A final plug and abandonment was successfully preformed. Wellsite equipment was demobilized on April 19, 2017. Work Objective The priorities of the attached Plug and Abandonment Procedure for South Barrow Test#3 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 spudded in July 1949 then abandoned in August 1949 with an ice plug. No cement was placed in the wellbore. • Well was flow tested twice @ 2,800'. Recorded "fair blow"then "slight blow" of gas with a recorded BHP of 375 psi. • 10.2 ppg drlg mud left in well from 800' to PBTD. 800' of fresh water placed in upper part of wellbore as an ice plug. The annulus of the 16" x conductor csg is cemented to surface 78 sxs of cement. 11 3/"x 16" csg annulus cemented with 103 sxs of cement. • Found cable inside 11 3/4" casing during 2017 P&A. South Barrow Test#3 Final Abandonment Notice Sundry 5-1-17 Page 2 of 19 • • Pa.0 t Rpsoma4 A1444 N1ARSHCREFK Variance Bureau of Land Management(BLM)acknowledges that the South Barrow Test#3 does not meet the requirements of Onshore Oil and Gas Order No.2(Onshore Order No.2). The AOGCC Sundry 10-403 for South Barrow Test#3 contains a significant error on the schematic, noting no producible hydrocarbons penetrated in the well. BLM agrees to notify AOGCC of the error. After performing the due-diligence and comparing the Scope of Work Schematics for South Barrow Test#3,the well history revealed the P&A Sundry is deficient as follows: South Barrow Test#3 1. Found to have been Drill-Stem flow tested @ 2900' in 1949 with a"fair blow"for 35 min and"slight blow"for 37 min. then left the well with an 800' ice plug(43 CFR 3160"Onshore Oil and Gas Order No. 2, Drilling Operations", Section G, 1). 2. 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 South Barrow Test#3 to meet Onshore Order No.2(43 CFR 3160"Onshore Oil and Gas Order No. 2, Drilling Operations", Section G, 1 &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." Daily Operations Summary Prior to mob area around well was excavated, refer to previous QC report for details.

This will achieve the same well objectives and will allow for a greater than 150' cement plug measured from the 11 3/4"casing stub. No Arctic Cement Platform(ACP)is required since we have an ice plug in the well. Will eliminate steps 12-14 in Sundry Change Request#1 procedure. This is the driver for cleaning out the well to a shallower depth. Describe the Reason for the Change: We have a solid ice bottom for the cement and the ACP is not required.

Identify surface location of the well and check the area for potential gas. 2. Remove general debris from cellar and carefully excavate same to remove all surface concrete and expose the 11 3/" casing. Excavate around csg to obtain a desired working height. 3. Identify condition of surface csg strings and top of ice in the wellbore. 4. Move in Spot surface required support equip. 5. Weld on flange to the 11 3/4" casing to accommodate the 4 1/16" BOP Stack. Operations: 6. NU 4 1/16" BOP. Close blinds. Shell test BOP to 250 psi low and 500 psi high for 30 min each against ice plug in wellbore. Manifold returns to open top tank(s). Bleed down to zero. Reference:Onshore Oil and Gas Order No. 2, Drilling Operations/111. Requirements/A. Well Control Requirements/2./i 7. If unable to pressure test against ice plug BOP pressure test will be waived, a function test will be performed and BOP system will be used as a diverter. 8. Build 9.8 ppg NaCI brine. Preheat to 130°F. Load well with brine 9. If top of ice plug based of well bore fill is below 170' thawing will not be required 10. RIH w/ 1.9"WS while circulating warm brine to 170' MD or until refusal. Expect ice the entire duration as the base of 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. 12. Mix/Blend 20 bbls of ArcticSetl cement(5 super sxs). Note: Slurry Density: 15.70 lb/gal, Yield: 0.93 ft3/sk, Mix Fluid: 3.544 gal/sk. 13. Pump/displace wellbore from 170' to surface with 20 bbls of cement down Workstring (WS). POOH. 14. WOC for a minimum of 6 hrs. RIH w/WS. Tag TOC w/500 lbs of wt. to verify plug has not fallen downhole. 15. Cut/remove BOP flange. 16. Ensure all annuluses are full of cement As required utilize 1"work string to steam/melt the annulus between the 11 3/" csg and 16" conductor to a depth of 60>or until refusal. Mix/Blend/Pump ArcticSetl cement in the annulus. Shut down when cement is at surface. 17. Cut Tubulars min of 5' below ground level. Ensure all annuluses are full of cement. 18. Weld on a marker plate on the outermost casing (unknown conductor size set at 32 feet BGL)that meets current BLM regulations. 19. Backfill excavated hole and mound the excavation with gravel or tundra organics to account for settling. 20. Remove any remaining wood or steel pilings and debris from the surface of the location and proceed with disposal of waste materials from the site. 21. Return to the site the following summer for stick pick operations.

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 South Barrow Test#3 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 South Barrow Test#3 does not meet the requirements of Onshore Oil and Gas Order No. 2 (Onshore Order No. 2). The AOGCC Sundry 10-403 for South Barrow Test#3 contains a significant error on the schematic,noting no producible hydrocarbons penetrated in the well. BLM agrees to notify AOGCC of the error. After performing the due-diligence and comparing the Scope of Work Schematics for South Barrow Test#3,the well history revealed the P&A Sundry is deficient as follows: South Barrow Test#3 1. Found to have been Drill-Stem flow tested @ 2900'in 1949 with a "fair blow"for 35 min and "slight blow"for 37 min.then left the well with an 800'ice plug (43 CFR 3160"Onshore Oil and Gas Order No.2, Drilling Operations",Section G, 1). 2. 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 South Barrow Test#3 to meet Onshore Order No, 2 (43 CFR 3160 "Onshore Oil and Gas Order No. 2, Drilling Operations",Section G, 1&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 spudded in July 1949 then abandoned in August 1949 with an ice plug. No cement was placed in the wellbore. • Well was flow tested twice @ 2,800'.Recorded`fair blow"then "slight blow"of gas with a recorded BHP of 375 psi. • 10.2 ppg drig mud left in well from 800'to PB TD. • 800'of fresh water placed in upper part of wellbore as an ice plug. • A welisite inspection in May 2013 noted that the 11 %"csg has been cut off at ground level.A 4"pipe, identifying the well location and associated csg cap, is not attached to the 11 %"csg. S. Barrow Test#3 Sundry(Jan-24-2017) Page 2 of 7 P4,44.4..4 At$44 1[S,RS UC'R:EEK • The annulus of the 16"x conductor csg is cemented to surface 78 sxs of cement. • 11 %"x 16"csg annulus cemented with 103 sxs of cement. Sundry Procedure Pre-Rig Ops: 1. Identify surface location of the well and check the area for potential gas. 2. Remove general debris from cellar and carefully excavate same to remove all surface concrete and expose the 113/"casing. Excavate around csg to obtain a desired working height. Remove wood pilings and steel beams obstructing the work area. 3. Identify condition of surface csg strings and top of ice in the wellbore. 4. Move in required equipment, cement batch mixer, heaters, boiler,circulating tanks, piping,generators, scaffolding,tarps, and other wellsite equipment. 5. Spot surface support equip and 30 Ton National Cab Mounted Boom Truck. 6. Weld on flange to the 113/1"casing to accommodate the 4 1/16' BOPE Stack. Operations: 7. NU BOP.Close blinds.Shell test BOP to 250 psi low and 500 psi high for 30 min each against ice plug in wellbore. Manifold returns to open top tank(s). Bleed down to zero.

Barrow Test Well#3-Plug and Abandonment Procedure OVERVIEW During the winter of 2015—2016 BLM has contracted Marsh Creek and SolstenXP to perform the successful abandonment of legacy wells drilled in NPRA along with the remediation of the location. 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 was drilled in 1949 and supposedly abandoned in 1988. During the drilling of this well losses were experienced and manage the losses at TD the top 800 feet of the 10.2 ppg drilling fluid were replaced with 8.33 ppg fresh water.The wellhead has been removed from this well and all of the casings have been cut off at ground level.

Identify surface location of the well and check the area for potential gas. 2. Remove general debris from cellar and carefully excavate same to remove all surface concrete and expose the 11 34 inch casini Also remove any wood piling obstructing the work area. 3. Identify condition of surface casing strings and top of ice in the wellbore.Records indicate that the 11 3/4 inch casing has been cut off at ground level and the 4 inch pipe identifying the well location and associated casing cap is not attached to the 11'/inch casing.The annulus of the 16 inch x conductor casing is cemented to surface and the 11%x 16 inch casing annulus should contain frozen drillingmud. 4. Move in required equipment,cement batch mixer,heaters,boiler,circulating tanks,piping,generators, scaffolding,tarps,and other wellsite equipment. 5. Weld on a riser and flange to the 11%inch casing at the desired height for circulating. 6. Rig up BOP equipment and direct returns to open top tank. Swat.Crceo $trpE To SCO PStq, 7. Run tubing in the well and circulate warm brine to melt frozen fluids to a depth of 164 feet RKB or until v refusal. Expect ice the entire duration as the base of permafrost is reported at 1,330 feet RKB. Refusal is defined as not being able to make further progress after 30 minutes of circulating. In this case,notify BLM r 4Ct,Lu officials that an impassable bridge has been encountered and that cement will be set at a shallower depth than the target depth. 8. Circulate warm brine until the returns are consistent and have the desired freeze protection properties. 9. Line-up surface piping to allow cement returns to be taken in an open top waste tank. 10. Proceed to pump a sufficient volume of Artic-Set cement to fill the wellbore from 164 feet to surface. 41 2,0 61„k 11. Wait on cement from minimum 6 hours and verify if the plug has fallen downhole. C6r+G.'t 12. Excavate around the well to a minimum depth of 6 feet BGL. 13. Cut hole in the wall of the 16 inch casing and install a flow nipple to take returns into a 55 gallon drum cut in half that is placed adjacent to the well. 14. Begin steaming/melting the annulus between the 11 3/4 inch casing and the 16 inch conductor to a depth 9f 60 feet or refusal.Collect returns with a vac unit. 15. Proceed to pump as much is 6 barrels of Arctic-Set cement in the annulus between the 16 inch conductor and 11%inch casing.Vacuum returns into a vac unit.Watch for cement returns at surface andhu down vac unit when cement to surface. 20 APA. 2.S,11-2-14)(1VV 1-'a t.A0r d A/J 16.

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.

ADEC has also reviewed the response by the Alaska Oil and Gas Conservation Commission (AOGC). We concur with the response by AOGC and have no further comment regarding the priorities. We do have comments about the investigation and cleanup plans presented in the report. With this letter we are outlining regulatory requirements related to the environmental work that is proposed and required as part of these cleanups. ADEC is concerned that the 2013 Legacy Wells Strategic Plan prepared by the BLM does not include either assessment or the contingency for assessment of known,likely, or unknown but possible contaminant releases. In addition,BLM plans for surface cleanup of these wells should be made clear in the plan. At least one of these legacy wells has extensive PCB contamination and has resulted in a multi-year cleanup totaling tens of millions of dollars. At others, solid waste disposal practices have resulted in releases to the environment with estimated cleanup costs in the hundreds of millions. Known releases documented in the records we reviewed include crude oil,gasses,refined oil and fuel, drilling fluids that include various organics,metals,and other chemicals, and unknown contaminants from drums and other containers observed to be damaged and abandoned at the various well sites. There are 13 legacy well sites with known releases currently on the DEC contaminated sites list. Many of these are in the process of being addressed,cleaned up, and closed. From our limited records review there are 15 additional legacy well sites with confirmed releases. These should be prioritized for initial records reviews and then added to the BLM contaminated sites list under our cooperative agreement. Suspected releases include fuel releases from operations, storage, and fuel spills at the sites,impacts to various surface water bodies from spilled fluids during drilling and breaches of containment at reserve and flare pits, continued surface runoff from drilling fluids uncontained at several sites, and down-hole substances that were ejected from the holes over time or during blowouts or drilling operations. , Wayne Svejnoha 2 July 11, 2013 The BLM plan to address these known, suspected, and unknown releases at legacy well sites is notably absent from the documents presented to date. The three primary regulatory agencies that need to be involved in the plan are ADEC —Contaminated Sites,Alaska Oil& Gas Conservation Commission, and ADEC —EH/Solid Waste. Other agencies will need to be consulted as well. Below we provide recommendations for a coordinated plan using the Uniform Federal Policy for Quality Assurance Project Plans (UFP-QAPP) that will involve all of the regulatory agencies in one coordinated manner. This will allow BLM to address these sites in a consistent and coordinated project which fulfills all of the regulatory requirements so that the sites do not need to be re-visited in the future when they are closed after this project. Attached are our comments on each specific well. The acronyms used on the list include terms that are typically used in a CERCLA type investigation however they are also suitable for investigations conducted under the State of Alaska cleanup rules. These include the following; Historical Records Review (HRR) This is recommended for almost all of the well sites. Much of the information required for these reviews is already contained in various reports and appendices or in BLM files. The Historical Records Review should document the type of releases that might have occurred from drilling operations as well as historical use of the site, and should capture all available information on the drilling fluids used and any product produced or released. Preliminary Assessment (PA) This is recommended for almost all of the well sites. A Preliminary Assessment is a limited scope investigation that provides an assessment of information about a site and its surrounding area to distinguish between sites that pose little or no threat to human health or the environment and sites that require further investigation. The PA is a CERCLA defined document and typically does not require sampling. Site Inspection (SI) If the PA recommends further investigation, then an SI is necessary. The SI is a CERCLA defined document, and it is analogous to an initial report of contamination under state cleanup rules. On some legacy well drillings sites it is evident now that an SI is required just from a review of the reports. An SI investigation typically includes the collection of samples to determine what contaminants are present at the site and whether they are being released into the environment. An approved site specific workplan is required under both CERCLA and 18 AAC 75 prior to SI sampling. The SI typically is not intended to develop a full site characterization, but is limited to determining the presence or absence of a release. If contamination is found after completion of the HRR,PA, and SI then a RI/FS under CERCLA, or a Site Characterization Report and cleanup plan under 18 AAC 75 is required. DEC recommends that BLM incorporate into the strategic plan the processes outlined in this letter. A team of agencies composed of AOGC, DEC-CS, EPA as required,and DEC-EH should address regulatory and technical requirements for these well closures. By cooperating and working together with the regulatory agencies BLM will save time and expense, and regulatory uncertainties will be avoided. The strategic plan should reference a project to prepare a generic workplan. DEC suggests that BLM utilize the generic UFP-QAPP workplan format for the required environmental work. If properly prepared,the workplan could encompass most of the investigations and cleanups required at these sites over multiple years. At other multi-site projects we have found this to be an effective way to reduce uncertainties and risk in these types of investigations. A very small site specific FSP could then be developed as BLM approaches each drilling site. Regulatory decisions made during workplan development would provide more certainty in the planning process for cleanups. n•\en A n\re\FoA<.t Fn.dt:evPC\r■v,a:q„Fadrra1 A aPnriec\nni\RJ.M\Proiects\Le¢acv Wells\7 11 13 Letter to BLM on Leeacv Wells.docx Wayne Svejnoha 3 July 11, 2013 Please review the attached list of specific sites.

The South Barrow #3 site is approximately 10 miles south of Barrow. This well is within the Northwest National Petroleum Reserve in Alaska (NPR -A) and is on privately owned land, with oil and gas reserved to the North Slope Borough. However, the well remains in federal ownership, as it was specifically excluded from conveyance in the Barrow Transfer Act of 1984. The last site inspection was in July 2012. Site Description: The South Barrow #3 site consists of a well, along with associated scattered surface remains in an area measuring approximately 120 feet north to south by 50 feet east to west [Figure 1]. The U.S. Navy drilled the well in 1949. There is no pad or reserve pit associated with the well. The well is located within a concrete cellar that measures 8 feet by 8 feet and is 16 inches above the ground surface. The concrete cellar was constructed in an area that was excavated 10 inches below the ground surface. Two wooden pilings were embedded in each of the east and west concrete walls. These pilings have a diameter of about 10 inches and the two southernmost extend 3 feet above the ground surface, while the northernmost pilings are 2 feet above the ground surface [Figure 2]. Two metal I -beams rest on top of the pilings and are assumed to be the only remains of the massive substructure that held the well platform and drilling rig. At least 85 additional pilings are present on the site, extending 50 feet both north and south away from the well cellar in an evenly- spaced pattern. The pilings all have a diameter of about 10 inches and vary from 3- to 24- inches above the ground surface [Figure 3]. Some of the pilings have been soaked in creosote and are identified by their black color [Figure 4]. The concrete cellar has standing water in the bottom and has been filled with a variety of debris [Figure 5]. The well itself consists of an open -ended 10 -inch casing that is cut off at the ground surface [Figure 6]. Above the well opening is a constructed 4 -inch diameter pipe tripod measuring 4 feet tall by 3 feet wide at the base. The pipe tripod was intentionally constructed to be placed over the well opening but has shifted, leaving the well open to the elements. Additional debris present within the cellar includes a 55- gallon metal drum filled with soil and vegetation growing out of the top; several small pieces of metal plate cut into a variety of shapes, several small sections of 4 -inch diameter pipe, several small pieces of metal military Marsden Matting, several small pieces of 12 -inch diameter metal tubing, numerous concrete chunks, and a few rusted tin cans. Surface Risk Assessment: Medium. Justification: There are no known contaminants present at the site. Based on the visual inspection, there is no indication that that well or any of the associated surface debris has the potential to affect surface water. While there are ponds and a seasonal stream channel adjacent to the site, the site is not under threat from erosion. With the proximity of the site to the community of Barrow, however, there is a potential for the site to pose a travel hazard to local residents utilizing snow machines. The BLM will need to prepare a determination of eligibility pursuant to Section 106 of the National Historic Preservation Act. If the site is determined not eligible, then the surface debris should be removed as funding allows or in conjunction with other scheduled operations, if possible. 154 BLM Open File Report 127 • February 2013 • • Legacy Wells Summary Report Section 2: Wells BLM Monitors 4 .-. . ., � — ` -' • - s "Ifw ; mow: y"" .. . • .

BLM Open File Report 127 • February 2013 157 Section 2: Wells BLM Monitors Legacy Wells Summary Report SUBSURFACE INFORMATION Well Information: • Well History: The South Barrow #3 was drilled 10 miles south of Barrow over the summer of 1949 to a total depth of 2,900 feet [Figure 7]. The purpose of the well was to test a structural high area with a closure. • Well Condition: The well consists of an open -ended 4 -inch pipe welded to a plate that covers 11 % -inch casing. The plate cover removes easily. • Wellhead Components: There is no wellhead at this site. Geologic Setting: A slight oil show was discovered in the Mesozoic beds of the Torok Formation, but was not sufficient to produce oil in drill -stem tests. Another drill -stem test conducted in the argillite basement rocks between 2,800 and 2,900 feet resulted in a fair blow for 35 minutes before becoming plugged. Other slight gas shows occurred in the Barrow sand and within the Shublik Formation, which also contained visible oil cuts (Collins and Brewer 1961). Development Potential: Exploration and development in the vicinity of this well is a remote possibility within the next 20 years. It is unlikely this well will have an adverse impact on development in its current state. The BLM plans to properly plug this well within the next 2 years if funding is available. Groundwater Resource: There are no groundwater resources present in this area. Continuous permafrost is about 440 meters thick throughout the entire Barrow region. Freshwater aquifers are not present. The town of Barrow gets its drinking water from treated surface water, not from aquifers (Alaska Department of Environmental Conservation 2012). Other Information: There is no indication of hydrocarbon escapement at this location. 158 BLM Open File Report 127 • February 2013 • • Legacy Wells Summary Report Section 2: Wells BLM Monitors eAti., 1 kvv,,i El l :11 1-3 cazia;.: nQrfr ci rcor plpF) 6. 40 r 'C1 1 plc t s 13ao 3 cbs 1 Vzi; cv:meivrsd 17 3 sx ssrncst 1j L o '4 11-t e abancoo.ez e i& fl ..4...pt par'. wt.:dtd tsWr 11 34 caso: 4' 01 4 p 1:W■‘ '403eft 13 the trp .1as lomtion arkericaL,e r,L.ppol 2t.ki 250G Fm4reri 11) of 2'.0.■1 ccomfing to ete krig rc:ords • 3.1)OCT i Figure 7: South Barrow #3 wellbore diagram. t9001- e p 4,A 1„111 BLM Open File Report 127 • February 2013 159 , k- ; e • C____i Art i BARROW CORE RIG TEST 1 r M ; G � r� E ,mac / m /,,;- s A/ : va Location: Lat 71 °19'25" N., long 156 °39'02" WV. / Elevation: Ground, 10.4 feet; top of surface pipe, 13 feet.

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 -1 is Early- Middle( ?) Jurassic and coincides with foraminiferal zones F -17 and F -18 (Anderson, Warren, and Associates, 1974 - 1979). The thickness of J -1 is related to its truncation by the The overlying m Jurassic and basal "Pebble Shale" unconformities. section penetrated is 1,038 ft (316 m) thick at East Teshekpuk 1; this section extends to the west and parallels the Barrow Arch. Northward, ` toward the Barrow High and the Barrow Arch, unit J-1 is p rog r es si vely In truncated by the basal "Pebble Shale" unconformity. of the NPRA, the mid - Jurassic unconformity deeply truncates J -1 toward the southeast; J -1 thickness ranges from 580 ft (177 m) at Ikpikpuk 1 to 136 ft -(42 m) At North Inigok 1. • • . r_ - In the western half of the Reserve, truncation by the basal- "Pebble Shale" 1 . unconformity is more gradual, and 140 ft (43 m) of J-1 truncates s present Ja I -; T Ther- J midurassic unconformity probably completely an west :direction across the middle of the NPRA. - - - lfnfit'=J =1 consfists of cyclfcatly deposited shale units- that Coarsen upr+a into siltstone or sandstone.

East of the Dease Inlet, the basal "Pebble Shale" unconformity truncates TR -3a. The truncation zone runs roughly east -west and is just north of J. W. Dalton 1 and W. T. Foran 1. West of Dease Inlet, the unit onlaps the Barrow High. Thicknesses of TR -3a at East Teshekpuk 1 and West Creek Creek 1 indicate thinning over the Fish 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 Tunal i k 1 and thins northeastward toward the Barrow High. Lithology and high gamma -ray 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 commons occur the a r t mineral in the sandstones, and thin shell beds interval. Sand -shale ratios and clastic ratios indicate that the best sand development is in the northwestern part of the Reserve. High sand -shale ratios at Peard 1, Walakpa es1 Walak a pr , and Iko Bay 1 indicate a source area ard shoreline. TR -3a is p c9careous l toward the south � Over the southeast and more al Fish Creek Platform, the amount of limestone present increases significantly. At South Harrison Bay 1, the unit is mostly limestone. At Lisburne 1, with no nearby control, arenaceous limestone is indicated. Apparent lithologic anomalies occur at East Simpson 2 where the unit is interbedded siltstone and limestone and Drew Point 1 where the high sand count may be caused by statistical variations, or may indicate a small barlike body flanking the Barrow High. rsopa�.�t 9I-l.T rio1iz,` es 1 %a p T_� eARROW so•6 •nii Te I�' ONLAP ONTO BARROW HIGH (LOGS) rvt. e. -0-1t Pi r?l a� e ,/>b +' 7� - T BASED ON SEISMIC • • 4 y RPRETATION.

Drilling started on Juno 23, 1949; although slight shown of oil and as were found, formation tests showed none to be commercial, and the well was abandoned on ::sly 26, 1949. Only a thin blanket (some 20 feet) of Gubik sand and gravel (Plsistocene) is owssent at South Barrow No, 3. Below it, the Colville (Zone I, Cretaceous) Grow) continues to the Colville-Nanushuk boundar7 between 1050 and 1200 (nrobably about 1101t). The D-17 Zone of the Tfanushfr Group (Cretaceous) is thin, its base being arnroximately 13 the AZ Zone begins at 1340 An ammonite collection from oores between 1772 and 2199 permitted a close age correlation of that interval with thn Lower Jurassic (U-sner Plienebachian and Lower Toarcian) of nslrope. The Triassic is encountered at 2547°, and is marked by an abundance of T:onotis (pelecrood) shells from 2635 down, and a distinctive lithologr characterized by oolitic limonite and an abundance of oresaish gray siltstono. Basement directly underlies the Triassic at a derth of 2799 L1TPOLOGY The following description is based on data from cores, ditch, electric log and well esologista report; age determinations denended largely on microfaunal studles by Harlan R. nerequist and Irs. Palen N, Loeblich, and on armonito identifications by Dr. R. U. Zmlay. The firot dtch zartslos, the hhent of wLich io st 63 o, ocorlot of Gubik gravel (eubangular to rounded pebbles -;" or less in diameter, are largely of flack chart): and minor amounts of Cubik sand (coarse to fine, with kligh sphericity, rounded to mass rounded, frosted to noliehed surfaces, mostly of clear quarts but also having small amounts of white and yellow auartz; rare clear quartz grains are ansular, with isnweat! urfaces), with a small nuantity of typically Colville sand (which is described. under Core 1, below). The well geologist le report describes the litholosy above 40' as beiss3 soft blue-Eray clay, and from 470 to 109 as soft blue-gray clay with carbonaceous particlee and sandy streaks. Its this description fits the Colville bettor than t3 Gubik, and as the /ithologv above the highest ditch sample is similar to that - z)z111 it the Gubik is considered to be a thin gravelly blanket - orobably not mud l thichos thssn the depth of the canes beneath the rig.
