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

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

ADEC has also reviewed the response by the Alaska Oil and Gas Conservation Commission (AOGC). We concur with the response by AOGC and have no further comment regarding the priorities. We do have comments about the investigation and cleanup plans presented in the report. With this letter we are outlining regulatory requirements related to the environmental work that is proposed and required as part of these cleanups. ADEC is concerned that the 2013 Legacy Wells Strategic Plan prepared by the BLM does not include either assessment or the contingency for assessment of known,likely, or unknown but possible contaminant releases. In addition,BLM plans for surface cleanup of these wells should be made clear in the plan. At least one of these legacy wells has extensive PCB contamination and has resulted in a multi-year cleanup totaling tens of millions of dollars. At others, solid waste disposal practices have resulted in releases to the environment with estimated cleanup costs in the hundreds of millions. Known releases documented in the records we reviewed include crude oil,gasses,refined oil and fuel, drilling fluids that include various organics,metals, and other chemicals, and unknown contaminants from drums and other containers observed to be damaged and abandoned at the various well sites. There are 13 legacy well sites with known releases currently on the DEC contaminated sites list. Many of these are in the • process of being addressed, cleaned up, and closed. From our limited records review there are 15 additional legacy well sites with confirmed releases. These should be prioritized for initial records reviews and then added to the BLM contaminated sites list under our cooperative agreement. Suspected releases include fuel releases from operations, storage, and fuel spills at the sites,impacts to various surface water bodies from spilled fluids during drilling and breaches of containment at reserve and flare pits, continued surface runoff from drilling fluids uncontained at several sites, and down-hole substances that were ejected from the holes over time or during blowouts or drilling operations. , Wayne Svejnoha 2 July 11, 2013 The BLM plan to address these known, suspected, and unknown releases at legacy well sites is notably absent from the documents presented to date. The three primary regulatory agencies that need to be involved in the plan are ADEC —Contaminated Sites,Alaska Oil& Gas Conservation Commission, and ADEC—EH/Solid Waste. Other agencies will need to be consulted as well. Below we provide recommendations for a coordinated plan using the Uniform Federal Policy for Quality Assurance Project Plans (UFP-QAPP) that will involve all of the regulatory agencies in one coordinated manner. This will allow BLM to address these sites in a consistent and coordinated project which fulfills all of the regulatory requirements so that the sites do not need to be re-visited in the future when they are closed after this project. Attached are our comments on each specific well. The acronyms used on the list include terms that are typically used in a CERCLA type investigation however they are also suitable for investigations conducted under the State of Alaska cleanup rules. These include the following; Historical Records Review (HRR) This is recommended for almost all of the well sites. Much of the information required for these reviews is already contained in various reports and appendices or in BLM files. The Historical Records Review should document the type of releases that might have occurred from drilling operations as well as historical use of the site, and should capture all available information on the drilling fluids used and any product produced or released. Preliminary Assessment (PA) This is recommended for almost all of the well sites. A Preliminary Assessment is a limited scope investigation that provides an assessment of information about a site and its surrounding area to distinguish between sites that pose little or no threat to human health or the environment and sites that require further investigation. The PA is a CERCLA defined document and typically does not require sampling. Site Inspection (SI) If the PA recommends further investigation, then an SI is necessary. The SI is a CERCLA defined document, and it is analogous to an initial report of contamination under state cleanup rules. On some legacy well drillings sites it is evident now that an SI is required just from a review of the reports. An SI investigation typically includes the collection of samples to determine what contaminants are present at the site and whether they are being released into the environment. An approved site specific workplan is required under both CERCLA and 18 AAC 75 prior to SI sampling. The SI typically is not intended to develop a full site characterization, but is limited to determining the presence or absence of a release. If contamination is found after completion of the HRR,PA, and SI then a RI/FS under CERCLA, or a Site Characterization Report and cleanup plan under 18 AAC 75 is required. DEC recommends that BLM incorporate into the strategic plan the processes outlined in this letter. A team of agencies composed of AOGC,DEC-CS, EPA as required,and DEC-EH should address regulatory and technical requirements for these well closures. By cooperating and working together with the regulatory agencies BLM will save time and expense,and regulatory uncertainties will be avoided. The strategic plan should reference a project to prepare a generic workplan. DEC suggests that BLM utilize the generic UFP-QAPP workplan format for the required environmental work. If properly prepared, the workplan could encompass most of the investigations and cleanups required at these sites over multiple years. At other multi-site projects we have found this to be an effective way to reduce uncertainties and risk in these types of investigations. A very small site specific FSP could then be developed as BLM approaches each drilling site. Regulatory decisions made during workplan development would provide more certainty in the planning process for cleanups. r_•\c1AU\CC\ FrriP.al A eq\flflT\RT.M\Proiects\Leacv Wells\7 1113 Letter to BLM on Legacy Wells.docx Wayne Svejnoha 3 July 11 2013 Please review the attached list of specific sites.

As you know the following wells were Plugged and Abandoned over the course of the project. Walakpa #2 NSB -02 SB -13 SB -11 SB -08 EB -20 EB -19 EB -21 EB -15 For each well the Plug and Abandonment procedure was followed by Peak. After Haliburton completed the cement job, our crews excavated around the wellhead. Once the area was excavated and a confined space permit was opened, a measurement was taken from the existing ground level down three feet. In each case a representative of PRA or the NSB was on site to ensure that the cut off mark was 3 ft below the existing ground level. Once this cut off mark was verified, the well head was cut off, either with a cutting torch or in one case, with a guillotine saw. At this point Halliburton came back and completed a top job for the wells in which it was needed, the well maker plate was welded on and the excavated area was backfilled. This can be confirmed by the photos that were taken during the procedures and by the PRA & NSB representatives. If you have any questions or need any additional information please don't hesitate to contact me.

Guy Guy Schwartz Senior Petroleum Engineer AOGCC 793 -1226 (office) 444 -3433 (cell) Original Message From: Tom Walsh [mailto:twalsh @petroak.com] Sent: Wednesday, April 11, 2012 4:54 PM To: Schwartz, Guy L (DOA) Cc: Pete Stokes; Matt Coullahan; Michael Cook Subject: RE: Walakpa #13 Production Hole Section Extension to 5800 ' md/rkb Guy, Our field team has asked for a modification of the procedure for abandoning the EB -20 well, as we have no means of circulating out fluid known to be in the production tubing. We connected to the tubing and inner annulus today and pressured up to 1500 psi on each separately, with no pressure loss, much as was recorded in 1988 notes when both sides held 2500 psi. We would like to run a tubing punch in to the tubing to puch a hole through to the inner annulus at a starting depth of 400', establish that we have the ability to circulate out the fluids, and then pump cement to fill both tubing and annulus, we cement returns to surface as in previous jobs. I've attached the revised procedure, and wonder what we would have to do to have this revision approved. They are rigged up on the well now.

Prior to excavation, either the onsite company man or a surveyor will mark the existing ground level on the conductor pipe. 8. Excavate around the conductor casing at 6 ft below ground level. Peak will utilize either a 200 or 400 size excavator, rented from Umiaq, with a frost bucket. 9. The size of the excavation will be roughly 5 ft from the conductor casing to the bottom edge of the excavation. Three sides of the excavation will have side slopes of 1:1. The fourth side of the excavation will have a side slope of 3:1. This will allow easier access into the excavation for cutting off the conductor. 10. Prior to entering the excavation, a confined space permit will be opened. This includes testing with an atmospheric testing meter. 11. The cut mark on the conductor casing will be measured 3 ft below the initial existing ground mark, made prior to excavation. The welder will then mark the cut line around the conductor. A second line will be marked roughly 1 ft above the cut line. 12. A drill will be used to drill 3 to 4 small holes 1/4" to '''4" in diameter along the cut line. As the welder drills through the metal pipe, he will look to see if there are cement cuttings as well as metal. 13. The atmospheric testing meter will be used to test the air inside of the conductor at each of drill holes. 14. Prior to cutting, the excavator bucket will be extended over the tree. The tree will be attached to the excavator with approved lifting devices (straps). The bucket will be raised to load the attached straps in tension. 15. Once it has been verified that the air is suitable for hot work, the welder will begin cutting the conductor along the first cut line. He will also cut on the line roughly one ft above the bottom cut line. In two places he will cut from line to line. (Peak will fill out the clients hot work permit if required for cutting the pipe). 16. This section of the pipe will be removed. 17. The cement from inside the conductor pipe will be removed. 18. Steps 15, 16, 18, 19, and 20 will be repeated for each section of pipe. 19. After the final cut has been made the excavator will be used to raise the tree and pipe and set to the side. 20. The company man will verify that the cement is to the top of the pipes. 21. The welder will weld the top plate to the top of the conductor. 22. Pictures will be taken by the company man. 23. All equipment will be removed from the conductor hole and backfill around the conductor will begin with the existing material. Additional gravel will be brought in to dress the fill, leaving a mound above the conductor pipe to account for eventual settling of the material. At least 30% overfill will be used to account for the settling. 24. The tree will be hauled to the land fill and other equipment demobilized.

Prior to excavation, either the onsite company man or a surveyor will mark the existing ground level on the conductor pipe. 11. Excavate around the conductor casing at 6 ft below ground level. Peak will utilize either a 200 or 400 size excavator, rented from Umiaq, with a frost bucket. 12. The size of the excavation will be roughly 5 ft from the conductor casing to the bottom edge of the excavation. Three sides of the excavation will have side slopes of 1:1. The fourth side of the excavation will have a side slope of 3:1. This will allow easier access into the excavation for cutting off the conductor. 13. Prior to entering the excavation, a confined space permit will be opened. This includes testing with an atmospheric testing meter. 14. The cut mark on the conductor casing will be measured 3 ft below the initial existing ground mark, made prior to excavation. The welder will then mark the cut line around the conductor. A second line will be marked roughly 1 ft above the cut line. 15. A drill will be used to drill 3 to 4 small holes 1 /4" to %" in diameter along the cut line. As the welder drills through the metal pipe, he will look to see if there are cement cuttings as well as metal. 16. The atmospheric testing meter will be used to test the air inside of the conductor at each a of drill holes. 17. Prior to cutting, the excavator bucket will be extended over the tree. The tree will be attached to the excavator with approved lifting devices (straps). The bucket will be raised to load the attached straps in tension. 18. Once it has been verified that the air is suitable for hot work, the welder will begin cutting the conductor along the first cut line. He will also cut on the line roughly one ft above the bottom cut line. In two places he will cut from line to line. (Peak will fill out the clients hot work permit if required for cutting the pipe). 19. This section of the pipe will be removed. 20. The cement from inside the conductor pipe will be removed. 21. Steps 15, 16, 18, 19, and 20 will be repeated for each section of pipe. 22. After the final cut has been made the excavator will be used to raise the tree and pipe and set to the side. 23. The company man will verify that the cement is to the top of the pipes. 24. The welder will weld the top plate to the top of the conductor. -- r 1 r ?'° A'4 C' Z S. (Lo 25.

A!:::'::~ & Gas Cens. tJ1Cl'1~'faGa .. e e PRODUCTION TEST NO.3 "Pebble Shale" sands CONCLUSIONS 1. The reservoir produced mainly water and oil, not gas. 2. Temperatures of the producing zones, 1556-1574' and 1629-1639', were approximately 40°F. 3. Initial reservoir pressure CPt) was at least 436 psia. 4. There. was fluid influx into the wellbore and redistribution of these fluids within the wellbore. 5. The well would produce 'at a maximum rate of approximately 20-25 SOPD. DISCUSSION A standard flow after flow production test was attempted as suggested by H. J. G ruyand Associates. This test was impossible to carry out as planned due ~o rapid decline in pressu re and flow rates. Fluid flow into the wellbore was slow due to the high viscosities at low temperatu reo The pressure buildup plot indicates that fluids entered the wellbore and redistributed within the fluid column. If the only gas produced from South Barrow No. 20 was that which was injected from. Well No. 19, a wellbore to formation pressure differential of 330 psi may have been created. This pressure difference was created by the pressure drawdown during flow, reducing the wellbore pressure to a minimum of 110 psi. In the case of buildup, as long as bottom hO'le pressure is less than formation pressure, fluid influx into the well after close in will continue. The bottom hole pressure increases due to phase redistribution and increase in the fluid column height. The redistribution of fluids in the wellbore will cause distortion for true pressure buitdup plots. As a result of this "after flow", the extrapolation of pressure b,uildup may be conservative to the tune of 100 psi. A, production: rate of 20-25 BOPD could be achieved as seen by the test. If the well p:roduced six barrels of liquids when the bottom hole pressure was reduced to 110 psia from 420 psia for 12 hours and 50 percent of the liquid was oil, that is six BOPO. With pumping reducing bottom hole pressure to 100 psia, the well would flow at a higher rate, boosting it to as high as 20 BOPO--maybe to 25 BOPD. :<r~ ~ ,~' ~',~ t<tt ~. . ~...\i"" .~ ~"''''''''' f'"',,1.........,..,.,,~..., (' r::as c~;ns" ,\.~I ':, ',',J. i~:') f~nCllG I atl~ With the high ViSC!ty of the fluids produced, be achieved earliest in the well's production viscosity of the fluid would act as a brake beyond the wellbore, decreas i ng flow rates. e maximum production would life.

A.P 1 ç 1°1'";0 L ) J::)ul) Alaska Oll & Gas Cons. Commission Anchorage Dear Mr. Chatterton: Enclosed is an applications by the North Slope Borough to plug and abandon well SB #20 in the South Barrow Gas Fields Pool Rules Area. This work continues the North Slope Borough's effort to improve operational efficiency in the Barrow Gas Fields, and to eliminate conditions which could potentially pose safety problems. Well #20 was drilled by the Husky oil NPR Operations Inc. as prime contractor for the USGS, ONPRA, U. S. Department of the interior. Spudded on April 4, 1980, the primary objective of this well was to delineate and develop gas reserves in the Barrow Sandstone on the southern flank of the East Barrow Field structure. A secondary objective was to evaluate several thin Lower Cretaceous sands within the Pebble Shale that wireline logs showed to be hydrocarbon bearing in other East Barrow wells. The well reached TO of 2356' on April 24, 1980. A series of production tests (Attached) indicated that the Barrow Sandstone had suffered sever and irreversible formation damage and would never more than a marginal gas producer. The well was plugged back to 1780' and several Lower Cretaceous sands wi thin the Pebble Shale evaluated. These tests produced gas-cut oil and mud. One engineering report speculated that pumping the well might yield maximum production rate of 20 - 25 BOPD. Following Lower Cretaceous testing, SB #20 was shut-in and suspended as an "oil" well. This well has never contributed to East Field production, and given declining field pressure, 51% depletion and water encroachment occurring since 1980, it is a reasonable assumption that SB #20 has no current or future value to the North Slope Borough other than for salvage of materials.

The reservoir produced mainly water and oil, not gas. 2. Temperatures of the producing zones, 1556-1574' and 1629-1639', were approximately 40°F. 3. Initial reservoir pressure CPt) was at least 436 psia. 4. There. was fluid influx into the wellbore and redistribution of these fluids within the wellbore. 5. The well would produce at a maximum rate of approximately 20-25 BOPD. DISCUSSION A standard flow after flow production test was attempted as suggested by H. J. G ruyand Associates. This test was impossible to carry out as planned due t.o rapid decline in pressu re and flow rates. Fluid flow into the wellbore was slow due to the high viscosities at low temperatu reo The pressure buildup plot indicates that fluids entered the wellbore and redistributed within the fluid column. If the only gas produced from South Barrow No. 20 was that which was injected from, Well No. 19, a wellbore to formation pressure differential of 330 psi may have been created. This pressure difference was created by the pressure drawdown during flow, reducing the wellbore pressure to a min imum of 11 0 psi. I n the case of bu i Idup, as long as bottom hO'le pressure is less than formation pressure, fluid influx into the well after close in will continue. The bottom hole pressure increases due to phase redistribution and increase in the fluid column height. The redistribution of fluids in the wellbore will cause distortion for true pressure buildup plots. As a result of this "after flow", the extrapolation of pressure b,uildup may be conservative to the tune of 100 psi. A, production. rate of 20-25 BOPD could be achieved as seen by the test. If the well p:roduced six barrels of liquids when the bottom hole pressure was reduced to 110 psia from 420 psia for 12 hours and 50 percent of the liquid was oil, that is six BOPD. With pumping reducing bottom hole pressure to 100 psia, the well would flow at a higher rate, boosting it to as high as 20 BOPD--maybe to 25 BOPD.

Box 709 Barrow, AK 99723 Re: Suspended Wells South Barrow No. 17 (Gas Well) and South Barrow No. 20 (Oil Well) Dear Mr. Young: A review of our records shows that the above referenced -, wells are suspended. Both wells are equipped with tubing. Well No. 17 has a retainer set at 2048' MD above perforations at 2101' to 2127' MD. Well No. 20 has perforations at 1556' to 1574' MD and 1629' to 1639' MD open to the well bore. Section 110 (a) of the regulations states the Commission will, in its discretion, approve the suspension of a well if the well is· capable of producing hydrocarbons in paying quantities or is reasonably demonstrated to have future value as a service well. Section 105(e} states that n[e]ach well to be abandoned or suspended must be plugged...to prevent the movement of fluid either into or between freshwater and hydrocarbon sources and to prevent all other fluid migration within the well bore." In compliance with Section 170(a} of the regulations, U[t]he location of an abandoned well onshore or upon a historically stable island must be cleared within one year follow~ng well abandonment...." Section 170(b) provides the means for an extension of time if a valid reason exists, and the wellbore is properly plugged. We are., therefore, requesting that you submit Form 10-403, Application for SundL~ Approval, for a one-year extension of suspended St4tus for the above referenced wells, together with justifiCAtion for keeping the wells in suspended status. Please call H?-old J. Hedlund at (907) 279-1433 if you have any questions.

The well was spudded April 7, 1980, at 6:00 a.m. A 12-1/4" hole was drilled to 1500'; the hole was then surveyed, and logged with DIL/SFL/GR/SP and BHC-Sonic/GR/TTI. Thirty-five joints of 9-5/8", 53.5#, S-95 Buttress casing were run to 1490' and cemented with 1,300 sacks of permafrost cement mixed at 14.9 ppg. A float collar and nine centralizers were run on the casing. A CaC12 mud system was built while waiting on cement, and for the blowout-preventer stack to be nippled up. The purpose in converting to a calcium-chloride based mud system was to inhibit the fresh water induced "swelling" of montmorillonitic clays, which had been proved to exist in the Barrow sandstones and in the Sag River Sandstone from water susceptibility tests that had been conducted on core samples taken from South Barrow Nos. 12 and 13. The blowout-preventer stack and the wellhead were tested. The Hydril element had to be replaced. After installing the wear bushing, the hole was reamed from 40' to 550' to remove frozen drilling mud. The casing was tested to 1,500 psi. The float collar, shoe, and ten feet of formation were drilled to 1510'. The formation was then tested to 0.61 psi/ft. equivalent gradient. ...... - An 8-1/2" hole was drilled to 2140', and conditioned for logs. Logs were run as follows: DLL/GR/SP/MSFL; BHC-Sonic/GR/TTI; FDC/CNL/GR/CAL. Fifty-five joints of 7", 38#, S-95 Buttress casing were run after the hole had been conditioned and the drill collars laid down. The casing shoe was landed at 2127', with the float collar at 2090' and FOs at 1297' and 1217'. Circulation was lost prior to cementing the casing. The casing was cemented with 80 sacks of Class "G" cement containing 2% CaC12 and 2% CFR-2 mixed at a slurry weight of 15.8 ppg, with very slight returns. The lower FO at 1297' was opened, a RTTS packer set, and the 7" x 9-5/8" annulus circulated. The FO was closed, the blowout preventer nippled down, and the casing landed. The packoff and tubing head were installed and tested to 3,000 psi. The blowout preventer was nippled up, tested and the wear bushing installed. Both FO's were opened, circulated, closed and tested to 2,000 psi. '- ~ Preparations were made to Arctic Pack the 7" x 9-5/8" annulus. The lower FO was reopened, an injection rate of 3.4 B PM at 350 pSI established, and 60 sacks of 15.0 ppg Permafrost cement down-squeezed through it. The cement was displaced with a barrel of water and 6.5 ba rrels of mud. The packer was released and the FO closed and tested to 2,000 psi. The original mix of Arctic Pack was found to be contaminated with 36% water, and it was remixed. The 7" x 9-5/8" annulus was then displaced with Arctic Pack through the FO at 1217' to the surface. The FO was closed and tested to 2,000 psi. - - Drilling ahead continued. The shoe was drilled out to 2150' and the formation tested to a 0.61 equivalent gradient with no leak off. The 5-5/8" hole was drilled to 2356' with the following cores cut: Core No.1, 2247' to 2269', 20.2' recovered; Core No.2, 2269' to 2299', 29' recovered; ~ 2 ~ Core No.3, 2299' to 2314', 14.9' recovered. Ran in hole for Drill-Stem Test No.1. Open hole Drill-Stem Test No. 1 was conducted on the way down in the interval 2127' to 2314' with no water cushion. Results were as follows: 1st FP (120 minutes): IHP 1,163 psi, opened tool with strong blow, decreased to weak blow in 20 minutes through 1" surface choke, GTS in 60 minutes. IFP 181 psi, shut in for 240 minutes, ¡SIP 909 psi. (gauge No. 134 @ 2139'; field report). 2nd FP (480 minutes): Opened with strong blow, stabilized flow rate through 1/8" choke of 12 MCFPD with 17 psi SFP, FFP 206-289 psi, shut in for 900 minutes, FSIP 958 psi, FHP 1,163 psi (gauge No. 134 @ 2139'; field report). Recovered 2.6 barrels of slightly gas-cut mud with trace of oil. Resumed drilling to 2356' (total depth). Schlumberger logs were run at total depth as follows: DII/G R/S P; FDC/CN L/G R/CAL; BHC-Sonic/G R; MLL/GR. A CBL/VD/CCL log was also run. It showed cement only as high as the top of the Lower Barrow sandstone suggesting possible breakdown of the reservoir during the initial cementing of the 7" casing. After logging, a decision was made to plug back and production test the Barrow sandstones. Plug No.1, 50 sacks of 15.8 ppg Class "G" cement was spotted from 2343' to 2025' in the 7" casing. Ran in hole and tagged cement plug at 2080', cleaned out to 2100', and made preparations to recement across the' sands behind the 7" casing to insure isolation of the test zones. An E-Z drill retainer was set at 2095', the casing tested to 2,000 psi, and four perforations shot at 1950'. A second E-Z drill retainer was set at 1930' and tested to 2,000 psi. An injection rate of 3 BPM at 1,000 psi was established, and 10 barrels of water followed by 35 sacks of 15.8 ppg Class "G" cement were pumped. An additional 25 sacks of cement were mixed and displaced at 1-1/2 BPM at 500 psi. Procedures for Production Test No. 1 of the Barrow sandstones were started. The lubricator was rigged up and tested to 500 psi. The sands were perforated at four shots per foot from 1994' to 2046' and 2064' to 2082'. Two and seven-eights inch tubing was run and landed at 2083' (69 joints, N-80, 6.5#). Ten centralizers were spaced out on the tubing and 1/4" alcohol injection lines run in on it at depths of 1200' and 1900'. The blowout-preventer was nippled down, the test tree nippled up and tested, and the mud displaced with 9.2 ppg CaC12 water. Initial attempts to rock the well in with nitrogen failed. The well broke down with 400 to 600 psi and CaC12 water. Further attempts to bring the well in were unsuccessful, and the test was aborted. The intervals 1994-2046' and 2064-2082' were reperforated at 1994-2046' and 2064-2079', and retested (Production Test No.2). Seven barrels of Halliburton MCA was poured down the tubing, displaced with CaC12 water, 3 - --/ "-" -- and squeezed into the test zones. Gas from Barrow Well No. 19 was used to clean up Barrow Well No. 20, and the test was conducted. Flow through a 1-1/2" choke was 1.31 MMCFGPD, with a maximum flowing wellhead tubing pressure of 30 psi. Bottom-hole temperature and pressure were recorded with a Hewlett- Packa rd recorder as follows: initial bottom-hole temperature 34.7°F; final bottom-hole temperature 37.2°F; maximum bottom pressure 786 psi. - ~ The well was killed and the Lower Barrow sandstone was squeezed with 48 barrels of Halliburton FEA acid, in an attempt to improve production. The acid was injected at a rate of 1/3 barrels per minute at 350 psi to two barrels per minute at 450 psi. Isolation was lost between the Upper and Lower Barrow sandstones during the acid squeeze, and it appeared that the acid was not squeezed into the desired zones. - The well was again blown clean with gas from Barrow Well No. 19 and flowed. Maximum rate was 1.3 MMCFG PD with approximately 1 barrel of water per minute at a flowing wellhead tubing pressure of 30 psi. After two hours of flow, the well was shut in, and a 4-point flow test conducted. Results are summarized as follows: ....... - Final Final Final Flowing Flowing Flowing Surface Surface Pressu re Annulus Tubing Th rough Choke Pressure Pressu re Flow Prover Rate 1/16 600 psi 500 psi 480 psi 40 MCFPD 3/32 580 psi 450 ps i 450 ps i 100 MCFPD 1/8 550 psi 365 ps i 355 psi 100 MCFPD 3/16 545 psi 330 psi 290 ps i Water to Su rface The well was shut in, and a maximum bottom-hole pressure of 786 psi was recorded with a Hewlett-Packard down hole recorder. - After reviewing test results, it was decided to plug back across the Barrow sandstones and test the higher "Pebble Shale" sands. It must be noted that results from Production Test No. 2 suggests that irreversible formation damage occurred to the Lower Barrow sandstone during the initial cementing of the 7" casing. Wireline log analysis indicates that much better production rates should have been obtained from these sandstones. - Preparations were made to plug-back to the "Pebble Shale" sandstones and isolate the two zones. A retainer was set at 1904', and the perforations in the Barrow sandstones were squeezed with 100 sacks of 15.8 ppg Class IIGII cement. Four perforations were shot at 1780', a retainer set at 1749', and 20 sacks of 14.8 ppg Permafrost cement squeezed away. - "-' The "Pebble Shalell sand zones from 1629' to 1639', and from 1556' to 1574' were perforated at four shots per foot for Production Test No.3. Two and seven-eights inch tubing was run and landed at 1644'. The test is summarized as follows: - 4 - Hole full of CaC12 water. Opened well with no flow, unloaded well with gas from Barrow No. 19, maximum FWHP 170 psi declining to 0 psi at end of test, FSIBHP 193 psi, swabbed total recovery of approximately 21 barrels of gas-cut oil and mud. An engineering production report speculated that a maximum producing rate, by pumping, of 20 BOPD, maybe 25 BOPD, might be attained. At the conclusion of the test, the well was shut-in, and officially designated an "oil well", although the small amount of oil recovered, the high viscosity of the oil at the low formation temperature (approximately 40° as reported on production engineering report "Pebble Shale Sands Well Test"), and the effect the high viscosity flow would have in reducing the formation pressure away from the wellbore, casts considerable doubt on the validity of the designation of "oil well". The rig was released May 10, 1980 at 6:00 a.m. and then moved to the South Barrow No. 15 location. 5 """'" ",-. - - Fonn P-331 C (May 11163) "'-" UNITED STATES DEPARTMENT OF THE INTERIOR GEOL.OGICAL.

Every effort was made to minimize weight and grade changes 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: """" - ~ MINIMUM PRESSURE YIELD STRENGTH REQU I REMENT (PSI) (PS I) SIZE(1) WEIGHT MIN. MAX.

All pipe that is 13-3/8" 00 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.@-50°F. 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. .~ - 34 3. Inspect at mill using Tuboscope's Amalog IY 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 thread p rotecto rs . 5. Install closed-end type thread protectors. Plastic plugs can be used to secu re 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 "Y" notching or metal stenciling on pipe body or collars. Casing for South Barrow Well No. 20 was programmed as follows: "13-3/8" conductor at ±110'; 9-5/8" at ±1500'; 7" at ±2100'; 2-7/8" production tubing to the top of the producing zone should the well be completed. Temperatures in the reservoirs ,in the East Barrow gas field range from 50-55°F due to permafrost depth. Because of this, production completions have been modified to prevent downhole freeze-off of the wells due to hydrate formation. Husky's usual procedure has been to suspend a 2-7/8" string of production tubing in the 7" casing to the top of the producing zone. The well is then produced through the 7" x 2-7/8" annulus. The lesser pressure drop in the larger annulus helps to prevent the formation of hydrates dow·nhole. The 2-7/8" tubing is then used to inject alcohol (blown down the well) when freeze-off does occur". In South Barrow No. 20, a string of 2-7/8" production tubing was run to 1644' (just below the bottom perforations at 1639') when the well was completed in the "Pebble Shale" sands. - ~--- Casing actually run in the well was 13-3/8" at 100'; 9-5/8" at 1490', and 7" at 2127'. - - 35 - FIELD -- ------ - East Barrow Gas Field SUMMAHY or PAGE MEASUREMENTS NO.OF JOINTS PAGE 1 PAGE 2 PAGE J PAGE 4 PAGE 5 W PAGE 6 0'\ - -.----.--, ,--.-.

It is a stable, highly víscous fluid which will not freeze and collapse casing set in permafrost zones. Its unique gelling characteristics exhibit excellent thermal properties (heat transfer coefficient of approximately 0.1 BTU per hour per square feet per degree F at 32°F). Composition of Baroid Arctic Casing Pack used is as follows for each 100 barrels mixed: Diesel Water Salt EZ Mul Gel Tone Ba rite 82.0 ba rrels 5.0 barrels 60.0 ppb per barrel of water 12.5 ppb 50.0 ppb 1 03 . 0 p p b The 9-5/8" x 7" annulus in South Barrow No. 20 was left full of Arctic Pack from 1297' to the surface when the well was completed. The annulus was displaced with Arctic Pack through the FO at 1217' immediately after the 7" casing was run in anticipation of completing the well as a gas producer in the Barrow sandstones. When the decision was made to squeeze the Barrow sandstones and complete in the "Pebble Shale" sands, the Arctic Pack was left in place. 48 - ~~ RIG INVENTORY Draw Works ... - National T-20, single drum grooved for 1" wireline with 15" double hydromatic brake, automatic breakout and make up catheads, driven by one set GMC diesel twin 671 engines, 300 HP, through Allison torque converter, all mounted on single skid.

GEOLOG IC SUMMARY I NTRODUCT I·ON The South Barrow No. 20 well is located in the NE 1/4 of protracted Sectión 26, . T22N, R17W, Umiat Meridian, North Slope Borough, Alaska. The surveyor's plat locates the well 1980' FNL and 1600' FEL of the section (see Figures· 1 and 2). The well was drilled in early 1980 in order to further delineate and develop the East Barrow Gas Field, with the Lower Barrow sandstone as the primary objective. Secondary objectives were to test the productive potential of the Upper Barrow sandstone, Sag River Sandstone, and to evaluate, if· possible, several thin "Pebble Shale"· sandstones which appeared to contain hydrocarbons. South Barrow No. 20 was spudded on April 7, 1980 May 10, 1980 as a reported shut-in oil well in two "Pebble Shale", although test results and duration necessarily justify the "oil-well" designation. and completed on sandstones of the certainly do not! I n each of the South Barrow wells drilled after No. 13, an inhibitive mud system, çontaining calcium chloride, was used below the intermediate casing (commonly 9-5/8" to about 1,500 feet). This was done to minimize damage to potential reservoirs caused by swelling clays, which are present in the Barrow sandstones and the Sag River Sandstone (determined by water-susceptibility tests on cores from the South Barrow Nos. 12 and 13). The high concentrations of calcium chloride used below the intermediate casing necessitated running a dual laterolog, as the high calcium and chloride ion concentration in the mud adversely affects the measurement of conductivity by the dual induction log. The dual induction log was run In the upper part of each well where fresh-water mud was used. PRE-DRILLING PROGNOSIS The South Barrow No. 20 was intended as a development gas well in the Lower Barrow sandstone. The sandstone was expected to be similar to that penetrated in the South Barrow No. 12. Approximately 20-30' of porous sandstone was anticipated. Secondary objectives of the well were the Upper Ba rrow sandstone and the Sag River Sandstone. Additionally, evaluation of several thin sandstones of the "Pebble Shale", if developed as in the No. 12 well, was planned 'if conditions appeared favorable. POST -DR I LlI NG SUMMARY The principal objective of South Barrow No. 20, the Lower Barrow sandstone, had 20 feet of clean, porous sandstone developed. This was consistent with the predicted 20-30 feet. Since the sandstone had good shows, was well situated structu rally, and had good porosity, there was every reason to expect better-than-average gas production from the Lower Barrow. Although the well achieved a maximum of 1.3 MMCFGPD and one barrel of water per minute on Production Test No.2, electdc log. . . I I I I I I I I I I I I I I I I I I I computation and sample analysis indicated that production should have been better. It has been concluded that the sandstone was damaged by cement entry when the 7" casing was cemented. The Sag River Sandstone, although bleeding oil from cores, was much too tight, as demonstrated both from core and log analysis, to yield significant amounts of fluid. This conclusion was proved by the negative results of a drill-stem test of the sandstone.. Finally, the recovery of gas-cut oil and mud from two sandstones in the "Pebble Shale", has led to South Barrow No. 20 being officially termed a shut-in oil well, although the amount of oil recovered, plus associated temperature and production problems, casts considerable doubt on the well's classification as an "oil well". 2 J ~ ------------------- ""'........ ."..

NELSON, JR. REVISED BY: GORDON W. LEGG INTRODUCTION The South Barrow No. 20 well was drilled in early 1980 in order to further delineate and develop the East Barrow Gas Field. A location to the south of South Barrow No. 12 had been chosen to test the hypothesis that the Lower Barrow sandstone would improve in reservoir quality in a southward direction. Additionally, South Barrow No. 20 was to further evaluate the potential of the Upper Barrow sandstone and investigate the possible oil potential of the Sag River Sandstone. Testing was anticipated for several thin sandstones in the "Pebble Shale", which had contained good shows in previous wells and appeared to be hydrocarbon-bearing from log analysis. . . The major objective, a producible gas well, was not realized because the Lower Barrow sandstone was apparently irreversibly damaged during the cementing of the seven inch casing at 2127'. Two production tests were performed th rough perforations of the Upper and Lower Barrow sandstones with a maximum recovery of 1.3 MMCFGPD and one barrel of water per minute (page 11 and Appendix D). Other objectives fulfilled were the coring and testing of the Sag River Sandstone (12 MCFGPD and slightly gas-cut mud with trace of oil) and testing two sandstones in the "Pebble Shale" with a recovery of gas-cut oil and mud.

I I I I I I I I I I I I I I I I I I I CRETACEOUS Torok Formation: 100-1313' Rocks representing the Torok Formation in South Barrow Well No. 20 are almost entirely claystones, which are typically soft, silty and occasionally sandy. There are thin siltstones and sandstones, with the sandstones generally absent above a depth of 750'. The sandstones are light gray, very fine to fine grained, silty and argillaceous, and frequently carbonaceous. The siltstones are gray, very argillaceous, typically sandy, and carbonaceous. A few very thin beds of coal are present from 750' to 950'. There are rare traces of pyrite and shell fragments. There were increases in 1230-1300' . no visible shows the chromatograph in the samples, gas readings, and only a few slight mostly in the interval "Pebble Shale": 1313-1733' lithologically, the "Pebble Shale" is easily distinguishable from the overlying Torok by the presence of well rounded, frosted to polished quartz grains, which are "floating" in the shale matrix. The shale is very dark gray to black in the upper part, and it is also silty, finely micaceous and organic, but grades downward to a dark gray, carbonaceous, silty shale, which is somewhat less organic than the upper section. The upper part of the "Pebble Shale", about 60', is also quite distinctive because of the strong increase in the gamma-ray response. Below a depth of 1500', the "Pebble Shale" becomes very silty to sandy. In this section are two relatively clean sandstones, which contained good, visual oil staining, and also registered fair gas shows on the chromatograph. The first sandstone, from 1564' to 1573' (DLL), is described as being "salt and pepper", gray and brown stained, fine to medium grained, with scattered coarse grains and having fluorescence and cut. The second sandstone, from 1625' to 1636' (DLL), is described as being "salt and pepper" gray, with brown stain, very fine to fine grained, with scattered coarse grains and friable, also with fluorescence and cut. Both sandstones were production tested after the well had reached total depth (see discussion under "Hydrocarbon Shows and Tests"; also, test data in Appendix D). The lowermost part of the "Pebble Shale" (approximately 100' thick) is predominantly siltstone, which is medium gray to brown, argillaceous, partly sandy and calcareous, with coarse grains and granules of quartz and dark chert. This 100' unit contains a "basal" sandstone, about 12' thick, which is "salt and pepper" gray, slightly conglomeratic, argillaceous, and slightly "dirtier" than the sandstones above. There was a reported good yellow fluorescence and milky-yellow cut fluorescence. 7 I I I I I I I I I I I I I I I I I I I . . JURASSIC Kingak Formation: 1733-2130' The upper 250' of the Kingak Formation is composed of shale, which is light to dark gray and gray-brown, soft to firm, and is considerably less silty than the overlying "Pebble Shale" . The shale is frequently carbonaceous, and is bentonitic in part. At 1980', the shale grades downward into a sandy facies,' which is represented by the Upper and Lower Barrow sandstones. From the bottom of the Lower Barrow sandstone at 2082' to the Triassic top at 2130', the Kingak Formation is represented by interbedded siltstone and shale. These rocks are medium gray-brown, partially micaceous and carbonaceous, sandy, and pyritic. Upper Barrow sandstone: 1980-2043' The Upper Barrow sandstone is light gray, very fine grained, moderately clay-filled, slightly calcareous, silty, glauconitic and friable to hard. Thß rock has poor porosity, !some brown staining, gold fluorescence, and bright milky-white cut fluorescence. Electrical-log characteristics indicate the zone is shaly and tight, although a 1,600-1 ,900-unit gas reading was recorded in the interval 2025-2060' on the mud log. Neither conventional nor sidewall cores were taken in the Upper Barrow sandstone. Separating the Upper Barrow from the Lower Barrow sandstone is a 19' section of Kingak sandstone, similar to the Upper Barrow, which grades to siltstone. Although not noted in the samples of this well, there is usually a thin 1-2' shale capping the Lower Barrow sandstone. This shale can be picked on the drilling-time logs and is indicated on the gamma-ray log of this well at 2060-2062' (DLL). Lower Barrow sandstone: 2062-208:r The Lower Barrow sandstone, the principal producing zone in the East Barrow Gas Field, was encountered in the interval from 2062-2082' (DLL). The sandstone is medium gray to brown, very fine to fine grained, and friable. This sandstone is relatively cleaner than that in the Upper Barrow. Glauconite pellets and shell fragments are scattered in the sandstone. The rock has fair porosity, dull fluorescence, and bright yellow cut fluorescence. The sandstone registered a gas show of 1,800 units when the section was penetrated. No sidewall cores or conventional cores were taken in the interval. Log calculations by Armour Kan~ give an average porosity of 24% and a water saturation of 36% for the interval 2068-2074'. No drill-stem test was taken in this interval, but a later production test, co-mingled with the Upper Barrow sandstone, recovered gas at a final rate of 1.3 MMCFPD. Details of this test and other tests are discussed under "Hydrocarbon Shows and Tests". 8 . . I I I I I I I I I I I I I I I I I I I TRIASSIC Undifferentiated: 2130-2240' Triassic rocks were first penetrated at a depth of 2130'. This depth was obtained from log correlations with South Barrow No. 14 well, where paleontological determinations were available. No paleontological analysis was performed on South Barrow No. 20. The portion of the Triassic above the Sag River Sandstone (2130-2240'), consists of medium to dark gray shale and some argillaceous siltstone. The shale and siltstone are firm, slightly carbonaceous, and have scattered concentrations of dark to medium green glauconite(?) pellets. Sag River Sandstone: 2240-2314' The Sag River Sandstone consists of white to tan, very fine grained, hard, glauconitic sandstone in the uppermost part. Porosity at the top is very low. It grades downward to fine grainéd, friable sandstone with dark brown stain (dead oil), dull orange fluorescence, and immediate bright yellow cut. At a depth of 2247', a coring program was initiated, resulting in three cores being obtained at 2247-2269' (cut 22', recovered 20.2'); 2269-2299' (cut 30', recovered 29'); and 2299-2314' (cut 15', recovered 14.9'). All three cores contained Sag River Sandstone, with Core No. 3 additionally penetrating about 0.2' of argillite basement. A generalized core description for each core is as follows: Core No. 1 Core No.2 Core No.3 Sandstone: medium gray to green, calcareous, clay-filled; tight, bleeding heavy oil, strong odor. glauconitic, dark brown Sandstone: medium green to brown, very fine grained, with occasional coarse grained and shelly zones, glauconitic, calcareous; tight, bleeding dark brown heavy oil throughout, strong odor, dull gold fluorescence, bright greenish-yellow cut fluorescence. Sandstone: medium brown to green, very fine grained, some coarse graíned, glauconitic, hard, very calcareous; shells and. fragments common; tight, bleeding heavy brown on from pores and fractures; bottom 0.2' is 'argillite, bright green at contact, then dark gray, hard; . micromicaceous; dips of approximately 45°. The interval from 2127-2314' was drill-stem tested, with a recovery of gas-to-surface after one hour of the first flow period at a rate too small to measure. Flow rate stabilized at 12 MCFGPD in second flow period. Recovery in the drill pipe was 2.6 barrels of slightly gas-cut mud with a trace of oil at the top of the testing tool. . The disappointing recovery, plus the poor formation pressures, confirrJ:led that the Sag River Sandstone is too tight to be a potential reservoir at this location. 9 I I I I I I I I I I I I I I I I I I I . . PRE-MISSISSIPPIAN Argillite: 2314-2356' The interval from 2314' to the total depth of 2356' is composed of dark gray, micromicaceous, pyritic, hard argillite with some quartz veins. A description of the top of the argillite section was given above in Core No.3. HYDROCARBON SHOWS AND TESTS The first shows of any significance occurred in several thin sandstones in the "Pebble Shale". The fi rst of these sandstones at 1564-1573' had a gas reading of 300 units and contained brown oil stain with a gold fluorescence . and yielded a milky-yellow cut. The porosity calculated by the log analyst, Armour Kane, was an average of 17%, and the water saturation was 27%. The second sandstone, at 1625-1636', had a gas reading of 250 units, appeared to be friable and porous in the samples, and had brown oil stain, gold fluorescence and milky-yellow cut. Calculated porosity and water satu ration was 21% and 12.5%, respectively. Another sandstone, 1704-1710', had a 260-unit gas reading and contained good fluorescence and cut. Sample observation and electric-log analysis indicate that the sandstone is shaly and tight. A production test (Test No.3) with a perforated interval of 1556-1574' and 1629-1639' in the 7" casing, was conduded after drilling was terminated. This test recovered a total of 21 barrels of fluid (see Appendix D for Production Test No. 3 and Summary of Testing Procedures, "Pebble Shale" sands). This fluid was reported as gas-cut oil and mud, without any stated ratio of oil/mud. In the Production Test No.3 write-up, conclusion No. 1 states that: "The reservoir produced mainly water and oil, not gas." Under the "Discussion" in this report, the engineer predicts that by pumping, the well might be capable of producing 20-25 BOPD, with that rate being attained only in the earliest portion of the well's productive life, and then declining as the high viscosity of the fluid would act as a brake on the reservoir pressure beyond the wellbore. Shows were encountered in both the Upper Barrow sandstone (1980-2043') and in the Lower Barrow sandstone (2062-2082'). The Upper Barrow registered 1,900 units of gas, and the Lower Barrow registered 1,800 units of gas. Both sandstones contained good visual staining, fluorescence, and cut. The Upper Barrow sandstone is very shaly, both in the samples and from an examination of the gamma- ray log. Log calculations showed a density porosity of 15-16% and a water satu ration of 40-45%. The Lower Barrow sandstone was quite clean. The calculated porosity was 24%, with a calculated water saturation of 36%. The reservoir quality of the sandstone should have been very good, based on sample analysis, and interpretation of all electric-log parameters. A problem developed when the discovery was made that cement from the cementing operation on the 7" casi ng had appa rently not risen above the Lower Barrow sandstone. The inescapable conclusion is that the Lower 10 . . I I I I I I I I I I I I I I I I I I I Barrow was severely damaged by cement 'being squeezed into the zone. This is the most likely explanation for' the later poor productive performance from what should have been a very good gas-producing sandstone. Two production tests were conducted after drilling was completed by perforating both the Upper and Lower Barrow sandstones. These zones were tested together, instead of as separate units, when it was discovered there was no cement behind the casing aboye the Lower Barrow sandstone. A block squeeze was performed above the Upper Barrow sandstone by perforating the casing from 1950-1951' and injecting cement. Since only 19 feet separated the Upper and Lower Barrow sandstones, a decision was made n.ot to block squeeze for isolation of the two· sandstones and risk fu rther formation damage. Production Test No. 1 (1994-2046' and 2064-2082') was unsuccessful when the well was unable to unload the calcium-chloride mud from the hole. The test was aborted, and the interval was reperforated for Production Test No.2 (1994-2046' and 2064-2079'). This test achieved a maximum rate of 1.3 MMCFGPD with 1 barrel of water/minute on a 1.5" choke and a flowing tubing pressure of 30 psi after being acidized (see Appendix D for details) . The lowermost zone of show in the South Barrow No. 20 was in the Sag River Sandstone, which was encountered at 2240'. The Sag River Sandstone was continuously cored from 7 feet below its top through the base of the interval at 2314'. The cores were stained with dark brown heavy oil, and were bleeding oil throughout, indicating that the sandstone was tight. No increase in gas was noted from the mud log. The sandstone was shaly and well cemented with calcite. Log calculated porosities ranged from 4-16%. Drill-Stem Test No.1, conducted from the base of the 7" casing at 2127' to 2314' (total depth at .time of testing), confirmed the tight, non-productive nature of the Sag River Sandstone, by getting gas to the su rface after one hou r into the fi rst flow period. The gas flow was at a rate too small to measure. Flow rate stabilized at 12 MCFGPD with 17 psi FP in final flow period. Recovery of fluid in the drill-pipe was 2.6 barrels of slightly gas-cut mud, with a trace of oil. CONCLUSIONS The South Barrow No. 20 failed to achiev.e its major objective, when the Lower Barrow sandstone was apparently severely damaged by the cementing job on the 7" casing. The productio,n test of both the shaly, tight Upper Barrow and the damaged Lower Barrow (co-mingled), failed to yield gas at a production rate and pressure high en'ough to put the well into production. A secondary objective, coring and testing the Sag River Sandstone for its potential as a hydrocarbon producer, was achieved, but yielded negative results, since the zone was too tight to give up significant amounts of fluid. 11 I I I I I I I I I I I I I I I I I I :1 . . Finally, the secondary objective of evaluating the productive potential of the "Pebble Shale" sandstones was achieved by obtaining a small amount of gas-cut oil and mud (estimated at 21 barrels) on a production test. The necessity of having to successively "gas-lift" the fluid from these sandstones by injecting gas from South Barrow No. 19, the low pour point of the oil (-49°F), and the low temperatures (39.4°F at 1635'), places a great deal of doubt on whether or not South Barrow No. 20 can be justifiably termed an "oil-well". 12 I I I I I I I I I I I I I I I I I I I . .

I I I I I I I I I I I I I I I I I I I PRODUCTION TEST NO.3 "Pebble Shale" sands CONCLUSIONS 1. The reservoi r produced main Iy water and oil, not gas. 2. Temperatures of the producing zones, 1556-1574' and 1629-1639', were approximately 40°F. 3. Initial reservoir pressure CPt) was at least 436 psia. 4. There was fluid influx into the wellbore and redistribution of these fluids within the wellbore. 5. The well would produce at a maximum rate of approximately 20-25 BOPD. DISCUSSION A standard flow after flow production test was attempted as suggested by H. J. Gruy and Associates. This test was impossible to carry out as planned due to rapid decline in pressure and flow rates. Fluid flow into the wellbore was slow due to the high viscosities at low temperatu reo The pressure buildup plot indicates that fluids entered the wellbore and redistributed within the fluid column. If the only gas produced from South Barrow No. 20 was that which was injected from Well No. 19, a wellbore to formation pressure differential of 330 psi may have been created. This pressure difference was created by the pressu re drawdown du ri ng flow, reducing the wellbore pressu re to a minimum of 110 psi. In the case of buildup, as long as bottom hole pressure is less than formation pressure, fluid influx into the well after close in will continue. The bottom hole pressure increases due to phase redistribution and increase in the fluid column height. T.he redistribution of fluids in the well bore will cause distortion for true pressu re buildup plots. As a result of this "after flow", the extrapolation of pressure buildup may be conservative to the tune of 100 psi. . A production rate of 20-25 BOPD could be achieved as seen by the test. If the well produced six barrels of liquids when the bottom hole pres:sure was reduced to 110 psia from 420 psia for 12 hours and 50 percent of the liquid was oil, that is six BOPD. With pumping reducing bottom hole pressure to 100 psia, the well would flow at a higher rate, boosting it to as high as ·20 BOPD--maybe to 25 BOPD. D-8 I I I I I I I I I I I I I I I I I I I . With the high viscosity of the fluids produced, be achieved earliest in the well's production viscosity of the fluid would act as a brake beyond the wellbore, decreasing flow rates. . maximum production would life. With time the high on the reservoi r pressu re Because of the multiphase production of this well, no other reservoir properties, such as permeability and skin effect, can be evaluated.

Hevi t1¡ Hus.lq oil/N:Æ Operations, Inc. 2525 C Street Anchorage, Ak 99503 Dear Mr. Hni t1a Scl:ùumberger began the second logging run at South Barrow No. 20 at apprœ:imate~ 0500 hours on Apr:il l4, 1980, and completed DLI.,. CNL/FDc am ERC at about 1200 !loura the same day to a total depth of 2130. Log quality was good except for a stic.lq galvanometer on the gamllla ray trom 1734 to 1924 but the interval was traced on from another log. Top of the Upper 3arrov Sand is not too well defined by the gamma ray but appears to be aDout 1980. Top of the Lower Barrow Sand. is 2062. Two zones of interest up the hole, one from 1564 to 1573 and. the other trom 1625 to 16 36 indicate gas saturation from the curve responses of Neutron-Density where the two curves are moving in opposite directions. The apparent neutron porosity is no doubt too high due to shale effects but the curYe. responses definite~ suggest gas. Here, again, the old problem of Rw arises am there are no wet zones for Rwa computations. However, since the SP shows a positive defiection of some 8 HV, R..., should approximate Rme of 0..l27 and is probablJr 0.15. Th:i.s figure was used in computations of both zones resulting in porosity of 17% and Sy ()t 27% in the upper sand. and porosity of 2]$· and Sy of 12-13% in the lower zone. Approximate cross..plot results indicate an invasion diameter ot 20-23 inches. Both sands are shaly but are worthy ot testing. In the Lower Barrow Sand. an interval trom 2068-74 appears gassy with a porosity ot 21% and Sw of 36% using the Rw o! 0.15, while the Upper Barrow appears quite s~, 40-45%, with an average density porosity of 15-16%. 2.uw The third 10Gain~to total depth of 2356 was begun April 23 at 0900 hours and finished DLI., CN!./:DC, EHC and CEI. at 2100 !lours the sa;ne è.ay. Log quality was good except for some skipping and spiking on the SHC and a somewhat questionable caliper on the an.¡':DC. AU. logs were recorded 8 feet shalJ.ow to pipe measurement, casing shoe and lithology log. Top ot the Sag River Sands was found at 2210 and Argillite at 2315. The Sag River Sands are of low porosity from 4% to 16% and appear quite shal7 and probab~ tight with little evidence of hydrocarbon saturation which confirms the disappointing formation test.

This reserve shall not be less than the amount necessary to make a mud volume equal to the calculated capacity of the active downhole and surface mud systems. 11. Blow-Out Prevention Eauipment and Practices Blow-out preventer and control valves must be installed prior to drilling below surface casing. Blow-out prevention equipment shall consist of an annular type and the specified number of ram-type preventers, one of which shall contain a blind ram, as set forth in API RP 53. The pipe rams shall be of proper size to tit the pipe in use.

Testi~ (1) The equipment shall be tested when it is installed, before drilling out after each string of casing is set, not less than once each week while drilling, and following repairs that require disconnecting a pressure seal. Ram-type blow-out preyenters and related control ·equipment shall be tested at the rated working pressure of the stack assembly PI' at 70% of the minimum internal yield pressure of the casing, whichever is the lesser. Annular-type preventers shall be tested at 70% of the rated working pressure. (2) Pipe rams shall be actuated daily and the blind rams shall be actuated each time the drHlpipe is out of the hole. The District Supervisor should be notified prior to the initial and weekly testing procedures so that a Conservation Division representative may witness the test. '."' (3) All well control tests and crew drills shall be rec:orded on the drHlers log and the Cons·ervation Pivision shall be furnished a cooy of the oressure test reDor~ . b. Accumulator Accumulator system shall maintain a pressure capacity reserve at all times to provide for repeated operation ot hydraulic preventers. c. Ram-Tvpe Preventers Ram-type pre venters shall be equipped with extension hand wheels or hydraulic locks. d. Other RQuipment An inside blow-out preventer assembly (back pressure valve) and an essentially full-opening drill-string safety valve in the open position shall be maintained on the rig floor to fit all pipe in the drill string. A kelly cock shall be installed below the swivel, and an essentially full-opening kelly cock of such design ..- ". ,....-.-.... . . .....~ ~'i Page 5 of 6 that it can be run through the blow-out preventers shall be installed at the bottom of the kelly. e. BOP Drills A blow-out prevention: drill shall be conducted weeklv for each drilling crew. f. Certifications All c1rillingpersonnel shall be familiar with the blow-out prevention equipment before starting work on the·well. Supervisory personnel must be trained in well control techniques and their latest well certification for training courses shall be maintained at the well site. 12. MultiDle Zone or Alternate Zone ComDletions >', All multiple or alternate zone completions must be approved in advance. Applications for such approval must be accompanied by: a. electric log of well with separate zones clearly marked. b. diagrammatic sketch of mechanical installation proposed. 13. Oil and Gas Shows .,;: ~ All showings of oil and gas must be evaluated, and if commercial, must be depleted before abandonment (depletion of commercial producing zones is not appícable to present NPR-A exploration drilling program). Any show of oil and gas not completed shall be isolated with cement behind pipe in any producing well, or isolated with cement plugs in any dry hole. All other minerals penetrated will be reported to the District Supervisor, and must be isolated in the same manner as oil and gas shows. 14. General Uses of Form 9-111 This form is to be generally used by the Operator to submit SUBSEQUENT reports of COMPLETED drilling operations that have been described, and approved, in a previously submitted plan.

That is a sub-sea datum of -2078; highest structural point established on L. Barrow sand (well 19) is -1990~ giving a gas column about 88 or 90 feet thick. Analysis of gas produced from well 19 indicated about 12% Nitrogen~ whereas gas from well 17 had less than 1% Nitrogen. Well 12 had about 7% Nitrogen. The meaning of this information is not clear~ but may be related to faulting of the Barrow sand reservoir. Additional information may be forthcoming from the high resolution seismic program of last winter~ and certainly from additional drilling. Reservoir quality of the L. Barrow sand does not seem to vary widely among the 4 wells drilled to date in the East Barrow field. The thick- ness varies only from a miximum of 25 feet to a minimum of 19 feet, with downdip wells having thicker sections. It appears to me that well 16 may have crossed a reverse fault. I sug- gest you look at the Gamma-Sonic~ and see if you think the section 1750-80 might not be repeated at 1930-60. Hopefully the high resolution seismic will also clarify the possible faulting in the 16. H. J. Gruy and Associates have proposed to have some special core analyses performed on cores of L. Barrow sand from well 17. The material will be shipped to Core Lab in Dallas this week. The information will ·serve to increase the accuracy of the reserve estimate of East Barrow which they will prepare in the near future. There may be a variation of a few feet on some logs for formation tops, and some of you may have already called a top at a different depth. If it is close, can we agree to the calls listed here? If you think the difference is important. let me know and we will argue about it and maybe change the call. If the tops listed here seem close enough to you who will be using the logs of these wells, we can probably save arguments and misuñderstandings if most of us. at least, use the same calls in our mapping of the L. Barrow (top and base). Sag River top. and top of Argillite. Incidentally. I am a little confused by the telescoping substructure on Brinkerhoff rig 131; it was evidently 18 feet high on well' 16 (30-12 = 18); 26 feet high on well 17 (33-7 = 26); and 20 feet high on well 19 (30-10 = 20) Does anyone know the reason for this? 2 ~ :::- -- ~ ----- 7U~ < <: ~ . ~ ~ ~ -010...:- ~._---_._~--- ii1Þ ~ 1 . ~ <:::: ~ -.t..aoo · if -23M' . 5B b:¿O . . 1tJ6-ö<14 ......... ... . ..- ::.,.'~".... ...... ...._~-_._-_.__..__. ~. ---~~'" ~. ..~~..~.u___ C- > ==-- .
