacket over your head to look bigger. Shout or make noise to discourage the approach. • lfa single polar bear attacks defend yourself by using any deterrents available, I f the attack is by a surprised female defending her cubs, remove yourself as a threat to the cubs. When camping: • Avoid camping or lingering in bear high-use areas such as river drainages, coastal bluffs and barrier islands. • Store food and other attractants in "bear-resistant" containers*. Consider the use of an electric fence as additional protection. Do not allow the bear to receive food as a reward in your camp. A food-rewarded bear is likely to become a problem bear for you or someone else in the future. • Maintain a clean camp. Plan carefully to minimize excess food; fly unnecessary attractants out on a regular basis (i.e. garbage, animal carcasses, excess anti-freeze or petroleum products); locate latrines at least 1/4 mile from, camp; and wash kitchen equipment after every use. • If a polar bear approaches you in camp, defend your space by gathering people into a large group, making noise and waving jackets or tarps. Continue to discourage the bear until it moves off. Have people watch the surrounding area in case it returns later, keeping in mind that polar bears are known to be more ak.tive at night. Additional measures to protect your camp, such as electric fences or motion sensors can he used. Harassment of polar bears is not permissible,, unless such taking'tas defined under the MMPA} is imminently necessary in defense of life and such taking is repo ted to FWS within 48 hours. *Containers must be approved and certified by the Interagency Grizzly Bear Committee as "bear- resistant." Information about certified containers can be found at http://www.igbconline.orgihtinl/container.html, FOR DEPARTMENT OF INTERIOR EMPILOYEES ONLY Use of Deterrents In addition to following the Guidelines above, all U.S. Fish and Wildlife Service (Service) employees must have completed the Department of the Interior'$ (DOI) Bear and Firearm Safety Training course and be current in certification before engaging in field activities. Service staff must practice with and know how to use deterrents prior to cond cting field work. If working in bear habitat, Service staff must anticipate and plan for possible scenarios of encountering polar bears, and identify appropriate responses, prior to initiating field work. Use of non - lethal polar bear deterrents by Service staff is only permissible if it is done in a humane manner and is for the purposes of protection or welfare of the bear or the public. Service staff has the right to use lethal methods to protect the public from polar bears in defense of life Situations, and may do so when all reasonable steps to avoid killing the bear(s) have been taken. Notification of Use of Deterrents The Department of the Interior Bear Incident Report Form will ble used to record and report polar bear -human interactions that require use of deterrents. These incidents will be reported to the MMIvI Office. This information will be used to track interactions over time and improve polar bear conservation and management.

From the perspective of raptor conservation, it is optimal to avoid them entirely. If your activities must entail visiting or approaching these habitats (all of which are encompassed below by the word "clifr" ), follow these guidelines; I. Ground Parties A APPROACH CLIFFS FROM THE MOST VISIBLE AVENUE, beginning at approximately one mile (I 6 kilometers), so that raptors may see and hear your approach at a distance, B. Ifa nest is located; DO NOT VISIT THE NEST SITE, Visiting the nest site can disturb raptors, damage the nest or supporting substrate, guide predators to the nest, or cause young raptors to leave the nest prematurely. C. If raptors occupy cliffs which you must visit, refrain from lengthy stays. Your presence can affect incubation or feeding schedules, and increase egg or y4wng loss due to exposure. Allow your schedule to be flexible, visiting cliffs only on good weather days. IF EXTENDED CLOSE WORK IS NECESSARY, CONDUCT IT AFTER AUGUST I D, Do not camp within 550 yards (500 meters) of possible nesting areas. II. Boating A. Minimize your time spent on river segments near cliffs. III. Aircraft A. When flying from point to point, AVOID LOW FLIGHT ALTITUDES (less than 500' above highest ground level) in the vicinity of cliffs. If weather permits, fly at least 1 500' above highest ground level and away from these areas. 13, If you must approach a cliff. do so along a visible path. This will minimize surprise encounters with nesting birds, NEVER approach from a blind side or from behind. C. If your mission absolutely requires flight close to cliffs and raptors are observed, cut your visit short. Do not make more than two passes in front of cliff areas. D. If you must land in the vicinity of cliffs, do so at a distance of at least one -half mile (800 meters). IV. Summary A screaming adult raptor is adequate proof of your disturbance. Attempts to photograph, climb to nests, or otherwise harass nesting raptors are not in the best interest of these species. In the case of the Golden Eagle, such activities are in violation of The Bald Eagle Act (16 USC 668). Aircraft harassment of any of these species is a violation of The Airborne Hunting Act (16 USC 741 j -1). Remember these key points: A. Avoid cliff areas whenever possible. B. If raptors are located, be cautious in your approach and quick in your work. C. Leave an area immediately if disturbance is apparent. k $ e a t! • f p f.I { S ea ` Sn :ith Bay p • 1 . . ` . , iofkcl! „ f . t 1 .. . .A.,.. ,_ , , , - , y i lyy �• fir l' i s t r ,. ,.- Hurrrison B t ` or m Gmo#MeitinRAres S 11K )YRr,pt7Rt'11)iS7STRK)R1n ANY ( t.

However, if the flyiid level is within a few meters of the surface, the rapid temperature change may not be clearly distinguished in the temperature log.

Abreak-down of the 136 is as follows: • 39 are uncased core holes that did not penetrate oil and gas zone, have .naturally collapsed, and have blended harmlessly into the landscape. • 33 were either transferred to the North Slope Borough through the Barrow Gas Field Act of 1984 or were conveyed to Arctic Slope Regional Corporation. • 20 wells are being used to by the United States Geological Survey (USGS) for climatic temperature and permafrost studies (see Appendix B). • 7 wells are plugged (6 at Umiat, Square Lake #1). • 37 wells that require further evaluation. Following the 2003 field season, members of the legacy well team met to determine criteria for evaluating the risks associated with the above mentioned 37 wells and ranking each well based on these risks. For consistency purposes, the group devised a series of questions to assist in the process: • What is the condition of the existing pad and pits? (e.g. any indication of contamination?) • Is there any solid waste (old equipment, piping, barrels, etc.) or potential hazardous material conditions? • Did the hole penetrate known oil or gas stratigraphy? • Did the well have oil or gas shows, and if so, is the well capable of flowing? • Is the well near human activity, and if so are there conditions present that pose a risk to people? • What is the condition of the wellhead? Have there been any previous problems or repair work? Does the well (in its current condition) pose a risk? • What is the surficial condition of the existing pad and pits? Is contamination a possibility? • Does the presence of unplugged wells have the potential to negatively impact anticipated development? Each of the 37 wells are described in the following pages. Descriptions are ordered in terms of the ranked priority based on the above stated criteria and the concerns identified. Umiat Wells The early Navy wells in Umiat rank at the top of the list. Umiat is located on the north bank of the Colville River 60 miles upstream from the village of Nuiqsut. Natural oil seeps were discovered at Umiat by early explorers. This discovery, along with the detection of seeps at Cape Simpson, motivated the U.S. Navy to conduct a drilling program. Umiat and the Simpson Peninsula were the primary exploration targets in the mid to late 1940s. The Umiat seeps are still visible today. Their locations tend to shift over time. The seeps are currently active in Umiat Lake, just off the northeast portion of the airstrip and in a channel of the Colville River. 22 `~-~ s • • The 11 Umiat wells were drilled from 1945 to 1952. These wells are a concern for BLM due to their close proximity to human activity. Umiat is not a village, but serves as a camp for seismic crews: Umiat is also the primary hub for recreational activities in eastern NPR-A and western CAMA (Central Arctic Management Area). It has one of the few airstrips on the North Slope maintained year-round and is a popular location for purchasing aircraft fuel (Figure 10). The Umiat wells all lie within 2 miles of the camp, with the exception of Umiat #1, which is approximately 5 miles to the northwest. After the U.S. Navy completed drilling operations in 1952, the U.S. Air Force assumed custodial responsibility at Umiat and established the 8,000-acre Umiat Air Force Station. In Tune of aircraft. 1955 the Air Force returned the facility to the U.S. Navy. Since Umiat is a Formerly Used Defense Site (FUDS), the U.S. Army Corp of Engineers (COE) is responsible for the reduction of risk associated with surficial hazardous, toxic, and radioactive waste. The COE has conducted extensive surface investigations in the area and has identified contaminants at several locations. Varying levels of barium, petroleum, pesticides, and polychlorinated biphenyl (PCB) were identified at the wellsites, the landfill, and the nearby slough (U.S. Arnry COE, 2003). Contamination levels were compared to the Alaska Department of Environmental cleanup standards and were used as a screening level. The COE has conducted site remediation at two well locations, Umiat #2 and #5 (Figure 11), and has plans to continue the surface clean up. To facilitate site remediation, the COE plugged wells #2 and #5 in 2002, but plugging the remainder of the wells is the responsibility of the BLM. Four wells were plugged by the BLM in the Winter/Spring of 2004. After the removal of wellheads #2 and #5, the State of Alaska Historic Preservation Office asked the BLM to leave all existing surface objects (wellheads, tanks, pipes) onsite and intact, because of their potential Figure 11: Umiat #2 and #5 prior to removal and historic value. The Alaska Heritage remediation. Photo taken August 2001. Resources Survey (AHRS) included the Umiat wells in an inventory of all reported historic and prehistoric sites within the State of Alaska. This inventory of cultural resources includes objects, structures, buildings, sites, dishicts, and travel routes generally more than 50 years old. Therefore, the wellheads for the other Umiat wells will be left in place after plugging is completed. 23 Umiat #9 Umiat #9 was spudded in June 1951 and completed seven months later in January 1952. The well is cased to a depth of 1,257 feet. The pwpose of the well was to determine the western extent of the producing field. It was also the first hole in which oil-based muds were used in the Umiat area. Umiat #9 is located about half mile to the north-northwest of the Seabee pad. The drill hole penetrated several known oil and gas formations; Ninuluk, Chandler, Grandstand and Topagoruk. Hydrocarbon shows were prevalent within both the Grandstand and the Topagoruk formations. Multiple sands were perforated and tested. Production exceeded 217 barrels per day, thus seemingly showing the benefit of using an oil-based mud. However, the muds did Figure 12: Aerial view of Umiat #9. not allow the different formations to be distinguished. Cement was used in an attempt to "plug back" and isolate individual formations. Samples were taken and sent to a Bureau of Mines lab where the chemical tracer (used during drilling) was measured and the various sandstone samples were examined. This allowed a study of the different lithologies be conducted. The tracer Aroclor used in the well has raised concerns about PCB contamination. However, the well was allowed to flow for seven weeks at 200 barrels per day (Robinson and Bergquist, 1956) prior to shutting it in, possibly purging the potential contaminants. As it stands today, insufficient energy exists in the reservoir for the well to flow to surface and the wellhead has no pressure on it. The well is located within the Northeast planning boundary (see Map 2) on lease AA- 081726. There is some potential for future development to occur in the area within the next 20 years and the well has the potential to leak to surface if development occurs and may adversely affect future development. Surficial wastes around Umiat #9 could present an issue. As was common with early Navy drilling, a gravel pad was not created. Wooden debris exists around the wellhead and there is a pile of drilling muds directly to the north which is void of vegetation (Figure 12). Samples taken by the COE from around the wellhead detected elevated levels of diesel range organics (DRO), residual range organics (RRO) and PCBs (U.S. Army COE, 2003). 24 • The wellhead is equipped with two bull plugs, a flange and a 2 3/-inch nipple. There are no fresh water aquifers in the area, but due to potential contaminants downhole and existing contaminants on the surface, the well does pose a risk to human health and the environment in its current condition. Umiat #6 Umiat #6 was spudded August 1950 to test the southern limits of the Umiat anticline. The hole was drilled to a depth of 825 feet. The well was cased to 35 feet and a 42-foot cement plug was placed on the bottom of the well in order to stop water influx from sands at the base of the permafrost. The well encountered very poor shows in the Killik Tongue (Chandler Formation) and a productive sand in the upper Grandstand Formation. Oil recovered in open-hole pumping tests was produced at rates averaging 53 barrels of oil per day. Insufficient energy exists in the reservoir for the well to flow to surface and there are no fresh water aquifers present. Major caving of the hole occurred and the well was backfilled with mud (Robinson and Bergquist, 1956). The well is located within the Northeast planning boundary (see Map 2) on lease AA- 081726. There is some potential for future development to occur in the area within the next 20 years and the well has the potential to leak to surface if development occurs and may adversely affect future development. The well lies about 500 feet to the northwest of a gravel spur road which connects the Colville River to the eastern edge of the Umiat airstrip. The well is located in wet tundra adjacent to an empty ~5-gallon drum. The well is left open with 8 5/8-inch casing to the surface. It has no gauges, valves or a cover plate. Two thermistor protrude to the surface and rests on the lip of the casing. This well poses no threat to human health or the environment unless development occurs. Umiat #7 Umiat #7 was drilled in 1951 to a depth of 1,384 feet, cased to 1,196 feet ~ and completed as a dry ~ , hole. It was the southern .~" most well drilled on the - ~~----p- Umiat anticline. The objective was to further delineate the southern extent of the producing Figure 13: Umiat #7 summer and winter photos. field. The well encountered residual hydrocarbons in the Chandler and Grandstand formations. Oil recovered in bailing tests was so minute that it was measured in gallons. The small amount of crude recovered in each test is indicative of residual oil staining. The sands encountered in Grandstand are downdip of the productive reservoir and are water bearing. Minor gas shows were encountered at 260 feet (Robinson and Bergquist, 1956). The well is located within the Northeast planning boundary (see Map 2) on lease AA- 081726. There is some potential for future development to occur in the area within the 25 • next 20 years but since the well is located below the oil/water contact it has less potential to be adversely affected or affect future development. The wellhead assembly consists of 7-inch casing (with collar) clamped inside 11 3/-inch casing at a total height of 30 inches (Figure 13). Surrounding the open hole is wet tundra with no indication of remaining debris or other surficial issues. The hole poses no tlveat to humans or the environment. The well location is currently situated on Alaska Dept. of Transportation land that was transferred in 1966, but the well remains the property of the BLM. Additional Umiat Work Umiat has been a site of recent cleanup projects. The cleanup process began in 1994 with the removal of about 1,000 drums, some containing petroleum and transformer oil with PCBs, from the main gravel pad. Another 200 cubic yards of PCB-contaminated soil was removed in 1998 along with 60 cubic yards of lead-contaminated soils. In 2001, 50 cubic yards of PCB soil was excavated with an additional 10 cubic yards removed the following year by the Corps of Engineers (U.S. COE, 2003). J.W. Dalton #1 J.W. Dalton #1 was drilled in 1979 to a depth of 9,367 feet. It is cased down to 8,898 feet and plugged back to 1,530 feet. (Husky Oil NPR Operations for U.S. Geological Survey-J.W. Dalton, 1982). The primary objective of the well was to determine if hydrocarbons were present within the Sadlerochit and Lisburne Groups. Gas shows were encountered in trace amounts in the Ivishak Formation, and the Lisburne and Endicott Group. Poor to good oil shows were discovered in the Ivishak Formation and in the Lisburne Group. A drillstem test of the Lisburne Group recovered 22 barrels of oily water (Gyrc, 1988). This well has been a USGS monitor well since its completion in 1979. Approximately 230 barrels of diesel fuel were placed downhole to act as a neutral medium for collecting wellbore temperatures. In the summer of 2004, warmer temperatures, wind, and wave action eroded 200 feet of the coastline adjacent to the well (Figures 14, 15). This erosion placed the J.W. Dalton # 1 well and reserve pit precariously close 26 Figure 14: Photo of J.W. Dalton taken October 26, 2004. Soil cracking is occurring around the wellhead and the north and east side of the cellar is exposed. Figure 15: J.W. Dalton wellhead with pilings. Photo was taken August 2000. • to the edge of the Arctic Ocean. As a result, casing is now exposed to a depth of 15 feet on the present day beach (Figure 16). The top of the diesel is approximately 60 feet below the present beach level. The reserve pit has been breached on the northwest corner from the advancing shoreline (Figure 17). The pit is known to contain chromium, cobalt, zinc, and barium. However, chromium, cobalt and zinc were detected in background levels, due to the east-west water movement into and out of the pit. Barium is a constituent of the drilling muds and is consolidated with other sediments (U.S. Bureau of Land Management, U.S. Geological Survey, 1992). The well is located within the Northeast planning area (see Map 2), on a tract currently closed to leasing. This well is in danger of becoming engulfed by the ocean. The diesel fuel in the well and reserve pit contaminants raises concerns. The concerns can be eliminated by pumping out the In its cun•ent condition, the well does not pose a threat to humans or the environment, but if the casing were to break in its exposed condition, the diesel fuel would, over time, leak into the ocean. The release of heavy metals from the reserve pit may pose an immediate risk to human health and the environment. The pit was sampled October 26, 2004, and results are pending. 27 r ~gure lb: ~. W.

Simpson Core Test #26 Simpson Core Test #26 was drilled in the middle of one of the larger, active oil seeps in NPR-A (Figure 19). The Navy described this location as Seep 3. The hole reached a total depth of 1,171 feet and was cased to 350 feet. The well encountered one very poor gas show and one productive oil sand in the Ninuluk/Seabee undifferentiated formation. In production tests, the well flowed at rates averaging 110 barrels of oil per day (Robinson and Brewer, 1964). Other formations encountered include the Gubik, Seabee, and Grandstand Formations. Gas bubbles have been observed around the base of the casing since the 2000 field season. Bob Burruss of the USGS, sampled and analyzed gas from Simpson Core #27 which is part of the same oil field, located less than half mile to the east. His findings showed the gas to be biogenic methane indicating that microbial alteration (breakdowns) of the hydrocarbons has generated the gas. Additionally, oil sampled in the well was extremely biodegraded. Simpson Figure 19: The wellhead is located in the center of Core #26 has a wellhead flanged to the the photo. The green color liquid defines the area of active seepage. The orange color is oil-eating casing, a 2-inch line pipe, and four bacteria. wing valves and will likely flow oil if 28 the valves are opened. Access to the wellhead is limited by the depth of oily-water surrounding its base (Figure 20). There are no concerns with contaminating fresh water aquifers if the well is left unplugged, but the well could potentially flow oil and cause damage to surface resources if the well equipment corrodes or, through human intervention, the well is opened or damaged. The well is located within the Northwest planning boundary (see Map 2). The tract was recently leased, receiving a high bid of $7.51 per acre during the NW NPR-A lease sale of 2004. Exploration and development is a distinct possibility within the next 20 years but it is unlikely this well will have an adverse impact on development since any development will likely target deeper, more productive formations. The area around the wellhead looks to have been bulldozed in an attempt to collect the seeping r figure io: ~impsou Core #Z6 drilled in the middle of an oil. The scraped-up earth was oil seep. Depth of the oily-water prohibits access to the then used to build berms around wellhead. the depression. Light amounts of trash appear to have been buried in these berms. The Navy cleaned up the site in the late 70s, removing most of the drums and other debris, but solid wastes, including half barrels and other drums can be found in the wet tar that fills the depression. Simpson Core Test #31 29 psi. The well also penetrated the Gubik and Seabee Formations, which were unproductive (Robinson and Brewer, 1964). The well is located within the Northwest planning boundary (see Map 2). The tract was recently leased and received a high bid of $7.51 per acre during the NW NPR-A lease sale of 2004. Exploration and development is a distinct possibility within the next 20 years but it is unlikely this well will have an adverse impact on development since any development will likely target deeper, more productive formations. A drilling pad does not exist as the well was drilled in an active oil seep, which remains active today (Figure 21). The Simpson Peninsula contains few permanent settlements, but a multitude of summer camps. The well had been a source of fuel for the inhabitants as evidenced by a 10-foot extension pipe hooked up to the wing valve. The extension allowed for the oil to flow down the pipe and collect in a bucket. In 2000, BLM learned that oil was seeping out of a corroded swedge on the wellhead. The potential harm was mitigated by the fact oil was seeping into a natural oil seep. In June 2001, BLM spent $35,000 to remove the old wellhead and install a new master valve and needle valve. Oil and gas samples were taken by the USGS prior to the replacement. There are no fresh water aquifers in the well so there are no risks to sub-surface resources but there are risks to surface resources if the well is left unplugged. Oil will flow to surface if the wellhead or casing corrodes or if the well is left open. There are no solid wastes or hazardous materials (besides the natural oil) that would present a concern or pose a risk to the health and safety of the land and people. Simpson Core Test #30A Simpson Core Test #30A is an oil well drilled in 1951 to a depth of 693 feet and cased to 152 feet. The well encountered some very poor gas shows and one productive sand in the Ninuluk/Seabee undifferentiated formation. The well was bailed and averaged oil rates of 6 barrels per day during bailing tests (Robinson and Brewer, 1964). The well is located within the Northwest planning boundary (see Map 2). The tract was recently leased and received a high bid of $7.51 per acre during the NW NPR-A lease sale of 2004. Exploration and development is a distinct possibility within the next 20 years but it is unlikely this well will have an adverse impact on development since any development will likely target deeper, more productive formations. The wellhead consists of casing swedge, a nipple, and a brass gate valve and will flow oil to surface if the valve is opened. There are no sub-surface fresh water aquifers at risk. However, if the well is left unplugged it could pose a risk to surface resources. In its current state, oil could flow to surface if the well is damaged, corroded, or the valves are opened. Additionally, concerns have been raised regarding the bubbling around the base of the casing. When the valve is opened, the bubbling subsides. This indicates a small leak around the base of the casing or through a hole in the casing. The gas was sampled by the USGS and has been identified as reservoir-produced biogenic gas. While the well does pose a risk, it is mitigated by the fact that the well is drilled in an active, natural oil seep. 30 Simpson Core Test #30 Simpson Core Tests #30 and #30A were drilled about 100 feet apart in the same oil seep. The seep is part of the same regime that contains Cores #26 and #27. These wells were drilled to gain an understanding of the producing field limits and to help determine underlying structure. Simpson Core #30 is an oil well drilled in 1951 to a depth of 1,500 feet. No plugs were set and the well was cased to 102 ft. The hole encountered the same formations as Cores #26 and #27; Gubik, Seabee, undifferentiated Ninuluk/Seabee, and the Grandstand with a few poor gas shows and one productive sand in the Ninuluk/Seabee undifferentiated formation. Poor oil shows were also noted in the deeper Grandstand Formation. During production tests of the shallow oil sand the well was bailed at rates averaging 5 barrels of oil per day (Robinson and Brewer, 1964). The well is located within the Northwest planning boundary (see Map 2). The tract was recently leased and received a high bid of $7.51 per acre during the NW NPR-A lease sale of 2004. Exploration and development is a distinct possibility within the next 20 years but it is unlikely this well will have an adverse impact on development since any development will likely target deeper, more productive formations. The well was left with sheared, open casing above ground. Even though the well produced oil 50 years ago, it is static today. This suggests the hole has collapsed below the shallow casing. There are no fresh water aquifers in the well, however, since the well was drilled to a reservoir with sufficient energy to flow oil to surface, the well should probably be considered a risk if left unplugged. This well would probably be plugged by placing a 100 foot surface plug downhole to eliminate risks to surface resources. The potential risk is alleviated by the fact that the well is drilled in an active, natural oil seep. There is no drill pad as the Navy drilled within the seep and camped on the tundra. Some light trash is present in the seep between the Core #30 and Core #30A, which may prove difficult to clean (Figure 22). The well lies three tenths of a mile from both Core #26 and #27 (Figure 18). Simpson Core Test #27 Simpson Core Test #27 is an oil well that was spudded February 1951 and completed one month later. Total depth of the well is 1,500 feet, with casing down to 102 feet. Oil was encountered at a depth of 380 feet and was bailed at a rate of 3 barrels per day. The core test encountered the same formations as Simpson Core Test #26, with a few very poor gas shows and one productive oil bearing sand in the Ninuluk/Seabee undifferentiated formation. Oil-based muds were used from the drilling depth of 325 to 661 feet. At that point the oil was displaced and the drilling crew resumed using water based muds. 31 N'igure 22: Light trash is present in the seep between Cores #30 and #30A. Additional crude was added downhole at a depth of 1,320 feet. The drill pipe was stuck and the two front derrick legs collapsed below the four-foot extension in an effort to free the pipe. The drilling muds in place were re-circulated dm-ing the repair process. In an attempt to free the pipe, 73 barY•els of crude and 23 barrels of diesel were used to replace the muds and the pipe was worked free. The oil was gradually replaced by mud as the drilling continued, however, some oil remained in the hole after completion. The crude used downhole came from Simpson Core Test #26 (Robinson and Brewer, 1964). There are no fresh water aquifers in the well so there are no risks to sub-surface resources but there are risks to surface resources if the well is left unplugged. Oil could flow to surface if the well equipment corrodes, the well is damaged, or left open. This potential risk is mitigated by the fact that the well is drilled in an inactive, natural oil seep. The well is located within the Northwest planning boundary (see Map 2). The tract was recently leased and received a high bid of $7.51 per acre during the NW NPR-A lease sale of 2004. Exploration and development is a distinct possibility within the next 20 years but it is unlikely this well will have an adverse impact on development since any development will likely target deeper, more productive formations. There is no existing pad. The wellhead consists of 8 5/8-inch casing, a flange and a brass gate valve. The casing was set in a small inactive oil seep. It will flow oil to surface if opened. There is no surface debris present at Core #27 (Figure 23). The well poses little threat to human health and the immediate environment around it in its current condition. Simpson Core Test #29 Simpson Core Test #29 is a dry hole drilled in 1950 to a depth of 700 feet and cased to 152 feet. The purpose of the well was to determine the limits of the producing field encountered at Core #26. A very poor oil show was identified in the Seabee Formation. The productive sand present in the other Simpson Cores does not exist in this well. The test hole also penetrated the Gubik and Grandstand Formations. No oil was recovered from this well (Robinson and Brewer, 1964). The well is grouped higher on the priority list due to its close approximation to Simpson Cores #26, #27, #30 and #30A (Figure 18). The well is located within the Northwest planning boundary (see Map 2). The tract was recently leased and received a high bid of $7.51 per acre during the NW NPR-A lease sale of 2004. Exploration and development is a distinct possibility within the next 20 years but it is unlikely this well will have an adverse impact on development if left unplugged since any development will likely target deeper, more productive formations. The well was left with 8 1/z-inch casing, open to the atmosphere at a height of 6 inches. Thermistor cables protrude from the casing. It is located in a four-by-four foot wooden 32 Figure 23: There is no surface debris present at Simpson Core #27. cellar filled with water. A drilling pad was never established. There is some light trash around the wellhead including drill pipe, and various sized wooden scraps. A small barrel pump and other small debris can be seen in the casing and within the cellar (Figure 24). This well poses no threat to the human population or the environment. Umiat #1 • Umiat #1 was spud in 1945, and completed in 1946. Total depth reached was 6,005 feet and the well was cased to 685 feet. The well encountered residual hydrocarbons and a few poor gas shows in the Seabee, Ninuluk, Chandler, Grandstand, and Topagoruk Formations. The sands of the Grandstand were outside the productive area encountered by other Umiat wells, which are located five miles to the east. Oil recovered in bailing tests was so minute that it was measured in pints and officially recorded as a trace. Lab tests determined the oil to be of a different type of crude oil than that found in the productive Umiat wells (Robinson and Bergquist, 1956). The small amount of crude recovered in each test is indicative of residual oil staining. No fresh water aquifers exist in the Umiat area, so this well poses no tlueat to sub-surface water resources. There is no pressure on the wellhead and it is fitted with a blind plate, a 2-inch nipple and a brass gate valve (Figure 25). The well is located on an unleased tract at the crest of a hill that divides the north and south forks of Seabee Creek. Future development is unlikely because of its location outside the Umiat structure. Left unplugged, the well poses no threat to the environment and has no potential to adversely affect future development. The surficial landscape is dominated by willows with the exception of three piles of drilling muds that are located to the east and north of the wellhead. Vegetation is absent on the slick, clay- type material. The COE tested the piles and found them to be contaminated with barium, Figure 25: Umiat #1 is located about 5 which is not surprising given that barite is a miles from the Umiat airstrip. common drilling fluid component. Through sampling, the COE determined the barium has not migrated down the hill and poses no danger to the Seabee Creek drainage (Ecology and Environment, 1999). There is no 33 r igureL4: Simpson Core #29 i i indication of stressed vegetation down-gradient from the drill muds. Additionally, solid waste in the foi7n of steel framing and scrap metal are near the wellhead. The solid wastes pose no threat but are unsightly. Umiat #11 Umiat #11 was spud June 1952 and completed two months later. The well reached a total depth of 3,303 feet with 486 feet cased. One cement plug was placed at 440 feet. The objective was to test production possibilities of the Grandstand Formation on a fault that parallels the Umiat anticline. The well encountered residual hydrocarbons in the Seabee, Ninuluk, and Grandstand Formations but no oil or gas was recovered during production tests. The sands of the Grandstand were outside the productive area encountered by other Umiat wells, which are over one mile to the south. The well is located within the Northeast planning boundary (see Map 2). The tract is located on lease AA-084141 but there is little possibility of the well interfering with future development due to its location outside the Umiat structure. The well was drilled in the alluvial plain of Bearpaw Creek, 0.6 miles from Umiat #8. A drilling pad was never created as operations consisted of mounting the drill rig on a sled and then placing it on top of large timbers that were secured to pilings (Robinson and Bergquist, 1956). A pile of unvegetated drilling muds is present 30 feet west of the wellhead in between the wellhead and the creek. The wellhead consists of a 10 3/-inch open-ended casing with a collar sticking up inside a 30-inch conductor that is filled with water. Minor wood debris can be found around the wellhead. The well poses no risk if left unplugged. Wolf Creek Area Three test wells were drilled in the Wolf Creek area. The wells were drilled in the early 1950s with the intent of testing the northwest-trending Wolf Creek anticline structure. Wolf Creek # 1 and #3 (Figure 26) are located at the crest of a hill with about 250 feet of relief from the valley. Wolf Creek #2 is located about one and one- third miles north within the Wolf Creek valley. Wolf Creek #2 and #3 are open holes but Wolf Creek #1 is equipped with a wellhead. Wolf Creek #1 Wolf Creek #1 is a gas well drilled in 1951 to 1,500 feet and cased to 48 feet. The well encountered very poor gas shows in the Killik Tongue and productive sands in the Grandstand Formation. The well produced at rates up to 881 MCFPD in open hole tests 34 Figure 26: Wolf Creek #l after adding a new ball valve to the wellhead. August 2004. of the Grandstand. The well is equipped with a blind plate, a 2-inch nipple and a brass gate valve (Figure 26). There is a small gas leak in the threaded wellhead flange and, if the valve is opened, the well will flow about 10 MCFPD but the pressure is so low it does not register on a gauge. In its current condition, the well does not appear to pose a risk to surface or sub- surface resources. The drill pad is shared with Wolf Creek #3. Throughout the pad, there are some wooden pilings, metal anchors and scrap metal. The scraps should not be considered hazardous in this remote region. The leaking gas is of minor concern, however given the weak gas pressure and remote location; the overall risk is very minimal. Wolf Creek #2 Wolf Creek #2 is a dry hole. The well was drilled in 1951 to 1,618 feet and cased to 53 feet. It is located roughly 1 '/ miles north of the other Wolf Creek test wells. The purpose of drilling was to determine if the gas-bearing sandstone beds previously encountered in Wolf Creek #1 would contain any oil. The records indicate a very poor gas show was encountered in the Killik Tongue but no oil or gas was recovered in production tests (Collins and Bergquist, 1959). The hole also penetrated the Seabee, Ninuluk, Chandler, and Grandstand Formations. The well is located on an unleased tract within the Northwest planning area (see Map 2). No offers were received in the June 2004 lease sale for the tract and near-term development is unlikely. The wellhead consists of a plate welded onto the 11 3/-inch casing cut off at ground level (Figure 27). There is no existing drill pad. Solid wastes consist of a few empty 55-gallon drums upstream along the upper floodplain of the creek. The well poses no threat to surface or sub-surface resources and has no potential to adversely affect future development. Wolf Creek #3 Wolf Creek #3 is a gas well. The well was drilled in 1952 to a depth of 3,760 feet and cased to 625 feet. It is deeper than the other two Wolf Creek wells because its primacy purpose was to test the Grandstand Formation (the producing formation around Umiat, 35 miles to the west). The Grandstand Formation produced from four different sands. In 35 rigure a is wort t;reek #Z had casing cut off at ground level. open hole flow tests of the well produced at rates up to 445 MCFPD. The gas appeared to be sufficient to supply a small camp, but not of commercial proportions (Collins and Bergquist, 1959). Two plugs were set in the well above the Grandstand Formation. The top of the shallowest plug is inside the casing at 554 feet. In addition to the Grandstand, the hole penetrated the Ninuluk, Chandler, and Topagoruk Formations. Upon abandonment, the hole was filled with oil-based drilling muds and left open to the environment. A total of 103 barrels of crude were used. The well is located on an unleased tract within the Northwest planning area (see Map 2). No offers were received in the June 2004 lease sale for the tract and near-term development is unlikely. The well poses no threat to surface or sub-surface resources and has no potential to adversely affect future development. The drill pad is shared with Wolf Creek #1. There is some minor debris at the site as noted in the Wolf Creek # 1 description. The wellhead was cut off six inches from the ground surface. This allows seasonal precipitation to accrue in the hole and spill over the sides, but the well poses no threat to surface or sub-surface resources and has no potential to adversely affect future development. Fish Creek #1 Fish Creek #1 was drilled by the Navy in 1949 near an oil seep. Total depth of the well was 7,020 feet. The well was plugged back to approximately 2,550 feet, drilled to a new total depth of 3,018 feet and cased to 3,017 feet. The well was drilled to test a large gravity anomaly that suggested the possible presence of petroleum-bearing rocks and some structural anomaly that might be a trap for oil. Very poor oil shows were identified in the Topagoruk Formation at depths from 5,550 - 6,000 feet and a productive sand was reported at 3,000 feet. The well is not a flowing well but was pump-tested at rates averaging 12 barrels of oil per day tlu•ough agravel-packed. completion. It also produced a small amount of methane gas. The hole encountered the Gubik, Shrader Bluff, Tuluvak, and Seabee Formations. Current condition of the wellhead is that it has no pressure at surface and consists of two wing valves and a master valve. The well is located within the Northeast planning area (see Map 2) on lease AA-081857 where, in 2004, ConocoPhillips Alaska Inc. drilled an exploratory well within seven miles. The target of the exploration is in the Upper Jurassic at depth of approximately 8,000 feet and it is not likely that this unplugged well will adversely affect development in the area. The recent Alpine Satellites EIS approves oil and gas development in this area. ConocoPhillips has proposed roads and a drilling pad less than eight miles from this well and will likely be 36 producing by 2008. Given the low level of risk, the plugging of this well should be postponed until infrastructure is established. Surficially, there are still some solid wastes present. The drilling pad and cellar construction consists of concrete reinforced with steel matting. The concrete, matting, and pilings are still in place today, albeit heaved by permafrost (Figure 28). Several 55- gallon trash drums filled with debris are located off the concrete pad. Other light debris is also present within 500 feet of the pad. The oil seep is located about 1.5 miles to the southwest of the well site and is inactive. The USGS 305-I reports the dimension of the seep as being 6' x 20' (Florence and Brewer, 1964), however, BLM personnel located the seep in 2001 and noted its dimension to be 3' x 6'. Simpson Core Test #28 Simpson Core Test #28 was drilled in September 1950 to a total depth of 2,505 feet and cased to 110 feet. Despite the depth, the hole did not encounter any hydrocarbon shows. The well is located within the Northwest planning area (see Map 2) on a recently leased tract that received a high bid of $21.51 per acre during the lease sale of 2004. Exploration and development is a distinct possibility within the next 20 years but it is unlikely this well will have an adverse impact on development since the well did not penetrate productive zones and future development will likely target deeper, more productive fomations. A drill pad does not exist, however a large area of disturbance is visible. The wellhead consists of open casing inside a wooden cellar. There is considerable solid waste near the well. These include: numerous metal pilings, drill pipe, large wood fragments (spool, plywood, timbers), and some partially crushed drums. The solid wastes are unsightly, but pose no threat to humans or the environment. Simpson Core Test #13 Simpson Core Test #13 was drilled in the summer of 1949. It was a relatively shallow test and did not generate any significant oil or gas shows. The well encountered residual hydrocarbons in the Seabee and Grandstand Formations at depths of 1,079 - 1,084 and 1,138 - 1,148 feet (Robinson and Brewer, 1964). No oil or gas was recovered during production tests. The well is over three miles north of the Simpson Core wells that penetrated productive Grandstand sands. Total depth of the well reached 1,438 feet. The top 26 feet are cased and the hole was filled with water-based drilling mud. Fresh water aquifers were not encountered. The well is located within the Northwest planning area (see Map 2) on a recently leased tract that received a high bid of $21.51 per acre during the lease sale of 2004. Exploration and development is a distinct possibility within the next 20 years but it is unlikely this well will have an adverse impact on development since the well did not penetrate productive zones and future development will likely target deeper, more productive formations. 37 A drilling pad does not exist. Seven-inch casing was cut off at ground level and is very difficult to locate. The well is open to the atmosphere. There is no solid waste, nor is there anything hazardous regarding this location. It should not be considered a risk to surface or sub-surface resources. Simpson Core Test #15 Simpson Core Test #15 was drilled in August 1949 near an active oil seep. The well was drilled to a total depth of 900 feet and cased to 18 feet. The well encountered only residual hydrocarbons in the Ninuluk/Seabee and Grandstand Formations (Robinson and Brewer, 1964). No oil or gas was recovered during well tests. Additionally, fresh water aquifers were not encountered. The well is located within the Northwest planning area (see Map 2) on a recently leased tract that received a high bid of $21.51 per acre during the lease sale of 2004. Exploration and development is a distinct possibility within the next 20 years but it is unlikely this well will have an adverse impact on development since the well did not penetrate productive zones and future development will likely target deeper, more productive formations. There is no existing pad. The well was drilled about '/s of a mile north of a natural seep. The well consists of open ended casing with a height of 18 inches (Figure 29). The area is clean with no solid waste. This well poses no risks to the environment or human activities. Simpson Core Test #14 Simpson Core Test # 14 was drilled in 1949 to a depth of 290 feet. The records do not clearly state how much casing was run but the well was left with casing above ground open to the atmosphere. Its present day location lies within 1000 feet to the west of an active oil seep. The well was not drilled deep enough to encounter the hydrocarbon stained sands evident in the Simpson Core #14A well. The well is located within the Northwest planning area (see Map 2) on a recently leased tract that received a high bid of $21.51 per acre during the lease sale of 2004. Exploration and development in the area is a distinct possibility within the next 20 years. This shallow well did not penetrate any hydrocarbon bearing zones and poses no risk to surface or sub- surface resources, nor does it have the potential to adversely impact future development. 38 • Simpson Core Test #14A Simpson Core #14A was drilled in 1949 to a depth of 1,270 feet and casing was set to a depth of 32 feet. The well encountered only residual hydrocarbons in the Ninuluk/Seabee and Grandstand Formations. No oil or gas was recovered during tests (Robinson and Brewer, 1964) and fresh. water aquifers are not present. Present day location of the well is approximately 1000 feet to the west of an active oil seep. The well is located within the Northwest planning area (see Map 2) on a recently leased tract that received a high bid of $21.51 per acre during the lease sale of 2004. Exploration and development is a distinct possibility within the next 20 years but it is unlikely this well will have an adverse impact on development since the well did not penetrate productive zones and future development will likely target deeper, more productive formations. East Simpson #2 East Simpson #2 was drilled in 1977 to 7,505 feet and cased to 6,427 feet. Five cement plugs were set, with the top of the shallowest plug set at 1,997 feet. The primary objective of the well was to test the Ivishak Sandstone where it onlaps the Pre-Devonian age basement rock (Husky Oil NPR Operations for U.S. Geological Survey, 1982). Small scale faulting was found between the wells in the area, possibly accounting for the thin section representing the Sadlerochit Formation. The well encountered very poor oil shows at 6,000 feet in the Torok Formation and Endicott age sandstones were cored with poor porosity and dead oil shows. 'The well is officially listed as a dry hole. Upon completion of the production tests, the well was plugged back to 1,997 feet and filled with approximately 280 barrels of diesel to facilitate permafrost temperature measurements. However with East Simpson #1 less than five miles away, the USGS has no plans to use this well for temperature monitoring. The well is located within the Northwest planning area (see Map 2) on a recently leased tract that received a high bid of $21.51 per acre during the lease sale of 2004. Exploration and development is a distinct possibility within the next 20 years but it is unlikely this 39 • well will have an adverse impact on development. If this exploration and development establishes infrastructure nearby, it would greatly facilitate plugging this well and significantly reduce costs. The wellhead consists of a casing head, side gate valve, a master gate valve, and a needle valve. The drilling pad is of the thin pad variety and is slowly being reclaimed by natural processes. Exposed pilings stick up a height of two feet from the surface, but no other objects needing removal are present (Figure 31). The cellar is a wooden 12' x 12' with standing water. With the existing plugs and the static condition of the well, there is no risk to surface or sub-surface resources. Kaolak #1 Kaolak #1 lies in the northwest portion of NPR-A and is considered one of the more remote well sites within the reserve. Kaolak #1 was drilled in 1951 to a depth of 6,952 feet and casing was set to 1,000 feet. Drilling served two purposes, to determine the presence of any reservoir characteristics, and to determine if oil or gas shows were present in this remote portion of the reserve. The site was chosen based on a seismograph survey in 1950 that identified an anticline at this location. The intent was to drill to a depth of 8,000 feet, but a windstorm destroyed the derrick. After the storm, the hole was abandoned due to unsatisfactory oil and gas shows. Findings indicated some very poor oil and gas shows in the Chandler Formation and very poor Figure 32: Kaolak #1 with cabin on the drill pad. shows in the Topagoruk Formation. Gas shows were attributed to association with the coal beds (Collins and Bergquist, 1958). Upon abandonment, no plugs were set and the hole was filled with heavy muds. The well is located on an unleased tract, in Southern NPR-A (see Map 2) where a lease sale is scheduled for 2008. Exploration and development in the area is a possibility within 40 Figure 31: East Simpson #2 is partially submerged during the spring thaw. Photo taken June 2003. • the next 20 years, but since this well did not penetrate productive oil and gas zones it will not have an adverse impact. There are no major surface issues. The working area is still visible due to a multitude of wooden pilings around the wellhead and a cabin on the north end of the pad (Figure 32). Off the pad, the area is clean. The wellhead is missing its upper components. All that remains is the top flange above the base plate and the casing spool, leaving 11 3/-inch casing open to the enviromnent. The well is left with a casing head and is open to atmosphere. The wellsite is 45 miles southwest Wainwright, which is the nearest community. There are no hazardous materials or anything that would pose a risk to the general health and safety of the land. The cabin may be a concern, but dealing with the situation is outside the scope of this report. Meade #1 Meade #1 is a gas well drilled to a depth of 5,305 feet in 1950. The well was cased to 2,785 feet and two cement plugs were set, with the top of the shallowest plug tagged at 2,783 feet inside the casing. The well encountered some gas shows in one productive sand within the Grandstand Formation. The gas tested at rates up to 1.1 MMCFPD during openhole flow tests of the sand at 2,949 - 2,969 feet. The well is estimated to have gas reserves of 10 BCF. Gas pockets are relatively common in this portion of NPR-A due in large part to the underlying coal. At one point while conducting tests, some problems were encountered while attempting to pull a testing tool out of the hole; aball-peen hammer was inadvertently dropped downhole, causing the tubing to stick. The tubing could not be freed and as a result, it twisted off leaving tubing in the hole. When the lost tubing could not be pulled out, heavy muds were pumped downhole and the well was abandoned (Collins and Bergquist, 1958). The well is located within the Northwest planning area (see Map 2). The well is adjacent to a recently leased tract that received a high bid of $10.26 per acre during the 2004 lease sale. Exploration and development is a distinct possibility within the next 20 years and has the potential to target the Grandstand Formation. If left unplugged the well has no potential to adversely affect future development. There is no pad present at Meade #1 Several pilings and light trash are present, but at ground level and consists of an open flange bolted to the top of the casing (Figure 33). This differs from the Navy reports that indicate the wellhead was abandoned in place. There is no record as to why it was removed. A BLM field crew bailed the hole and discovered a swedge and 2-inch needle valve junked downhole. This site is very remote (30 miles south of Atqasuk) and since the gas zones are currently isolated below the cement plugs there is a limited risk of adverse impacts to surface or sub-surface resources. 41 Figure 33: Meade #1 wellhead. • Titaluk #1 Titaluk #1 was drilled in 1951 to a depth of 4,020 feet and is a dry hole. The well was drilled on the end of an anticline to test the oil and gas potential of formations within the Nanushuk Group. A few very poor oil and gas shows were encountered in the Grandstand and Topagoruk Formations, but no oil or gas was recovered during multiple production tests. The Ninuluk and Chandler Formations were also encountered, but with no shows. One cement plug was set at 3,471 feet. The placement of this plug is curious since the shows (albeit poor) were reportedly discovered above this level (Robinson and Bergquist, 1959). The well remains in a static condition. Titaluk #1 is located within the Northwest planning area (see Map 2) on an unleased tract. No offers were received in the June 20041ease sale. Near-term development is unlikely. Skull Cliff Core Test #1 Skull Cliff Core Test #1 was drilled in 1947 to a depth of 779 feet and is a dry hole. No shows of oil or gas were reported while drilling through the Gubik, Grandstand, and Topagoruk Formations. While drilling to the target depth of 1,500 feet, the drillstring was lost in the hole and fishing attempts were unsuccessful in recovering the lost drillstring. The drilling mud was bailed down to the top of the fish and the remainder of the well was filled with diesel to 54 feet to prevent the wellbore from freezing and facilitate downhole temperature measurements. It is plausible that the casing could corrode and the diesel fuel could seep into the sub-surface strata, but since there are no fresh water zones in the well it is not considered a risk that would adversely impact sub-surface resources (Collins and Brewer, 1961). The well is located within the Northeast planning area (see Map 2). The well lies adjacent to a recently leased tract that received a high bid of $10.77 per acre during the 20041ease sale. Exploration and development is a distinct possibility within the next 20 years but it 42 • is unlikely this well will have an adverse impact on development since industry will likely target deeper, productive formations. An oil seep located at the base of Skull Cliff (land/ocean contact) was observed and documented in the 1940s, which influenced the Navy's decision to drill. BLM and USGS crews searched for the seep when they were in the area but nothing was found at the cliff/beach contact. However, another seep was reported in 1996 by a group from the Academy of Natural Sciences in a small gully about a mile to the east near the old radio tower site. This seep was never confirmed by BLM. Surficially, a drill pad was never established, but a large area of activity is defined by roughly 200 drums, metal tracks, wood debris and various other scraps that litter the site (Figure 35). Presently, the well consists of open casing with a wooden plug shoved into it. There does not appear to be any stressed vegetation that might indicate a hazardous situation. Since the well did not encounter o11 and gas l+'igure 35: Solid waste primarily in the form of empty formations and has no pressure at drums litter the area around Skull Cliff Core Test. The the surface, it is not considered a Wellhead is in the upper left portion of the photo. risk to surface resources. The only potential risk is that this site lies near a popular winter route between Barrow and Wainwright and it is possible for a snowmachine to impact the solid waste. Barrow is approximately 30 miles to the northeast and Wainwright is about 60 miles to the west. Oumalik #1 Oumalik #1 was drilled in 1950 and is a dry hole. The well was drilled to a total depth of 11,872 feet and cased to 2,762 feet. It is the deepest well drilled by the early U.S. Navy program. The well location was positioned on the apex of the Oumalik Anticline and drilled with the intent of revealing the oil, gas, and water content of the penetrated stratigraphy. Two cement plugs were set, the shallowest of which is inside the casing at 2,543 feet. Very poor oil and gas shows were reported in the Grandstand Formation, and poor gas shows were noted in both the Topagoiuk and Oumalik Formations. Small undetermined volumes of gas were recovered during multiple production tests. It is believed that the gas encountered was large enough to furnish fuel to a camp but not large enough to become a commercial producer. The gas encountered during drilling showed high gas pressure, but the sandstones in which they were observed are thin with low porosity (Robinson and Bergquist, 1956). The gas zones are currently isolated by the cement plugs and pose no risk to sub-surface resources. The wellhead and a fabricated plate are below ground level. Two 2 '/z-inch nipples open to the atmosphere are above ground to allow thennistor cables to be run into the well. The well is located within the Northwest planning area (see Map 2) on unleased pact that received no bids during the lease sale of 2004. Near-term development is unlikely. If left 43 I~ ~J unplugged, the well has no potential to adversely affect future development. The existing pad contains piping from a ground refrigeration system similar to Topagoruk #1. The ground in this area is somewhat swampy with high susceptibility to permafrost melt. Circulating cooled diesel fuel in the pipes enabled drilling to occur without thawing the ground. The steel pilings were pulled from the ground to be reused at another site (Robinson and Bergquist, 1956}. However, steel pipe filled with diesel fuel remains. A 6- inch circumference of sh•essed vegetation was noted around several of the low-cut pipes. Despite the diesel, the well does not pose a risk to any existing communities or habitation. It is in a remote location approximately 55 miles southeast of Atqasuk. Overall, the well poses no risk to people or the environment. East Oumalik #1 East Oumalik #1 was drilled on a ridge that overlooks an unnamed tributary of the Oumalik River. Topographic relief is approximately 100 feet. The drill site is highly remote as the nearest village (Atgasuk) is 65 miles away. The well was drilled in 1951 and reached a total depth of 6,035 feet and is cased to 1,100 feet. It is a diy hole. Very poor oil and gas shows were reported in the Grandstand Formation and very poor gas shows were reported in Topagoruk Formation. The well is located within the Northwest planning area (see Map 2) on an unleased tract that received no bids during the lease sale of 2004. It is unlikely that exploration and development will occur in the vicinity of this well in the near future. If left unplugged, the well has no potential to adversely affect future development. The well was left with open casing below ground level and has thermistor cables protruding from inside the casing. The casing is marked by a 7-foot, %-inch pipe. The open pipe lies within awater-filled cellar. The standing water has produced numerous algae and other aquatic vegetation obscuring the wellbore. Surficial hazards consist of several 10-foot timbers and a few 4-foot pipes (probably rig anchors) sticking up out of the ground. The site is mostly overgrown with shrubs and appears to be relatively clean. The airstrip, incoming, and outgoing trail scars are obvious and can be used to navigate to the wellsite. There are no risks associated with the well in its current condition and was given this ranking due to its close proximity to Oumalik #1. Topagoruk #1 Topagoruk #1 was drilled in 1951 to a depth of 7,154 feet and is a diy hole. The intent was to test a small, buried anticline and the various formations associated with it. The well was cased to 6,073 feet, plugged back to 6,175 feet and then drilled to a new total depth of 10,503 feet. Prior to re-drilling to total depth, approximately 250 barrels of crude oil from Cape Simpson were added downhole to help offset lost circulation and caving. Additionally, 20 barrels of diesel were added downhole during the drilling phase. No plugs exist in this well. The well is left with open casing to the surface and thermistor cables protruding from the casing (Figure 36}. The well encountered the following stratigraphic units while drilling; Gubik, Grandstand, Topagoruk, and Oumalik Formations, Middle and Upper Jurassic rocks, Shublik Formation (Triassic age), Permian rocks, and Lower-Middle Devonian rocks. Hydrocarbon shows were limited to a few very poor gas shows in the Oumalik Formation. No oil or gas was recovered during 44 multiple production tests (Collins and Bergquist, 1958). The well penetrated no fresh water aquifers and does not represent a threat to surface or sub- surface resources. The well is located withiri the Northwest planning area (see Map 2). It is adjacent to a recently leased pact, receiving a high bid of $50.00 per acre during the NW NPR-A lease sale of 2004. Exploration and development in the area is a distinct possibility within the next 20 years but since this well did not penetrate productive oil and gas zones it will not have an adverse impact. • There is not a visible pad, but rather an area of disturbance. Disturbance stretches 1/4 mile in an Figure 36: Topagoruk #1 casing on its east-west direction and /g of a mile in a north- side. When the casing was pulled out of south direction. Solid wastes exist in the form of the ground, thermistor cables were piping remaining from a refrigeration system that discovered. circulated. diesel to keep the permafrost frozen. A potential hazard exists because diesel still occupies the ground circulation lines. These lines stretch approximately 750 feet to the east, 250 feet to the north, and 100 feet to the south from the wellhead. Other debris on site include some large, partially-burned timbers, awater-filled wooden box (Figure 37) that resembles a cellar ('/4 mile east of the wellhead), and drilling muds. Atgasuk is the closest village approximately 30 miles to the southwest. The well is remote with the exception of a subsistence camp approximately one mile southwest of the wellhead along the Topagoruk River. East Topagoruk #1 Topagoruk's wellhead consists of an open hole cut off at the ground surface ,with several thermistor cables. A thin piece of weathered metal fits around the cut-off casing to resemble a marker. The weathered metal has been smashed at the base and now lies bent in half on its side. Overall this site poses little hazard to the environment or human population. East Topagoruk #1 was drilled on top of a small ridge in the Chipp River delta in 1951. It reached a total depth of 3,589 feet and is cased to 1,100 feet. The purpose of the well was to test an anticline with closure as well as test the fluid content of the permeable Cretaceous sandstone (Collins and Bergquist, 1958). A very poor gas show in the Topagoruk Formation is the only reported hydrocarbons encountered in the well and no oil or gas was recovered during multiple production tests. One cement plug was set in the 45 Figure 37: Drilling muds and a wooden box that resembles a cellar are located about''/o mile east of the wellhead. well at 1,049 feet. The well is located within the Northwest planning area (see Map 2) on a recently leased tract. The tract receiving a high bid of $84.99 per acre during the NW NPR-A lease sale of 2004. Exploration and development in the vicinity of this well is a distinct possibility within the next 20 years but it is unlikely this well will have an adverse impact on development since the well did not penetrate productive zones and future development will likely target deeper formations. A drill pad does not exist. There are a few rig anchors near the wellhead, but no other surficial debris. The current state of the wellhead is open-ended 10'/-inch casing. Casing height is three feet above the ground surface. It is housed in a small 9' x 9' water-filled cellar. The area is remote and poses no health and safety risks to humans or the environment. Knifeblade Wells There were three shallow test wells drilled in the Knifeblade Ridge area. Knifeblade #1 was drilled on the ridge at the head of a small stream, with wells 2 and 2A drilled about a mile downstream. The wells are in a highly remote location with Umiat being the nearest settlement, 65 miles to the east. Knifeblade #1 Knifeblade #1 is a dry hole drilled in 1951. The well was drilled to a depth of 1,805 feet and cased to 1,211 feet. The purpose of the well was to test the oil and gas properties of the Grandstand and Tuktu Formations (Robinson and Bergquist, 1959). The well encountered very poor gas shows in the Killik Tongue of the Chandler Formation and very poor oil and gas shows in the Grandstand Formation. The well is located on an unleased tract, in Southern NPR-A (see Map 2) where a lease sale is scheduled for 2008. It is unlikely that exploration and development will occur in the vicinity of this well in the near future. If left unplugged, the well has no potential to adversely affect future development. Surficially, there are no concerns associated with this well. A drill pad does not exist and the wellhead consists of open-ended casing (Figure 38). The wellhead is 8 5/8- inch pinup inside 11 by 12 '/-inch collar. The plumb-bob hit solid at 12 feet. Total height for the well is about three feet. If this well is left in its current condition, it poses no risk to adversely impacting the surface or sub-surface resources. 46 Figure 38: Knifeblade #1 is located in a marshy area at the headwaters of a small creek. Knifeblade #2 Knifeblade #2 is another dry hole drilled in 1951. It was the first of the three Knifeblade wells drilled and reached a total depth of 373 feet, cased to 45 feet, before being junked and abandoned. The purpose of the well was to test the oil and gas properties of the Grandstand and Tuktu Formations (Robinson and Bergquist, 1959). The well did not encounter any hydrocarbon shows. The well is located on an unleased tract, in Southern NPR-A (see Map 2) where a lease sale is scheduled for 2008. It is unlikely that exploration and development will occur in the vicinity of this well in the near future. If left unplugged, the well has no potential to adversely affect future development. Surficial issues are negligible. A drill pad does not exist and the wellhead consists of open-ended casing. There are approximately eight empty drums near Knifeblade #2 and #2A. The wells are highly remote and should not be considered a threat to the environment or human activity. Knifeblade #2A Knifeblade #2A, also drilled in 1951, reached a total depth of 1,805 feet and was cased to 38 feet. The well lies 28 feet to the north of Knifeblade #2A. The purpose of the well was to test the oil and gas properties of the Grandstand and Tuktu Formations (Robinson and Bergquist, 1959). Only very poor oil and gas shows were reported in the Grandstand Formation. The well was left with casing open to the atmosphere and poses no threat to surface or sub-surface resources in its current condition. The well is located on an unleased tract, in Southern NPR-A (see Map 2) where a lease sale is scheduled for 2008. It is unlikely that exploration and development will occur in the vicinity of this well in the near future. If left unplugged, the well has no potential to adversely affect future development. Simpson #1 Simpson #1 test well was drilled with a rotary rig in 1948 by the U.S. Navy. The well was drilled to a total depth of 7,002 feet and cased to 5,954 feet. The purpose of the well was to test the various formations of the Lower Cretaceous and Upper Jurassic rocks. The well encountered several very poor oil and gas shows and one productive gas sand in the Lower Jurassic at a depth of 6,183 - 6,193 feet. The well produced gas at rates up to 3.0 MMCFPD during open hole flow tests of this Lower Jurassic sand. The gas zones are currently isolated from other formations and the surface by two cement plugs set above the productive sand. The top of the shallowest plug is at 5,520 feet (Robinson and Yuster, 1959). The well is located within the Northwest planning area (see Map 2) adjacent to recently leased tract that received a high bid of $7.51 per acre during the lease sale of 2004. Exploration and development in the vicinity of this well is a distinct possibility within the next 20 years and this exploration has the potential to target the Lower Jurassic. Since the well is partially plugged, however, it poses little risk to surface or sub-surface resources and will not likely adversely affect any future development. 47 • The pad is highly visible and was constructed in the same fashion as Fish Creek #1 in which concrete was used as a working pad. Concrete was poured over a landing mat which was placed on pilings. As a result of ground movement from perniafrost freeze/thaw cycles, the concrete has buckled in numerous places creating apartially- collapsed surface. This feature provides excellent shelter to small animals and rodents. Additionally, there is a small pile of drilling muds near the wellhead. The well was left equipped with a casing flange, spool w/ side bull plug, and another flange and nipple and is shut-in with no pressure at surface. The components past the flange have since been removed. Overall, the current condition of the site is non-threatening to the sparse human population and the surrounding environment. North Simpson #1 North Simpson #1 was drilled in 1950 to a depth of 3,774 feet and cased to 109 feet. No hydrocarbon shows were reported during the drilling of this well as no sandstone was encountered (Robinson and Yuster, 1959). Upon completion, no plugs were set and the hole was filled back with muds. The well is located within the Northwest planning area (see Map 2) adjacent to a recently leased tract that received a high bid of $12.76 per acre during the NW NPR-A lease sale of 2004. Exploration and development in the vicinity of this well is a distinct possibility within the next 20 years but it is unlikely this well will have an adverse impact on development since the well did not penetrate productive zones and future development will likely target deeper formations. South Simpson #1 South Simpson #1 was drilled in 1977. The purpose of the hole was to test the Sadlerochit Formation where it laps onto the south flank of the Banow Arch. The well was drilled to 8,795 feet and cased to 7,206 feet. Reports show that poor gas shows were identified in the Nanushuk Group, Kingak Shale and Shublik Formation. Gas flowed at a rate of 75 MCFPD between 6,522 - 6,568 feet within the Kingak Shale (Gyrc, 1988). The gas contained more than 70% nitrogen. The origin of the high nitrogen content is unknown, but appears to be a localized phenomenon (Bunuss, 2003). Sandstone tongues 48 • (Simpson sand) within the Kingak Shale in the Simpson and Barrow localities are known to display good gas reservoir quality (Houseknecht 2001). Poor oil shows were discovered in the Nanushuk Group and Shublik and Torok Formations. Drill stem tests did not recover any oil. The well is located within the Northwest planning area (see Map 2) on a recently leased tract that received a high bid of $5.01 per acre during the lease sale of 2004. Exploration and development is a distinct possibility in the near future since the well is properly plugged it will have no adverse impacts on development. Surficially, the pad and pits are in good shape. The cellar has been backfilled r ~gure 4v: youth Simpson #1 had its cellar backfilled with silt, with silt which resulted in consequently burying the casing head. the burial of the Casing head (Figure 40). Above the surface, the wellhead consists of a 4-inch line pipe and a master valve. The master valve is frozen in the open position. The needle valve previously located above the master valve no longer exists. Beneath the casing head the well is plugged to surface and has no potential to adversely effect surface or sub-surface resources. The wellhead stands about eight feet high. Aplumb-bob was dropped and hit solid at 8 feet and stuck. It was subsequently lost. An old, stripped snowmachine sitting next to the wellhead is the only sizable object that would be considered solid waste. Overall, there is no risk associated with this well. Inigok #1 Inigok #1 was drilled in 1979 to a depth of 20,102 feet and cased to 17,432 feet. The well objective was to test astructural/stratigraphic trap within the Sadlerochit and Lisburne Groups (Husky Oil NPR Operations for U.S. Geological Survey-Inigok, 1983). Some very poor gas shows were recorded in the Sag River, Nanushuk, and Endicott Group. Poor oil shows were reported for the Kingak Shale and Lisburne Group. The best shows were found in the base of the Torok Formation at 8,852 feet. No oil or gas was recovered during multiple production tests. The wellhead consists of three spools, each with a gate valve, a master valve, and a needle valve. Ten cement plugs were set in the well and it is plugged to surface. The well is located within the Northeast planning area (see Map 2) on a recently leased tract that received a high bid of $20.34 per acre during the lease sale of 2002. Total E&P Incorporated drilled an exploratory well 15 miles north of Inigok #1 and used the gravel 49 pad and airstrip near the well for staging areas and a camp. It would be fairly simple to remove the wellhead but the well has no potential to adversely affect surface or sub-surface resources. Additionally, the well poses no threat to adversely affect future development. Inigok # 1 is one of the few logistical Centers Figure 41: Aerial view of Inigok #1. The drill pad and reserve pit within NPR-A (Figure are visible in the top of photograph. A road leads from the apron of 41). The airstrip and pad the airstrip to the drilling pad. are maintained with no solid wastes present. The wellhead poses no risk, and with the plugs already in place, could be removed. Additionally, this well has ayear-round airstrip and serves as a logistical base to various NPR-A activities. USGS Monitored Wells The USGS has used wells drilled in the NPR-A for collecting temperature data to better understand both the global temperature pattern and its effects on the permafrost. The wells that are currently used are properly plugged above the hydrocarbon bearing zones and into the well casing. The wells are filled with diesel fuel down to the shallowest plug at depths ranging from 1,500 - 3,000 feet. For a list of wells see Appendix B. The program began in 1958 and will continue for the foreseeable future. After this project ends, the wells will have the diesel extracted and the well will be properly plugged to surface. Diesel is a non-con-osive agent, and even if the casing should corrode there would be no impact to the surface resources and minimal impact on the sub-surface resources as there are no known fresh water aquifers in NPR-A. The following wells are monitor wells with surficial issues. It is difficult to establish a rank since the wells are sufficiently plugged. The cleanup priority is difficult to determine as the primary tlueat lies with wells having downhole issues. However, political concerns could influence the timing in which the surface issues are dealt. East Teshekpuk #1 East Teshekpuk # 1 was spudded in March 1976. The well was drilled to a depth of 10,664 feet. It is an active USGS monitor well that was properly plugged. The top of the shallowest plug is located at 2,400 feet. From that point to the surface, the hole is filled with diesel fuel. With the well properly plugged and diesel fuel being anon-corrosive agent, there is no downhole issue with the well at this time but there are solid wastes buried on site that may warrant removal. 50 • East Teshekpuk #1 was drilled on a small peninsula on the southeast side of Teshekpuk Lake. The southern shore of the peninsula is protected from the prevailing northerly winds, however the north shore doesn't have the luxury of a barrier and is subject to erosion. Unfortunately, solid wastes from the camp and drilling operation were buried on the northern portion of the pad, possibly in the old reserve pit. The northern shore has been battered by numerous storms which have eroded the shoreline and exposed the solid wastes. The wastes are unsightly and potentially hazardous. While the nearest village of Nuigsut is 52 miles to the southeast, Teshekpuk Lake is rich in subsistence resources and numerous summer cabins dot the lake's shoreline. It is possible that at the time of surficial restoration, the downhole could be pumped free of diesel and plugged to the surface. Awuna #1 Awuna #1 was spudded February 1980 and completed April 1981. It is the only well drilled in the southwest portion of NPR-A and is 90 miles south-southwest of Atgasuk. Awuna is the most remote well in the entire petroleum reserve. The well was drilled to a total depth of 11,200 feet. Drilling was conducted over two consecutive winters. Ice roads and an ice airstrip were constructed for logistical support. The project cost approximately $6 million (Husky Oil NPR Operations-Awuna, pg 5). Due to the orientation of the pad, the prevailing winds force wave action into the drilling pad, undermining the sands and silts which make up the pad. Below the sands and silts, Styrofoam was used to insulate the underlying permafrost. Wave action has eroded tens of feet into the drilling pad, exposing the Styrofoam, which consequently breaks loose and blows away. Wooden pilings exposed from erosion show how much ath•ition has taken place. Styrofoam can be seen all around the pad with pieces blown up to 5 miles away. __ ~ ~~~:~' annual basis Tunalik # 1 Downhole, the well is in good shape with sufficient plugs. Diesel fuel fills the top 4,000 feet. The well is an USGS monitor well. Wellhead components are in working condition with no problems. The immediate concern with this site is the blowing Styrofoam, but as the years progress erosion could become a major issue (Figure 42). The loose Styrofoam should be cleaned up and erosion progress should be monitored on an . It is also worth mentioning that the same type of scenario is unfolding at (another USGS well). Wave action from the reserve pit is beginning to 51 N'igure 42: Awuna wellhead with exposed wooden pilings and Styrofoam. undermine Styrofoam from the drilling pad. Tunalik #1 differs from Awuna #1 in that prevailing wind direction does not force erosion in the direction of the wellhead. Uncased Core Tests There are thirty-nine uncased core test holes. These holes were typically left filled with drilling mud and abandoned without being plugged. Drilling depths ranged between 500 and 1,500 feet depending on the purpose of the test. By nature, core tests were drilled to test soils, permafrost, or lithologic units. They were not drilled for oil or gas exploration purposes and did not encounter hydrocarbons. Many of the cores are stored in the Alaska Geologic Materials Center (Figure 43). The BLM has examined the cores and they are extremely friable. It is likely that these ~ r__.-T.~~r ~`~~ uncased core holes Figure a3: Core samples from Simpson Core Test #25, an uncased core test, are stored in the Alaska Geologic Materials Center. Barrow Gas Wells have naturally collapsed and harmlessly blended into the environment. There is no surface indication of their location and BLM has been unsuccessful in locating them during several visits to their reported location. They do not pose any potential risks. The Barrow Gas Field Act of 1984 (P.L. 98-366, 98 Stat. 468, July 17, 1984) allowed the U.S. Navy to transfer several wells to the North Slope Borough. The Navy drilled six shallow wells between 1953 and 1974 to test the natural gas potential. Between 1974 and 1982, 10 additional wells were drilled to help supplement the local gas supply. The wells were developed for use by the local government agencies and Barrow residents. The act conveyed the sub-surface estate, held by the federal government and any other interest therein, to the Arctic Slope Regional Corporation (ASRC). The BLM acknowledges the surface and sub-surface lands as conveyed and the Office of the Regional Solicitor has confirmed that the Transfer Act included the wells and well locations, and any liabilities associated with these wells are the responsibility of ASRC. 52 Plugged Wells Square Lake #1 Square Lake #1 is a Navy well that was drilled to a depth of 3,984 feet. Its primary intent was to test the Cretaceous rocks in east-west trending anticline structure (305H pg 424). No significant shows of oil were found. Gas shows were encountered in various sandstone beds between 1,600 and 1,900 feet, but otherwise the hole was dry. Upon completion, four plugs were reported to be set with the upper plug at 728 feet, well above the gas shows. Two other plugs were reported to be set in the gas zone, spanning depths of 1,640 - 1,840 and 1865 - 1934 feet. In addition to the six plugs, water and mud fill the remaining distance to the surface (Collins and Berquist, 1959). Upon successive visits to the site, BLM field crews dropped aplumb-bob down the hole and hit a solid obstruction between 8 and 10 feet. Don Meares, Northern Field Office, visited the site in August 2003 with an underwater camera and determined the solid surface to be cement. The Square Lake area is clean of debris with a few deadmen pilings (anchors) near the wellhead that could pose a ground hazard. The wellhead is open casing cut off at ground level. Umiat #2 and #5 The Umiat #2 and #5 wells were plugged and abandoned in 2002 by the COE (Figure 44). The wells were drilled on a common four-acre pad in 1947 and 1951. The purpose of the wells was to test for producing lithologies and determine petroleum quantities. Umiat #2 penetrated the Gubik Formation, Nanushuk Group (Chandler and Grandstand Formations), Topagoruk Formation and Oumalik Formation. Problems with the drilling muds were encountered while drilling Umiat #2. Analysts determined that the fresh water drilling fluid caused formation damage and the Unuat #5 well was drilled adjacent to the #2 with acable-tool rig. The well produced 400 barrels per day with the most productive sandstones in the lower Chandler and upper Grandstand. Below a depth of 1075 feet, 107 banels of crude oil from both Umiat and Simpson were used as a drilling fluid, as well as 11 barrels of diesel fuel (Robinson and Bergquist, 1956). In 2000, the Colville River threatened to erode both wellsites away. The COE took action under the FUDS program in the winter of 2001-2002 to plug, abandon and remove any surface features. The concrete lined cellar of Umiat #2 and wooden platform _• asua c +~. r iu~~lllg UF/CiYlUURS 8L UID18[ ii'. LVl from Umiat #5 were removed. Costs were approximately $25 million dollars due in part, to soil Approximately 30,000 tons of petroleum-contaminated soil was excavated. remediation. The soil was 53 transported on an ice road to the Umiat camp where it was thermally treated in. a rotary kiln to remove petroleum residues. Small quantities of PCB contaminants were unexpectedly encountered after the excavation was completed. The source of the PCBs has been linked back to the #5 well and the fluids used downhole. The ever-shifting Colville River continues to erode the north bank and is approximately 50 feet from the old wellbores. With the removal of hazardous soils, this site should not be considered a threat to humans or the environment. Umiat #3 Umiat #3, also known as Umiat Core Test #1, was spudded in December 1946 and drilled to test some of the oil bearing zones encountered while drilling Umiat # 1. The well was drilled on the northeast corner of Umiat Lake just below the hill from Umiat #4 (Figure 45). Umiat #3 penetrated the Gubik Formation and the Nanushuk Group. The Grandstand Formation within the Nanushuk Group is considered to be the primary source of oil between the depths of 258 and 514 feet. The hole produced 50 barrels per day prior to shutdown. The well was re- tested nine months later with production chopping to 24 barrels per day (Robinson and Bergquist, 1956). The wellhead consists of homemade components with a single water service type valve and is capped with a needle valve. There is no seeping present at this site, however seeps are common in the area, including an active seep in Umiat Lake. An extensive piping system is still visible. The pipes probably supplied water during the drilling phase. They connect Umiat #3 to #4 which then follow the hill from Umiat #4 to a side channel of the Colville River. Their function was to either carry water to the drilling sites or assist during the well's production phase. The overall surficial conditions including the wellhead and piping, do not pose a tlueat to human health nor the environment. BLM plugged the well in May 2004. Umiat #4 After encountering relatively poor oil shows on the first three wells, operations were suspended until 1950. Cable tool drilling rigs were introduced to determine if the fresh water muds had hindered the oil production in the previous wells (Robinson and Bergquist, 1956). Cable tool wells did not require the excavation of a cellar; therefore Umiat wells #4-#7 did not have cellars. Umiat #4 is located on top of the hill to the northeast of Umiat #3 (Figures 45, 46). The well was drilled May 1950 to a maximum depth of 840 feet. The hole bored through the Ninuluk, Chandler and Grandstand Formations. Oil was found in the upper and lower 54 Figure 45: The view from Umiat #4 looking southwest toward Umiat Lake and Umiat. Umiat #3 is located on the near shore of Umiat Lake. sandstone of the Grandstand Formation. Drilling encountered good oil shows around 300 feet with a total 500 barrels produced (Robinson and Bergquist, 1956). The wellhead consists of 11 3/-inch casing protruding 36 inches above the ground surface. The casing is capped with a steel plate. Upon removal of the cover, the hole was open to the environment. No valves or gauges are present. The well was plugged by the BLM on May 9, 2004. The well poses no risk to humans or the environment. Umiat #8 ~, Like the other wells drilled in the 1950s, Umiat #8 was drilled using cable tools. The well was spudded May 1951 and completed August 1951. It is located on top of a ridge that separates Umiat from the Bear Paw Creek valley. Drilling intention was to determine the quality and quantity of hydrocarbons in the Grandstand formation near the crest of the anticline structure. The hole encountered the Seabee, Ninuluk, Chandler, and Grandstand Forniations. The Grandstand Formation produced approximately 60-100 banels per day of oil and more than 6 million cubic feet per day of gas. The well was shut in with a gas pressure of 275 pounds per square inch. The gas was analyzed by the Bureau of Mines and determined to be 97.3 per cent methane. Brine was mixed (35 lbs of salt per barrel of water) and used in the drilling fluid to prevent freeze up. Brine solution of approximately the same ratio of salt per barrel of water was used to kill the well and set the plug while cementing casing. A total of 21,695 pounds of salt were used in the well (Robinson and Bergquist, 1956). The well was plugged May 2, 2004. Prior to plugging, the well was nicknamed the "Whistling Well" due to the gas of which was escaping through fittings and valves in the wellhead. The wellhead is easily the most complex of the 11 Umiat test wells. It consists of five valves and multiple gauges. It has several homemade components and reaches a total height of ten feet. After reporting the seeping gas in 1996, two new valves and gauges were installed in 1997. The new gauges have been checked regularly since 1998 and have consistently read 250 psi. Despite replacing the two valves and gauges, gas continued to leak from the wellhead. The largest of the leaks occurred just above the top flange where a 4-inch nipple and collar are welded together. Other leaking occurred at the fittings of some of the gauges. The wellhead is sited on a gravel pad. A series of piping extends from the wellhead to a small stock tank about 100 feet to the south. The tank probably was used as a holding tank for the oil while testing the production potential of the hole. The same style of stock tank is present in various old photographs found in the Umiat area and may be the same 55 Figure 46: Umiat #4 prior to plugging. The wellhead is located in the center of the photograph. tank. Oil from inside the tank was sampled in 2004 with test results positively identifying PCB contamination which is slightly below the level of concern. Umiat #10 Umiat #10 was spudded September 1951 and completed January 1952. This well was drilled to test the Unuat anticline and is located about a half mile northwest of Umiat #8. Total depth of the well is about 1,573 feet. When the well was bailed, it produced 222 barrels of oil in a 24-hour time span. The most productive layers occurred at 980 feet and 1,095 feet, penetrating both the Ninuluk and Grandstand Formation (Robinson and Bergquist, 1956). Also encountered were the Seabee and Chandler Formations. The hole was somewhat problematic as it caved considerably during drilling. Operations consisted of a drill rig set on a foundation of 12" x 12" timbers with a thin layer of gravel in between. Twenty-five pounds of salt mixed downhole to help lubricate the drill bit above the 650-foot marker (from the surface). More Aquagel-brine mud was used down to about 1,000 feet to keep the hole from caving. The wellhead contains two valves; a master and a gate, both are closed. The total height of Umiat #10 is approximately 10 feet. The 8 5/$-inch casing is flared and open at the top. This well was plugged May 6, 2004 (Figure 47). with Aquagel and water (per barrel) were used ~:~ :. r ~ ~, The surface near Umiat #10 is in good shape. There is no existing pad and no solid wastes. With the recent plugging of the well, it is not a risk to human health and safety or the environment. 56 Figure 47: Plugging operations at Umiat #10. May 2004.

This well is similar to a number of wells out there that was properly plugged downhole, however the upper 2000' of the well was _l eft filled with diesel to allow the USGS to conduct= permafrost temperature monitoring. Attached, in response to my request is a listing of the 20 USGS monitoring wells according to BLM's records. I have looked at our well listings and all wells are listed as P&A which is only correct for East Teshekpuk #1 which was properly abandoned including removal of the diesel this past winter season. I recommend that the current status of the remaining,_wells be changed to OBSW,_pe,ndng _.~na proggr P&A by_ BLM..

I have compiled a worksheet showing these well locations from information T compiled from our well files. I have reported the well locations in three different references;l) land coordinates by Section, Township, Range and footages from the section lines; 2) latitude and longitude coordinates, and 3) Alaska State Plane Coordinates. The three systems of reference should identify the same well location. I have not verified their accuracy to the same well location point as yet. If you should identify any discrepancies between any of these well locations, please bring them to my attention. I am not beyond making a transcription error. The BLM plugged and abandoned the East Teshekpuk #1 well and its location in 2008. We are proposing to plug and abandon the Atigaru Point #1 well in 2009 season. You should have received previous correspondence regarding that activity . Feel free to contact me on any of these issues. 1 Thank you.

The well is located 1,968 feet from the north line and 1,981 feet from the west line of protracted Section 6, Township 12 North, Range 2 East, Umiat Meridian (Latitude: 70°25'29.31" North; Longitude: 151°43'52.48" West). Alaska State Plane Coordi·nates are X = 287~561 and Y = 6,007,993, Zone 4. Elevations are: Kelly Bushing 45 feet; Ground 25 feet. Drilling related operations started with. rig-up on November 10, 1976, and terminated on February 16, 1977. The well was drilled to a total depth of 11,290 feet. The primary objectives of the well were the Sadlerochit and Lisburne Groups, with secondary interests in the Kuparuk Sandstone, Sag River Sandstone, and the basal sandstone in the Torok Formation. At the conclusion of the drilling and evaluation operations, the well was abandoned with cement plugs set at selected intervals. Husky Oil NPR Operations, Inc. supervised and directed the drilling and support operations as prime contractor for the U. S. Navy. Parco, Inc. was the drilling contractor; Parco Rig 128, a TBA Helihoist 2000, was used to drill the well. r) \ \ .J ,.;"ÜMlAT ~.("t ,__. ~o»fo r NPR-'\ ~ I "'1"......,.-""'-.- i "p~."

This early construction allowed for stabilization to occur during the summer of 1976. Field operations began on October 18, 1976, with the mobilization of construction crews to the South Harrison Bay location to prepare the pad. An Otter strip was prepared at the location and readied for service. An ice ai rstrip was constructed to accommodate C-130 Hercules ai rcraft. Rig move-in operations began on October 28, 1976. The rig, Parco 128, was stacked at the East Teshekpuk No. 1 location, which was drilled during the previous winter. The rig move was conducted using Catco Rolligons over a winter trail between the two locations. The rig move from East Teshekpuk to South Harrison Bay was completed in 19 days, with 129 total loads hauled. Rig-up operations began on November 10, 1976. Rig- up was completed in 12 days, and the well spudded at 3: 00 p. m. , November 21, 1976. Weather conditions du ring the rig move and rig-up were generally good. However, warm temperatures (+100 to +15°F), accompanied by winds of 25-30 knots for approximately four days, resulted in loss of the Otter strip and greatly hampered air transportation to and from the location. During rig-up, 20" conductor had been set at 83' and cemented to surface with Permafrost cement. A 20" annular blowout preventer and diverter lines were installed on the 20" conductor. A 17-1/2"hole was drilled from 83' to 2640' (driller's depth). The 17-1/2" hole was logged from 2638' (logger's total depth) to the bottom of the 20" conductor with the BHC-Sonic/GR log and the DIL/SP. After logging, 2600' of 13-3/8" surface casing was run and cemented back to surface with 4,300 sacks of Permafrost cement. A 13-5/8" 5,000 psi blowout-preventer stack (SRRA arrangement) was installed on the 13-5/8" split unihead wellhead. A 5,000 psi choke manifold and kill line was also installed. The 13-3/8" casing was tested to 2,500 psi and drilled out with a 12-1/4" bit. The formation below the shoe was tested to a 0.67 psi/ft. gradient. A 12-1/4" hole was drilled from 2640' to 7022'. Core No.1 was cut from 7022' to 7052' (30') and 13.6' were recovered. Drilling was continued to 7207'. Drill-Stem Test No.1 (7119-7207') was run with packers set at 7108'-7117', with no fluid recovery. Drilling was resumed to 8400'. The 12-1/4" hole was logged from 8380' (logger's total depth) to 2600' with the DI L/SP, BHC-Sonic/GR, FDC/CNL/GR/CAL, and HDT-Dipmeter. Thirty sidewall cores were attempted from selected intervals; 22 were recovered. Intermediate 9-5/8" casing was run and landed at 8370'. Two FO cementing collars were run in the string and landed at 2392' and 2199' for use if Arctic Pack procedures became necessary. The casing was cemented with 1,600 sacks of Class "G" cement containing friction reducer and retarder. Pressure rise during cementing indicated a :!:3000' column rise behind the 9-5/8" casing. 2 e e , I ¡ Blowout-preventer equipment was tested, and the casing tested to 3,000 psi. The shoe was drilled out with an 8-1/2" bit to 8410'. The formation below the shoe was tested to a 0.61 psi/ft. gradient. Drilling resumed with tight hole and lost-circulation problems. The hole was drilled to 9514' with tight spots from 8400' to 8700' and 30-90' of fill on trips. Drilling continued to 9682' when lost circulation was encountered, totaling 125 barrels of mud lost. Drilling continued to 10,154' with minor lost circulation. At 10,154' lost circulation occurred, with a loss of 350 barrels of mud. While testing blowout preventer and changing out the drilling line at 10,222', 200 barrels of mud were lost to the hole. Drilling continued with a 150-barrel mud loss while drilling at 10,322'. Drilling continued to 10,613' and Core No. 2 was cut from 10,613-10,628' (15'), recovering 13.8'. Tight hole was encountered between 9850' and 9800' on trip out with core. Drilling was resumed and an 8-1/2" hole drilled to 10,783', where lost circulation totaled 630 barrels. While drilling to 11,046', another 500 barrels of mud were lost. Drilling continued from 11,046-11,290' with no further loss of mud and minor fill on trips. The 8-1/2" hole was logged from 11 ,274' (logger's total depth) with DIL/SP, BHC-Sonic/GR log, FDC/CNL/CAL/GR, HDT-Dipmeter. A CBL/VDL/CCL/GR log was run across zones of interest behind 9-5/8" casing. Twenty-four sidewall cores were attempted and five were recovered. A velocity su rvey was also recorded. All logs were recorded on magnetic tape, and computer-log interpretation presentations were prepared using Schlumberger's synergetic log systems. A single-shot deviation survey was run while drilling. The hole was, for all practical pu rposes, "straight". I n the 17-1/2" hole, the max imum deviation at 2640' was 2-1/2°. In the 12-1/4" hole, the maximum deviation at 7026' was 2-1/2°. In the 8-1/2" hole the maximum deviation at 9514', 11,193' and 11,190' was 2°. At the conclusion of the log evaluation, it was decided to plug back and test the zones 7120' to 7190' and 5680' to 5790'. Cement plugs were placed at selected intervals in the 8-1/2" hole. Plug No. 1 was set from 10,283' to 10,083' with 90 sacks of Class "G" retarded cement. Plug No. 2 was set from 9306' to 9106' with 75 sacks of Class "G" retarded cement. Plug No. 3 was set from 8991' to 8791' with 100 sacks Class "G" reta rded cement. Plug No. 4 was set from 8424'-8324' with 70 sacks of Class "G" Neat cement. A Halliburton EZ drill retainer was set in the 9-5/8" casing at 8238' . The interval 7290' to 7120' was perforated with Schlumberger's Hyperjet II casing guns at two jet shots per foot, one shot per foot 7155-7140', for Drill-Stem Test No.2. The test was conducted with the packer at 7080' in the 9-5/8" casing and 1000' of water cushion. It is summarized as follows: Initial flow 15 minutes, initial shut-in 30 minutes, final flow 120 minutes, final shut-in 123 minutes; no blow, gradually increasing to very weak blow in final flow period; fluid recovery too small to measure, water cushion and rat-hole mud; pressures recorded at 7051' were IHP 3,950 psi, IFP 546 psi, ISIP 647 psi, FFP 549 psi, FSIP 3,173 psi, FHP 3,936 psi. 3 I I I I I I I I I I I I I I I ,I I I I e e At the end of the test, the perforations were squeezed through a retainer at 6315' (failed to set at 7035') with 65 sacks of Class "G" Neat cement. Ten sacks of cement were spotted on top of the retainer and the plug tested to 2,500 psi. The interval 5680' to 5790' was perforated with 4 shots per foot for Drill-Stem Test No.3. The packer was set at 5628' and the test conducted as follows with 1000' of water cushion: Initial flow 15 minutes, initial shut-in 32 minutes, final flow 120 minutes, final shut-in 135 minutes; very weak blow increasing slightly at the ends of both flow periods; pressu re recorded at 5741' were I H P 3,279 psi, IFP 550 psi, ISIP 1,953 psi, FFP 637 psi, FSIP 2,312 psi, FHP 3,279 psi. Recovery was too small to measure with 0.2 cubic feet of gas, trace dead oil and 2,400 cc mud in sample chambers. At the conclusion of the test, a decision was made to plug and abandon the well. An EZ drill retainer was set at 5590' and 65 sacks of Class "G" Neat cement were squeezed into the perforations at 5680' to 5790'. Ten sacks of cement were spotted on top of the retainer. The 9-5/8" casing was cut at 2412' and retrieved. Both 9-5/8" FO cementers were also salvaged. A 75-sack Class "G" cement plug was placed across the interval 2392-2289'. At 2173' the drilling mud was reversed out with water and the water with diesel, allowing the well to be used in the USGS North Slope geothermal-measu rement prog ram. The abandonment well marker was installed, and the rotary rig released at 12:01 a.m., February 8, 1977. The rig was rigged down and demobilized to Deadhorse. The drilling pad was cleaned and prepared as a staging and storage pad for Parco Rig 95. Detailed drilling information, in the form of bit records, mud summary, time analysis, and casing and cementing reports, is included in the report. 4 I e e I I I UNITED STATES DEPARTMENT OF THE INTERIOR GEOLOGICAL SURVEY SUBMIT ~ '!'RIPLICATE" (Otbeor iDstructioud on reVt~l"Se ~iùe) Form ,approV'ed.

Enroute to a total depth of 11,290 feet, rocks ranging in age from Upper Cretaceous to Pennsylvanian were penetrated. Total depth was reached on January 27, 1977 and the rig released on February 8, 1977 after performing two drill-stem tests for final evaluation of the well., A previous open-hole drill-stem test had been conducted from 7119-7207' and the same zone was retested through casing from 7120-7290' on Drill-Stem Test No.2. No producible hydrocarbons were found and the well was abandoned as a dry hole. PRE-DRILLING PROGNOSIS The well was located on the northeast flank of the Fish Creek Platform and near a seismically postulated truncation edge at the top of Jurassic rocks. The primary objectives of this well were rocks of the Sadlerochit and Lisburne Groups and the "Pebble Shale" sandstones (possible Kuparuk Sandstone equivalent). Secondary objectives were sandstones of the Torok and Kingak Formations and the Sag River Sandstone. It was expected that the normal sequence of strata present in NPRA (Cretaceous through Mississippian) would be drilled, but that the Nanushuk Group would be very thin. The tops of the Sadlerochit and Lisburne Groups (primary objectives) were expected to be approximately 9147' and 10,292', respectively. POST-DRILLING SUMMARY Drilling of the South Harrison Bay No. 1 began in the Prince Creek-Schrader Bluff Formations (Upper Cretaceous) with Cretaceous rocks extending to a depth of 7290'. The Nanushuk Group, which was expected to be very thin in this well, was found to be 2000' thick. Approximately 345' of "Pebble Shale" was expected, but found to be missing in this well. A zone in the Torok Formation (6430-6680') contained rounded frosted grains which are not common to the Torok and may represent a reworking of the missing "Pebble Shale". Hydrocarbon shows were limited to minor methane gas and scattered fluorescence until sandstones of the Torok were encountered. Two sandstone units (5677-5795' and 7123-7220') exhibiting fair to good fluorescence and cut were drill-stem tested with negative results (Appendix D). Electric log cháracteristics show these sandy zones to have low porosities. The Sadlerochit Group, which was expected at 9147', actually came in 213' lower at 9360', while the Lisburne Group, topped at 10,234', was 58' higher than predicted. 1 e . I .I I Hydrocarbon shows below the Cretaceous consisted of only scattered fluorescence and minor gas peaks in the limestones of the Shublik Formation. Some porosity, up to 15%, was noted in the Sag River Sandstone and Ivishak Formation. All computed to have high water satu rations. The Lisburne Group of carbonates had a few zones with porosities up to 3% which were void of hydrocarbons. It was deemed, after evaluation of the well, that no potential hydrocarbon reservoirs were encountered and the well was abandoned. 2 ------------------- r ~N " ..... ø c: ;;C [T1 - I ï o ("') ):::0 -; ..... o z 3: ):::0 -0 I W (/) o c: -; :x:: :x:: - ):::0 ~ ;;C 3!. ;;C ~ ..... ~ (/) _c::. o ~ z OJ ):::0 -< Z o - .~ e e 4 ..v IN OOI'CWI N T,",93(~" 0 I ~ ~~ *' ,,"- \1 ~ : \"A64' "101 T 16N-R4W ).-J ÁCope HOlkft I ~ Y 9900' " ¡' HARRIS TE~HE/(PU/( ~. -';:N BAY AKE jJ[ T's~.k · «¡ 10 pukNol TI4N·R"'W ' ,664' ' \ .....

BROCKWAY INTRODUCTION The South Harrison Bay No.1, located approximately 130 miles east-southeast of Barrow Alaska,. was drilled in protracted Section 6, T12N, R2E, Umiat Meridian, in the Naval Petroleum Reserve No.4 just prior to the transfer of the reserve to the Depa rtment of the I nterior on June 1, 1977. A suite of rocks ranging in age from Upper Cretaceous to Pennsylvanian were penetrated. Missing from the normal progression of formations found in most wells in the area is the "Pebble Shale". A zone (6430-6680') in the Torok Formation had some rounded frosted quartz grains and granules, which are not common to the Torok, and these may be reworked from the missing "Pebble Shale". Significant hydrocarbon shows were limited to sandstones of the lower Torok Formation. Two zones were drill-stem tested, both with negative results (Appendix D). The primary objectives (Sadlerochit and lisburne Groups) were void of hydrocarbons with the exception of a few scattered occurrences of slight fluorescence. Porosities varied from 5-15% and computed to be water satu rated. Two conventional cores were cut and 54 sidewall cores shot with a recovery of 27. After all information was evaluated, the well was abandoned as a dry hole.

CRETACEOUS Colville Group Prince Creek-Schrader Bluff Formations undifferentiated: 500-2377' Samples began at 500' in the South Harrison Bay No. 1 and were described as light to medium gray, silty, sandy claystones and light to medium gray siltstones to a depth of 1715'. Traces of loose sand, chert pebbles, coal chips and rare fossil fragments were observed. The electric logs indicate the presence of thin sandstones, especially above 1000'. Because of the soft natu re of the rocks and fast rate of penetration (0.2-0.6 min. per foot), these sandstones were probably decomposed and lost over the shale shakers as isolated grains. Thin bentonite stringers were noted in the interval 1380-1530'. The electric logs indicate that probably the same type samples are present from 87' (Schlumberger's casing point) to 500'. At 1715', the first recognizable sandstone was noted. Below this point, light gray, very fine to medium grained conglomeratic sandstones were interbedded with medium gray claystones and siltstones. Minor methane gas was detected In the interval 1370-2850' where background gas averaged from 50 to 100 units and individual peaks reached a maximum of 240 units at 1615' and 1720-1730'. No staining or fluorescence was noted. Anderson, Warren & Associates, Inc. (AWA) have placed the base of the Prince Creek-Schrader Bluff Formations at 2330' in the middle of a sandstone sequence. For the purposes of this report, the base has been moved downward to the bottom of the sandstone at 2377'. Their microfaunal determinations have dated the interval 500' to 950' as probable Late Cretaceous and the interval from 950' to 2330' as Late Cretaceous (Senonian) in age. Seabee Formation: 2377-3223' The Seabee Formation IS primarily a medium gray siltstone with thin sandstones and minor claystones and shales to a depth of approximately 2790'. Shales become increasingly important below this point. These shales are medium gray, soft, silty and partly bentonitic. The sandstones are generally represented by loose fine to coarse "salt and pepper" to varicolored sand grains. Some very fine grained sandstones were noted in the upper 200' of the formation. A trace of bentonitic sandstone wa.s 6 I I I I I I I I I I I I I I I I I I I e e observed from 2580-2620' and probably this bentonitic cementing agent was dispersed from sandstones below 2620' leaving only the loose grains mentioned above. Mica, carbonaceous material, chert pebbles and coal chips were common th roughout. A few scattered coal partings were noted. Bentonite stringers, which are indicative of the lower Seabee, were observed below 2790' . These sediments were probably deposited in an open marine environment and the interval 2330-3210' has been assigned by paleontological data to a Late Cretaceous (Cenomanian-Turonian) age; 2210-3376' by palynology (AWA) . Nanushuk Group (undifferentiated): 3223-5224' The upper 1000'± of the Nanushuk is characterized by a sequence of interbedded siltstones, sandstones, shales and claystones. Sandstones of the interval are tannish-gray to light gray-brown, very fine grained, silty and friable. It was not until 3485' that the first recognizable sandstone of the Nanushuk Group was observed in the samples, although some loose sand was noted in the upper 262'. Here again, it is probable that the soft matrix of clay and silt was dispersed by the mud leaving only loose sand and silt grains, most of which went through the shaker screens. The electric logs indicate that the upper 80' of the formation is a "dirty" low permeable sandstone as are most of the other sandstones in the Nanushuk. The siltstones vary in color from light gray to gray-brôwn, are soft and interbedded with other strata as mentioned above. The claystones and shales are medium gray. Traces of hydrocarbon fluorescence and cut were present in both the sandstones and siltstones throughout the upper 1000'. At 3200', background gas increased to approximately 160 units and remained at that level to a depth of 4370' where it began to decline. Some individual gas peaks, not exceeding 100 units over background, were observed. One exception was in the interval 3270-3275' where a maximum gas peak of 1,200 units was recorded. This gas consisted of 240,000 ppm C1· Below 4235', the formation becomes predominantly a medium gray, micaceous and carbonaceous shale which darkens with depth to a dark gray. Interbedded with the shales are thin, very fine grained sandstones and siltstones. Pyrite and bentonitic streaks are common throughout. Microfaunal determinations by Anderson, Warren & Associates, I nc. have placed the interval 3210-3330' into the Albian to Cenomanian and 33.30-5260' into the Albian stages. Palynology specimens are Early Cretaceous (Albian) from 3376-6090'. Torok Formation: 5224-7290' From 5224' to 5677', dark gray carbonaceous shales are the dominant lithology. At 5677', a 118' sandstone sequence with interbedded shales 7 e e and siltstones was encountered. The sandstones of this zc:me were light gray, very fine grained, subangular, carbonaceous, silty, partly calcareous, and generally tight, but had good fluorescence and cut at the top of the zone. The fluorescence and cut diminished to a trace with depth. Gas shows were recorded throughout the interval, varying from 320-400 units. This was the first indication that the gas contained components other than methane (C1). The composition of the gas at 5715-5720, as read from the mud log, was 70,000 ppm C1, 3,300± ppm C2' 1,800± ppm C3, and 1,000 ppm C4. Drill-Stem Test No.3 (5680-5790') was taken with a slight amount of gas (TSTM), water cushion and some rat hole mud recovered (Appendix D). Medium to dark gray shales with some light gray zones were present from 5795' to a dèpth of 7123'. They also had a brownish tinge in the lower portion of the section. Some thin sandstone units were present in the upper 215' with siltstone and sandstone laminations present throughout. Below 6700', there appears to be an increase in the amount of siltstone and sandstone laminations which becomes definite below 6950'. Hydrocarbon fluorescence and cut was present in the laminations and some of the shales below 6800'. Core No. 1 (7022-7052') recovered 13.6' of dark gray shale which graded to siltstone and then to a fine grained sandstone. The siltstone and sandstone exhibited a bright yellow fluorescence which appeared concentrated along fracture planes. Black chert nodules (granules?) and grains were noted below 6260' with rounded frosted quartz grains and nodules present from 6430-6680'. Chert pebbles and granules have previously been logged in the Torok Formation, but quartz grains and nodules are not usually common to the formation and may represent a reworking of the "Pebble Shale" where rounded quartz grains are representative. The "Pebble Shale" is missing in this well, but present in surrounding wells. Another interbedded sandstone, siltstone and shale sequence was present from 7123-7220'. These sandstones were gray to brownish-gray, fine to medium grained, slightly calcareous, predominantly tight. A greenish-yellow to bright yellow hydrocarbon fluorescence was observed with some residual oil present in minute fractures. Gas peaks up to 800 units were recorded in the interval 7175-7200'. Maximum components were 90,000 ppm Cl, 6,500 ppm C2' 3,200 ppm C3, and 1,500 ppm C4. The sandstone interval was tested twice (Drill-Stem Tests Nos. 1 & 2), both with negative results (Appendix D). A medium to dark gray shale was present below the sandstone interval to the base of the formation at 7290'. The Torok Formation was deposited in an open marine environment with microfaunal data establishing an Early Cretaceous (Aptian to early Albian) age which is supported closely by palynological data. 8 I I I I I I I I I I I I I I I I I I I e e JURASSIC Kinga k Formation: 7290-8876' Paleontological studies by Anderson, Wa rren & Associates, I nc. have dated the Kingak Formation as Late Jurassic to Early-Middle Jurassic for the interval 7270-8970'. This also includes the underlying Sag River Sandstone. Palynological information reports a Jurassic age to a depth of 9300' which is in the lower part of the Shublik Formation. The Kingak is composed primarily of shales that vary in color from medium gray to dark brown. Brown shales are predominant in the upper portion of the formation and have interbedded brown sideritic siltstones which occur as units up to 35' in thickness. Some thin sandstones are also present. Siderite is moderately common and occurs as nodules, thin partings and as grains and cement in the siltstones. Below 8350', the shales become darker and are medium to very dark gray with some black and dark brownish-gray. Some siltstone and sandstone laminations were observed. Glauconite, pyrite and fossil prisms (Inoceramus?) were scattered throughout the formation. Hydrocarbon shows were limited to scattered very faint cut fluorescence which occurred in both the shales and laminations. TRIASSIC Sag River Sandstone: 8876-8987' The 111' of the Sag River Sandstone is composed mainly of very fine to fine grained, subangular, siliceous sandstones with glauconite grains. They become slightly calcareous at the base. A 29-foot zone of dark gray siltstone and shale has been included at the top of the Sag River. A neutron-density cross-plot shows porosities of 10-15% in the main body of the Sag River Sandstone. It also shows water saturation of 85-100% (Appendix C). Scattered yellowish-green fluorescence was observed in the samples. As mentioned in the previous discussion, the Sag River Sandstone yielded only Early to Middle Jurassic fossils even though it is generally considered to be of Triassic age. Shublik Formation: 8987-9360' White to dark brownish-gray, argillaceous, fossiliferous limestones with interbedded shales comprise approximately 65% of the Shublik. Phosphate pellets were moderately common in the interval 9150-9200'. This upper unit of the formation is underlain by a lower unit composed of interbedded sandstones, shales and siltstones. 9 e e The sandstones were light to dark gray, fine grained, calcareous, and contain scattered glauconite grains. Traces of "patchy" poor porosity were observed. The shales were medium to dark gray and the siltstones medium to light gray. Minor gas shows were recorded in the limestone section, with a maximum peak of 180 units over a background of approximately 100 units. No fl uorescence or cut was noted. Paleontological determinations date the interval 8970-9360' as Triassic and assign a depositional environment of fluctuating inner to outer neritic open marine. TRIASSIC..PERMIAN Sadlerochit Group: 9360-10,234' Ivishak Formation: 9360-9930' Below 9360', the sandstones become siliceous and contain tripolite and chert fragments. Ivishak sandstones are predominantly fine to medium grained, but have some conglomeratic zones in the thicker units. Individual units vary in thickness to a maximum of 100' at 9600-9700'. Another thick sandstone, similar to the one above, but containing pink and green mottling was present at 9812-9880'. Spot checks through these sands indicate porosities of 5-15% and high water satu rations. Hydrocarbon shows were nil, with the exception of some faint scattered fluorescence in the 9600-9700' sandstone. Separating these two thick sandstones is a 112-foot zone (9700-9812') of dark gray to brick-red shales and siltstones and light gray to light green sandstones and siltstones. The red shales and siltstones have been called lateritic by the wellsite geologist. If· this is true, then this interval was probably deposited in a nonmarine high humidity environment. Anderson, Warren & Associates, Inc. have placed the Sadlerochit Group to a depth of 10,210' into a Triassic-Permian age and note that they were deposited in a turbid inner to middle shelf environment. Unusually high densities were recorded through the 9700-9812' zone, which approach those exhibited by limestones and dolomites. Carbonates were not noted in the samples, therefore, these high densities may have been caused by a high concentration of iron minerals. Disseminated pyrite was observed in some of the shales and sandstones of this interval. This phenomen~---- also occurs at 9500-9525' where red and green shales were observed. Kavik Shale Member: 9930-10,140' The Kavik Shale Member of the Ivishak Formation is made up of medium to dark shales with a trace of brownish-gray. I nterlaminated siltstones and sandstones were present along with scattered chert pebbles and traces of limestone and dolomite. 10 I I I I I I I I I I I I I I I I I I I . . Echooka Formation: 10,140-10,234' Light to very dark gray sandstones are the predominant lithology of the Echooka Formation. They are very fine to fine grained, slightly to very calcareous, argillaceous and contain glauconite. Thin light to dark gray shales were interbedded with the sandstones. Traces of limestone and dolomite were noted in the samples. PENNSYLVANIAN-MISSISSI PPIAN Lisburne Group: 10,234-11,290' (Total Depth) The upper 266' of the Lisburne w~~1t. massive, predominantly cryptocrystalline limestones that vary in color from white to medium gray with traces of brownish-gray. Fossils and chert are common and glauconite scattered. Thin dolomites are present to a depth of 10,350'. The limestones of this section have been called calcarenites and calcilutites, as are nearly all of the limestones below, by the wellsite geologist. Some minute fracturing with calcite filling and rare traces of pyrobitumen were observed. Thin shale stringers are indicated on the electric logs, but not noted in the sample descriptions. At 10,500', a 12-foot shaly zone is indicated on the electric logs, but was not detected in the samples. This zone has been logged as a dark maroon shale with .red interbedded siltstone by American Stratigraphic Co. Below this shale the limestones become less massive with increasing shale stringers as indicated on the electric logs. A slight increase in shales was noted in the samples which were light green to dark gray in color. The limestones appear to become more brownish-gray and less white than those of the upper section. Core No.2 (10,613-10,628') recovered 13.8' of light gray to dark brownish-gray crypto to microcrystalline limestones (calcarenites and calcilutites). They were in part siliceous and dolomitic and displayed some vertical fractu ring. Some algal pellets and nodules were observed. The upper two feet exhibited a faint brownish-yellow to yellow fluorescence. Below 10,900', dark gray streaks became moderately common. Fossils and chert are still a common constituent, but there appears to be a decrease in glauconite. Amphipora, as identified, becomes common to abundant below 10,500'. At 11, 120', the limestones become lighter colored and partly varicolored with buff, green and pink below 11 ,200'. Light green to brick-red lateritic siltstones and shales and abundant chert were observed below 11,200' to total depth (11,290'). Some soft marly limestone was present in the bottom 20'. Scattered zones of slight (not exceeding 3%) porosity were present In the Lisbu rne Group, but all were void of hydrocarbons. Anderson, Warren & Associates, Inc. have placed the Lisburne Group of this well into a Middle Pennsylvanian, or younger age. Depositional environments are depicted to be restricted shelf and lagoonal to a depth of 10,870' and open shelf and platform edge below this point. 11 t1 , STRUCTURE A study of the dipmeter log, which starts at 2624', shows a general northeast dip of 1 ° to 2°, to a depth of 4410'. From 4410' to 4910', there is a change in di rection of dip to the southeast and south with dips varying from horizontal to 8°. Several zones of anomalous dips occu r at 4350', at 4410', 4600-4680', 4715' and 4910'; possibly due to slump with minor fracturing or perhaps a zone of minor faulting with some slip and drag accounting for the changes in direction of dip. Dips read from 0° to a maximum of 11 ° in this interval. A northeast dip (0°-8°) is again present from 4910' to 5250'. At 5250-5300', an anomaly occurs which possibly indicates a minor unconformity at the top of the Torok Formation. Below this point to 5680', ?the dips vary in directionøtor some unknown reason and make an almost .360° change, but the strata "'!;-predominantly horizontal. Direction of dip is northwest to southwest below 5680', with dips beginning at 2° and increasing with depth to 15° at 6680' where it remains to the top of the Kingak Formation at 7290'. The Pre-Cretaceous unconformity is reflected at this point with the beds below becoming nearly flat-lying (1 °_3°) although maintaining a general southwest direction. The southwest direction of dip remains to total depth of the well although readings in the Sadlerochit and Lisbu rne Groups are somewhat scattered. The strata remaink' fairly flat-lying with dips not exceeding 8° and generally less than 3'0. CONCLUSIONS After evaluation· of all available data, it was deemed that no potential hydrocarbon reservoirs were present and that the well was a dry hole. The absence of sandstone development near the base of the "Pebble Shale" (Kuparuk Sandstone equivalent) and the disappointingly low porosity development in the primary objectives (Sadlerochit and Lisburne Groups) downgrades this immediate area for fu rther prospects. 12 I I I I I I I I ..

Street Anchorage, Alaska 99503 Dear Mr. 18gg: On Januar;y 28. and 29, 1977, Schlumberger ran the tinal logs on ;rour South Harrison Ba;r Well No.1. Logs included Dual- Induction, Sonic/aa-a Rq, Neutron-Density/G8IIIIIIa RaY', Dipmeter, Cement Bond- Gamma Ra;r-Casing Collar Locater and sidewall cores trom casing at 8369 to total depth ot 11,290. No ident1.f'iable correlations With the Cape Halkett or Teshepuk Lake wella could be made in the upper part ot the hole but troœ the top ot the Sag River sand at 8900' correlations With the Teshepuk Lake well were very good. The Harri- son Bq well rans 300-400' lower than Teshepuk to the top ot the Ka"lik and theD a thickened sectlOl1puts Harrison aq over 600' lower at the Echoolca and Lisburne. At the top of the Kelciktuk Harmon Bq is 625' lower than Tesbepuk. . Neutron-Densit;r cross-plots in the Sag River result in poro- si ties ranging froœ 1.0-15% and :indicate the presence ot both lime and dolomite. Water saturation ranges trom 85-100% and invasion appears quite shallow. Spot oheclœ throughout the Sadlerochit indicate that it, too, is both lime;r and dolomitic with porosities ranging from about 5% to a high ot about 1$% and water saturationa all prohibitivel;r high due to the re1ative~ low resistivities combined with the low poro- sities. Resistivit;y variations are due to porosit;y changes. The Ec:hooka and Liaburne are characterized b;r porosities avera- ging less than 3% nth a high percentage of dolomite. These low porosities preclude the possibilit;r ot the formations constituting a productive reservoir.

I e e I INTRODUCTION I The South Harrison Bay No. 1 well is located in Zone A of Naval Petroleum Reserve No.4, North Slope, Alaska. The well is located 1968 feet from the north line and 1981 feet from the west line of Section 6, Township 12 North, Range 2 East, Umiat Meridian. Drilling related operations com- menced with rig up on November 10, 1976, and terminated on February 16, 1977. I I The well was drilled to a total depth of 11,290'. The primary objectives of the well were the Sadlerochit Formation and the Lisburne Group, with secondary interests in the Kuparuk River Sandstone, Sag River Sandstone, and the Basal sand in the Torok Formation. At conclusion of the drilling and evaluation operations, the well was left in a temporarily abandoned condition, with cement plugs set at selected intervals. I I Husky Oil NPR Operations, Inc., supervised and directed the drilling and support operations as prime contractor for the U.S. Navy. Parco, Inc., was the drilling contractor and Parco Rig 128, a TBA He1ihoist 2000, was the drilling rig used. I I I I I I I I I I I I i I e e I DISCUSSION I The drilling pad at the South Harrison Bay No. 1 location was constructed during March of 1976. This early construction allowed for stabilization to occur during the summer of 1976. Field operations commenced on October 18, 1976, with the mobilization of construction crews to the South Harrison Bay location to prepare the pad. An Otter strip was prepared at the location and readied for service. An ice airstrip was constructed to accommodate C-130 Hèrcules aircraft. I I Rig move-in operations began on October 28, 1976. The rig, Parco 128, was stacked at the East Teshekpuk No. 1 location, which was drilled during the previous winter. The rig mOVè was conducted using Catco Ro11igons over an ice road between the two locations. The rig move from East Teshekpuk to South Harrison Bay was completed in 19 days, with 129 total loads hauled. Rig up operations bègan on November 10, 1976. Rig up was completed in 12 days, and the well spudded at 3:00 p.m., November 21, 1976. I I I Weather conditions during the rig move and rig up were generally good. How- ever, warm temperatures (+ 10 to + 150F), accompanied by winds of 25-30 knots for approximately four days, resulted in loss of the Otter strip and greatly hampered air transportation to and from the location. I During rig up, 20" conductor had been set at 83' and cemented to surface with Permafrost cement. A 20" annular BOP and diverter lines were installed on the 20" conductor. A 17~" hole was drilled from 83' to 2640'. The 17~" hole was logged from 2638' (logger's TD) to the bottom of the 20" conductor with the BHC Sonic/Gamma Ray log and the Dual Induction Latero10g. After logging, 2600' of 13 3/8" surface casing was run through the permafrost interval. The surface casing was cemented back to .surface with 4300 sacks of Permafrost cement. I I I A 13 5/8" 5000 psi BOP stack (SRRA arrangement) was installed on the 13 5/8" split unihead wellhead. A 5000 psi choke manifold and kill line was also installed. The 13 3/8" casing was tested to 2500 psi and drilled out with ~r a 12~" bit. The formation below the shoe was tested to a 0.67 psi/ft gradient. A 12~" hole was drilled from 2600' to 7022'. Core no. 1 was cut from 7022'- 7052' (30') and 13.6 feet were recovered. Drilling was continued to 7207'. DST no. 1 was run with packers set at 7108'-7117', with no fluid recovery. Drilling was resumed to 8400'. The 12~" hole was logged from 8380' (logger's TD) to 2600' with the Dual Induction Laterolog, BHC Sonic/Gamma Ray log, Compensated Formation Density/Compensated Neutron/Gamma Ray/Caliper log, and High Resolution Dipmeter. Thirty sidewall cores were taken from selected intervals; 22 were recovered. Intermediate 9 5/8" casing was run and landed at 8370'. Two FO cementing collars were run in the string and landed at 2392' and 2199' for use if Arctic Pack procedures became necessary. The 9 5/8" intermediate casing was cemented with 1600 sacks of Class "G" cement containing friction reducer and retarder. Pressure rise during cemènting indicated a ± 3000' column rise behind the 9 5/8" casing. I I I I I BOP equipment was tested, and the casing tested to 3000 psi. The 9 5/8" casing was drilled out with an 8~" bit to 8410'. The formation below the I I ii I e e I shoe was tested to a 0.61 psi/ft gradient. An 8~" hole was drilled to 9514' with tight spots from 8400' to 8700' and 30-90' of fill on trips. Drilling continued to 9682' when lost circulation was encountered, total- ing 125 bbls mud lost. Drilling continued to 10,154' with minor lost circulation. At 10,154' lost circulation occurred, and 350 bbls of mud were lost. While testing BOP and changing out the drilling line at 10,222', 200 bbls of mud were lost to the hole. Drilling continued with a 150 bbl mud loss while drilling at 10,322'. Drilling continued to 10,613' and core no. 2 was cut from 10,613'-10,628' (15'), recovering 14'. Tight hole was encountered between 9850' and 9800' on trip out with the core. Drilling was resumed and an 8~" hole drilled to 10,783', where lost circulation totaled 630 bbls. While drilling to 11,046' another 500 bbls of mud were lost. Drilling continued from 11,046'-11,290' with no further loss of mud and minor fill on trips. the 8~" hole was logged from 11,274' (logger's TD) with the Dual Induction Laterolog, BHC Sonic/Gamma Ray log, Compensated Formation Density/Compensated Neutron/Gamma Ray log, High Resolution Dip- meter, and a Cement Bond/Variable Density/Collar Locator/Gamma Ray log was run across zones of interest behind 9 5/8" casing. Twenty-four sidewall cores were attempted and five were recovered. A velocity survey was also recorded. All logs were recorded on magnetic tape, and computer log interpretation presentations were prepared using Schlumberger's synergetic log systems. A single shot deviation survey was run while drilling. The hole was, for all practical purposes, "straight." In the 17~" hole, the maximum deviation at 2640' was 2~0. In the 12~" hole the maximum deviation at 7026' was 2~0. In the 8~" hole the maximum deviation at 9514', 11,193', and 11,190' was 20. I I I I I I I I At the conclusion of the log evaluation, cement plugs were placed at selected intervals in the 8~" hole. Plug no. 1 was set from 10,283' to 10,083' with 90 sacks of Class "G" retarded cement. Plug no. 2 was set from 9306' with 75 sacks of Class "G" retarded cement. Plug no. 3 was set from 8991 '-8791' with 100 sacks of Class "G" retarded cement. Plug no. 4 was set from 8424'-8324' with 70 sacks of Class "G" neat cement. A Halliburton EZ Drill Retainer was set in the 9 5/8" casing at 8238'. I I I The 9 5/8" casing was perforated through the interval 7290' to 7120' with Schlumberger's Hyperjet II casing guns at two jet shots per foot. DST no. 2 tested the above perforations with no fluid recovery. The packer had been set at 7080'. A 9 5/8" EZ Drill Retainer would not set at 7035' but did set at 6315'. Sixty-five sacks of Class "G" neat cement were squeezed through the,retainer and 10 sacks spotted on top. The plug was tested to 2500 psi and held o.k. The 9 5/8" was perforated as before through the interval 5680' to 5790'. DST no. 3 was conducted with the packer set at 5628'. The formation appears to have produced a very slight amount of gas and some very small amount of water. Sample chamber fluid recovery indicated the above, as it contained slightly gas and water cut drilling mud. An EZ Drill Retainer was set at 5590'. Sixty-five sacks of Class "G" neat cement were squeezed through the retainer and 10 sacks spotted on top. I I I The 9 5/8" casing was cut at 2412' and retrieved. Both 9 5/8" FO cementers were also salvaged. A 75-sack Class "G" cement plug was placed across the interval 2392'-2289'. At 2173' the drilling mud was reversed out with water and the water with diesel, allowing the well to be used in the U.S.G.S. I I I \ iii I I e e North Slope geothermal measurement program. The abandonment well marker was installed, and the rotary rig released at 12:01 a.m., February 8, 1977. I The rig was rigged down and demobilized to Deadhorse. The drilling pad was cleaned and prepared as a staging and storage pad for Parco Rig 95. I Detailed drilling information in the form of bit records, mud summary, time analysis, and casing and cementing reports, as well as geologic descriptions, are included in the report.

Griffin, Petroleum Engineer Naval Petroleum and Oil Shale Reserves To Officer in Charge, Naval Petroleum Reserve No. 4 Subj: South Harrison Bay Well No.1, and South Barrow Well #13 - Trip Report 1. Wednesday, November 17, 1976, I left Anchorage via King Air aircraft, and arrived at Camp Lonely at 9:30 a.m. Because of fog, it was not possible to fly into the South Harrison Bay #1 well site and so I left Camp Lonely at about 3:00 p.m. by Rolligon arriving at the well site at 10:30 p.m. Upon arrival I toured the drill site, noting that Halliburton personnel were setting up to cement the 20" conductor pipe, with the casing head being set in place for welding. At this time, the drilling rig was about 80% rigged up with an estimated two more days to complete rigging up. 2. Thursday, November 18, at 10:15 a.m. I witnessed cementing of the conductor pipe with 150 sacks of perma- frost II cement. That afternoon there were no major opera- tions going on at the rig site, just hooking up of miscellaneous steam, water, and electric lines so I traveled to the "Here" airstrip 7 miles from the drill site and watched a weather station being set up there. At this time C-130 aircraft were bringing in loads of 480 sacks of cement every 4 hours. This cement is pumped into cement hoppers loaded on Rolligons and transported to the drill site. 3. Friday, November 19 the Baroid Engineer was busy mixing drilling mud for spudding. It was noted that the flanges and choke valves for the diversion lines from the casing head were the wrong size. The right ones were inadyertant- ly sent from Lonely to Barrow. .~} r:-- L t . . . Page 2 - 30 Nov 76 Griffin - Trip Report 4. Saturday, November 20, the Barroid engineer finished mixing mud and the correct flanges and valves, for the diversion lines, along with the O.C.T. test plug arrived. The 20" annular (hydril) blowout preventer was tested to 1000 psia and held O.K. After laying down the test plug the drilling nipple was rigged up and the mud flow line installed. The last of the cement was unloaded at the drill site bringing the total inventory to 4,300~sacks~ of permafrost II. ,. .f¡,; 5. Sunday, November 21, a problem was encountered in finishing the diversion lines from the casing head because the welder quit on Saturday. A welder was located at Deadhorse and flown into the So. Harrison Bay site, arriv- ing at about 10:00 a.m. With work in the diversion lines progressing, the well was spudded at 2:30 p.m. with a l7~" H.T.C. bit. Straight hole tests were run at 500' and at 1068' with ~o deviation both times. 6. Monday, November 22, drilling continued with a trip out of the hole to change bits at 1368'. The mud flow line was plugged with bentonite clay and took 5 hours (3:00 p.m. to 8:00 p.m.) to unplug. I took a trip by Rolligon to the Herc strip and observed fuel being trans- ferred from tanks brought in on the C-130's to a tank kept at the air strip and to a tank loaded on a Rolligon. Personnel seem to be environmentally conscious with splash pans being placed under nozzles during these operations and absorbent pads to wipe up spills being available if needed. 7. Tuesday, November 23, a straight hole survey was run at about 2000', 20:off. In observing mud logging operations, it was noted that samples were being taken after crossing the shale shaker and sliding into a trough made from welded barrel halves. Samples taken at this location would not be the best samples. The mud loggers apparently felt that it was too difficult (due to split drilling mud, etc.) to get to the shale shaker to take samples. Also, a sample box, as specified in the drilling plan had not been con- structed. This problem was pointed out and is expected to be corrected with a sample box being built and mud loggers instructed to take samples therefrom. II' 8. At about 1:30 p.m. Bob Smith, Husky's drilling engineer, had the driller slow up on the drilling rate from about lOOt/hr. to 60'/hr. ~ , 9. At about 6:00 p.m. with a total depth of 2504', pulled out of hole to check the bit, which was sliding. The bit was clogged with clay. After cleaning the bit off, went back in the hole and slow circulated for 1 hour to clean clay out of the hole, and then drilled to 2640'. . . Page 3 - 30 Nov 76 Griffin - Trip Report I' 10. Wednesday, November 24, pulled out of the hole to the top of the drill collars to wipe the hole out. At 8:00 a.m. Thursday ran back in the hole and circulated for 5 hours until the hole cleaned up. Pulled out of hole at 2:30 p.m. 11. Schlumberger rigged up and started in the hole at about 5:00 p.m. with sonic, gamma ray, and calipher logging tool. The hole was sloughed in at 482' and the tool would not go any further. The tool was pulled out of the hole and the centralizers removed from the logging tool. This time with some effort the logging tool went to bottom. The tool was picked up from the bottom at 2633' and logged up to 87'. 12. The logging tool came out of the hole at 7: 50 p.m. Logging tools were changed and a spontaneous potential and dual induction laterolog was run. Logging was completed at 9:45 p.m. The drilling string was run back in the hole and circulated 3 hours to clean up. r- 13. Thursday, November 25, the standpipe and rotary hose were drained and the drilling string pulled out of the hole. At 8:30 a.m. rigged up and began running 13 3/8" SS-95 casing with II centralizers. Sixty seven points of casing were run with 1 centralizer 10' above the casing shoe, skipped the 1st collar then a centralizer on the next 3 collars, then every other joint. The bottom 3 joints were thread locked with Haliburton Weld A compound. Casing was set at 2600' at 5:45 p.m. Then rigged up and ran duplex stinger on 4~" drill pipe to sting-in to the duplex float collar at the top of the 1st joint of casing. Broke circulation at 300 psia, and circulated for 2 hours to clean up. At about 10:00 p.m. began circulating cement. Four thousand three hundred sacks of permafrost II cement was used with 3500 sacks (almost twice the "calculated amount) in place at 1:00 a.m. Two stands of drill pipe were pulled and the hydril washed out. 14. Friday and Saturday, November 26 and 27, were spent mixing mud, nippling down, installing 13 3/8" blowout preventers, and nippling up on 13 3/8" casing. r 15. On Sunday, November 28, I flew to Camp Lonely and then on to Barrow. At Barrow I was met by Husky's Camp Manager, Ray ~1ills, and later toured the drill site of the number 13 well. All equipment, living quarters, generators; work shop, etc. were on location, but not yet activated and opera- tional. I was informed by Bob Singleton that this well would be spudded about December 5. Reportedly problems have been experienced in moving equipment to the well site with the old caterpillars owned by Eskimo, Inc. ¡, . . . Page 4 - 30 Nov 76 Griffin - Trip Report 16. On Monday, November 29, I flew to Camp Lonely and on to Anchorage, arriving at 2:45 p.m. 'r 17. In concluding, I was impressed with the knowledge and capability of Husky's drilling formen at the South Harrison Bay Well. Bob Smith is a graduate engineer with thirty one years experience in the oilfields and Dink Hiem, while not a graduate engineer, has twenty three years of . experience in drilling. Both men are knowledgeable and capable drilling supervisors. Parco Drilling personnel as weilwere capable, experienced oilfield hands, and drilling operations overall, as well as support operations, went smoothly during the time I was at South Harrison Bay. Rolligons are almost continuously in use with drivers often getting as little as 2 or 3 hours sleep a day. However, they seemed to prefer working these kind of hours since they are paid hourly. As previously mentioned, a weather shack was set up at the Here air strip seven miles from the South Harrison Bay Well Site and is currently manned by a single weather observer. While a fork lift driver is often in the area as well, this weather observer is completely alone at the air strip part of the time. This could be a dangerous situation. For example, should the man fall or slip outside while alone and injure himself he could freeze to death. L, 18. Barrow seems to have problems which the South Harrison Bay site does not have. Primarily operating with old worn out vehicles (trucks, etc.) and moving equipment with caterpillars which aren't dependable. ····~lf.... /,... Þ1 . f .- / I ~ Ra h M. Grif II!! I . .

The rocks are late Triassic to Early Jurassic and are restricted to the northern half of the Reserve. . The Sag River Sandstone is a sheetlike sand body that probably consists of a series of overlapping bar5. The lithology is typically light-greenish-gray glauconitic calcareous sandstone. The Sag River Sandstone becomes increasingly silty toward the south and west. At Inigok 1 and Tunalik 1, laterally equivalent siltstone and shales are present. The Sag River Sandstone also grades into equivalent calcareous and glauconitic siltstones, shales, and silty sandstones on the Barrow High. Porosity within the unit is very good in wells drilled on the Reserve. The lowest porosity, 7.3 percent, was at Ikpikpuk -1:~-t.b.e__b.tgt:Le_s_tRº-rgsilY:.1_2 ~~~e rc.ent,was j n Eas.tSJmp son 1.

Ikpikpuk 1 (480 ft, or 146 m) and Inigok 1 (343 ft, or 15 m) in the Ikpikpuk Basin. East of the Dease Inlet, the basðl "Pebble Shale·' unconformity truncates TR-3a. The truncation zone runs roughly east-west and is just north of J. W. Dalton 1 and W. T. Foran 1. West of Dease Inlet, the unit onlaps the Barrow High. Thicknesses of TR-3a at East Teshekpuk 1 and West Fish Creek 1 indicate thinning over the Fish Creek Platform. Thinning also is apparent on the flanks of the Meade Arch, as indicated at South Meade 1 and Kugrua 1. In the western half of the Reserve, the unit is thickest at Tunalik 1 and thins northeastward toward the Barrow High. Lithology and high gamma-ray curve defl ect ions wi thi n TR-3a suggest that the thinning may be due to periodic nondeposition. The TR-3a unit consists of calcareous carbonaceous shales and siltstones, silty limestones, and silty calcareous sandstones. Gl auconi te is a common accessory mi nera 1 in the sandstones, and thi n shell beds occur throughout the interval. Sand-shale ratios and clastic ratios indicate that the best sand development is in the northwestern part of the Reserve. Hi gh sand-shale rat i os at Peard 1, Wa 1 akpa·l, Wa 1 akpa 2, and Iko Bay 1 i ndi cate a source area northwest of the present shoreline. TR-3a is progressively more argillaceous toward the southeast and more calcareous toward the south. Over the Fi sh Creek Pl at form, the amount of limestone present increases significantly. At South Harrison Bay 1, the unit is mostly limestone. At Lisburne 1, with no nearby control, arenaceous limestone is indicated. Apparent lithologic anoma·l i es occur at East 5i mpson 2 where the uni tis interbedded siltstone and limestone and Drew Point 1 where the high sand count may be caused by statistical variations, or may indi.cate a small barlike body flanking the Barrow High. ~_ u~_ _._..-. __ __ . / T BASED ON SEISMIC :RPRETATION.
