Trlil STAGE July 11, 2013 GOVERNOR SEAN PARNELL Wayne Svejnoha Supervisory Minerals & Energy Specialist 222 W 7th Avenue, #13 Anchorage, Alaska 99513 Re: BLM Legacy Wells Dispute Dear Mr. Svejnoha: APR 0 l 2W con serval,ton. Division of Spill Prevention and Response Contaminated Sites Program 610 University Ave. Fairbanks, Alaska 99709-3643 Main: 907.451.2181 Fax: 907.451.2155 p� The Alaska Department of Environmental Conservation (ADEC) — Contaminated Sites has reviewed the National Petroleum Reserve in Alaska: 2013 Legacy Wells Summary Report dated February 2013, containing updated information on the status of the 136 Legacy Wells located in the National Petroleum Reserve — Alaska (NPR -A), and the draft National Petroleum Reserve in Alaska: 2013 Legacy Wells Strategic Plan dated May 2013. 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. 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.

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.

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.

A break -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 \� 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 Figure 10: Umiat is a popular stopping point for Umiat Air Force Station. In June 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. Army 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, districts, 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 U 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 purpose 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 55 -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 ti and completed as a dry hole. It was the southern most well drilled on the _ Umiat anticline. The objective was to further delineate the southern . ,, f 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 0 • 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 threat 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 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. 26 0 0 LO 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). Figure 16: J.W. Dalton with exposed conductor (left), and rat hole (right). The mouse hole (not pictured) is completely exposed. 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 current 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 0 • Figure 18: Simpson Peninsula showing well locations. 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 orange color is oil -eating casing, a 2 -inch line pipe, and four bacteria. wing valves and will likely flow oil if • 0 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 Figure 20: Simpson Core #26 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 Simpson Core Test #31 is a shallow core test drilled in 1951 to a depth of 355 feet and o collect a core to view the material at the bottom of the seep. The well does not meet standard oil and gas exploration well definitions. The casing is not cemented in place and the well is probably not capable of holding substantial pressure. The well encountered a few sands with shows and one productive sand in the Ninuluk/Seabee undifferentiated formation. In 65 hours of testing, this zone flowed oil to the surface at rates averaging 125 barrels and 2,000 - Figure 21: Simpson Core #31 is located within an 4,000 cubic feet of gas per day. active oil seep. Flowing pressure was measured at 60 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 0 Simpson Core Test #30 0 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). Figure 22: Light trash is present in the seep between Cores #30 and #30A. 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 0 Figure 23: There is no surface debris present at Simpson Core #27. 0 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 during the repair process. In an attempt to free the pipe, 73 barrels 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 '/2 -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 r 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 Figure 24: Simpson Core #29 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 threat 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. cormnon 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 1-1 33 indication of stressed vegetation down -gradient from the drill muds. Additionally, solid waste in the form 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. Figure 26: Wolf Creek #1 after adding a new ball valve to the wellhead. August 2004. 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 0 • 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. Figure 27: Wolf Creek #2 had casing cut off at ground level. 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 primary 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 0 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 through a gravel -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 • 0 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 formations. 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 '/8 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 0 0 Simpson Core Test #14A Simpson Core 414A 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. Figure 31: East Simpson #2 is partially submerged during the spring thaw. Photo taken June 2003. Kaolak #1 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. 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 0 0 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; a ball -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 Figure 33: Meade #1 wellhead. . Several pilings and light trash are present, but s 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 0 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 2004 lease sale. Near-term development is unlikely. Surfrcially, there are no concerns with this well. The well is open, 10 3/ - inch casing above ground to a height of 3 feet. It is open to the atmosphere. The area of disturbance is completely revegetated Figure 34: Titaluk #1 wellhead with wooden cellar. with no solid waste concerns. The wooden cellar is in a state of disrepair and filled with water (Figure 34). The site is clean with very little debris. There are no hazardous conditions associated with the surface. The nearest settlement is Umiat, 60 miles to the east. The well poses no risks to human safety or the environment. 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 2004 lease sale. Exploration and development is a distinct possibility within the next 20 years but it 42 0 0 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 confinned 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 oil and gas Figure 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 Ouinalik 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 Topagoruk 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 thermistor cables to be run into the well. The well is located within the Northwest planning area (see Map 2) on unleased tract that received no bids during the lease sale of 2004. Near-term development is unlikely. If left 43 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 stressed 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 dry 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, 3/ -inch pipe. The open pipe lies within a water -filled cellar. The standing water has produced nurnerous algae and other aquatic vegetation obscuring the wellbore. Surfrcial 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 dry 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 within the Northwest planning area (see Map 2). It is adjacent to a recently leased tract, 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 fonn 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, a water -filled wooden box (Figure 37) that resembles a cellar (1/4 mile east of the wellhead), and drilling muds. Atqasuk 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. • Figure 37: Drilling muds and a wooden box that resembles a cellar are located about'/ mile east of the wellhead. 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 0 • 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 3/ -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. 0 • 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 enviromnent 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 permafrost freeze/thaw cycles, the concrete has buckled in numerous places creating a partially - 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 41 was drilled in 1977. The purpose of the hole was to test the Sadlerochit Formation where it laps onto the south flank of the Barrow 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 (Burruss, 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. Surfrcially, the pad and pits are in good shape. The cellar has been backfilled D IgUR V -W. aVLLlll .7nupson iii nau its ceuar nacxtittea witu sin, 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. A plumb -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 a structural/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 a year-round airstrip and serves as a logistical base to various NPR -A activities. • 0 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 -corrosive 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 threat 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 a non -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 0 • 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 Nuiqsut 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 Atqasuk. 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 attrition has taken place. Styrofoam can be seen all around the pad with pieces blown up to 5 miles away. 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 Figure 42: Awuna wellhead with exposed wooden pilings and up and erosion progress Styrofoam. should be monitored on an annual basis. It is also worth mentioning that the same type of scenario is unfolding at Tunalik #1 (another USGS well). Wave action from the reserve pit is beginning to 51 • 0 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 ONE C _ _ r __... uncased core holes 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 0 0 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 a plumb -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 Umiat #5 well was drilled adjacent to the #2 with a cable -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 ban•els 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 from Umiat Costs were #5 were removed. approximately $25 million dollars due in part, to soil Approximately 30,000 tons of petroleum -contaminated soil was excavated. 53 remediation. The soil was 0 0 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 Uiniat #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 dropping 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 r,gure 45: rhe view from Umiat #4 looking southwest site, however seeps are common in toward Umiat Lake and Umiat. Umiat #3 is located on the area, including an active seep in the near shore of Umiat Lake. 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 surfrcial conditions including the wellhead and piping, do not pose a threat 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 #447 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 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. is Figure 46: Umiat #4 prior to plugging. The wellhead is located in the center of the photograph. 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 Formations. The Grandstand Formation produced approximately 60-100 barrels 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 • 9 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 Umiat 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 with Aquagel and water (per barrel) were used approximately 10 feet. The 8 5/8 -inch casing is flared and - open at the top. This well was plugged May 6, 2004 (Figure 47). Figure 47: Plugging operations at Umiat #10. May 2004. 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 0 APPENDIX B • 20 Wells Currently Monitored by the United States Geological Survey: NAME Atigaru Awuna* Drew Point East Simpson #1 East Teshekpuk West Fish Creek #1 Ikpikpuk Kugura Koluktak* Kuyanak Lisburne North Inigok North Kalikpik Peard Bay Seabee* South Meade South Harrison Bay Tunalik* Tulageak West Dease HOLE DEPTH(meters) 648 884 640 600 727 735 615 582 227 856 532 625 660 591 393 549 399 556 756 823 *Are also part of the CALM network (Circumpolar Active -Layer Monitoring). 57 M ICROPALEO CONSULTANTS, INC.

These samples consisted of 284 ditch and four (4) sidewall core samples covering the interval 510 to 8795 feet total depth. Thin sections were also prepared on seven (7) ditch samples from 8590 to 8795 feet total depth. This work was done as part of M.C.I. Job Number 98-108' Procedures Standard techniques were used to process the material. All samples were boiled in Quaternary -O and washed over 20 and 200 mesh screens. Frequency symbols correspond to the following numerical values: very rare (1), rare (2 - 4), frequent (5 - "' 25), common (26 - 100), abundant (101- 999) and prolific (1000+). The picked foram slides and residues are reposited at the State of Alaska Geological Materials Center in Eagle River, Alaska. Certain factors such as shelf widths, basin configuration and overall basin depths associated with Arctic Mesozoic basins are not completely understood at present. The paleoenvironments presented in this report reflect relative basinal position only and should not be tied to specific water depths. Generally, neritic corresponds to shelf or deltaic environments, while bathyal corresponds to slope or prodelta environments and w.= bathyal (starved basin) corresponds to distal (far from the source) deposition. As an example, prodelta deposits could represent deposition as shallow as middle neritic or as deep as bathyal (slope) depending on the delta type and shelf width. With a narrow shelf, a river -dominated deltaic system could build across the :shelf and the prodelta y deposits would- be in a bathyal (slope) depth. Atide-dominated deltaic system- , - ►.. associated with a wide shelf could result in middle neritic prodelta deposition. Format A listing of the age, environment, fauna and occasional lithology-comments for each biostratigraphic interval follows. A generalized summary of the well is presented in the Conclusions section at the end of the Foraminifera Report.

This suggests the presence of Carboniferous age strata within this interval. Argillite lithology is reported below 8740 feet. 23 Al Purpose and Scone Data from 129 palynology samples of the HUSKY/USN South Simpson No. 1 well are incorporated in this study. The samples consist of 122 ditch -cuttings composites and seven (7) sidewall core samples taken between 510 feet and the total depth of 8795 feet. The initial analysis was completed in April, 1977, as part of the U. S. Government's evaluation program of the NPRA. At that time, 93 ditch samples were analyzed and the species occurrences were hand -plotted in a distribution chart. The sidewall core data were published in U. S. Geological Survey Open -File Report No. 81- 1165. In subsequent years some palynological samples from the well have been reprocessed. Most of the newer preparations were examined and the occurrences of selected taxa in these samples are included. This report, therefore, provides new data and an updated format for the original data. Some of the earlier taxa designations are modified to reflect the newer taxonomic assignments that have evolved over the years since the well was first analyzed. Procedures The original samples were processed in San Diego, California, using techniques standard for the time. The chemical treatments involved the use of hydrochloric, hydrofluoric and nitric acids. The resulting kerogen residues were further concentrated by physical separation with heavy liquids and a sieving/panning technique. Permanent slide mounts were made of the residue concentrates. The coverslip mounting medium was a synthetic resin sold under the brand name of "CoverBond". Data from the species distribution charts and the more recent palynological preparations were entered in a microcomputer to compile newly formatted charts. These charts are located in the pocket. The Palynomorph Distribution Chart (Figure P-1) lists the occurrence and abundance of recorded taxa in each sample. Included on this chart are the diversity and abundance curves for the spore -pollen and the microplankton cysts. 24 { r - High Resolution Biostratigraphy Plots - Foraminifera/Palynomorphs (Figure B-1) are also provided. This chart includes additional palynology parameters in the form of a cumulative plot that illustrates the relative abundance of the nonmarine, marine and miscellaneous palynomorph components. 25 510-690' T Zone, Environment.

Marine The two samples in the uppermost part of the well are questionably assigned a Cenomanian age. The key form is the dinocyst Pseudoceratium expolitum. Absence of the typical Middle - Late Albian marker species is the basis for the tentative Cenomanian age interpretation. Negative evidence can be misleading, and it is possible that this interval is part of the Middle - Late Albian age section below. Early Cretaceous Middle - Late Albian P -M17 Marine This Albian interval is identified by the occurrences of the dinocysts Luxadinium propatulum and Wigginsiella grandstandica. The form Pseudoceratium expolitum, seen above, curainues into this section. As interpreted here, the subdivision provides for only 180 feet of Middle - Late Albian section. Given this thinness, it is possible that the Albian section continues up -hole through what has been questionably assigned a Cenomanian age. C 870-63441 Zone, Environment. Palynomorahs. Discussion.

The distinguishing aspect of this assemblage is the absence of the age restrictive Middle to Late Albian dinocyst markers. The Aptian - Albian section contains numerous rare occurrences of reworked palynomorphs. The reworked forms consist of marine and nonmarine species that range in age from the Mississippian through the Neocomian. Early Cretaceous Barremian - Aptian P -M 18a Marine The Barremian - Aptian section is a thin unit in which a significant increase in the number of dinocysts occurs.

The main component is the dinocyst, Oligosphaeridium complex (thick -wall). The absence of any other age significant forms is used to support the tentative age assignment. Possible Late Jurassic Possible Oxfordian P -M22? The sporadic occurrences of two Oxfordian dinocysts provide very weak evidence for the age assignment. These species are Chytroeisphaeridia pericompsa and Nannoceratopsis pellucida.

The Nannoceratopsis species similar to N arms onis topping at 6880 feet may be reflecting the presence of Toarcian age strata. An apparent decrease in dinocysts below 7470 feet suggests that the P -M24 zonule may top at about that depth. 7530-8410' Age Late Triassic Nonan - Rhaetian Zones • P -M26 to P -M25 Environment.

This thin marine unit contained weak dinocyst evidence that ranges in age from Albian to Cenomanian; however, the absence of more age restrictive Middle to Late Albian zonal markers is the basis for a tentative Cenomanian age. ■ The marine strata from 690 feet to 870 feet are of Middle to Late Albian age. This section, unlike the interval above, contains the important Albian dinocyst markers. ■ Aptian to Early Albian marine strata are present from 870 feet to 6340 feet. The separation of this section is based on the absence of the dinocyst markers seen in the superjacent interval. ■ The thin dinocyst-rich' interval from 6340 feet to 6500 feet is of Barremian to Aptian age. This section is typically recognized by the i� marked increase in dinocyst diversity and abundance. ■ The very thin interval from 6500 feet to 6580 feet is probably of Hauterivian age. Only sparse evidence was recovered. ■ The section from 6580 feet to 6700 feet is questionably assigned an Oxfordian age. Only very sparse dinocyst evidence for this age assignment was recorded. The interval from 6700 feet to 7530 feet is of Early to Middle Jurassic age. Certain dinocyst species topping at 6880 feet suggest the presence of Toarcian age strata at that depth. ■ Late Triassic strata of Norian to Rhaetian age are identified from 7530 feet to 8410 feet. The dinocyst evidence for this age assignment is very sparse. ■ The section from 8410 feet to 8718 feet consists of essentially nonmarine strata of.Permian? to Early Triassic age. A significant increase in spore - pollen recoveries is evident. 31 The bottom interval from 8718 feet to 8795 feet is of indeterminate age. j The palynomorph recoveries were very poor. Some evidence was seen that suggests the possible presence of Carboniferous age strata. OW 32 w. REFERENCE wr. f Witmer, R.J., Mickey, M.B. and Haga, H., 1981.

Associate Director USGS i06 National Center Reston. VA 2:092 Re: BL.M/U SGS Inactive Drilling Waste Disposal Facility Closures - Numerous Inactive Sites The Alaska Department of Environmental (ADEC) has received and completed its review of your submitted documents requesting approval for closure of BLM/USGS Drilling Waste Disposal Facilities on the North Slope in the National Petroieum Preserve Alaska. These sites have been reviewed in accordance with the ADEC Interim Site Assessment Guidance for Inactive Drilling Waste Sites. June 1991. A site visit was made in August 1994 to those sites that received public comments during, the closure public notice period: Cape Halkett, East Teshekpuk No. 1. Ikpikpuk No. 1. East Simpson No. 1. and East Simpson No. ?. The correspondence desc. ides our review procedures. puts forward the department's findings, and takes action upon the request to close numerous sites. Currently, the second draft of Alaska's new Solid Waste Regulations. 18. AAC 60. are under review. and this second draft contains a chapter on Inactive Reserve Pit closures. The closure criteria in this proposed regulation parallels the closure criteria in the 1991 Guidance Document. Closure under the 1991 Guidance Document should constitute closure under the proposed Solid Waste Regulations if they are adopted as current dratted. r'• Messrs. Allen and Devine January 13. 1.995 BUY USGS Inactive Drillinsz Waste Disposal Facility Closure approval The Review Procedure The qualitative risk screening procedure required in the above referenced document determines whether a site presents negligible levels of risk, Cr if it is a significant risk generator. a decision scheme is then emoloved to establish 1 1) whether or not there is a basis of concern, and (2) whether or nota waste site is likely to present significant risk to human or environmental receptors. The first step in this screening criteria is establishing a basis of concern: "If the waste site has released contaminants or there -are mechanism for potential releases and there are receptors nearby. then, there may be cause for concern, and the waste site should be studied further. and "If there is no release of Contamination or - no' mechanisms for potentiai releases and there are no receptors nearby. then there --is not a basis for concern and the waste site should be considered closed." The criteria that are measured at a waste site to satisfy the above logical arguments are: Evidence of release of chemical contamination at the waste site in excess of Alaska Water. Quality Standards for one or more target compounds. or Mechanism for potential release, and Proximity of the waste site to biological receptors: If either of- the first two criteria and the last criteria -are met. there is a basis for concern, and before proceeding - with Step 2. -a corrective action plan ' shall be prepared for the site which shall identify .alternative ways -to correct or mitigate -'the basis of concern: prevent its recurrence, and select. a preferred: approach. - Corrective: action alternatives shall be described at a conceptual level.., and the selection - of a preferred' approach shall be' based 'on balancing protectiveness with implementability' and cost-effectiveness. The second step determines whether contamination at a waste site present a, risk- to receptors that is significant. If risk is found not to be significant. it is considered to be "negligible." The -finding -or significant risk'is.-Lased' on the.- likelihood of exposure and the likelihood of adverse consequences of exposure: Messrs. Allen and Devine January 13. 1995 BL1%i.•I:SGS Inact:'%:e Drilling Waste Disposal Facility C:osure approval ' For risk to be considered significant, the receptors must be vulnerable to exposure, and the consequences or exposure must be 'adverse' to human or animal health or the environment," and. conversely, "If exposure is unlikely or the conseque^cos or exposure are not 'adverse,' =hen the risk is negiigibie. If risk at a waste site is signficiant. then corrective action should be taken. The criteria that are measured at a waste site to satisfy. the logical arguments above are: Exposure Criteria: Receptor a posure is considered to be likely when: Contaminant release mechanisms are judged significant . or Containment migration is iudeed significant. or One or more :Contaminants are environmentally persistent. If exrosure is found to be unlikeiv. a t:nding of negligibie risk is made on the basis of absence of a likely exaosure item. and the action plan is evaluated under the ImpacvBenefit Evaivation step. T'ne purpose of this step is to determine whether the benefits of taking a corrective action would be ?reater than the impacts or taking such a corrective action. If anv one of the exposure criteria are satisfied. a finding is made that exposure is likely. Further screening continues to evaluate Consequence Criteria. Conseauence Criteria: adverse consequences of exposure to contaminants from reserve pits are considered to be Hkely :when: (a) The duration or frequency of exposure is sufficient to cause adverse health and environmental effects. This is evaluated by reviewing human and wildlife use patterns at a t7iven waste site, waste site accessibility, and ground and surface water uses: and either r y (b) The quantity or concentration of one or more contaminants exceeds pertinent federal or state water quality criteria or standards protecting health and; or the environment.

Drilling below conductor casing at 95 feet began on March 9, 1977 and was terminated on April 18, 1977 at a driller's depth of 8,795 feet. The rig was released April 30, 1977. A suite of strata from Cretaceous to Mississippian ages were penetrated with the well ending in the pre -Mississippian argillite. Hydrocarbon shows were limited to Cretaceous and Jurassic age rocks, in which three drill -stem tests were performed. A total of 45 sidewall cores were shot with a recovery of 38. No conventional cores were taken. PRE -DRILLING PROGNOSIS The well was drilled to test two possible stratigraphic traps, one from a possible truncation of a Jurassic sandstone by the pre -Cretaceous unconformity and subsequent deposition of the "Pebble Shale" and the other from an updip pinchout of the Sadlerochit Group onto the Barrow Arch. A small structural closure was also postulated from seismic data in the Okpikruak Formation ("Pebble Shale") . A pinchout of the Lisburne Group was considered a slight possibility for hydrocarbon traps although too seismic information indicated that the pinchout was probably south of the South Simpson No. 1 location. POST -DRILLING SUMMARY Drilling of the South Simpson No. 1 has revealed that the expected pinchout of the Sadlerochit Group does not occur at this point. A 6W thickness of 347 feet was present and no hydrocarbon shows were observed. Porosities in the Ivishak Formation of the Sadlerochit Group were computed to be poor to fair and water filled. The other primary objective, the Simpson sandstone of the Kingak Formation (Jurassic), contained some gas and was tested through 1 6W perforations at 6522-6568'. An estimated 75,000 CFGPD and 1,215 feet of muddy salt water were recovered. Some component of the sandstone has greatly affected -the electrical logs resulting in very high densities and Neutron log porosities. A possible solution for this could be the presence of daphnite or limonite (Appendix D) . Porosities appear to be fair to good, but the sandstone is predominantly thin bedded and has siltstone and shale interbeds. It does not appear that the pre -Cretaceous unconformity truncated the sandstone, or if it did, only a small portion of the upper part of the sandstone is missing. Hydrocarbon shows, mainly gas, were present in the lower Torok Formation and two zones were tested through perforations at 6183-6251' and 5807-5946'. Only mud with a trace of gas was recovered. 0 M In summary, the drilling of the well confirmed the presence of several potential reservoirs, mainly the Ivishak Formation, Sag River Sandstone, Simpson sandstone and Torok Formation sandstones. The presence of hydrocarbon shows in the Torok and Kingak (Simpson sandstone) Formations indicates these rocks may be potential producers updip, north or northwest of South Simpson No. 1. Pinchouts of the Sag River Sandstone and Ivishak Formation of the Sadlerochit Group, also in a north to northwest direction, are additional possibilities for hydrocarbon accumulations. 2 BARROW 0 arrow No. I 3553 So Fl l rowNo 16 So Barrow No ?,—► a AVak 4020, r 43, 5,6,'l, 8,9, 10 ,11, So Darrow No. 12 4 14,15,17 118,19,26- "rf`. --- - Tufageak peose ` hl0 1;1'_No 1, \ _ ¢Sn Barrow fro 3 1k ti Y NO 1 015 417 DEA `��, 2900 2731 i%wi — /IVLEi � 666 { N SImOSOV.

J. R. 3 vow WELLSITE GEOLOGIST'S REPORT . BY: RONALD G.- BROCKWAY SUMMARY The South Simpson No. 1 is located in the SE 1/4 of protracted Section 22, T17N, R12W, Umiat Meridian, Alaska in the northcentral portion of Naval Petroleum Reserve No. 4, subsequently transferred to the Department of the Interior, June 1, 1977 and renamed National Petroleum Reserve in Alaska (NPRA ) . The well is situated approximately 60 miles southeast of � Barrow, Alaska. The well was drilled from a 5 -foot thick sand and gravel pad constructed on flat tundra with many shallow lakes. Two of these lakes were used; one as a source of water for the drill site and the other as a runway for support aircraft. Drilling below conductor casing (95') began on March 9, 1977, and the well was drilled to a depth of 510 feet where 20" casing was set at a depth of 495 feet. After setting casing and rigging up, drilling was resumed on March 14, 1977, and the well was drilled to 2,215 feet on March 16. Lost circulation occurred while preparing the hole for logging and casing. Sixteen -inch casing was set at 2,175 feet. Drilling resumed on March 22 with rates of penetration averaging from 0.5 minutes to 1.0 minute per foot. Lost circulation was again encounteredat 5,279 feet and 5,965 feet. Rates of penetration slowed to an average of 1.5 minutes to 2.0 minutes per foot in the interval 5500-6750', then to approximately 5 minutes per foot from 6,750 feet to 7,209 feet Lost circulation problems occurred again at 7,020 feet. After logging and setting 10-3/4" casing at 7,206 feet, drilling continued on April 9 at a rate of 2 minutes per foot to 7,700 feet. Below 7700' to ., 8795' (total depth) rates were 5 to 10 minutes per foot. The Sag River Sandstone was encountered at 7,470 feet, the Sadlerochit Group at 8,200 feet, and the Argillite at 8,741 feet. Total depth (8,795 feet - driller) was reached on April 18. No conventional coring was performed on this well. h. April 19, 20, and 21 were spent logging, sidewall coring, taking velocity surveys and plugging back in preparation for taking drill -stem tests. Three tests were performed with negative results through perforations at 6522-6568', 6183-6241', and 5807-5946' (Appendix E) . A small amount of gas, estimated 75,000 CFPD, was recovered from Drill -Stem Test No. 1 (perforations 6522-6568) . Final testing was finished on April 25 and preparations for abandoning the well and rigging down began on April 26, 1977. The rig was released on April 30, 1977. STRUCTURAL INFORMATION The South Simpson No. 1 well was drilled on the southern flank of the eastward plunging Barrow Arch, which extends from Barrow, Alaska to the Prudhoe Bay area in northcentral Alaska. The well was drilled to explore a possible small structural closure and possible stratigraphic traps in a Jurassic sand and the Sadlerochit Group. 5 Two wells were used for correlation of the South Simpson No. 1: the U. S. Navy - #1 Topagoruk, Section 25, T15N, R16W, Umiat Meridian; and the U. S. Navy - #1 Simpson S/2, Section 32, T19N, R13W, Umiat Meridian. Although all three wells begin in Nanushuk Group rocks, it was found that South Simpson No. 1 was 1,188 feet structurally higher than the #1 Topagoruk and 1,305 feet lower than the #1 Simpson at the top of the Sag River Sandstone. The top of the Argillite was 2,206 feet lower than the #1 Simpson. Argillite was not penetrated in the #1 Topagoruk.

M Sandstones occupy approximately 500 of the interval and occur as thin laminations to units 85' thick. The thicker units usually have thin shale and siltstone interbeds. They are gray to "salt and pepper" and generally very fine to medium grained. Most have poor visible porosity. Hydrocarbon shows were limited to slight staining and fluorescence and rare small gas kicks. Background gas rose from 25 units to 90 units at 1115' and generally were from 50 to 100 units downward into the upper Torok Formation. A maximum of 200 units of gas was recorded from 1185-1190'. None of the shows were considered good enough to test. Interbedded with the sandstones are soft light gray (sometimes medium gray) siltstones and claystones. Thin coal stringers are scattered throughout the entire interval, but are most common above 730'. Depositional environment for the Nanushuk was probably Middle Neritic to Upper Bathyal-. Paleontological data by Anderson, Warren & Associates, Inc. have placed the interval 510-3780' into an Early Cretaceous (Albian), (Nanushuk-Upper Torok) age. This is also confirmed by their palynological data. Torok Formation: 1777-6335' The contact of the Nanushuk Group and Torok Formation is gradational in this (and other) well and for continuity with other reports has been picked at 1777', the base of the thick sandstone sequence of the lower Nanushuk Group. Medium to dark gray, carbonaceous shales are the major component of the Torok Formation with some light to medium gray claystones observed in the �Wn upper 2,200 feet. Siltstones are present throughout the formation and occur mainly as thin beds and laminations. Thicker zones (maximum 100') are present above 3900'. Sandstones of the Torok are primarily confined to the upper 1300' and lower 1000'. Those of the upper interval are scattered, but contain the thicker units (maximum 50') . The lower 1000' is characterized by thin interbedded sandstones and shales with a few siltstones. Rarely do the sandstones of the lower unit attain thicknesses of 20' and are generally less than 10'. Sandstones of the Torok are primarily light to medium gray, very fine grained, subangular, carbonaceous and silty. A few fine grained beds are present. Nearly all sandstones exhibit varying amounts of visible porosity. Hydrocarbon shows, predominantly gas, were recorded from the sandstones throughout the lower 1000'. Some fluorescence and staining were observed in the interval 6170-6310'. Individual gas shows varied from approximately 400 units to a maximum of 1,280 units at 5990-6000'. Drill -stem tests were performed over the perforated intervals of 6183-6241' (Drill -Stem Test No. 2) and 5807-5946' (Drill -Stem Test No. 3) . Only mud with a trace of gas was recovered (Appendix E) . 7 `_fto/ Lost circulation zones were encountered at 5279' and 5965'. Possibly fracturing or faulting has occurred at these points as there appears to be anomalies present on the dipmeter log at the two zones. Other electrical logs indicate that something has definitely happened at 5945'. It is the opinion of this author that this is a fault zone and may have some relationship to the 1,280 unit gas reading at 5990-6000'. Possibly the faults are a transportation median for gases generated in the shales below. Other gas readings of 448-480 units were recorded from 5945-5965'. An Early Cretaceous (Aptian to Early Albian) age has been assigned by biostratigraphic data to the interval 3780' to 6,340' (Anderson, Warren & Associates, Inc.) . Deposition of the Torok Formation sediments occurred in an open marine environment. "Pebble Shale": 6335-6523' The top of the "Pebble Shale" has been picked at the top of a radioactive zone on the electrical logs. This is also confirmed by a change in the shale; at this point, the shales become very dark gray to black and contain floating rounded quartz grains which are typical of the "Pebble Shale". Anderson, Warren & Associates, Inc. have given the interval 6340-6520' a probable Neocomian age. JURASSIC Kingak Formation: 6523-7470' The Kingak Formation is comprised primarily of dark gray to dark gray -brown shales and gray to brownish -gray siltstones. Both are glauconitic in part. Sandstones are minor with the exception of a thick sandstone sequence at the top (6523-6697). This sandstone, informally called the "Simpson sandstone", is light gray, gray -green and gray -brown, very fine grained and contains glauconite pellets measuring up to 1.5 millimeters. Some thin beds in the sequence also have a glauconitic matrix. Interbedded with the sandstone are thin siltstones and shales. Some component of the sandstone has affected the electric logs in the zone 6520-6590'. The density log records very high densities and in one zone is greater than 3.0 grams per cubic centimeter. A high porosity of 45% to 60o is indicated on the neutron log. Daphnite and Limonite were the only two minerals found which could qualify to give these types of responses (see Schlumberger letter, Appendix D) . It is possible that the high densities in this zone have also affected the computations for porosities. Gas readings to a maximum of 1,536 units were recorded in the interval 6520' to 6700'. Porosities ranging from 9.5% to 30o were computed from porous zones on the electric logs over the interval 6526-6570'. The accuracy of the porosity calculations is questionable; visual examination of the samples indicated very low porosity. M. #90 A drill -stem test (No. 1) taken over a perforated interval 6522-6568' recovered an estimated 75,000 CFGPD and 1215' of muddy salt water. A probable Early Jurassic age has been assigned by Anderson, Warren & Associates, Inc. to the interval 6520-7660', which includes the underlying Sag River Sandstone. The rocks of this section were probably deposited in a fluctuating turbid Middle to Outer Neritic environment. TRIASSIC Sag River Sandstone: 7470-7675' Although an Early Jurassic age (paleontology) has been assigned to the Sag River Sandstone in this well, the author has placed it in the Triassic to conform with other wells in NPRA where it has been given a Triassic age. The 205 foot section of the Sag River Sandstone is composed of very light gray, very fine grained, glauconitic sandstone with a few shale interbeds near the base. No hydrocarbon shows were recorded except in the 7480-7490' sample where a very slight pale yellow crush cut was observed. Porosities, as computed from the electrical logs, varied from 11% to 18% for an average of 15.2%. All zones were water wet (Appendix C) . `® Shublik Formation: 7675-8200' The Shublik Formation is a sequence of interbedded rocks varying from shales to limestones and possibly could be divided into three units; an upper and lower limy unit and middle sandstone, shale, and siltstone unit.. The upper unit, approximately 37 feet thick, has very fossiliferous "dirty" limestones which are in part coquina. This zone also contains a brown sandstone at the top which is partly iron. stained and a light brown mottled claystone which appears to be, in part, a caliche and has some iron staining. This could be a weathered zone marking the top of the Shublik .� Formation. Interbedded calcareous, fossiliferous shales, siltstones and sandstones are 'W present in the middle unit (7712-8068') and occupy the major portion of the formation. Rare traces of dead and tarry hydrocarbon residue were present and appear to be associated with calcite -filled fractures or veins. i The lower unit (8068-8200'), also a sequence of interbedded strata as in the middle unit, has, in addition, limestone units which obtain thicknesses of 15'. These limestones are much like those of the upper unit; i.e., very fossiliferous and partly coquina, although the color becomes more gray. An added component which separates this zone from the others, is the presence of phosphate pellets which are common to the lower portion of the Shublik. 0 Two small gas kicks were recorded at 8145' (170 units) and 8170' (240 units) in the lower unit; a very slight staining and very faint cut were observed in the 8160-8170' sample. 9 Om Anderson, Warren & Associates, Inc. have dated the interval 7660-8200' as Triassic (paleontology) and 7690-8410' as Late Triassic (Norian-Rhaetion) by palynology. TRIASSIC -PERMIAN Sadlerochit Group Ivishak Formation: 8200-8547' One of the two primary objectives in the South Simpson No. 1 was the Ivishak Formation. It is characterized by conglomerates, conglomeratic sandstones and carbonaceous sandstones with coal partings and thin dark gray shale interbeds. Some red shales were observed in the zone 8260-8300'. Tripolitic chert grains and pebbles are common above 8450'. Somewhat surprising is the presence of carbonaceous quartzitic sandstones with thin beds and chips of coal in the lower part of the Ivishak. These type sandstones are not common to the Ivishak and more closely resemble Mississippian age sandstones (Kekiktuk Formation) present in the Inigok Test Well No. 1 (Sec. 34, TBN, R5W) and some wells east of NPRA. Since the depositional environments of the Sadlerochit Group have been depicted to be nonmarine to Inner Neritic (Anderson, Warren & Associates, Inc), the presence of coals may represent a deltaic sequence. Anderson, Warren & Associates, Inc. give a Triassic -Permian age to the interval 8200-8590' but note that Echooka Formation type rocks are not present. Computed porosities of the Ivishak were poor to fair (Appendix C) . The formation was void of any hydrocarbons and water saturated. The base of the Ivishak has been picked at 8547' where there is a change in color from the dark shales interbedded with the sandstones to a red silty shale and red to pink sandstones. Tetra Tech, Inc., in reports dated October 24, 1980 and March 31, 1982*, has placed a 38' interval (8550-8588) into the Kavik Member of the Ivishak Formation. It is the opinion of this author that these redbeds are more typical of Mississippian age rocks than of the Kavik Member, therefore, they have been included in the Endicott Group. The Kavik Member and Echooka Formation of the Sadlerochit Group are missing in this well; the Kavik, probably due to non -deposition and the Echooka by either non -deposition or erosion by a local unconformity. * (Tetra Tech, Inc. reports are available from the National Oceanic and Atmospheric Administration, Boulder, Colorado.) MISSISSIPPIAN Endicott Group: 8547-8741' The rocks in the Endicott Group are composed of red calcareous shales with limestone nodules, red and pink limestones, varicolored conglomerates and conglomeratic sandstones, and some red siltstones. Biostratigraphic evidence is not decisive, but Anderson, Warren & Associates, Inc. state the interval 8590-8740' is probably Carboniferous to Permian in age. 10 PRE-MISSISSI PPIAN Argillite: 8741-8795' Total Depth The top of the Argillite section has been picked on the occurrence of very dark gray to black shales with quartz veinlets and quartz filled fractures. Coal stringers and inclusions were noted in the upper 20 feet and possibly this zone may be a remnant of the Kekiktuk Formation, but coals have also been cited in Devonian age rocks. Although readings on the dipmeter are somewhat scattered, there appears to be a slight increase in dip below 8770'. In the interval 8740-8770', it appears that the dip is 7-8°, increasing to 12-140 below 8770'. Generally, steeper dips are encountered in the Argillite. No foraminifera were found below 8740'. Densospores below 8770' indicate a possible Carboniferous (Mississippian) age. Anderson, Warren & Associates, Inc. note that "...these densospores had been observed reworked throughout the well in much less frequencies. The fact that these spores may also be reworked at the bottom of the well cannot be ruled out." CONCLUSIONS Final evaluation of the data from the South Simpson No. 1 indicated that the well did not have commercial quantities of hydrocarbons. Plugs were set and the well abandoned. The Simpson sandstone section of the Kingak Formation, which had an estimated 75,000 CFGPD, was not present in the Simpson No. 1, approximately 12 miles northwest. Whether the pinchout of this sand - would be worthy of more exploration is questionable as the sandstones in the South Simpson well are generally thin bedded, "dirty" and interbedded with siltstones and shales. Although the Sag River Sandstone and Ivishak Formation were barren of hydrocarbons, it is possible that they may form a trap in an updip lo"' direction to the north and northwest. It should be noted that the Sadlerochit Group and Mississippian age rocks are missing in the Simpson No. 1 well. row yaw PERTINENT DATA AND APPENDICES Appendix A.

Son` Dipmeter and Cement Bond Log. 18 sidewall cores were shot and 13 recovered. Quality of all logs was good except for an SP drift which necessitated a couple of manual shifts in that curve. Formation tops determined by log correlations and geologist's log were: Sag River Sand 71186, Shubli.k 7675, Sadlarochit 8220, Kayak 6435 (or possibly 8l�75} and Argillite at 8750. Quantitative analysis figures in the Sag River and Sadlerochit are attached. Water resistivity computed from the SP in the Sag River was 0.13 while Rwa from the Sonic was 0.12, which approximates 20,000 ppm. Average porosity from the Sonic is 16-5,,%; and. 15.21 from the Density in the levels studied. Water saturations ranged from 87% to 100% with some shaliness present in the sand. "i In the Sadlerochit water resistivity computed 0.12 ohms from both the SP and Sonic Rwa and water saturation ranged from 847 to 100% eliminating any possibility ofhydrocarbon production_. Neutron/ Density cross -plots indicate the presence of some limestone content in the sands.

The two passes of the O/rD C on Run #2 were made with a completely different set of down -hole tools and panels and the repeatability precludes the possibility of tool. failure. Incidentally,, the engineers Earl Hosey, was moat cooperative is agreeing to make the repeat runs. This phenaasnon was now an before on the U9 S. flavy's Iko Bay #1 well in 1y75 and was never satisfactorily explained aithough I believe Bob Alger called on 1:r.: ems iieijy of Tetra Tech in Houston for a discussion. In my opinion nothing could be as dense as 3 gm/ca and indicate a neutron porosity of 609 while the sonic shown Delta T values of 70 -IW and RL is not greater than 15-20 ohms. Could it be than an element is present with high gamma ray absorptive properties and highly hydrous to give these effects?

Campbell has asked me to investigate the problems described in your letter of April 15, 1977. .as you mention it, the phenomenon observed can not be attributed to logging tool failures, but its interpretation is somewhat of a puzzle. We have contacted R. P. Alger, who ran a blank when he tried to explain a similar occurrence in the U. S. Navy's well in 1975, and we have contacted C. Clavier at our Research Center. The only two minerals we could find which exhibit at the same time a high density and a high hydrogen index are: Daphnite (a chlorite) pg = 3.08 (HI) = 41% Limonite (Iron Oxide) pg = 3.34 (HI) = 55% The most likely candidate is the Limonite. We would be very interested in knowing whether the core analysis supports our tentative answer. Please feel free to call us if you need more information. Sincerely yours, a� tnt L.

The well is located 609 feet from the south line and 451 feet from the east line of .Section 22, Township 17 North, Range 12 West, Umiat Meridian (Latitude: 70°48'24.75" North; Longitude: 154°58'54.61" West) . Alaska State Plane Coordinates are: X = 381,771 and Y = 6,145,768, Zone 5. Elevations are: Kelly Bushing 25', Ground 5'±. Drilling related operations commenced with rig -up on February 20, 1977, and terminated on May 5, 1977. The well was drilled to a total depth of 8,795 feet. The primary objectives of the well were the mid -Jurassic Kingak sand and the Sadlerochit Group, with secondary interest in possible sands in the "Pebble Shale". At the conclusion of the drilling and evaluation operations, the well was plugged and abandoned, with cement and mechanical plugs set at selected intervals. Husky Oil NPR Operations, Inc. supervised and directed the drilling and ;,,, support operations as prime contractor for the Office of Naval Petroleum and Oil Shale Reserves. Nabors Alaska Drilling, Inc. was the drilling contractor; and Nabors Rig 1, an Emsco A 800, was the drilling rig used. low bow >004 SEA 1 1 � �(C N WAINWRIGHT U G � SOUTH SNuIPSON ,iL�...

Construction work was completed on February 10, 1977, and the crews and equipment moved to another location . Rig move -in operations began on February 12, 1977. Portions of the rig, Nabors 1, had been moved to Lonely during the summer of 1976 by barge. The remainder was left at Deadhorse. Those parts of the rig at Lonely were transported to South Simpson by Rolligon, while the components at Deadhorse were flown in, using Hercules aircraft. Fifty-seven Herc loads and 15 Rolligon loads were required to move the rig to the location. Rig -up operations began on February 20, 1977, and required 17 days. The well was spudded on March 9, 1977, at 8:00 a.m. Weather conditions were generally good during rig move and rig up. Blowing snow conditions prohibited flying on three days of the move. During rig -up, a 30" conductor had been set at 95' and cemented with 360 sacks ArcticSet cement. An 18-1/2" pilot hole was drilled to 510' and opened to 26". After conditioning the hole, 20" deep conductor was run and set at 495'. The 20" was cemented to surface with 1,200 sacks of ArcticSet cement with full returns to surface. A 20" casing head and 20" annular blowout preventer and diverter lines were installed on the deep conductor. The 20" shoe was drilled out and a 13-1/2" hole drilled from 510' to 796'. While drilling from 796' to 950', 100 barrels of mud were lost. A lost -circulation pill was spotted and drilling resumed to 2215'. While tripping at 2215', the hole would not stay full. A 300 -barrel lost -circulation material pill was spotted across the zone of previous lost circulation. Partial returns were gained but were lost again. ,..., A second lost -circulation material pill was spotted and full returns regained. While conditioning the hole, circulation was again lost. A third lost -circulation material pill was used to regain circulation. After stabilizing the hole, logging operations began. The hole was logged with the Dual Induction Laterolog and the BHC Sonic/Gamma Ray log. Four barrels of mud were lost during logging. After logging, 16" surface casing was run and set at 2175'. The casing was cemented with 2,000 -- sacks of ArcticSet cement. After pumping 1,750 sacks, returns were lost. The remaining 250 sacks were pumped and displaced with no returns. A top cement job through 1" pipe was performed from 360' to surface with 300 sacks of ArcticSet cement. A 16" 5,000 psi blowout- preventer stack (SRRA arrangement) was installed on the 16" casing head. A 5,000 psi choke manifold and kill line were also WW installed. The 16" casing was tested to 2,000 psi and drilled out with a 13-1/2" bit. The formation was tested to a 0.64 psi/ft. gradient. A 13-1/2" hole was drilled from 2215' to 5279'. Lost circulation occurred at 2 5279' and 220 barrels of mud were lost. A lost -circulation material pill was spotted and circulation regained. Drilling resumed to 5965' when lost circulation again occurred, losing 439 barrels of mud. Another lost -circulation material pill was spotted and circulation regained. Drilling resumed to 6445'. After tripping for a new bit at 6445', tight hole was encountered and the hole had to be reamed to bottom from 5960'. Drilling resumed to 7020' with some tight hole on trips. At 7020', lost circulation occurred and 50 barrels of mud were lost. A lost -circulation material pill was spotted and circulation regained. Drilling was resumed to 7209'. The hole was logged with the Dual Induction Laterolog, BHC Sonic/Gamma Ray log, Compensated Formation Density/Compensated Neutron/Gamma Ray log, and the High Resolution Dipmeter. The Compensated Formation Density/Compensated Neutron/Gamma Ray log had to be rerun. Twenty-seven sidewall cores were attempted and 25 recovered. After conditioning, 10-3/4" intermediate casing was run and set at 7206'. The casing was cemented with 1,000 sacks of Class "G" cement containing turbulence inducer and retarder, with full returns while cementing. Two FO cementers were run in the casing string and landed at 2093' and 2010' for use if Arctic Pack procedures became necessary. The 10-3/4" casing was drilled out with an 8-1/2" bit and the formation tested to a 0.62 psi/ft. gradient. An 8-1/2" hole was drilled from 7209' to 8795' with occasional reaming required on trips. The 8-1/2" hole was logged from 8804' (Schlumberger's total depth) to the 10-3/4" casing shoe with the Dual Induction Laterolog, BHC Sonic/Gamma Ray log, Compensated Formation Density/Compensated Neutron/Gamma Ray log, and High Resolution Dipmeter. A velocity survey was also recorded. Nineteen sidewall cores were attempted and 13 recovered. A Variable Density/Cement Bond log was run to determine the quality of the cement across zones of interest behind the 10-3/4" casing. All logs were recorded on magnetic tape and computer log interpretations 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", with the maximum deviation of 1-3/4° occurring at 6445'. At the conclusion of the log evaluation, cement plugs were placed across selected intervals in the 8-1/2" open hole as follows: Plug No. 1 from 8250' to 8050' with 70 sacks of Class "G" cement; Plug No. 2 from 7360', across the 10-3/4" casing shoe, to 7160' with 140 sacks of Class "G". A 10-3/4" cement retainer was set at 7000' and tested to 2,500 psi. The 10-3/4" casing was perforated over the interval 6522' to 6568' at four shots per foot. Drill -Stem Test No. 1 was run over this interval with the packer set at 6447'. Gas surfaced at 10 minutes into the final flow period and flowed at an estimated rate of 75 MCFD. On reversing, 1215' of muddy salt water was also recovered. A cement retainer was set at 6420', and the perforations were squeezed with 90 sacks of Class "G" cement. Ten sacks were spotted on top of the retainer. 3 saw The 10-3/4" casing was perforated at four shots per foot as follows: -- 6231-6241', 6211-6220', and 6183-6202'. Drill -Stem Test No. 2 was run with the packer set at 6108'. The test recovered 705' of watery mud with some gas cutting. A retainer was set at 6080' and the perforations squeezed with 90 sacks of Class "G" cement. Ten sacks of cement were spotted on top of the retainer. The 10-3/4" casing was perforated at four shots per foot as follows: 5903-5946'1 5846-5856', 5807-5816' . Drill -Stem Test No. 3 was run with the packer set at 5737'. On reversing out, a small amount of gas was recovered ahead of the water cushion. Four barrels of rat -hole mud were also recovered. A retainer was set at 5700'. The perforations were squeezed with 90 sacks of Class "G" cement, and 10 sacks were spotted on top of the retainer. The 10-3/4" casing was cut at 2115', recovering both FO cementers. A 70 -sack ArcticSet cement plug was spotted at 2005', and the mud reversed out to water at 1795' . The well began to flow back, and the water was circulated out with mud. Lost circulation occurred and 330 barrels of mud were lost. After regaining circulation, a 300 -sack Class "G" cement plug containing 2% calcium chloride was pumped. Eighty-five sacks were down -squeezed around the 10-3/4" stub and 215 sacks spotted above the stub with full returns. A second Class "G" plug of 500 sacks was spotted at 500' in the 16" casing. A final surface plug of 21 sacks ArcticSet .. cement was placed in the top 20' of the 16" casing. The abandonment marker was set and the rig released April 30, 1977, at 3:00a.m. The rig was rigged down and stacked on location` for the summer. Detailed drilling information, in the form of bit records, mud summary, time analysis, and casing and cementing reports, is included in the body of the report. 05 Now Furor Q-311 C SUBMT IN TRIPLICATE• Form approved.

Casing purchased by the U. S. Navy prior to Husky's involvement on NPR -4 was utilized when possible to reduce on -hand inventories. The casing was programmed as follows: 30" conductor at 100'±; 20" surface casing at 500'; 1611 casing at 2500'; 10-3/4" casing at 7100'; 7" liner run to a total depth of 8670' if needed for testing purposes. Actual casing run was 30" conductor at 95'; 20" surface casing at 495'; 16" casing at 2175; and 10-3/41T casing at 7206'. The use of a 7" liner was not necessary. The 10-3/4 tv casing was cut at 2015' and recovered back to the surface. The well was plugged back to the surface inside the 16" casing when abandoned. tw* 33 �Mw I N%w1v CASING OR LINER CEMENT JOB Lease Naval Petroleum Re -serve No.4 Well SO- Simpson No. 1 Date March 12, 1977 Size Casing 201" Setting Depth 495' — Top (liner hanger) Hole Size 26" — " Mud Gradient .53 psi/it (10.2 ppa) Viscosity 40 Casing Equipment 11 duRlex shoe, float located feet above shoe, (DV, FO) collars located at f eel and f eel. centralizers located scratchers located Liner hanger and pack off (describe) Miscellaneous (baskets, etc.) 34 Cement (around shoe) No. Slurry Slurry Sacks Brand Type Additives Volume (1 A200 -Dowell Arcticsel 1380 --cu f t (2) Cement through (DV, FO) Collar at- feet No. Slurry Slurry Sacks Brand Type Additives Volume (3) (4 MAW 34 ffn CASING OR LINER CEMENT JOB tll� LeaseNaval Petroleum Reserve No. 4 Wei!

The well is located 609 feet from the south line and 451 feet from the east line of Section 22, Township 17 North, Range 12 West, Umiat Meridian. Drilling related operations commenced with rig up on February 20, 1977, and terminated on May 5, 1977. The well was drilled to a total depth of 8795'. The primary objectives of the well were the Mid Jurassic Kingak Sand and the Sadlerochit Group, with secondary interest in possible sands in the Okpikruak Formation. At the conclusion of the drilling and evaluation operations, the well was left in a temporarily abandoned condition, with cement and mechanical plugs set at selected intervals. Husky Oil NPR Operations, Inc., supervised and directed the drilling and support operations as prime contractor for the Navy. Nabors Alaska Drilling, Inc., was the drilling contractor; and Nabors Rig 1, an Emsco A 800, was the drilling rig used. i Im DISCUSSION 0� Field operations at the South Simpson No. 1 location commenced on December 30, 1976, with the mobilization of construction crews and equipment required to build the drilling pad and an ice airstrip to accommodate C-130 Hercules aircraft. Construction work was completed on February 10, 1977, and the crews and equipment moved to another location. Rig move in operations began on February 12, 1977. Portions of the rig, Nabors 1, had been moved to Lonely during the summer of 1976 by barge. The remainder was left at Deadhorse. Those parts of the rig at Lonely were transported to South Simpson by Rolligon., while the components at Deadhorse were flown in, using Hercules aircraft. Fifty-seven Herc loads and 15 Rolli- gon loads were required to move the rig to the location. Rig up operations began on February 20 1977, and required 17 days. The well was spudded on March 9, 1977, at 8:00 a.m. Weather conditions were generally good during rig move and rig up. Blowing snow conditions prohibited flying on three days of the move. During rig up, a 30" conductor had been set at 95' and cemented with Arctic - set cement. An 18 1/211 pilot hole was drilled to 510' and opened to 26". After conditioning the hole, 20" deep conductor was run and set at 495. The 2011 was cemented to surface with 1200 sacks of Arcticset cement with full returns to surface. A 20" casing head and 20" annular BOP and diverter lines were installed on the 20" deep conductor. The 20" shoe was drilled out and 13 1/2" hole drilled from 510' to 796'. While drilling from 796' to 950', 100 barrels of mud were lost from seepage. A lost circulation pill was spotted and drilling resumed to 2215'. While tripping at 2215' the hole would not stay full. A 300 barrel LCM pill was spotted across the zone of previous lost circulation. Partial returns were gained but were lost again. A second LCM pill was spotted and full returns regained. While conditioning the hole, circulation was again lost. A third LCM pill regained circulation. After stabilizing the hole, logging operations began. The hole was logged with the Dual Induction Laterolog and the BHC Sonic/Gamma Ray log. Four barrels of mud were lost during logging due to seepage. After logging, 16" surface casing was run and set at 2175'. The casing was cemented with 2000 sacks of Arcticset cement. After pumping 1750 sacks, returns were lost. The remaining 250 sacks were pumped and displaced with no returns. A top cement job through 1" pipe of 300 sacks of Arcticset cement was done from 360' to surface. A 16" 5000 psi BOP stack (SRRA arrangement) was installed on the 16" casing head. A 5000 psi choke manifold and kill line were also installed. The 16" casing was tested to 2000 psi and drilled out with a 13 1/2" bit. The formation was tested to a 0.64 psi/ft gradient. A 13 1/2" hole was drilled from 2215' to 5279'. Lost circulation occurred and 220 barrels of mud were lost. An LCM pill regained circulation and drilling resumed to 5965' when lost circulation again occurred, losing 439 barrels of mud. Another LCM pill was spotted and circulation regained. Drilling resumed to 6445'. 7 -0 - boo MW After tripping for a new bit at 6445', tight hole was encountered and the bit had to be reamed to bottom from 5960'. 'Drilling resumed to 7020' with some tight hole on trips. At 7020' lost circulation occurred and 50 barrels of mud were lost. An LCM pill regained circulation and drilling resumed to 7209'. The hole was logged with the Dual Induction Laterolog, BHC Sonic/Gamma Ray log, Compensated Formation Density/Compensated Neutron/ Gamma Ray log, and the High Resolution Dipmeter. The FDC/CNL/GR log had to be rerun. Twenty-seven sidewall cores were attempted and 25 recovered. After conditioning, 10 3/4" intermediate casing was run and set at 7206'. The casing was cemented with 1000 sacks of Class "G" cement containing turbulence inducer and retarder, with full returns while cementing. Two FO cementers were run in the casing string and landed at 2093' and 20101 for use if Arctic Pack procedures became necessary. The 10 3/4" casing was drilled out with an 8 1/2" bit and the formation tested to a 0.62 psi/ft gradient. An 8 1/2" hole was drilled from 7209' to 8795' with occasional reaming required on trips. The 8 1/2" hole was logged from 8804' (logger's T.D.) to the 10 3/4" casing shoe with the Dual Induction Laterolog, BHC Sonic/Gamma Ray log, Compensated Formation Density/ I bw Compensated Neutron/Gamma Ray log, and High Resolution Dipmeter. A velocity survey was also recorded. Nineteen sidewall cores were attempted and 13 recovered. A Variable Density/Cement Bond log was run to determine the quality of the cement across zones of interest behind the 10 3/4' cas- ing. All logs were recorded on magnetic tape and computer log interpretations ism were prepared using Schlumbergeris Synergetic Log Systems. A single shot deviation survey was run while drilling. The hole was, for all practical purposes, 11straight", with the maximum deviation of 1 3/40 occurring at 6445'. At the conclusion of the log evaluation, cement plugs were placed across selected intervals in the 8 1/2" open hole as follows: Plug No. 1 from 8250' to 8050' with 70 sacks of Class "G" cement; Plug No. 2 from 7360' to 7160' with 140 sacks of Class "G" across the 10 3/4" casing shoe. A 10 3/4" cement retainer was set at 7000' and tested to 2500 psi. The 10 3/4" casing was perforated over the interval 6522' to 6568' at four shots per foot. DST No. 1 was run over this interval with the packer set at 6447'. Gas surfaced at 10 minutes into the final flow period and ism flowed at an estimated rate of 75 MCFD. On reversing, 1215' of muddy salt water was also recovered. A cement retainer was set at 6420', and the perforations were squeezed with 90 sacks of Class "G" cement. Ten sacks were spotted on top of the retainer. The 10 3/4" casing was perforated at four shots per foot as follows: 6231'-6241', 6211'-6220',, and 6183'-6202'. DST No. 2 was run with the packer set at 6108'. The test recovered 705' of waterymud with some gas cutting. A retainer was set at 6080' and the perforations squeezed with 90 sacks of Class "G" cement. Ten sacks were spotted on top of the retainer. The 10 3/4" casing was perforated at four shots per foot as follows: 5903'-5946'� 5846'-585619 5807'-5816'. DST No. 3 was run with the packer set at 5732'. On reversing out, the test recovered a small amount of gas ahead of the water cushion. Four barrels of rat hole mud were also recovered. A retainer was set at 5700'. The perforations were squeezed with 90 sacks of Class "G" cement, and 10 sacks were spotted on top of the retainer. The 10 3/4" casing was cut at 2015', recovering both FO cementers. A 70 - sack Arcticset cement plug was spotted at 2005' and the mud reversed out to water at 1795'. The well began to flow back, and the water was circu- lated out with mud. Lost circulation occurred and 330 barrels of mud were lost. After regaining circulation, a 300 -sack Class "G" cement plug con- taining 2% calcium chloride was pumped. Eighty-five sacks were down - squeezed around the 10 3/4" stub and 215 sacks spotted above the stub with full returns. A second Class "G" plug of 500 sacks was spotted at 500' in the 16" casing.
