Performed final plug and abandonment operations. Demobilized wellsite equipment on March 28, 2017. Work Objective The priorities of the attached Plug and Abandonment Procedure for Avak#1 are listed as follows: 1. Perform all work in a safe and efficient manner,without causing harm to people, environment, or equipment. 2. Safely secure the surface of the well so that accidental entry is impossible. Well History • The well was abandoned and a cmt plug set at 1,348' MD using 25 sacks High Early Cement (January 14, 1952). i. TOC in 9.625"OH, @ 1,248' MD. ii. 11.4 ppg drilling mud from TOC(1,248' MD)to 840' MD.Surface to 840'was vacated of fluid. • During April 2016 wellsite visit, noted the following: i. Ice plug was tagged at 30' MD using a plumb bomb. Fluid in wellbore (30'—840') MD is unknown. ii. 10%" riser was welded to top of casing(top 3'was left above GL). • Discovered a 30" casing string and found ice plug at 505' based on fluid fill during March 2017 P&A. Variance Bureau of Land Management (BLM) acknowledges that the Avak#1 does not meet the requirements of Onshore Oil and Gas Order No. 2 (Onshore Order No. 2). After performing the due-diligence and comparing the Scope of Work Schematics for Avak#1, it was revealed the P&A Sundry was deficient as follows: Avak#1 1. Csg Shoe is required to be overlapped with cement (43 CFR 3160 "Onshore Oil and Gas Order No. 2, Drilling Operations'; Section G,4). On December 22, 2016, Marsh Creek, LLC (Marsh Creek) and Petrotechnical Resources of Alaska (PRA) submitted a suggested scope change for Avak#1 to meet Onshore Order No. 2 (43 CFR 3160 "Onshore Oil and Gas Order No. 2, Drilling Operations", Section G, 4). On January 9, 2017,the BLM corresponded with Marsh Creek stating the BLM's recognition of the currently approved Sundry's not being compliant with Onshore Order No. 2. The change request to meet Federal regulations was denied due to "minimizing risk to safely achieve a solid surface plug."

It also assumed that thawing of the well bore was likely to be required. 49 bbls of brine were required to fill the casing, estimate top of the ice plug is 530'based on that volume. Attempted to pressure test the BOP's to 250 psi,the pressure is bleeding off slowly. No surface leaks were found,indicating the pressure loss is in the wellbore. The requirement to use a BOP was driven by the thawing operation. Since no thawing operations are needed the well control equipment requirement changes to a diverter and only a function test will be performed. We will still need to make a trip in the well to ensure it has no restrictions smaller than our cement platform.

We were unable to maintain the 500 psi due to a slow leak. The leak is suspected to be in the surface equipment. BLM and PRA agree we have a competent cement plug and the 30 min test is not necessary. There is no regulatory requirement to hold pressure for 30 minutes to test a surface cement plug. We will modify the procedure and pressure the well to 500 psi and blead off. Describe the Reason for the Change: Unable to hold pressure due to suspected slow surface leak.

The current configuration of this well was determined as accurately as possible with regard and interpretation to the available information relating to this well. Due to the nature of this well and its history there is a possibility of inaccuracies in the current well configuration. This Plug and Abandonment Procedure was designed based on interpretation of previous well history data.

Work Objective The priorities of the attached Plug and Abandonment Procedure for Avak#1 are listed as follows: 1. Perform all work in a safe and efficient manner, without causing harm to people,environment, or equipment. 2. Safely secure the surface of the well so that accidental entry is impossible. Variance Bureau of Land Management(BLM) acknowledges that the Avak#1 does not meet the requirements of Onshore Oil and Gas Order No. 2(Onshore Order No. 2). After performing the due-diligence and comparing the Scope of Work Schematics for Adak#1, it was revealed the P&A Sundry was deficient as follows: Avak#1 1. Csg Shoe is required to be overlapped with cement(43 CFR 3160"Onshore Oil and Gas Order No. 2, Drilling Operations",Section G,4). On December 22, 2016, Marsh Creek, LLC(Marsh Creek)and Petrotechnical Resources of Alaska(PRA) submitted a suggested scope change for Avak#1 to meet Onshore Order No. 2 (43 CFR 3160 "Onshore Oil and Gas Order No.2, Drilling Operations",Section G,4). On January 9, 2017,the BLM corresponded with Marsh Creek stating the BLM's recognition of the currently approved Sundry's not being compliant with Onshore Order No.2. The change request to meet Federal regulations was denied due to"minimizing risk to safely achieve a solid surface plug." Current Well Information • The well was abandoned and a cement plug was set at 1,348' MD using 25 sacks High Early Cement(January 14, 1952). • TOC, in 9.625"OH, @ 1,248' MD. • 11.4 ppg drilling mud from TOC(1,248' MD)to 840' MD. • Drilling mud was bailed out to 840' MD prior to abandonment and left void (Jan. 1952). • 200'thermistor cable was installed at time of abandonment. • During April 2016 wellsite visit: i. Ice plug was tagged at 30' MD using a plumb bomb. Fluid in wellbore (30'—840') MD is unknown. ii. Thermistor cable was not visible at surface. • 10 3/" riser was welded to top of casing(top 3'was left above GL). • Above ground ambiguities exists on csg. Will need to excavate and cut below csg integrity issues. Avak#1—Final Sundry Page 2 of 7 gker . 3 1414,4t44,:a.t Z.104164 Ate,IIIA '41:ARSHCREEK. Sundry Procedure Pre-Rig Ops: 1. Identify the surface location of the well and check the area for potential gas. 2. Remove general debris from cellar. Excavate around csg to obtain a desired working height. Remove wood and steel pilings obstructing the work area. 3. Stage tool&parts connexes, boiler,cement batch mixer,scaffolding,generators, heaters, circulating tanks and all other wellsite equipment. 4. Spot surface support equipment and 30 Ton National Cab Mounted Boom Truck. 5. Cut production csg below pipe structure ambiguities to desired height for circulating. 6. Weld Flange onto 10%"csg to accommodate 4 1/16" BOP Stack. Operations: 7. Nipple Up(NU)Blowout Preventer(BOP). Close blinds. Shell test BOPE against pre-existing ice plug to 250 psi(low) and 500 psi(high)for 30 minutes each. Manifold returns to open top tank(s). Bleed down to zero. Reference:Onshore Oil and Gas Order No.2,Drilling Operations/lll.Requirements/A. Well Control Requirements/2./i 8. Build 9.8 ppg NaCI brine. Preheat to 150°F. 9. Rig Up(RU)tbg handling equipment to run 1.9" Workstring(WS). 10. Pick Up(PU)/rabbit 1.9"WS with drift. Run in Hole(RIH)w/1.9"WS while circulating warm brine to 180' MD,or until refusal. Expect ice the entire duration as the base of the permafrost is reported at 1,330' MD. Refusal is defined as not being able to make further progress after 30 min. of circulating, indicating an impassable obstruction has been encountered. Communicate with the regulatory representative that cement will need to be set at a shallower depth. 11. Circulate warm brine until returns are consistent and have acceptable non-freezing properties, Pull Out of Hole(POOH). 12. Pick Up/Make Up(PU/MU)Junk Mill, bit sub. Crossover to WS. MU onto WS.

Pump/displace wellbore to surface with 15.7 ppg ArcticSetl cement out end of 1.9"WS. 16. Wait on Cement(WOC)for 6 hours to set up. RI w/WS,tag top of cement to verify cement plug has not fallen downhole. 17. Close blinds. Pressure test cement plug to 500 psi for 30 minutes. 18. Nipple Down(ND) BOP. Cut/remove SOW flange. 19. Excavate around the well to a minimum depth of 6' below ground level. Avak#1-Final Sundry Page 3 of 7 • ..) .1)/11 MI . 1)414014e14441/kA44144. M.ARSHCREFK 20. Cut Tubulars 5' below ground level. Make sure wellbore and all annuluses are full of cement to surface. 21. Weld on a marker plate that meets current BLM regulations. Ensure that the final marker post/plate is 5' BGL. 22. Backfill excavated hole and proceed with disposal of waste materials from the site. Mound the excavation with gravel or tundra organics to account for settling, 23. Remove any remaining wood or steel pilings and debris from the surface of the location and dispose of waste materials from site. 24. Return to site the following summer for stick pick operations.

OBJECTIVE 1. Perform all work without causing damage to the environment, harm to people or equipment. 2. Perform all work in a safe and efficient manner. 3. Perform the successful final abandonment of the legacy wellbores. WELL HISTORY This well drilled in 1951 and has an RKB of 17.3 ft.The well has been previously cut off at ground level and there is no existing wellhead.The well was abandoned by bailing out the fluid down below the permafrost.There is a thermistor cable installed in this well that should be visible at surface.

Identify surface location of the well and check the area for potential gas. 2. Excavate and pull approximately 6 steel piling adjacent to the well to a minimum of 5 feet BGL during the location preparation process. 3. Verify condition of surface casing string and top of ice(if possible)in the wellbore.The last fluid level was reported to be bailed to 840 feet so expect the 10' inch casing to be empty for several hundred feet.The base of permafrost is at approximately 1400 feet per the BLM Legacy Wells Report. 4. Move in required equipment,cement batch mixer,heaters,boiler,circulating tanks,piping,generators, scaffolding,tarps,and other well site equipment. 5. Records and photos indicate that the 10%inch casing sits 3 or 4 feet above ground level and has markings from bullet holes. 6. Excavate around the well and cut off 10%inch casing to the desired height for circulating.Weld a flange on the 10%inch casing and rig up BOP and circulating equipment to direct returns to open top tank. Remove thermistor cable if possible. sVACLLE.St 6OPE i SCO f3S1G 7. Fill the well with non-freezing_9=8 ppg kill weight NaCI brine. Run tubing in the well and circulate warm brine to melt any frozen fluids to a depth of 168 feet or until refusal. Refusal is defined as not being able, to make further progress after 30 minutes of circulating and working the pipe.In this case,notify BLM officials that an impassable bridge has been encountered and that cement will be set at a shallower depth than the target depth of 170 feet RKB. 8. Circulate warm brine until the returns are consistent and have acceptable non-freezing properties.Collect a sample for PCB lab analysis. 9. Line-up surface piping to take cement returns to an open top waste tank. 10. Set a viscous plug from 190 to 170 feet RKB if not in frozen material at 170 feet RKB. Mix and pump sufficient volume of Artic-Set cement to fill the wellbore from 168 feet RKB to the surface.Pull out of hole. i'/— t'S bbd CENal4T 11.

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.

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.

Wayne Svejnoha 2 July 11, 2013 The BLM plan to address these known, suspected, and unknown releases at legacy well sites is notably absent from the documents presented to date. The three primary regulatory agencies that need to be involved in the plan are ADEC —Contaminated Sites,Alaska Oil& Gas Conservation Commission, and ADEC —EH/Solid Waste. Other agencies will need to be consulted as well. Below we provide recommendations for a coordinated plan using the Uniform Federal Policy for Quality Assurance Project Plans (UFP-QAPP) that will involve all of the regulatory agencies in one coordinated manner. This will allow BLM to address these sites in a consistent and coordinated project which fulfills all of the regulatory requirements so that the sites do not need to be re-visited in the future when they are closed after this project. Attached are our comments on each specific well. The acronyms used on the list include terms that are typically used in a CERCLA type investigation however they are also suitable for investigations conducted under the State of Alaska cleanup rules. These include the following; Historical Records Review (HRR) This is recommended for almost all of the well sites. Much of the information required for these reviews is already contained in various reports and appendices or in BLM files. The Historical Records Review should document the type of releases that might have occurred from drilling operations as well as historical use of the site, and should capture all available information on the drilling fluids used and any product produced or released. Preliminary Assessment (PA) This is recommended for almost all of the well sites. A Preliminary Assessment is a limited scope investigation that provides an assessment of information about a site and its surrounding area to distinguish between sites that pose little or no threat to human health or the environment and sites that require further investigation. The PA is a CERCLA defined document and typically does not require sampling. Site Inspection (SI) If the PA recommends further investigation, then an SI is necessary. The SI is a CERCLA defined document, and it is analogous to an initial report of contamination under state cleanup rules. On some legacy well drillings sites it is evident now that an SI is required just from a review of the reports. An SI investigation typically includes the collection of samples to determine what contaminants are present at the site and whether they are being released into the environment. An approved site specific workplan is required under both CERCLA and 18 AAC 75 prior to SI sampling. The SI typically is not intended to develop a full site characterization,but is limited to determining the presence or absence of a release. If contamination is found after completion of the HRR,PA,and SI then a RI/FS under CERCLA, or a Site Characterization Report and cleanup plan under 18 AAC 75 is required. DEC recommends that BLM incorporate into the strategic plan the processes outlined in this letter. A team of agencies composed of AOGC,DEC-CS,EPA as required,and DEC-EH should address regulatory and technical requirements for these well closures. By cooperating and working together with the regulatory agencies BLM will save time and expense,and regulatory uncertainties will be avoided. The strategic plan should reference a project to prepare a generic workplan. DEC suggests that BLM utilize the generic UFP-QAPP workplan format for the required environmental work. If properly prepared,the workplan could encompass most of the investigations and cleanups required at these sites over multiple years. At other multi-site projects we have found this to be an effective way to reduce uncertainties and risk in these types of investigations. A very small site specific FSP could then be developed as BLM approaches each drilling site. Regulatory decisions made during workplan development would provide more certainty in the planning process for cleanups. _r•\c1AA\rc \ FPrirral AoP.sire\TMIT\FILM\Proiects\Legacy Wells\7 11 13 Letter to BLM on Legacy Wells.docx Wayne Svejnoha 3 July 11, 2013 Please review the attached list of specific sites. if you have any questions, please do not hesitate to call me at 907-451-2181 or by email at fred.vreeman @alaska.gov.

The Avak #1 well site is located along the Barrow Gas Field Road that connects Barrow with the East Barrow Gas Field [Figure 1]. This well is approximately 200 feet on the north side of the road, approximately 7 miles from Barrow. The last inspection of the Avak #1 well site was in July 2012. Site Description: The Avak #1 site consists of a well and its associated scattered surface remains in an area measuring 30 feet north to south by 50 feet east to west [Figure 2]. The U.S. Navy drilled the well in 1951. There is no pad or reserve pit associated with this well. The well has a cellar, consisting of a 10 feet by 10 feet wooden box. The inside of this box was excavated to a depth of about 10 inches. At the time of the last inspection, standing water and algae were present in the cellar. A total of 20 metal pilings are in the immediate area surrounding the well. These pilings extend from 6- to 24- inches above the ground surface, and at least 4 pilings have metal plates attached at the top to create a flat surface. The depth the pilings extend below ground is unknown, but they would need to be deep enough to support a working platform for drilling operations.. Approximately 35 feet north of the well are two pieces of rusted, corrugated metal sitting on the surface, which may be associated with the well [Figure 3]. Surface Risk Assessment: Low. Justification: This site has no known contaminants present on the site. The Avak #1 site area appears to be consistent with the surrounding vegetation and landscape, with no scars or other visible damage. The well site lies about 200 feet from a tributary of the Mayoeak River, and the river itself is less than 1/2 mile to the west. With the small amount of topographic relief in the area, the river is meandering with a very slight current. Neither the river nor its tributary pose any risk of erosion to the well or associated surface debris. Additionally, there does not appear to be any impact from the well site to the river. The BLM will need to prepare a determination of eligibility pursuant to Section 106 of the National Historic Preservation Act, due to the age of the site. If the site is not eligible, then the small amount of remaining surface debris should be removed as funding allows or in conjunction with other scheduled operations in the area, if possible. zm HEQ W\" 1 SCAR 16 BLM Open File Report 127 • February 2013 Legacy Wells Summary Report • Section 2: Wells BLM Monitors .- 4. a —104.0"— awr. . w / .

When completed, a plug was set at 1,348 feet using 25 sacks of High Early cement [Figure 5]. The well was drilled to test an anomaly identified by seismic surveys. These surveys showed a nearly circular area of no reflections and several faults that radiated outwards in several directions. The other objective was to learn more about the pre- Mesozoic rocks in the area (Collins and Brewer 1961). • Well Condition: Instead of a wellhead, the well consists of a casing that is open to the environment. This casing diameter is 10 % inches and total height is approximately 4 feet. Five bullet holes are present at the top of the casing, but do not completely penetrate the metal [Figure 4]. • Wellhead Components: There is no wellhead at this site. Geologic Setting: The Avak #1 test hole showed very complex subsurface geology with a slight oil show. The shows consisted of visible oil cuts in the Hue Shale and within the Lower Jurassic period Barrow sand. The well also penetrated the Gubik formation (Collins and Brewer 1961). Development Potential: Development occurred in this area for decades. Avak #1 has not had any detrimental impacts to the existing infrastructure or the development process. The oil show is below the existing plug. Groundwater Resource: None. Continuous permafrost is about 1400 feet thick throughout the entire Barrow region. Fresh water aquifers are not present. The town of Barrow does not get its drinking water from aquifers, but rather from treated surface water (Alaska Department of Environmental Conservation 2012). Other Information: There is no indication of hydrocarbon escapement at or near the Avak #1 well.

Spudded: May 17,1955. Completed: June 17, 1955. Gas well: maximum stabilized rate of flow, 7.9 million cubic feet per day, with no water. Total depth: 2,456 feet. In 1955, after the U.S. Navy had suspended explora- tory operations in Naval Petroleum Reserve No.4, a private const.ruction firm, Puget Sound and Drake, drilled South Barrow test well 5 for the U.S. Air Force installation at Barrow; the well is a standby well for South Barrow test well 4, replacing South Barrow test well 2 which had been abandoned. South Barrow test well 5 is between the two older holes, about a third of the way from ~est well 2 to test well 4, and penetrated the same section, except that it wàs not drilled quite as deep. It was successfully completed as a gas well and proved to be better than the the other two, producing at a maxi- mum stabilized rate of 7.9 million cubic feet per day, or at a safe productive rate of 1.4 million cubic feet per day, with no water.

Total depth: 779 feet. Skull Cliff core test 1 is 1}~ miles inland from the shore of the Arctic Ocean, and about 40 miles south- west of Point Barrow. The coastline in this area is bordered by a cliff some 50 feet high, in which Pleisto- cene and Cretaceous beds crop out. Oil drips slowly from a seep at the base of the cliff; Edward J. Webber described it (written communication, 1947)· as coming from a spot a few inches across, in a sandstone bed which crops out along the edge of the ocean. Except for the cliff face, there are no outcrops anywhere in the area, and the need for additional stratigraphic information, as well as the oil seep, determined the location of the hole. It was planned as a 1,500-foot test, but mechan- ical difficulties caused abandonment at a total depth of 779 feet. A V AK TES1' WELL 1 Location: Lat 71 °15'02" N., long 156°28'06" 'V.

Avak test well 1 was drilled on the north side of this area, almost 4 miles east- southeast of South Barrow test well 2, in an attempt to determine whether oil or gas were trapped by the anomaly, and also to learn more about the pre-Mesozoic rocks of the area at a place where they were most easily reached by the drill. Although it discovered only slight shows of oil and was abandoned as a dry hole, the test demonstrated that the area is very complex structurally, with Cretaceous and Jurassic beds dipping at many angles from 20° to vertical. "... Between 310 and 820 feet, however, one core and many of the ditch samples are composed of medium-gray silty and sandy clay shale similar to Lower Jurassic rocks in the area. These beds may well be displaced from their normal position beneath the pebble shale by faulting; the abnormally thick section and variable dips also suggest structural complexity. "Below the lowest pebble shale strata are clay shale and silty sandstone with clay intercalations, typical of Lower Jurassic deposits. A Sinemurian fossil from the sandstone at 1,836 feet corroborates this age designation. The clay shale is concentrated in the upper and lower parts of the sequence, from 1,350 to 1,600 feet, and from 1,900 to 2,280 , the intervening 300 feet is occupied by argillaceous sandstone which had slight shows of oil. The basal 27 feet of the section from 2,280 to 2,307 feet, is composed of conglomerate. "Beneath the conglomerate is argillite similar to that at the bottoms of the other Barrow test wells. ..." . .
