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

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

ADEC has also reviewed the response by the Alaska Oil and Gas Conservation Commission (AOGC). We concur with the response by AOGC and have no further comment regarding the priorities. We do have comments about the investigation and cleanup plans presented in the report. With this letter we are outlining regulatory requirements related to the environmental work that is proposed and required as part of these cleanups. ADEC is concerned that the 2013 Legacy Wells Strategic Plan prepared by the BLM does not include either assessment or the contingency for assessment of known,likely, or unknown but possible contaminant releases. In addition,BLM plans for surface cleanup of these wells should be made clear in the plan. At least one of these legacy wells has extensive PCB contamination and has resulted in a multi-year cleanup totaling tens of millions of dollars. At others, solid waste disposal practices have resulted in releases to the environment with estimated cleanup costs in the hundreds of millions. Known releases documented in the records we reviewed include crude oil,gasses,refined oil and fuel, drilling fluids that include various organics,metals, and other chemicals, and unknown contaminants from drums and other containers observed to be damaged and abandoned at the various well sites. There are 13 legacy well sites with known releases currently on the DEC contaminated sites list. Many of these are in the process of being addressed, cleaned up, and closed. From our limited records review there are 15 additional legacy well sites with confirmed releases. These should be prioritized for initial records reviews and then added to the BLM contaminated sites list under our cooperative agreement. Suspected releases include fuel releases from operations, storage, and fuel spills at the sites,impacts to various surface water bodies from spilled fluids during drilling and breaches of containment at reserve and flare pits, continued surface runoff from drilling fluids uncontained at several sites, and down-hole substances that were ejected from the holes over time or during blowouts or drilling operations. , Wayne Svejnoha 2 July 11, 2013 The BLM plan to address these known, suspected, and unknown releases at legacy well sites is notably absent from the documents presented to date. The three primary regulatory agencies that need to be involved in the plan are ADEC —Contaminated Sites,Alaska Oil& Gas Conservation Commission, and ADEC —EH/Solid Waste. Other agencies will need to be consulted as well. Below we provide recommendations for a coordinated plan using the Uniform Federal Policy for Quality Assurance Project Plans (UFP-QAPP) that will involve all of the regulatory agencies in one coordinated manner. This will allow BLM to address these sites in a consistent and coordinated project which fulfills all of the regulatory requirements so that the sites do not need to be re-visited in the future when they are closed after this project. Attached are our comments on each specific well. The acronyms used on the list include terms that are typically used in a CERCLA type investigation however they are also suitable for investigations conducted under the State of Alaska cleanup rules. These include the following; Historical Records Review (HRR) This is recommended for almost all of the well sites. Much of the infotmation 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. r_•\ CP A A\re\FAQ>.t Fn.dl;tiPe\ FPAAPrai A n.nriPc\nni\RIM\Proiects\Leeacv Wells\711 13 Letter to BLM on Legacy Wells.docx Wayne Svejnoha 3 July 11, 2013 Please review the attached list of specific sites.

The following legacy well was plugged to surface before the cessation of plugging operations on Apri121, 2008: Ati~aru Point Well No. 1 The well was drilled in 1977 on Federal NPRA lands at Atigaru Point on the Beaufort Sea coast as part of the USGS exploration efforts in the National Petroleum Reserve -Alaska. Due to its close proximity to the Beaufort Sea coast and prevailing winds, significant shoreline erosion had advanced into the well location requiring the BLM to complete plugging and abandonment of the wellbore and well site. The well was left suspended and plugged back to 2,255 feet with diesel left in the wellbore. The USGS had been actively using the well for permafrost temperature measurements prior to 2009. Diesel fuel inside the wellbore had been used as a non-freezing medium to aid in conducting the temperature measurements. During well plugging operations, approximately 14,400 gallons of diesel fuel was displaced with NaCI (salt) saturated water prior to completing final plugging operations. The NaCI water was then evacuated from the casing down to a depth of 125 feet below ground level (BGL) and an inflatable plug was run and set at this depth using nitrogen pressure from the surface. Cement was mixed at 15.8 ppg and dumped on top of the plug filling the casing to within 15 feet of the surface. The frozen earth around the wellhead was excavated down to 19 feet BGL, the wellhead was cut off 18 feet BGL, an identification plate was welded onto the cut off casing, and the excavated hole was backfilled with clean dirt to four feet about ground level. ~~ ~ l ~ ~ F{ ,,. ,. , Carp Sar,TN bAY .e._.._.y.. t~ i. ., ti _~ ~ ~ ,.., e.~ - ~ a~ ~ - ~ - -- . ~ - ~ ' ~ . ~ ~ e ~~ i ~ ~ ,y, ~ ATIGARI.I pOfNT N4.1 i _y z} J 1 ~ ~ ~ j ) t ~ ~.

Tom Maunder, PE AOGCC 4/15/2009 F'GTROLEUM NENS WEEK OF MARCH 22, 20n9 • S A F E T Y & E N V I R O N MEN T BLM starts work on Atigaru Point well Cleanup eflorrs begin on third in program to prevent environmental damage at 'legacy wells'; funding uncertain fm- fourth well By ERIC UDII Peuroleum News The federal govemmem is tackling another decades-old well site that poses a threat to the em~imnment hecause of eroding coastlines and thawing per- mafrost on the Noah Slope. The Bw~eau of Land Management in late February began remediation work wr the Atigaru Point No. I well site. situated some 30 miles northwest of Nuigsut at the tip of a peninsula in the National Petroleum Reserve-Alaska that juts into Harrison bay. Atigaty is dte third effon in a BLM pro- gram to prevem "legacy wells" across NPR-A fran damaging the environment. Like Atigaru, the previous wells also sat near coastlines. Receding coastlines threaten to dump the contents of these well sites, which con- tain diesel fuel and drilling mud. into near- by lakes, oceans or bays on the Nonh Slope. This changing landscape put Atigaru in a precarious situation. Naval crews considering drilling loca- tions in Naval Petroleum Reserve No. 4 in the late 1970s, the final years before the area became known as NPR-A, ultimately sited an exploration well as far out on the tip of Atigaru Point as possible. hoping to reach a geologic formation encountered by a well to the .vest and the Ptvdhoe Bay field farther to the east. The U.S. Navy eventually drilled Atigam in 1977 to a total depth of 1 I.S3S feet. Today, the eroding coastline in the Atigam area has turned the well site from a peninsula to an island, and a "major sum- mer storm" could potentially cause "low- lying areas' to crumble, dumping drilling mud and diesel fuel into the water, accord- ing to 6LM. The cleanup effort began Feb. 27 and is slated to ton through mid-April. BLM expects the project to cost about S15 million. with funds redirected from within the agency last fall in an emergency request outside the normal funding cycle. The work involves excavating oil- based drilling mud. which is also believed to contain heavy metals, from the resen•e pit at Atigaru Point and hocking it to the Nonh Kalikpik No. 1 well site about 1S miles to [he southwest Crews will also drain some 14,000 gallons of diesel fuel currently stored inside the Atigaru well bore to prevent fi~eezing. BLM hired Marsh Creek LLC to cane nut the work. Nearing end of project BLM, an arm o(the U.S. Departmem of the Interior, has been managing NPR-A legacy wells Sot' decades, but only began focusing on emergency cases over the past few years. The recent push began in adventurous fashion in 2005, when 6LM crews set out to remediate the J.W. Dalton No. I well nosh of Teshekpuk Lake. The L'.S. Geological Sun~ey drilled the well LS00 feet from the 6eaufort Sea coastline in 1979. In September 2004 crews discov- ered the coastline had eroded all the way back to the well and rushed to clean up the site before waves crashed over the area. Following work at 1. W. Dalton, 6LM began prioritizing other legacy wells by the likelihood each might become an envi- romnental hazard through the end n( the decade. The program continued last winter with the East Teshekpuk No. I well, located along the eastern edge of Teshekpuk Lake. Marsh Creek also cleaned up the East Teshekpuk well. After finishing Atigaru Point this year. BLM hopes to address the Drew Point No. 1 well. northwest of Teshekpuk Lake, but funding for the project remains uncer- tain. 6LM received 5320 million from the American Recovery and Reim~estment Act, also known as the stimulus bilk but the money hasn't been appropriated for specific projects, according to Wayne Svejnoha, environmental program man- agerfor BLM in Alaska. Drew Point is the last of the legacy well sites helieved to he an immediate threat to the environment because of coastal erosion. After Drew Point. 6LM does not anticipate having [o address another legacy well for at least a decade. Svejnoha said. although several well sites further inland could require remediation sometime in the future. Possible candidates include the Tulageak and West Dease wells. east of Barrow. In excursions behveen 1944 and 1953. and between I97S and 1982, the U.S. Navy and the USGS drilled 136 wells in what is now the National Petroleum Reserve-Alaska. 6LM believes 41 of these wells could "pose a potential risk M the enviromnent" and has cleaned up 13 since 2002. The agency hopes to tackle 13 over the next five or six years. • Conrad Eric LiJji ut 9n7-52?-9459 ar elitlji~ ~penrolevumems.com • t ) 8 ' ~ ~ ~ ~ ~-~, ' ~ ~ ~~ ~ ~ ~~ ~- ,~` SARAH PAUN, GOVERNOR +..~ ...~ ~4,.~ ~.., 1-~~ ~ ._-...~ E_. 1_t ~..~ ~ ~-~~~ ~.i ~ ~ C..~:.~.~ ~.~ ~ ~ ~ ~..a ~ ALASS-A OII.

The well is currently suspended and requires diesel to be removed from the wellbore and a surface plug set in the 13.375" casing to meet the P&A requirements of the BLM and the Alaska Oil and Gas Conservation Commission (AOGCC). Attachments 1 and 2 show the current status and proposed post abandonment configuration of the well, respectively. The proposed P&A work will be conducted as a stand alone self sufficient operation and any restoration of the wellsite will be conducted at a later time. In order to complete the P&A of the well in accordance with BLM and AOGCC regulations, the following P&A program is necessary. Plug and Abandonment Procedure 1. Procure all necessary approvals for the work from the BLM, AOGCC and North Slope Borough. 2. Mobilize all necessary equipment and personnel to the Atigaru #1 location. The anticipated equipment and personnel complement is the following: Personnel: Working supervisor (1) Well specialist (1) Cementer (2) Equipment operators (2) Roustabouts (2) Boiler/vac unit hand (1) Equipment: Batch cementing unit, 50 bbl Bulk cement tank w/ 175-200 sacks permafrost cement Backup centrifugal pump Vac unit Open top tanks Waste transport tanks NaCI sack for brine Forklift Excavator Spill Kit Pipe, Hoses, Valves, Fittings as Needed Tools as Needed 3. A minimum of 24 hours before P&A operations work commences, notify the BLM and AOGCC North Slope representatives of the plan to start well work. 4. Excavate around the wellhead to a depth sufficient to access the 20" bradenhead side outlets. Do not make the excavation any larger than necessary. 1 i • 5. Install a well enclosure over the well and cellar. Apply heat to warm the well. 6. Verify that there is no pressure on the 13.375" casing. This condition is extremely unlikely but check anyway. Check 20" bradenhead side outlets for evidence of cement to surface. Remove abandonment cap and flange with 4" pipe and valve from top of wellhead. Verify diesel depth below surface. 7. Clean up 20" bradenhead flange and install a circulating spool/riser on the wellhead. RIH with 200' of 2" hose with 5' of 2" pipe for weight on the end, hang off same. 8. Batch mix 325 bbl 9.3 ppg. NaCI brine in seven (7) batches for diesel displacement. Gravity feed or slowly pump at low pressure 9.3 ppg brine down hose. Take diesel returns out circulating spool side outlet and into open top tank. Monitor returns to ensure that diesel/brine emulsion is not taken as returns. Regulate brine flow at the wellhead and continually monitor flow lines for integrity. Continue this process until all 320± bbls of diesel are circulated out of the well. Collect a sample of the diesel for analysis and store the diesel in fuel storage tanks for transport back to Deadhorse and recycling. 9. POOH with hose and rig down circulating spool. 10. Run a gauge ring in the 13.375" casing to confirm casing condition for setting a bridge plug. Set a bridge plug at 200' in the 13-3/8" casing. The bridge plug will be a bottom type cement wiper plug scored to allow fluid past and set with a weighted sinker bar on rope. POOH with sinker bar. 11. Rig up circulating spool and RIH with 2" hose to 200' and hang off same. 12. Rig up to cement well. Load batch mixer with fresh water and retarder, temperature to be specified by cementers. Batch mix a 30 bbl, 15± ppg permafrost cement plug and pump cement down the 2" hose taking returns out circulating spool into an open top tank. 13. Collect cement rinsate in a separate tank from the well returns tank to segregate Class I waste from Class II waste. Send waste fluids for injection disposal at approved North Slope facilities. 14. Excavate well cellar to at least 10' below sea level (approximately 17' below grade). Cutoff wellhead a minimum of 7' below sea level and as deep as possible in excavation. Check to make sure 20" x 13-3/8" annulus is cemented to surface. Top off annulus with cement, if necessary. 15. Weld a minimum ~/a" thick, 24" square steel plate on the 20" casing with the following information bead welded on the plate: Operator: Husky/USN Well Name: Atigaru Point #1 Location: 1925' FEL, 1472' FNL Sec 19, T14N, R2E, UM API: 50-103-20008 APTD: 100-104 Leave a weep hole in the well identification plate. 16. Backfill the excavation and mound the soil by 10°Io extra to account for summer thaw subsidence. 2 C~ 17. Demobilize all well P&A equipment and personnel to Deadhorse and beyond. 18. File well completion report with photos documenting well P&A work for both the BLM and the AOGCC. Waste Management Solid wastes generated during the plug and abandonment project including the wellhead and cutoff casings will be backhauled and disposed of in the North Slope Borough Landfill. Diesel recovered from the well will be transported back to Deadhorse in fuel tanks and recycled. Well returns from cementing operations will be transported back to Deadhorse in secure tanks and taken for injection disposal at one of the North Slope disposal facilities.

Commission Anchorage Enclosed please find our Application for Sundry Approvals (Form 10-403) for the Atigaru Point No. 1 well (2copies) with P+A Procedure, Pre-P+A wellbore diagram, and Post-P+A wellbore diagram. We propose to complete the final plugging and abandonment to surface of the Atigaru Point #1 well. The well was drilled in January to March 1977 to a depth of 11,535 feet. The well was properly plugged backup into the 13-3/8" intermediate casing (SA 2,370') with multiple (5) cement plugs. The top of the shallowest plug is located at 2,255 feet. It is an active USGS monitoring well with the upper 2,155 feet filled with diesel fuel. The diesel provided anon-freezing, non- corrosive medium that enables temperature data collection. Atigaru Point No. 1 well was drilled on the shores of Harrison Bay, Beaufort Sea. Due to its close proximity to the coast line shore and prevailing winds, significant shoreline erosion has advanced into the well location requiring us to complete the plugging and abandonment of the wellbore and well site during the next North Slope access season. If you have any questions or require further information, please contact Thomas Zelenka at (907) 267-1469.

Cathy and Steve, I have received a message from BLM regarding their plans to plug and abandon another "old" well in NPRA, Atigaru Point #1 (100-104). This well is similar to a number of wells out there that was properly plugged downhole, however the upper 2000' of the well was left filled with diesel to a]_low the USGS to conduct permafrost temperature monitoring. Attached, in response to my request is a listing of the 20 USGS monitoring wells according to BLM's records. I have looked at our well listings and all wells are listed as P&A which is only correct for East Teshekpuk #1 which was properly abandoned including removal of the diesel this past winter season. I recommend that the current status of the remaining wells be changed._to OBSW,_pending ina proper P&A by BLM., This recommendation is similar to what was done with E Tesh and _Lupine Unit#1 when it was determined that the wells were actually not P&A. If you are in agreement, I will forward a cop~of this messay~e ,to Bob Fleckenstein so the changes can ~e ... made in RBDMS. I will make sure a copy of that message is sent to each welt file.

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

The final surface reclamation of the surface and pits will be done the following winter season. The well is currently Temporarily Abandoned with a 2,255' PBTD and is being utilized by the USGS in their permafrost temperature monitoring program. There were 20 USGS monitoring wells in the program. The BLM plugged and abandoned the East Teshekpuk #1 well in 2008 and the Atigaru Point #1 will be the second of these monitoring wells that we will plug and abandon. Encroachment of the Arctic Ocean onto the wellsite has accelerated our need to perform this work before the well is taken over by the advancing wave action on the coast. Some of the well pad area has been eroded already. I have included the wellbore history of the drilling, casing, and cementing status of this well with the proposed wellbore status after final plug and abandonment operations. The wellbore is currently in a TA status with cement plugs from 11,535' TD to the 2,255' PBTD. The 13-3/8" surface casing was cemented to surface from 2,509' KB and there is no Arctic Pack present in the 13-3/8" x 9-5/8" casing annulus. The 9-5/8" intermediate casing was cemented for 8,147' KB set depth back up into the 13-3/8" surface casing to 2,370' TOC and the 9-5/8" casing was cut off and removed from this depth to the surface. The wellbore was temporarily abandoned with 2,155 feet of diesel fuel left in the wellbore. Our final abandonment of this well will include the removal of the diesel fuel from surface to 2,155 feet and replaced with NaCl water then a cement plug will be placed on top of a mechanical plug from a minimum of 200 feet below MSL to surface and all casing strings will be cut off below the mean water level for future navigational concerns. (See attached file: Estimated Wellbore Diagram Altigaru #l.x1s) Are there any concerns or recommendations that the AOGCC would have with our proposed well abandonment procedure that are required by the AOGCC? Please provide your comments, if you would. The BLM wants to be sure • We address any issues that the AOGCC may have on the final plug and abandonment of the Atigaru Point #1 well. The BLM will provide the AOGCC with an Application for Sundry Approvals (Form 10-403) in duplicate for your approval prior to initiating this proposed work. Thank you. Thomas Zelenka, P. E.

Messrs. Allen and Devine January 13. 1995 BLM/USGS Inactive Drilling Waste Disposal Facility Closure Approval The Review Procedure The qualitative risk scre~ning procedure required in the above referenced document determines whether a site presents negligible levels of risk. or if it is a significant risk generator. A decision scheme is then empioyed to establish (1) whether or not there is a basis of concern. and (2) whether or not a waste site is likely to present signirïcant risk to human or environrnentai receptors.

A decision scheme is then employed to establish ( 1) whether or not there is a basis of concern. and (2) whether or not a \vaste site is likely to present signiricant risk to human or environmental receptOrs. The rirst Step in this screening criteria is establishing a basis of conc~rn: "If the waste site has released contaminants or there :lre mechanism for potential releases and [here :lre receptors nearby. then. there may be cause for concern. and the waste site should ce srudied further.'

The criteria that :Ire measured :u :l waste site to satisfy the above logical arguments are: E'/idence of release of chemic:1l comaminarion at the '.vasre site in excess of Alaska Water Quality Standards for one or more target compounds. or yfechanism for potential release. and Proximity of the waste site to biological receptors.

The second step detennines 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."

GEOLOGIC SUMMARY INTRODUCTION The Atigaru Point No. 1 is located in the NE 1/4 of protracted Section 19, T14N, R2E, Umiat Meridian (see Figures 1 and 2). The surveyor's plat located the well 1422' FN Land 1925' FEL of the section. The location is on the tip of Atigaru Point, which projects out into Harrison Bay, and is located approximately 80 miles west-northwest of the Prudhoe Bay Field and approximately 23 miles southeast of the U. S. Navy, Cape Halkett No. 1 well. The Atigaru Point No. 1 was drilled in 1977 just prior to the relinquishment by the Navy of the Naval Petroleum Reserve No. 4 (now designated the National Petroleum Reserve in Alaska). PRE-DRILLING PROGNOSIS The Atigaru Point No. 1 was drilled on a location that was as far to the northeast as it was feasible to locate in order to maximize the possibility of approaching the updip erosional truncation of both the Sadlerochit Group sandstones and the Lisburne Group carbonates. By locating on the tip of Atigaru Point, it was hoped that the well would encounter the favorable Sadlerochit and Lisburne porosity which had been found in the Cape Halkett No. 1 well, and which, of course, exists in the Prudhoe Bay Field. This favorable porosity development appears to be related to the proximity to the erosional truncation. The secondary objectives of the well were sandstones at or near the basal Cretaceous unconformity (Kuparuk Formation equivalent) and the Sag River Sandstone. POST-DRILLING ANALYSIS Favorable porosity development, which had been anticipated in both the Sadlerochit Group sandstones and in the Lisburne Group carbonates, was not present at the Atigaru Point No.1. The sandstones of the Sadlerochit Group contained a large amount of white clay filling in the matrix, which greatly inhibited their porosity. A core (Core No. 1) was taken in the Ivishak Formation from 8712-8742'. The porosities varied from a low of 1.1% to a high of 14.2%. The average for the 30-foot interval was about 10%. Shows in the sandstone were scattered, very spotty and yielded generally poor cuts. The carbonates of the Lisburne Group also exhibited very poor porosities. The average was generally in the 1% range. No visible shows were noted in the Lisburne. The Sag River Sandstone had fair porosity (20%), but calculated to be 100% water satu rated. Sandstones of the Kuparu k Formation were not developed at this location. 1 ¡~~ ~ P!!..., J. f\ + ~g ";...~ .. , '"7505 N·;I:':........HO', j SMITH BAY 17~' 'fI--~ ------------------- 4 + + <" ðN . unò'one i K OOkÞu. . 10,192 .r""""..~ Camp JJ W Dolt"" No I Lonel.Y..

WELLSITE GEOLOGIST'S REPORT BY: W. D. FENEX EDITED BY: GORDON W. LEGG SUMMARY The Atigaru Point No. 1 was drilled to test the entire stratigraphic section above the argillite basement on a seismic structural closure located on the southwest flan k of the Barrow Arch. This structu re is on trend with the larger "Eskimo Island" structure to the northwest and offshore within Harrison Bay. The area of closure and the vertical relief, as mapped seismically on the top of the Sadlerochit Group, are about 4,145 acres, and 75', respectively. At the Lisburne level, closure and vertical relief are about 3,480 acres, and 150'. Although the well was structu rally low to the seismic estimates (as much as 300' at the Lisburne level), there is no reason to believe that structural clos u re does not ex i st at the location. The Ivishak Formation contained some traces of scattered, very poor show near the top, but the very poor porosity observed in the samples, and confirmed by log analysis (10-12%), would have precluded the possibility of a productive reservoi r. The Lisbu rne carbonates did not have any shows in the samples, and the Lisburne, also, had such low observed and calculated porosities (generally less than 1%), that it could not be considered as a potential reservoir at the drilled location. The Sag River Sandstone, which had fair to good porosity (up to 20%), was 100% water satu rated. Scattered oil shows were encountered in sandstones of the Nanushuk Group and in sandstones of the Torok Formation. All of these sandstones were thin, shaly, and very tight. No zones encountered in drilling the Atigaru Point No. 1 were considered to be worthy of fu rther evaluation. STRATIGRAPHY There were no samples caught from the surface down to a depth of 545'. CRET ACEOUS- TERTIARY (undifferentiated) 545-980' The section from 545' to 980' is composed predominantly of gravel which contains large, subrounded fragments of quartz, chert, and unidentified metamorphic pebbles. The gravel is interbedded with thin beds of clay, which is soft and gummy. The percentage of clay increases toward the bottom of the interval along with occasional interbedded sandstones, which are gray, very silty, argillaceous, very fine to fine grained, and are poorly sorted and relatively unconsolidated. 4 e . I I- I- I lè I- I I I I I I I I I I I I I CRETACEOUS Senonian 980-2630' The dominant lithology in this interval is clay, which is gray-brown, bentonitic, slightly silty in part, and soft and gummy. The apparent clay seen in the samples is probably poorly compacted claystone. Interbedded with the claystone are thin sandstone beds, which are gray, argillaceous, very fine grained to silty, poorly consolidated, and containing numerous thin seams of lignite. Below 1815', the clay becomes predominantly claystone, much like the clay above, but better consolidated and typically micaceous. The sandstones interbedded with the claystones are light gray and white to light gray-green, frequently "salt and pepper", with carbonaceous material and white clay. The sandstones are mostly fine to medium grained, calcareous, micaceous, and exhibit very poor visible porosity. Lignite is common in thin beds from 2300-2430'. Cenomanian to Turonian 2630-3410' This interval consists of thin sandstones interbedded with siltstones and claystones. The claystones predominate. These rocks are similar to the zone above, but contain no lignite and probably represent somewhat more marine conditions, as evidenced by the occasional presence of glauconite. Nanushuk Group: 3410-5520' The upper portion of this interval, down to approximately 4400', is quite sandy. The sandstones are gray, "salt and pepper" in appearance, and very fine grained to silty. A few beds are medium and coarse grained. The sandstones are typically micaceous and frequently glauconitic, and contain carbonaceous laminations and white clay filling; some are slightly dolomitic. All the sandstones have nil to very poor porosities. Interbedded with the sandstones are siltstones, which are light gray, argillaceous, micaceous, pyritic, carbonaceous, and frequently fossiliferous, and shale, which is gray-brown, fissile to subfissile, silty, pyritic, micaceous, carbonaceous, and grading in part to claystone. The remainder of the section (4420-5520') is predominantly shale with thinly interbedded siltstones and sandstones. Most of the rocks are micaceous and carbonaceous and contain thin beds of lignite coal from 5060-5090' and 5300-5350' . Torok Formation: 5520-7275' The Torok Formation is composed predominantly of shale, which is gray, typically silty, and frequently micaceous. The section grades downward to a darker gray, becoming nearly brown or black toward the base of the interval. There are frequent interbedded sandstones and siltstones scattered th roughout the Torok Formation, but the sandstones generally do not exceed 20' in thickness, and are invariably shaly, exhibiting poor porosity. These sandstones are gray, fine grained, "salt and pepper", glauconitic, and micaceous. The sandstones exhibit mostly poor visible porosity, which is la rgely choked by clay. Below a depth of 6480' and 5 :~ I I I I I I I I I I I I I I I I I I I .. . continuing down to the contact with the Neocomian ("Pebble Shale") at 7275', were scattered oil shows in a number of tight shaly sandstones. "Pebble Shale": 7275-7317' A thin sequence identified as Late Jurassic to Neocomian by Anderson, Warren & Associates, Inc., is probably an equivalent of the "Pebble Shale". The electric-log interval is from 7275' to 7317', while the paleo interval is chosen from 7282' to 7340'. The base of the unit is picked on the electric log at the bottom of a thin sandstone, which is probably a remnant of the basal Cretaceous unconformity sandstone. The lithology is primarily a brown, smooth to splintery shale. Significantly, the shale did not contain any of the frosted and polished, rounded, "floating" quartz grains, which are characteristic of the "Pebble Shale". JURASSIC Kingak Formation: 7317-8190' The Kingak Formation is present in the interval 7317-8190' (chosen as 7340' to 8310' by Anderson, Warren & Associates, Inc.). The lithology is predominantly shale that is brown, smooth, splintery, soft to fi rm. There are thin interbedded siltstones, which are brown, very argillaceous, "salt and pepper", glauconitic, and micaceous. The siltstones grade, in part, to silty sandstone, which contains abundant white clay in the matrix. Slightly over-pressured conditions were encountered throughout the interval during drilling operations. TRIASSIC Sag River Sandstone: 8190-8348' The interval 8190-8348' is chosen from the electric logs as representing the Sag River Sandstone. Actually, the interval from 8190' to 8250' is a silty shale and siltstone, but is very hard and brittle. The zone is quite resistive on electric logs, differentiating it from shale of the Kingak Formation. This resistive zone is generally classified as a transitional facie.s from the Kingak Formation to Sag River Sandstone. The Sag River Sandstone was one of the objective formations in the Atigaru Point No.1. The sandstone body, encountered from 8250' to 8348' is white, very fine to medium grained, well sorted, subangular to subrounded, soft, friable, slightly dolomitic, and generally choked with white clay matrix. The sandstone contains approximately 10% bright green glauconite, has very poor to poor visible porosity, and has scattered fragments which exhibit dull gold fluorescence. Shublik Formation: 8348-8595' The Shublik Formation is composed primarily of resistive carbonates. The lithology is principally calcilutite, which is cream to tan, mottled brown, 6 · .. I- I- I- I I" I- I I I I I I I I I I I I I chal ky, cryptocrystalline to medium crystalline, and soft. Coarse black phosphate pellets are common. Some shell fragments are often present. Glauconite is rare, and some beds are silty. Thin shales are interbedded with the calcilutite. These shales are dark brown, blocky, silty, very calcareous, grading to limestone, and generally contain finely disseminated mica. PERMIAN-TRIASSIC Sadlerochit Group: 8595-9494' Ivishak Formation: 8595-9412' The Ivishak Formation (sandstone) was present in the interval 8595-9242'. The sandstone facies actually begins at 8605', with a 10' shale interval, which is much less resistive than the Shublik shales lying above the sandstone. This shale has been assigned to the Ivishak Formation. The interval from 9242-9412' is represented by the Kavik Shale Member of the Ivishak Formation. The Ivishak is mainly sandstone, which is light gray, very fine grained, minutely "salt and pepper", fair to well sorted, and is subangular to subrounded. The cementing material is mostly silica and white clay. There is rare glauconite and interstitial pyrite, and occasional carbonaceous material. The observed porosity is very poor, and scattered, dull gold fluorescence, yielding a very weak crushed cut, was observed at 8670'. From 8670' to 8712', scattered fragments yielded a rare, slow, streaming cut. A core was taken in the interval 8712' to 8742', and 30' were recovered (see description in Appendix B). Porosities in the core were generally 10% or less, and only scattered dull gold fluorescence, yielding very weak cuts, was noted. The formation includes scattered thin interbedded shales, which are brick-red, smooth to slightly silty, slightly fissile in part, and very finely micaceous. Also encountered from 8855' to 8925', are some gray to black shales, which are fissile, splintery, silty in part, and very finely micaceous. I n the interval from 8925' to 9050', the sandstones are medium to coarse grained, poorly sorted, and contain some coarse gray and white chert pebbles. The rest of the Ivishak sandstone (9050-9242') is much as above, but interbedded shales are more common. Kavik Shale Member: 9242-9412' The lower 170' of the Ivishak Formation is composed of shale, which is the Kavi k Shale Member. The shale is medi um to dark gray, blocky, with finely disseminated mica. Generally, the Kavik is silty and firm, but it is less silty and has a smoother appearance in the lower part. Occasional thin siltstones are interbedded with the shale. The siltstones are medium gray, micaceous, blocky, hard, brittle, contained some carbonaceous laminations, and frequently had some medium grained black specks along laminae. 7 :~ I I I I I I I I I I I I I I I I I I (e . Echooka Formation: 9412-9494' The lowermost part of the Sadlerochit Group consists of sandstone of the Echooka Formation. This sandstone is tan and speckled bright green with 10% to 15% glauconite. The sandstone is very fine to fine grained, subangular to subrounded, and contains abundant euhedral quartz crystals and some fine grained black chert grains. There is no observable porosity. Some dolomite rhombs were noted along fracture planes. No visible oil staining or fluorescence was observed in the Echooka Formation, but 2,400 units of gas were recorded from 9411' to 9425'. EARLY MISSISSI PPIAN-PERMIAN lisbu rne Group: 9494-10,890' Another primary objective of the Atigaru Point No. 1 was the carbonates of the lisburne Group. The upper part of the lisburne from 9494' to 9746' consists of calcilutitic limestone that is tan to buff, mottled, very fine to microcrystalline, and with finely disseminated pyrite. The limestone is stylolitic, chalky in part, hard and dense. The rock has no visible porosity and no shows. There is occasional chert and some bright green glauconite. Some oolites were noted. From 9746' to 9798', the lithology is predominantly shale, which is variegated red (lateritic), bright green, and light gray. The shale is fissile to smooth, occasionally finely micaceous and firm. Some shale is silty in part and grades to siltstone. From 9798' to 10,310', the lithology is predominantly calcilutite, with some oolitic, calcarenitic calcilutite. The calcilutite is buff to brown, mottled, very glauconitic, chalky in part, hard, brittle, with spar calcite cement and nil visible porosity or show. I nterbedded with the calcilutite are thin shales. These shales are variegated red, green, and gray. The interval from 10,310' to 10,623' is essentially oocalcarenitic calcilutite, as above, with cream to brown calcilutite, and with thin variegated shale, as above. This part of the lisburne includes some thin sandstones that are red to pink, very calcareous, argillaceous, medium to occasionally coarse grained, subangular to subrounded, very hard and brittle, and with no visible porosity or show. Dolomite is present in the interval from 10,623' to 10,750'. The dolomite is buff to cream, cryptocrystalline to microcrystalline to very fine crystalline, generally hard and dense, and cherty. Some of the dolomite is sucrosic in part with some pinpoint vuggy porosity, but no show. I nterbedded with the dolomite are variegated shales, as above, and sandstone that is buff to cream, "salt and pepper", fine to medium grained, with buff dolomitic cement. The sandstone is hard and brittle, glauconitic, and has no visible porosity or show. 8 . . I 1- I~ I I~ I I I I I I I I I I I I I I Anderson, Warren & Associates, Inc. reports the interval from 10,750' to 10,850' as being still in the Lisburne Group. Log correlations indicate the base of the Lisburne Group occurs at 10,890'. Originally, the wellsite geologist had assigned a "Kayak Shale" designation to this interval. The lithology is primarily red and pink sandstones, as above, with thin variegated shales, as above, and with some dolomites and calcilutites. Rocks of this interval appeared to be much more sandy than that above. Endicott Group: 10,890-11,328' The Endicott Group is represented in Atigaru Point No. 1 by a sequence of sandstones, shales, conglomerates, and limestones. The sandstones, shales and conglomerates are frequently pink and red, but also range to grays and greens. The variegated colors hint at a subaerial origin; however, the presence of limestones and coal beds in the interval 11,120-11 ,200' is marginal marine to marine. INDETERMINATE Argillite: 11,328-11,535' Rocks encountered within this interval and collectively called "argillite" range from the typical black, shiny, siliceous, micaceous, pyritic low-grade metamorphosed shales having a submetallic luster to quartzitic sandstones and variegated shales. These rocks were not immediately recognized as argillites by the wellsite geologist because of their non-typical natu reo OIL AND GAS SHOWS Fair shows of oil were observed in scattered sandstones of the Nanushuk Group of Early-late Cretaceous age. The intervals with shows from 3755' to 3773' and 3781' to 3795' were composed of sandstone, very fine grained to silty, soft, friable, finely disseminated mica, but with generally poor porosity and permeability. There was good even staining, dull gold fluorescence and a streaming cut. Only slight increases in mud logger gas shows were noted th rough these intervals. From 3985' to 4011', very thin sands interbedded with gray shale carried mud logger gas shows. From 4045' to 4058', oil shows were observed in sandstone, which was gray, fine grained to silty, micaceous, glauconitic, very poorly sorted, and with generally very poor porosity and permeability due to white clay filling. There were some poor, scattered shows in several sandstones from 6478' to 6725', which were very thin, and interbedded with dark gray, fissile shale. These sandstones exhibited dull gold fluorescence and a slow milky cut. These sands were generally gray, fine grained, soft, friable, micaceous, glauconitic, and with fair to poor sorting. Occasional medium to coarse grains were observed. Porosity and permeability were generally very poor because of white clay filling. These poor shows were in the middle portion of the Torok Formation. 9 ~ I I I I I I I I I I I I I I I I I I I e . Several argillaceous sands in the lower portion of the Torok carried scattered oil staining, with dull to occasional bright gold fluorescence, and fair to moderate streaming cut. Porosity and permeability in these sands is generally very poor. One sandstone (6948-6964') did exhibit bright gold fluorescence and slow, streaming cut. The sandstone, however, had very poor observed porosity. A very poor show was noted in the zone from 8655' to 8712' (Ivishak Formation). The show consisted of scattered, dull gold fluorescence, and rare, slow, streaming cut in a sandstone, which was fine grained to medium grained, dolomitic cement, moderately soft and friable, containing interstitial pyrite, and having very poor to nil visible porosity. No visible oil staining or fluorescence was noted in the Echooka Formation, but as much as 2,400 units of gas were recorded in the top of the formation from 9411' to 9425'. lithology consists of tan sandstone, with about 10% to 15% bright green glauconite, very fine to fine grained, and with very poor to nil porosity due to argillaceous content. CONCLUSIONS The Atigaru Point No. 1 was completely evaluated on the basis of sample analysis and log interpretation. The primary objectives of the well, both sandstones of the Sadlerochit Group and carbonates of the lisburne Group, had insufficient porosity development to provide adequate potential reservoir rocks. No other zones penetrated by the well had adequate thickness or porosity to be seriously considered to have potential as a possible reservoir. 10 I I I I I I I I I I I I I I I I I I I e .

Legg: Final log runs at Atigaru Point #1 were run on March 10 and March 13, 1977 and included Dual-Induction, Sonic, Neutronl Density, Dipmeter and sidewall cores. All the logs were def- inite¡Y sub-standard; the 2"/100' inductioc was run on a linear rather than a Jogarithmic scale and the spontaneous potential was useless, the Density was ~four times, not one of which is correct and no two of which repeat, the dipmeter was of very poor quality with numerous "dead" correlation curves and the core guns were plagued with numerous misfires. I I I The Sag River sand was topped at 8253 feet and exhibits an average porosity from neutron and sonic of 20% and is 100% water- bearing, the water calculating to be about 18,000-20,000 ppm r,.hich compares favorab¡Y with other wells in the area. Porosity in the Shublik averages 6-8% and cross-plots indicate a sand and lime- stone matrix, while in the Sadlerochit porosities were in the 10-12% range. The Echooka porosity appears to be about 14% and neutron-sonic cross-plots indicate about 75% limestone. In the Lisburne porosity is ver.y low (1% and less) and cross-plots 100% limestone. Argillite porosity is in the neighborhood of 10% and cross-plots shale. No evidence of hydrocarbon accumulation could be found. I I I Thank you for the opportunity of serving you.

I INTRODUCTION I The Atigaru Point No. 1 well is located in Zone A of Naval Petroleum Reserve No.4, North Slope, Alaska. The well is 1422 feet from the north line and 1926 feet from the east line of Section 19, Township 14 North, Range 2 East, Umiat Meridian. Drilling related operations commenced with rig up on December 31, 1976, and terminated on March 29, 1977. I I The well was drilled to a total depth of 11,535'. The primary objectives of the well were the Kuparuk River Sandstone, the Sadlerochit Group, and the Lisburne Group, with secondary interests in the Sag River Sandstone and the basal Torok Sand. At the conclusion of the drilling and evalu- ation operations, the well was left in a temporarily abandoned condition with cement and mechanical plugs set at selected intervals. I Husky Oil NPR Operations, Inc., supervised and directed the drilling and support operations as prime contractor for the Navy. Parco, Inc., was the drilling contractor; and Parco Rig 95, a National 130, was the dril- ling rig used. I I I I I I I I I I I I I i I I I I I I I . . DISCUSSION Field operations at the Atigaru Point No. 1 location commenced on December 2, 1976, with the mobilization of construction crews and equipment required to build the drilling pad and ice airstrip to accommodate C-130 Hercules aircraft. Construction work was completed on December 31, 1976, and the crews and equipment moved to another location. Rig move-in operations began on December 17, 1977. The rig, Parco 95, had previously been used by Mobil Oil in the vicinity of Prudhoe aay/Deadhorse. The rig move was conducted using Hercules aircraft and completed in eléven days with a total of 99 loads. Rig UP operations began on December 31, 1976. Rig up was completed in 13 days and the well spudded on January 12, 1977, at 4:00 p.m. Weather during rig move and rig up was generally good with the exception of two days of winds from 30 to 40 knots, with blowing snow. I I I I I I I I I I I I During rig up, a 30" conductor had been set at 99' and cemented with Perma- frost cement. A 17 1/2" pilot hole was drilled out below the 30" to 429'. The hole was opened to 26" to 429', and 26" hole was drilled to 525'. Problems with sloughing hole from 430' to 525' were encountered due to excessive gravels being drilled. Mud was mixed with sufficient viscosity to handle gravel. During this period, á ground blizzard occurred which severely hampered the water haul. After conditioning the hole, 20" deep conductor was run and set at 447'. The 20" was cemented to surface with 2600 sacks of Permafrost cement with full returns. A 20" casing head and 20" annular BOP and diverter lines were installed on the 20" deep conductor. The 20" casing shoe was drilled out with a 17 1/2" bit. Drilling was suspended pending weather improvements for cement haul to the location. A 17 1/2" hole was drilled from the shoe of the 20" to 2510'. The hole was logged from 2520' (logger's T.D.) to 447'. Three attempts were required to get the tools to bottom. The logs run were the Dual Induction Laterolog and the BHC Sonic Gamma Ray log. After logging, 13 3/8" surface casing was run to 2509' and cemented back to surface with 3925 sacks of Permafrost cement with full returns. A 13 5/8", 5000 psi BOP stack (SRRA arrangement) was installed on the 13 5/8" split unihead. A 5000 psi choke manifold and kill line were also installed. The 13 3/8" casing was tested to 2500 psi and drilled out with a 12 1/4" bit. The formation below the shoe was tested to a 0.64 psi/ft gradient. A 12 1/4" hole was drilled from 2509' to 8150' and logged from 8147' (logger's T.D.) to the shoe of the 13 3/8" casing. The logging program consisted of a Dual Induction latero10g, BHC Sonic/Gamma Ray, Compensated Formation Density/Compensated Neutron/Gamma Ray log, and a High Resolution Dipmeter. Ninety sidewall cores were attempted and 66 recovered. Intermediate 9 5/8" casing was run and landed at 8147'. Two FO cementers were run in the string and landed at 2352' and 2191' for use if Arctic Pack procedures became necessary. The 9 5/8" casing was cemented with 1000 sacks of Class "G" cement containing friction reducer and retarder. The plug was bumped with 3000 psi. it I I I I I I I I I I I I I I I I I I I . . BOP equipment was tested and the casing tested to 3000 psi. The 9 5/8" casing was drilled out with an 8 1/2" bit and the formation below the shoe was tested to Ii 0.61 psi/ft gradient. An 8 1/211 hole was drilled from 8147' to 8712'. Core No.1 was cut from 8712' to 8742' with full recovery. Drilling continued from 8742' to 9123'. Approximately 200 barrels of mud were lost while drilling. Drilling continued to 10,041'withno further mud lOBS. While drilling to 10,262', approximately 150 barrels of mud was lost through seepage. Drilling continued to 10,731' with an additional seepage loss of 70 barrels. After testing BOPE, drilling continued to 11,514'. The 8 1/2" hole was logged from 11,520' (logger's T.D.) to the shoe of the 9 S/8" casing with the Dual tnduction tðterolog, BHC Sonic/ Gamma Ray log, Compensated Formðtion Density/Compensðted Neutron/Gammð Ray log, High Resolution Dipmeter and Velocity Survey. After 10g8ing, the hole was cleaned out to 11,520'. Core No.2 was cut from 11,520' to 11,535', reocvering 13'. Due to a short in the electric line, it was necessary to relog the DIt, FDC/CNt/GR. Sixty-nine sidewall cores were attempted. Thirty-eight were misfires, 11 were recovered empty, one cup was lost, and 13 cores were recovered, for 19% recovery. 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 practicðl purposes, "straight." In the 17 1/2" hole, the maximum deviation was 3/40 at 2490'. In the 12 1/4" hole, the maximum deviation of 1 1/40, occurred at 5124' and hðd reduced to 3/40 by the casing point. After casing in the 8 1/2" hole, the deviation increased graduðlly to 2° at 9406', decreased to 1 1/40 at 10,041', and increased again to 20 at 10,422°. The deviation decreased to 1 1/40 at 10,769'and increased again to 20 at 10,953'. At T.D. the deviation had decreased to 10. At the conclusion of the log evaluation, cement plugs were placed across selected intervals in the 8 1/2" hole as follows: Plug No. 1 ftom 9460' to 9260' with 115 sacks Class "G", Plug No. 2 from 8650' to 8450' with 95 sacks Class "G" covering the 9 5/8" casing shoe. Plug No. 4 consisted of a retainer set at 7900' with 25 sacks Class "G" spotted on top. , The 9 5/8" casing was cut at 2370', recovering both FO cementers. Plug No.5 was set in the 13 3/8" casing from 2355' to 2255' with 100 SAcks of Class "G". At 2155', the well was reversed from mud to water to diesel to allow the well to be used in the U.S.G.S. North Slope geothermal measurement program. The abandonment well marker was installed, and the rotary rig released March 18, 1977, at 6:00 a.m. The rig was rigged down and demobilized to the South Harrison Bay location, which had been prepared as a storage location for the rig. The rig was stacked out for the summer. Detailed drilling information in the form of bit records, mud summary, time analysis, and casing and cementing reports, as well as geologic descriptions, is included in the body of the report. iii I . .

Navy-Atigaru Point No. 1 well is located in the National Petroleum Reserve in Alaska, formerly the Naval Petroleum Reserve No. 4 (Figure 1). The well is 1,422 feet from the north line and 1,926 feet from the east line of protracted Section 19, Township 14 North, Range 2 East, Umiat Meridian (Latitude: 70°33'22.03" North; Longitude: 151 °43'01.85" West). Alaska State Plane Coordinates are: X = 290,644 and Y = 6,055,988, Zone 4. Elevations are: Kelly Bushing 27', Ground 7'. Drilling related operations commenced with rig-up on December 30, 1976, and the rig was released March 18, 1977. The well was drilled to a total depth of 11,535 feet. The primary objectives of the well were the Kuparuk Sandstone, and the Sadlerochit and Lisburne Groups, with secondary interests in the Sag River Sandstone and the basal Torok sands. 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 Navy. Parco, Inc. was the drilling contractor; Parco Rig 95, a National 130, was used to drill the well. .ARAOW.~'-\ 81:4(/ ~~... "'0,., " Þ.

DRILLING SUMMARY Field oper~tions at the Atigaru Point No. 1 location started on December 2, 1976, with the mobilization of construction crews and equipment required to build the drilling pad and ice airstrip to accommodate C-130 Hercules aircraft. Construction work was completed on December 31, 1976, and the crews and equipment moved to another location. . Rig move-in operations began on December 18, 1976. The rig, Parco 95, had previously been used in the vicinity of Prudhoe Bay. The rig move was conducted using Hercules aircraft and completed in 11 days with a total of 99 loads. Rig-up operations began on December 30, 1976. Rig-up was completed in 14 days and the well spudded on January 12, 1977, at 4:00 p.m. Weather during rig move and rig-up was generally good with the exception of two days of winds from 30 to 40 knots with blowing snow. During rig-up, a 30" conductor had been set at 99' and cemented with Permafrost II cement. A 17-1/2" pilot hole was drilled out below the 30" to 429'. The hole was opened to 26" to 429', and 26" hole was drilled to 525'. Problems with sloughing hole from 430' to 525' were encountered due to gravels being drilled. The mud was mixed with sufficient viscosity to handle gravel and the hole then drilled to 545'. During this period, a ground blizzard occurred which severely hampered the water haul. After conditioning the hole, 20" deep conductor was run and set at 447'. The 20" was cemented to surface with 2,600 sacks of Permafrost II cement with full returns. A 20" casing head and 20" annular blowout preventer and diverter lines were installed on the 20" deep conductor. The 20" casing shoe was drilled out with a 17-1/2" bit. DriUing was suspended pending weather improvements for cement haul to the location. A 17-1/2" hole was drilled from the shoe of the 20" to 2520'. The hole was logged from 2520' (logger's total depth) to 447'. Three attempts were required to get the tools to bottom. The logs run were the DIL/SP and the BHC-Sonic/GR log. After logging, 13-3/8" surface casing was run to 2509' and cemented back to surface with 3,925 sacks of Permafrost I J cement with full returns. A 13-5/8", 5,000 psi blowout-preventer stack (SRRA arrangement) was installed on the 13-5/8" split unihead. The 5,000 psi choke manifold and kill line were also installed. The 13-3/8" casing was tested to 2,500 psi and the shoe and 10' of formation drilled. The formation below the shoe was tested with 400 psi (0.64 psi/ft. gradient). A 12-1/4" hole was drilled from 2520' to 8150' and logged from 8147' (logger's total depth) to the shoe of the 13-3/8" casing. The logging program was as follows: DI L/SP; BHC-Sonic/GR; FDC/CNL/CAL/GR; HDT -Dipmeter. Sidewall cores were shot. Intermediate 9-5/8" casing was run and landed at 8147'. Two FO cementers were run in the string and landed at 2352' and 2191' for use if Arctic Pack procedu res became necessary. The 9-5/8" casing was cemented with 1,000 sacks of Class "G" cement containing friction reducer and retarder. The plug was bumped with 3,000 psi. 2 . . I I I I I I I I I I I I I I I I I I I , . Blowout-preventer equipment was tested and the casing tested to 3,000 psi. The 9-5/8" casing shoe and 10' of formation were drilled out with an 8-1/2" bit and the formation below the shoe was tested to a 0.61 psi/ft. gradient. An 8-'1/2" hole was drilled from 8147' to 8712'. Core No. 1 was cut from 8712' .to 8742' with full recovery. Drilling continued from 8742' to 9123'. Approximately 200 barrels of mud were lost while drilling. Drilling continued to 10,041' with no further mud loss. While drilling to 10,262', approximately 150 barrels of mud were lost. Drilling continued to 10,731' with an additional loss of 70 barrels. After testing blowout-preventer equipment, drilling continued to 11,514'. The 8-1/2" hole was logged from 11 ,520' (logger's total depth) to the shoe of the 9-5/8" casing with the DI L/SP, BHC-Sonic/GR, FDC/CNL/CAL/GR, HDT-Dipmeter, and Velocity Survey. After logging, the hole was cleaned out to 11,520'. Core No.2 was cut from 11,520' to 11,535', recovering 13'. Due to failu re of Schlumberger equipment, it was necessary to relog the DIL/GR, FDC/CNl/CAL/GR. Sixty-nine sidewall cores were attempted. Thirty-eight were misfires, 17 were recovered empty, one cup was lost, and 13 cores were recovered. 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". In the 17-1/2" hole, the maximum deviation was 3/4° at 2490'. In the 12-1/4" hole, the maximum deviation of 1-1/4° occurred at 5124', and had reduced to 3/4° by the casing point. After casing in the 8-1/2" hole, the deviation increased gradually to 2° at 9406', decreased to 1-1/4° at 10,041', and increased again to 2° at 10,422'. The deviation decreased to 1-1/4° at 10,769' and increased again to 2° at 10,953'. At total depth, the deviation had decreased to 1°. At the conclusion of the log evaluation, a decision was made to plug and abandon the well. Cement plugs were placed across selected intervals in the 8-1/2" hole as follows: Plug No.1 from 9460' to 9260' with 115 sacks Class "G", Plug No. 2 from 8650' to 8450' with 95 sacks Class "G", Plug No.3 from 8350-8100' with 125 sacks Class "G" covering the 9-5/8" casing shoe. Plug No. 4 consisted of a retainer set at 7900' with 25 sacks Class "G" spotted on top. The 9-5/8" casing was cut at 2370', recovering both FO cementers. Plug No. 5 was set in the 13-3/8" casing from 2355' to 2255' with 100 sacks of Class "G". At 2155', the well was reversed from mud to water to diesel to allow the well to be used in the USGS North Slope geothermal measurement program. The abandonment well marker was installed, and the rotary rig released March 18, 1977, at 6:00 a.m. The rig was rigged down and demobilized to the South Harrison Bay location, which had been prepared as a storage location for the rig. The rig was stacked out 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. 3 I . .

INTRODUCTION After the 1976 drilling season, casing requirements were reviewed and design of casing strings standardized. Every effort was made to minimize weight and grade ch~nges for simplicity, cost effectiveness, and to reduce chances of error during handling and running operations. Casing sizes were selected to accommodate designs for wells from 2,000' to 20,000'. Steel grade selection was the controlling factor on design with low hardness (Rockwell C24-28) steel being selected for Arctic application and possible H2S environment. Below is listed casing sizes and design criteria required by Husky: SIZE(l) WEIGHT YIELD STRENGTH (PSI) MIN. MAX. MINIMUM PRESSURE REQU I REMENT (PSI) COLLAPSE BURST CONNECTION 20" 13-3/8,,(2) 9-5/8,,(3) 9-3/4,,(3) 7" 133#/ft. 55,000 80,000 1 , 500 72#/ft. 95,000 11 0, 000 3,450 53.5#/ft. 95,000 110,000 8,850 59.2#/ft. 95,000 11 0,000 9,750 38#/ft. 95,000 11 0, 000 12,600 3,050 5,350 7,900 8,540 9,200 STC BTC BTC BTC BTC (1) aD tolerance to be within API requirements unless adjustment absolutely necessary to meet ID requirements. Special drift to 12.25". Special drift to 8.50". (2) (3) The following are additional requirements primarily to assure that the steel exhibits the metallurgical properties for Arctic applications and resistance to hydrogen embrittlement. 1. All pipe that is 13-3/8" OD and smaller to be quenched and tempered. 2. Run Charpy "V" notch tests on two random samples per 50 tons per heat. Minimum acceptance of 15 ft.-lb.@-50oF. Furnish test reports with order. 3. Perform all testing normally required for API approved pipe. 4. Furnish test reports for ladle analysis, quantitative analysis, and all check tests as per API requirements. In addition, the following handling requirements were made: 1. Collars must be of same steel grade as pipe body. 2. Apply an API modified thread compound on mill-installed collar before bucking on. 31 . e I I I I I I I I I I I I I I I I I I I . 3. Inspect at mill uSing Tuboscope's Amalog IV or equivalent on 9-3/4" and smaller, and at least magnetic particle on 13-3/8" and 20". All pipe to have special and area inspection together with full length API drifting. (Note special drifting requirements.) 4. Apply Arctic grade grease on all connections before installing th read p rotecto rs . 5. I nstall closed-end type th read protectors. Plastic plugs can be used to secure wrench openings in protectors. 6. Buck up thread protectors with impact wrench. Both mill and third party inspection personnel should observe the installation of thread p rotecto rs . 7. Palletize or containerize the tubulars, if possible, prior to shipment from mill. Do not haul pipe like cordwood in gondola railroad cars. 8. All pipe to be Range 3. 9. No "V" notching or metal stenciling on pipe body or collars. Casing programmed for Atigaru Point No. 1 was as follows: 30" conductor at t80'; 20" at 500'; 13-3/8" at 2500'; 9-5/8" at 7800'; and a 7" liner to a total depth of 10,880' if needed for evaluation purposes. Actual casing run was 30" at 99', 20" at 447', 13-3/8" at 2509', 9-5/8" at 8147'. The 7" liner was not requi red. After total depth had been reached, the 9-5/8" casing was cut off at 2370' and recovered back to surface. The 13-3/8" annulus from 2155' to surface was left full of diesel. This was to allow future temperat'ure measurements by U. S. Geological Su rvey personnel. 32 I . I I I I CASING OR LINER CEMENT JOB .

Unit J-1. which contains the reservoir -Barrow sandstone" in the Barrow area. lies unconformably on TR-3 and is restricted to the northern part. of the NPRA. J-l is Early-Middle(?) Jurassic and coincides with foraminiferal zones F-17 and F-18 (Anderson. Warren. and Associates. 1974-1979). . The thickness i of J-1 is related to its truncation by the overlying mid-Jurassic and basal -Pebble Shale- unconformities. The thickest section penetrated is 1.038 ft (316 m) thick at East Teshekpuk 1. this section extends to the west and paralle1s the Barrow Arch. Northward. toward the Barrow High and the Barrow Arch. unit J-1 is progressively truncated by the basal ·Pebble Shale" unconformity. In the eastern half of the NPRA. the mid-Jurassic unconformity deeply truncates J-l toward the southeast; J-l thickness ranges from 580 ft (177 m) at Ikpikpuk Ito 136 ft· (42 m) .at North In i gok 1,; . ,.. -<,,- . .~. ~ > '( ) In the western half of the Reserve. trUncation by the båsal -Pebble Shale- unconformity' is more gradual. and 140 ft (43 m) of J-1 is present at Tuna1ik; 1.

The rocks are Late Triassic to Early Jurassic and are .restricted to the northern half of the Reserve. The Sag River Sandstone is a sheetlike sand body that probably consists of a series of overlapping bars. The lithology is typically light-greenish-gray glauconitic ca 1 careous sandstone. The Sag River Sandstone becomes increasingly silty toward the south and west. At Inigok 1 and Tunalik 1, laterally equivalent siltstone and shales are present. The Sag River Sandstone also grades into equivalent calcareous and glauconitic siltstones, shales, and silty sandstones on the Barrow High. ~ Porosity within the unit is very good in wells drilled on the Reserve. The lowest porosity, 7.3 percent, was at Ikpikpuk -li--1he_-bj.-g.h.e_s_t_pº-rQ~ltY:.t22_1)e !:.ce!'t, wasi n East_S1mpsonl. Porosities above 16 percent were recorded--fn-a-lrwEHTs--lntñën northwestern NPRA. A second area of good porosity de~e10pment is over the Fish Creek Platform northward to where the unit is truncated by the basal npebble Shale" un(onformity. There were several minor oil shows in the Sag River Sandstone at East Simpson 1 and East Simpson 2. ¡-1~~1 L- I + + HUNCH' SEA . I I 1". ·.'''1 I i , h.. ... + I....... ,_.- !

The truncation zone runs roughly east-west and is just north of J. W. Dalton 1 and W. T. Foran 1. West of Dease Inlet. the unit onlaps the Barrow High. Thicknesses of TR-3a at East Teshekpuk 1 and West Fish Creek 1 indicate thinning over the Fish Creek Platform. Thinning also is apparent on the flanks of the Meade Arch. as indicated at South Meade 1 and Kugrua 1. In the western half of the Reserve, the unit is thickest at Tunalik 1 and thins northeastward toward the Barrow High. Lithology and hi gh ganuna-ra,y curve deflections within TR-3a suggest that the thinning may be due to periodic nondeposition. The TR-3a unit consists of calcareous carbonaceous shales and siltstones, silty limestones, and silty calcareous sandstones. Glauconite is a conunon accessory mineral in the sandstones, and thi n shell beds occur throughout the interval. Sand-shale ratios and clastic ratios indicate that the best sand development is in the northwestern part of the Reserve. I High sand-shale ratios at Peard 1, Walakpa ·1, Walakpa 2, and Iko Bay 1 i ndi cate a source area northwest of the present shoreline. TR-3a is progressively more arg111aceous toward the southeast and more calcareous toward the south. Over the Fi sh Creek Pl at form J the amount of 1 imestone present increases significantly. At South Harrison Bay 1, the unit is mostly limestone. At Lisburne 1, with no nearby control, arenaceous limestone is indicated. Apparent lithologic anoma'li es occur at East 5i mpson 2 where the uni tis interbedded siltstone and limestone and Drew Point 1 where the high sand count may be caused by statistical variations, or may indi.cate a small barlike body flanking the Barrow High. -,..---~_._".---. ... - -----..-----. - ---.,----" - + + CHUKCHI SEA WAI, . + + SKUll " T BASED ON SEISMIC RPRETATION.
