The Borough Department of Public Works has researched a history of documents in an effort to demonstrate that wells #12 and #18 were plugged and abandoned. To recap what we have found: • The AOGCC was notified by the Borough of its intent to P&A well #12 on March 10, 1988. The AOGCC provided sundry approval on March 16, 1988 as approval #8-164. The Borough had Halliburton circulate permafrost cement down the annulus to surface. The annulus and bullhead were closed. The wellhead was removed, the pipe cut off below ground level and a dry -hole marker installed. • June 22, 1988: The AOGCC's Doug Amos wrote he was unable to complete inspections on both wells #12 and #18 due to snow cover. He did comment that both marker posts for wells #12 and #18 were in compliance, and provided a location clearance inspection form for both wells. • August 16, 1988. Amos again travelled to Barrow. He wrote the pad was still in need of gravel, the pad lower than the marker post area. On September 22, 1988 Amos wrote that final approval for well #12 was pending the Borough a barrel around a marker, and grade the pad. • October 11, 1988: The Borough notified the AOGCC that the well sites in question to include wells #12 and #18 were graded to AOGCC specifications and photographs were provided. On October 20, 1988 the AOGCC provided final location clearance for well #12. While information for SB 12 was fairly well documented, the Borough during its research was unable to locate significant documentation regarding the history of SB18. The requested form 10-407 Well Completion reports are attached. Please contact me at Joe. Ram irez@north-slope.org, if you have any questions.

That operation may have been conducted after I left the project, so I wouldn't have any backup records related to that particular phase of the project or if I did, the files may have simply been deleted or archived on a drive I don't have access to anymore once the project became inactive. Unfortunately, the back-up and archive systems available to me 30 -years ago weren't nearly as robust as today's cloud -based approaches, so I can't say with any certainty if I ever had any files related to the P&A of SB -18 or not.

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.

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.

I. Supervisor .,(fli!cÔ South Barrow Field FROM: ~r . John H Spaulding, 1 ò(..,.~ 5 Petroleum Inspeçtor ., AU$lust ~1, 2000: I traveled to the Barrow Gas Field to review their records for "proper': Plug and Abandonment procedures on the following wells. South Barrow Test well # 4 pro .100-02(3 : ~: There is no data on any type of P&A. From our records it appears that the well was drilled in 1950 by the U.S. Navy, production was apparently curtailed in 1968. The well still has a coverlwellhouse over it, there is $till wellhead attached. As the accompanying pictures denote the area around the well head is covered in water. I was unable to find anyplace that would show there was a reserve pit. it is quite possible that the reserve pit was removed. I suggest that before writing this well off as P&Nd. that the US Navy be contacted in an effort to find out where cement in the well bore might be. I recommend that this well have the well house removed I the well head removed, the casing blinded off and at a minimum a mound of gravel or dirt placed around the well to keep the water from impacting the casing as well as mitigating a safety hazard. South Bar~ºw # 7 N~B-07DP. PTO 187-075: According to Hallíburton's job log and billing statement this well was P&A'd 3-29- 88, the AOGCC records show the well was removed from production status Bnd P&A'd on 11/17/88. The well has a dry hole marker that appears to be placed in the cement after the well head was removed - no welded cover. From the pump reports it appears that cement was circulated down the production tubing with returns being taken thru the annulus. Once cement was observed at surface the annulus valve was shut in, squeeze pressure was obtained and a volume was placed behind pipe or into the fonnation. Considering the depth of these wells (shallow) this is probably a good cement job, therefore a prettv Qood P&A. , . ~ l I recommend that the well be dug out 3' below original grade, dasings cut off and a welded cover be placed on the casing stub. As these wells are close to town this would mitigate a safety concern of mine with the winter snow machine traffic. ZOO® XVd CO:Zl £00ZI£1/60 y'. ./'" -<., e '------. - "---, . .~ South Barrow # 12. PTD 100.-0.35 and South Barrow # 18. prD 10.0-046: . . These wells were P&A'dat about the same time as well number 7, same contractor and the same procedure was used. Contractor billings were used to obtain this information as well. No. Sundries were applied for or issued for these 3 wells. . As noted in the pictures the casing on well # 12 is tore up some, and it appears that the dry hole marker has been placed in the cement at the top of the casing. There is no evidence of a reserve pit in the area. Well 18 as shown in the pictures, has the same type of surface abandonment, with the exception of the reserve pit area. The reserve pit area has been broached and some of the gravel has been removed.' , I recommend that these three wells be cut off 3" below original grade the casing stubs blinded with a welded cap and a mound of gravel placed over the casing. Fa~ilities While in Barrow I visited the facilities that are currently ·in use. These will be feplac~d .in the near future. The new facilities are on loc~ion but have not been commlssloJled as yet . . ;~ I was particularly interested in the current and future tACT metering $ystems. When at peak usage this meter handles about 6mmcf daily, a relatively small . amount. I am not familiar with the current Rockwell "Electro Corrector' system that is in use, this is a charted turbine meter. Thîs meter is "checked" on a monthly basis and is compared to the Barrow Utilities Sales meter. This meter is calibrated on an annual basis. In the new facilities there are 3 separate runs~ one for each field with a "Daniels" computerized orifice plate meter. These will feed into a 4" line that contains the IIDaniels" LACT meter. The new facilities are quite a step up from where they are today. SLJMMARY (by Blair Wondzell): ' , 1. South Barrow wells 7,12, and 18 appear to be properly plugged but should be cut off at least 3' below original ground level and a marker plate installed. 2. South Barrow well #4 does not appear to be properly plugged; the well house should be removed, downhole plugs installed and casings cut off at least 3' below original ground level and marker plate installed. 3.

Chatterton Alaska Oil & Gas Conservation commission 3001 Porcupine Drive Anchorage, Alaska 99501 April 11, 1988 REFERENCE: P & Application for ,¡!W Dear Mr. Chatterton: Enclosed is an application by the North Slope Borough to plug and abandon well SB #18 in the South Barrow Gas Fields Pool Rules Area (Figure 1). 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 or environmental problems. Historical Overview Well #18 was drilled by the Husky Oil NPR Operations Inc. as prime contractor for the USGS, ONPRA, U. S. Department of the interior. The primary objective of this well was to delineate and develop gas reserves in the Barrow Sandstone along the northeastern flank of a small plugging anticline which defines the East Barrow Gas Field. The well reached TD of 2125' on October 6, 1980. Two production tests were performed. The first flowed gas at the rate of 340 Mcf/day perforated between 2056 - 2074 in the Upper Barrow. The second test evaluated the Lower Barrow between 2056.5 - 2076.5 which resulted in a calculated AOF of 1,650 Mcf/day. The well was completed as illustrated in Figure 2, and eventually connected to the Barrow gas distribution system as a significant producer in the East Barrow Gas Field. With continued depletion of East Barrow reserves, production from this well has decrease, and changed character. RECEIVED 14 1988 Alaska Oil & Gas Cons. Commission Anchorage · . e e A.O.G.C.C. P & A SB #18 Page 2 of 2 04/11/88 At present the well is producing approximately 20 Mcf/day (approximately what is required to operate the associated surface facilities), along with 8 bbls/water and 1 bbl/day oil. The production of both water and oil have established a increasing trend of over the past year which is expected to accelerate with further aquifer encroachment. Current Barrow Gas Field facilities are not able to handle any significant amount of produced fluids. oil is particularly difficult to handle with well designs which produce gas up the annulus, and blow rathole fluids to atmosphere through the production tubing as routine operating procedure. Give the above, we intend to plug and abandon SB #18 as specified in the following operations Plan and attached Application for Sundry Approvals. General Operations Plan To accomplish the abandonment work, we will employ the following plan for SB #18 which has now been successfully employed on three other South Barrow wells: 1. Circulate permafrost cement down 2-7/8" Tbg and up the 2-7/8" x 7" annulus to completely fill the entire hole volume with cement, leaving all tubular in place. 2. Close annulus and bullhead 50 sxs. of cement into the formation, WOC, observe wellhead pressure. 3. Remove wellhead and install "Dryhole" marker as per A.O.G.C.C. regulations. We expect to commence operations immediately on your approval, and your prompt consideration of this application would be appreciated. RECEIVED Erik A.

Chatterton Alaska Oil & Gas Conservation commission 3001 Porcupine Drive Anchorage, Alaska 99501 AprIl 11, 1988 REFERENCE: P & A Sundry Application for South Barrow Well 4{.18. Dear Mr. Chatterton: Enclosed is an application by 'Cne Nor"t:n s.lope Borough to plug and abandon well SB #18 in the South Barrow Gas Fields Pool Rules Area (Figure 1). This work continues, the North Slope Borough's effort to improve operational efficiency in the Barrow Gas Fields¡ and to eliminate conditions which could potentÌg.ll¥ pose safety or environmental problems. ,. ~l ",. \"':" 1 Historical Overview Well #18 was drilled by the Husky oil NPR Operations Inc. as prime contractor for the USGS f ONPF'cA, Ü. S. Department of the interior. The primary objective of this well was to delineate and develop gas reserves in the Barrow Sandstone along the northeastern flank of a small plugging' anticline which defines the East Barrow Gas Field. The well reached TD of 21251 on October 6, 1980. Two production tests were performed. The first. fIm/ad gas at the rate of 340 Mcf/day perforated between 2056 - 2074 in the Upper Barrow. The second test evaluated the Len..,,,'?:!::, Barrow bet.vIeen 2056.5 - 2076.5 which resulted in a calculated AOF of 1,650 Mct/day. The well was completed as illustrated in Figure 2, and eventually connected to the Barrow gas distribution system as a significant producer in the East Barrow Gas Field. with continued depletion of East Barrow reserves, production from this well has decrease, and changed character. XI:J.¿OX,.ELECOP I ER 295; AP¡:;O:- 1 1 -~::=: t-1ot·~ 4-11-88; 3:00 PM; ~ 9v(2?67542 ; # 3 1 .,.."'" .-" '-" . P.Ø3 A.O.G.C.C. P & A SB #18 Page 2 of 2 04/11/88 At present the well is producing approximately 20 Mef/day (approximately what is required to operate the associated surface facilities), along with 8 bblsjwater and 1 bbljday oil. The production of beth water and O~~ have established a increasing trend of over the past yea.r which is expected to accelerate with further aquifer encroachment. Current Barrow Gas Field facilities are not able to handle any significant amount of produced fluids. Oil is particu.larly difficult to handle with well designs which produce gas up the annulus, and blow rathole fluids to atmosphere through the production tubing as routine operating procedure. Give the above, we intend to plug and abandon SB #18 as specified in the following Operations Plan and attached Application for Sundry Approvals. General Operations Plan To accomplish the abandonment work, we W~ll employ the following plan for SB #18 which has now been successfully employed on three other south Barrow wells: 1. Circulate permafrost cement down 2-7/811 Tbg and up the 2-7/8" x 7" annulus to completely fill the entire hole volume with cÐment, leaving all tubular in place. 2. Close annulus and bullhead 50 sxs. of cement into the formation, HOC, observe wellhead pressure. 3. Remove wellhead and i:rtstall IiDryhole" marker as per A.O.G.C.C. regulations. We expect to commence operations immediately on your approval, and your prompt consideration of this application would be appreciated. '--'--"'---"...,.,,- Erik A.

GEOLOGIC SUMMARY INTRODUCTION South Barrow Well No. 18 was drilled on the nose of a small east plunging structure, approximately 10 miles southeast of Barrow, Alaska. Drilling below conductor casing (95') began on September 22, 1980. Lower Cretaceous and Jurassic rocks were penetrated. The well was terminated on October 5, 1980 in the basal portion of the Lower Barrow sandstones at total measured depth of 2,135 feet. The rig was released on October 14, 1980 after production tests were completed. Six conventional cores were cut and two production tests performed. In each of the South Barrow wells drilled after South Barrow No. 13, an inhibitive mud system, containing calcium-chloride, was used after 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. South Barrow Well No. 18 was completed as a producible gas well in the Lower Barrow sandstone from perforations at 2056.5-2076.5' in the 7" casIng. Calculated AOF was 1.65 MMCFGPD (see Appendix G). PRE-DRILLING PROGNOSIS The primary objective of the well was the Lower Barrow sandstone which was expected at a subsea depth of -2035'. A thickness of 20-25' of porous sandstone was anticipated. Secondary objectives were the Upper Barrow sandstone and possibly thin sandstones in the lower part of the "Pebble Shale" . POST-DRILLING SUMMARY I I I I I I The Lower Barrow sandstone, expected at a subsea depth òf -2035', was encountered at -2022'. Twenty feet of good porous sandstone with good hydrocarbon shows were present. Porosities varied from 20-29% with low water saturations of 20-33% (E-Iog). Two production tests were performed on this sandstone. The first, through perforations at 2056-2076', flowed gas at the rate of 340 MCFGPD. Test No.2, through perforations 2056.5-2076.5', flowed at a calculated AOF of 1.65 MMCFGPD (see Appendix G). . . Fair to good porosities (15-18%) were present in the sandstone, but water satu rations were fai rly high permeabilities generally low. Upper Barrow (59-86%) and I I I I I I I I I I I I I I I I I I I Hydrocarbon shows were present in the Torok and Kingak Formations and in the "Pebble Shale", but the sandstones were thin and not deemed worthy of testing. 2 ------------------- ~ I +. ~........'\ ."., H., , 8ARROW~n' Ie \0....11 , . -~A"'.020 wHo.

WELLSITE GEOLOGIST'S REPORT BY: R. G. BROCKWAY INTRODUCTION South Barrow Well No. 18, 660' FSL, and 1320' FWL, SW 1/4, protracted Section 24, T22N, R 1 7W, Umiat Meridian, d ri lied from under conductor casing September 22, 1980, and terminated on October 5, 1980, at a depth of 2, 135 feet. Sedimentary rocks of the Torok Formation Cretaceous age and the Kingak Formation, sandstones, of Jurassic age were penetrated. primarily the Upper and Lower Barrow sandstones in the" Pebble Shale" as secondary objectives. and "Pebble Shale" of including the Barrow Zones of interest were with possible sandstones Hydrocarbon shows were present in all formations, but only the Lower Barrow sandstone (2052-2072') was deemed worthy of testing. A production test was performed on the Lower Barrow sandstone and obtained a calculated AOF of 1.65 MMCFGPD. Well No. 18 extended the South Barrow Gas Field approximately one-half mile east and north of existing wells in the field. STRATIGRAPHY WIRELlNE TOPS Drilled Depth (BKB) Sub s ea Depth KB 30' CRETACEOUS Torok Formation "Pebble Shale" 95' Samples start 1373' -65' -1343 . JURASSIC Kingak Formation Upper Barrow sandstone Lower Barrow sandstone Total Depth 1758' 1976' 2052' 2135' - 1 728' - 1 946' -2022' - 2105' CRETACEOUS Torok Formation: 95-1373' The Torok Formation is composed of interbedded claystones and siltstones. The claystones are light gray to light brownish-gray, soft, silty, and slightly carbonaceous. The siltstones are light to medium gray and 6 . . I I I I I I I I I I I I I I I I I I I gray-brown, soft, and clayey, with ca rbonaceous fla kes, traces of pyrite and fossil fragments, and with rare silty limestone stringers. A few thin sandstone stringers are present above 1245', but increase in frequency below this depth. These sandstones, which do not exceed 5' in thickness, are light to medium gray, very fine grained, subangular, medium sorted, partly silty and clayey and slightly carbonaceous. Minor oil and gas shows were observed in the lower sandstones. A 60' core was scheduled at 1350' in an effort to core the contact between the Torok Formation and the "Pebble Shale". After cutting 21', the core barrel jammed and only 12' of gray-brown shale with 85° fractures and hydroca rbon stai ns was recovered. A second core was immrpdiately cut (1371-1400') which also jammed after 29'. Twenty-two and one-half feet of this core was recovered and consisted of dark brownish-gray fissile, flaky shale with fish fragments common, indicating that this core was from the "Pebble Shale". No evidence of the Torok-"Pebble Shale" contact was present in the second core, so it is assumed that Core No. 1 jammed at or near the contact, losing that portion of the core from the core barrel. Electric logs show the contact at 1373', but the difference in depth may have been an error in pipe tally. "Pebble Shale": 1373-1758' Lithology of the "Pebble Shale" is dark gray-brown and dark brownish-gray, fissile, slightly micaceous, carbonaceous shales with "floating" rounded, slightly frosted quartz grains and dark gray to black chert pebbles and granules and scattered pyrite inclusions. Fish fragments were noted in Core No.2. I nterbedded with these shales are light gray and gray-brown micaceous, carbonaceous siltstones. At 1560', a series of evenly spaced (20-30') thin bedded sandstones occur to a depth of 1680'. These sands are 3' to 5' in thickness, light gray to light gray-brown, very fine to fine grained, subangular to subrounded, silty and clayey, moderately friable, and carbonaceous with an estimated 7-15% porosity and hydrocarbon shows. Core No.3 (1703-1763') was cut in order to' obtain the Cretaceous-Jurassic contact. The contact was encountered at 1757.6' in the core. The upper 42' of Core No.3 was composed of interbedded siltstones, sandstones and shales. The siltstones are brownish-gray to dark gray-brown, sandy, and carbonaceous. The sandstones are very light brown to gray-brown, very fine to medium grained, subangular and contained hydrocarbon shows. The shales are dark brown, fissile, and carbonaceous with fish fragments. Some glauconite grains were present in the upper 4.5'. Scattered throughout the interval were black and dark gray chert grains and pebbles, rounded quartz grains, and pyritized plant or fossil remains. Large pyritized and carbonized wood fragments were also present. At 1745', a transitional zone begins. At this point, the shales become very dark gray-brown, moderately to very carbonaceous, and sandy with rounded quartz grains resembling those found "floating" in the shales of 7 I I I I I I I I I I I I I I I I I I I . . the upper part of the formation. Occasionally these sand grains occur in clusters forming sand inclusions in the shales. At 1752.5' to 1753.4', they become plentiful enough to form a shaly, medium to very coarse grained, rounded to subrounded sandstone, with black chert pebbles common. A slight hydrocarbon show was observed in this sand. Dark chert pebbles and granules are common to abundant throughout the transition zone with a general downward Increase In size, reaching measurements of two inches in diameter. I mmediately below the transition zone is a 0.6' conglomerate (1757-1757.6'). This conglomerate, which came from the core barrel as unconsolidated material, is composed primarily of light to dark gray and black chert pebbles up to two inches in diameter, with occasional light quartz granules and pebbles giving it a slightly "salt and pepper" appearance. A portion of the unconsolidated material was washed, and traces of dark gray shale, probably the cementing matrix of the conglomerate was detected. Some very light gray, very soft clayey siltstone and silty clay were also present. The siltstone and clay from the washed material could belong in the conglomerate, but probably belongs to the uppermost siltstone and shales immediately below the conglomerate. A similar conglomerate was also observed in South Barrow Well No. 15, Section 23, T22N, R 17W, Umiat Meridian at a depth of 1911'. Whether it is present in other nearby wells is not known at this time. JURASSIC Kingak Formation: 1758-2135' Interbedded shales and claystones, siltstones, and sandstones compr'ise the Kingak Formation with the sandstones most prominent below 1916'. The claystones and shales are light gray to light brownish-gray, soft, and silty, with scattered sand grains and streaks of gray-brown carbonaceous shale. The siltstones are light gray, light tannish-gray to tan, partly clayey, slightly micaceous, contain grains and pellets of glauconite and are rarely sideritic. Although the sandstones are most prominent in the lower portion of the formation, they do not exceed 4' in thickness and are generally very fine grained, light gray to white, subangular, friable, and slightly glauconitic with a clay matrix. Hydrocarbon shows were present in two beds at 1916-1920' and 1963-1967'. The latter bed is a fine grained, glauconitic sandstone with coal stringers or partings which appear to be a good marker bed in locating the Upper Ba rrow sandstone some 7' to 10' below, at least in this well and in South Barrow Well No. 15. Light gray-brown shales and siltstones separate this sandstone from the Upper Barrow sandstone. 8 · . 9 I I I I I I I I I I I I I I I I I I I Upper Barrow sandstone: 1976-2052' The Upper Barrow sandstone (1976-2052') IS light brown to gray-brown, fi ne g rai ned, subangu lar, medium sorted, and quartzose with scattered glauconite pellets and grains, carbonaceous grains, pyrite inclusions, and thin interbedded shales and siltstones varying in color from light gray-brown to dark gray-brown. Core No.4 was taken in the interval 1990-2020' and consisted of predominantly sandstone as described above with tight shaly zones. Porosity streaks up to 22% (Appendix E) were present with slight shows of hydrocarbons. Some fossil fragments and pyrite replaced plant remains were observed with one large fossil resembling an ammonite in the interval 2005-2006.5'. No tests were performed in the Upper Ba rrow. Separating the Upper Barrow sandstone from the Lower Barrow sandstone is a 2-3' gray-brown shale, which is hard to distinguish in the drill cuttings, but shows well on the drilling-time logs. Lower Barrow sandstone: 2052-2072' The Lower Barrow sandstone (2052-2072') has a good porous 20' of sandstone. Below the porous sandstone is a sandstone, siltstone and shale interval. The Lower Barrow sandstone is the main gas-producing reservoir of the East Barrow Gas Field. The sandstone is a fine to medium grained, very light to light brown, subangular to subrounded, medium to well sorted, and quartzose, with scattered glauconite grains, fossi I fragments and casts and la rge wood fragments. Core No. 5 (2051-2072') was taken in the Lower Barrow sandstone. (A slight discrepancy in depths is noted between the E-Iogs and core depth. E-Iogs indicate top of Lower Barrow at 2052', but Core No. 5 starts at 2051' in Lower Barrow. There may be an error in pipe measurement. Fifteen and one-half feet of core were recovered from Core No. 5 and were comprised of sandstones with an average porosity of 23% (Appendix E). It contained an even dull to faint light yellow hydrocarbon fluorescence and good instant cut in chloroethane. Electric-log computations show 20-29% porosity and 20-33% water saturation (Appendix C). A production test was performed th rough perforations at 2056.5-2076.5' with a calcu lated AOF of 1.65 MMCFGPD (Appendix G). The lower part of the Kingak Formation, which includes Core No.6, is composed of interbedded sandstones and siltstones. The sandstones are medium to light gray-brown, fine to very fine grained, subangular, shaly and silty with scattered glauconite and pyritized fossil fragments. The siltstones are gradational with the sandstones and are gray-brown to light gray, sandy and shaly. Below 2095', the section IS composed predominately of siltstone with gray-brown and light gray-brown interbedded shales. The well was terminated in this sequence. Hydrocarbon shows became very weak in Core No.6 and were very weak or absent below. I I I I I I I I I I I I I I I I I I I . . HYDROCARBON INDICATIONS By the use of a microscope, ultra-violet light, and chromatograph, several hydrocarbon shows were observed during the drilling of South Barrow No. 18. The first shows encountered were present in the lower Torok interval 1215-1373'. Here the thin sandstones had a dull yellow fluorescence under the ultra-violet light with a light yellow streaming cut in the upper 85'. Below 1300', the fluorescence becomes light medium yellow to bright yellow with instant light yellow to slow light yellow streaming cut. No visible staining was observed under the microscope except in the 12' of shale recovered from Core No.1. Here a wet, watery looking stain occurred on the bedding planes and was scattered along the 85° fractures which were present throughout the 12'. This staining had a light bluish-yellow fluorescence and instant light bluish-yellow cut and had a good gassy odor. Some minor gas shows were recorded by the chromatograph (maximum 480 units). Most of the thin sandstones In the "Pebble Shale" exhibit some hydrocarbon show including gas indications on the chromatograph. Although no visible staining was observed, nearly all of these sandstones showed a' dull yellow to gold fluorescence and instant light yellow streaming cut. Because these sandstones did not exceed 5' in thickness, it was deemed not worthy of testing, although one sandstone at 1452-1454' had 970 units of gas. Hydrocarbon shows were minimal through the upper part of the Kingak Formation with the exception of two sandstones at 1916-1920' and 1963-1967'. The upper sandstone had a good medium yellow fluorescence and light bluish-yellow streaming cut. The lower sandstone exhibited only a trace of fluorescence and cut, but at 1916', the background gas increased to a high of 280 units, indicating that the thin sandstones in the upper Ki nga k contai ned some gas. I n the Upper Ba rrow sandstone, the ch romatog raph readi ngs indicate only a general increase in total gas, reaching 300 units at 2003', but a definite increase in petroleum vapors from a high of 60 units in the Kingak to an average of 180 units in the Upper Barrow. Core No.4 (1990-2020') did not display any visible staining under the microscope, but under the ultra-violet light reflected a faint dull yellow to faint whitish-yellow fluorescence and a very slow to instant light yellow cut. Electric logs show that the best porosity zone in the Upper Barrow is from 1995-2022' with an average of 15-189ó. This is well supported by the core analysis on Core No. 4 (see Appendix E), although occasional thin zones reached porosities up to 229ó. Permeabi lity va ried greatly from 0.07 to 115 mill ida rcies with the better permeabi lity occu rri ng in very th i n zones. The density and porosity logs indicate some gas present, but calculated water saturations are high with intervals 1986-1994' having 86°ó, 2000-2010' having 62%, and 2010-2020' at 599ó, using a 0.25 water resistivity, which was obtained from a drill-stem test sample chamber from South Barrow No. 15 (Appendices C f,. E). 10 . . I I I I I I I I I I I I I I I I I I I No tests were performed on the Upper Barrow sandstone. The Lower Barrow sandstone (2052-2072') showed increased gas readings up to 420 units and exhibited a faint light yellow to dull yellow fluorescence and instant light yellow to light bluish-yellow cut through the interval 2056-2066'. A dull yellow fluorescence was noted above, and below this zone to a depth of 2079'. Electric logs show porosities of 20-29% through this sandstone (Appendix D). Core analysis of 15' of sandstone recovered in Core No. 5 (2051-2072') showed an average porosity of 20.3% with a maximum of 27%. Permeability varied from a low of 38 millidarcies to a very high 2,627 millidarcies. It is very probable that the extremely high readings of permeability (four in number), are not representative of the sandstone and possibly reflect small induced fractures or bed disturbance. The highest reading of 2,627 millidarcies at 2059' was from a sample appa rently ta ken from a section of core immediately above a pulverized and shattered zone from 2059-2060'. A vertical fracture was noted in a tight sandstone stringer from 2061 -2061.6'. Millidarcies in the 200-400 range appear to be more typical of this sandstone with thin less permeable and porous zones present (Appendix E). Gas is indicated in the Lower Barrow sandstone by a cross-over of the neutron and density porosity logs and a lowered density on the density log. A production test was performed through perforations from 2056.5-2076.5', with a calculated AOF of 1.65 MMCFGPD (see Production Test, Appendix G). A core analysis of Core No. 6 (2072-2087') shows an average porosity of 13.7% with a high of 17.9%. Although porosities are still fair in this core, the permeability drops drastically with only one sample at 2075' reaching as high as 40 mi II ida rcies, and generally is less than 2.0 mi II ida rcies. Electric logs through this zone indicate an average of 10-11% porosity on the density porosity log with a wide separation from the neutron curve indicating a shaly content to the rocks. Core descriptions also state that the core is becomi ng shaly and si Ity, and hyd roca rbon shows are nil below 2079' . A correlation of the coregraph and the FDC-CNL porosity log indicates that the original depths on Cores No. 5 and No. 6 should be lowered approximately fou r to five feet. PRODUCTION TESTS Two production tests were performed. The fi rst, th rough perforations at 2056-2076', only produced at a rate of 340 MCFPD after being "rocked" with gas from South Ba rrow No. 19. The well was then ki lied with CaC 1 2 water and reperforated at 2056.5-2076.5'. Production Test No.2 was opened through a 14/64" choke with FWHTP 420 psi and calculated at 1.05 MMCFG PO, with a FBH P of 592 psi. The choke was changed to 20/64" two hours before end of test with tubing pressure stabilizing at 390 psi. Final calculated rate was 1.37 MMCFGPD with FBHP 1 1 I I I I I I I I I I I I I I I I I I I . . at 437 pSI. The well was then shut in for four hours and established a final shut-in pressure of 950 psi. (History of Drilling Operations, South Barrow Well No. 18, Husky Oil NPR Operations, September 1982, page 3.) Calculated Absolute Open Flow was 1.65 MMCFGPD (Appendix G). STRUCTU RAL DATA South Barrow Well No. 18 was drilled on the nose of a small east-plunging structure located in Sections 19 and 30, T22N, R16W, and Sections 23, 24, 25 and 26, T22N, R 17W, Umiat Meridian, approximately 10 miles southeast of Ba rrow, Alas ka. Several small faults have been postulated by H. J. Gruy and Associates, Inc. (Figu re 3) on the east end of the mapped structu re (Figu re 3), but after correlating South Barrow Well No. 18 with surrounding wells (South Barrow Nos. 19, 14, and 17), it appears that the difference in structural relief can be explained by the dip rate. If faulting is actually present, the displacement would have to be very small. After correlation, it was found that the top of the Lower Barrow sandstone in Well No. 18 is 49' higher than South Barrow No. 17, 17' higher than South Barrow No". 14, and 27' lower than South Barrow No. 19. Correlation with South Barrow No. 15, which is 136' lower than South Barrow No. 18, is somewhat more complicated, and the difference in structural position may well be due to faulting, which is indicated by the dipmeter log from South Barrow No. 15. Faulting does not appear to be present in Well No. 18 except for possibly one zone at 790-950'. From an average of 10° in a northwest di rection, dips increase to 43-50° in this interval. Immediately below the 790-950' zone dips decrease to 25°, but there is no change in di rection of dip. If a fault is present, then it cuts the well bore at 950'. Correlation with other wells shows very little or no change in total interval from the point of the possible faulting to the top of the "Pebble Shale". 12 I I I I I I I I I I I I I I I I I I I . .

Hewitt: I Logg"-ng operations were begun by Schl~~berger on South Barrow No. 18 at about 1800 hours OC"Cober h, 1~80, and DLL. CNL/FDC, E.I1C and HRD were completed at 0500 hours October 5, 1980. Some problems were encountered with the DLL but were quickly overcome a:d resulti.l'lg log quality was good to excellent on all logs except the BEG which was badly affected by gas in the mud colur~ resulting in numerous spikes and skips .from the base of the Lower Barrow up to casing. I I Log tops were: Kingak at 1754, Upper Barrow at 1974 and Lower Barrow at 2052. Corre1a'tion -,;i th South Earrow :¡o. 15 -...as very good wi tb the corres~onding tops in No. 15 at 1898, 2107 and aS8 res- pectively which puts No. 18 about 135 feet bigher than No. 15. I Quantitative interpretation "Í.ndicates the upper Barrow to be tight and shaly and mostly water-cearing with Sw values ranging from 59% to 86% and porosities in the 15% to 18% range. The Lower Barrow appears to be a very good gas sand. with porosities from 20% to 29% aDd Sw values of 20% to 33%. CNL/FDC" crossovers" cert.;¡j"nJ.y confL."'m the presence of gas as does the constant "bubbling" during log~...ng.

Because of the rapid change in resistivity anà the porosity fluctuaticns it is difficult to geta precise average over the whole 20 foot interval but a reasonable average of 35 ohms for resistivity and 23% porosity was used resulting in Sw of 33% ·..hich should be in the ball park.

I . . I I MEMORANDUM October 24, 1980 I TO: R. J. Mead FROM: Dan Lowe I SUBJ: So. Barrow Well No. 18 Flow Test I Barrow Well No. 18 was flow tested from October 10 through 13, 1980. The zone tested was the Lower Barrow Sanda from 2056.5' to 2076.5'. This was a four point back pressut:e test through cased hole with four shots per foot perforating the 7" casing. I The pay zone had a thickness of 21 feet and an average porosity of 23.8%. The following are the results of this test, as determined from the Horner plots that were plotted by Gearhart-Dwen.

At the time the test was begun, there was only dry gas being produced; but it is most probable that the formation still does contain a few barrels of CaCI water. Because this water is in the formation, this well is expected to perform better than as tested. I Before Well No. 18 is connected to the PR Station, it will be necessary to let the well fully clean up for about a week. The very corrosive nature of the CaCl water would do much harm to the pipeline and metering facilities. I Although the information from the well test does not indicate any damage, a thorough clean up of the well befere production is highly recommended. I ,~ '::"2" rJ I c-..~ Dan Lowe Copy to: R.

SOUTH BARROW WELL NO. 18 INTRODUCT!ON The South Barrow Well No. 18 is located in the East Barrow Gas Field (Figure 1). The designation "East Barrow Gas Field" is now applied to those wells which were earlier identified as "South Barrow Gas Field, East Area". The South Barrow Gas Field and the East Barrow Gas Field are now recognized as two separate fields. The well is 660 feet from the south line and 1 ,320 feet from the west line of protracted Section 24, Township 22 North, Range 17 West, Umiat Meridian (Latitude: 71°14'22.98" North; Longitude: 156°18'41.00" West). The Alaska State Plane Coordinates are: Y = 6,306,022.15 and X = 698,905.52, Zone 6. The elevations are 3D' Kelly bushing, 12' pad, and 7' ground. Rig-up started on September 19, 1980, and the well was spudded September 22, 1980, at 11:30 p.m. The primary objective of the well was the Jurassic Lower Barrow sand. The well was drilled to a total depth of 2, 135 feet and left as a suspended gas well. The rig was released on October 14, 1980, and was stacked out on the pad. Husky Oil NPR Operations, Inc. supervised and directed the drilling and support operations as prime contractor to the Department of the Interior, U. S. Geological Su rvey, Office of the National Petroleum Reserve in Alaska. Brinkerhoff Signal, Inc. was the drilling contractpr; Brinkerhoff Rig 31, a National T -20, was used to drill the well. , SOUTH BARROW 'l....

I I I I I I I I I I I I I I I I I I I . . INTRODUCTION After the 1976 drilling season, casing requirements were reviewed and design of casing strings standardized. Every effort was made to minimize weight and grade 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 (PS I) (PSI) SIZE(1) WE I G HT MIN. MAX. COLLAPSE BURST CONNECTION 20" 133#/ft. 55,000 80,000 1 , 500 3,050 STC 13-3/8,,(2) 72#/ft. 95,000 1 1 0 , 000 3,450 5,350 BTC 9-5/8,,(3) 53. 5#/ft. 95,000 " 0, 000 8,850 7,900 BTC 9-3/4,,(3) 59.2#/ft. 95,000 1 10 , 000 9,750 8,540 BTC 7" 38#/ft. 95,000 "0,000 12,600 9,200 BTC (1) aD tolerance to be within API requirements unless adjustment absol utely necessary to meet ID requirements. (2) Special drift to 12.25". (3) Special drift to 8.50". The following are additional requirements primarily to assure that the steel exhibits the metallurgical properties for Arctic applications and resistance to hydrogen embrittlement. 1. All pipe that is 13-3/8" OD and smaller to be quenched and tempered. 2. Run Charpy "V" notch tests on two random samples per 50 tons per heat. Minimum acceptance of 15 ft.-lb.@-50oF. Furnish test reports with order. 3. Perform all testing normally required for API approved pipe. 4. Furnish test reports for ladle analysis, quantitative analysis, and all check tests as per AP I requi rements. 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. 25 . . 3. Inspect at mill using Tuboscope's Amalog IV or equivalent on 9-3/4" and smaller, and at least magnetic particle on 13-3/8" and 20". All pipe to have special and area inspection together with full length API drifting. (Note special drifting requirements.) 4. Apply Arctic grade grease on all connections before installing thread p rotecto rs . 5. I nstall closed-end type th read protectors. Plastic plugs can be used to secure wrench openings in protectors. 6. Buck up thread protectors with impact wrench. Both mill and third party inspection personnel should observe the installation of thread protectors. 7. Palletize or containerize the tubulars, if possible, prior to shipment from mill. Do not haul pipe like cordwood in gondola railroad cars. 8. All pipe to be Range 3. 9. No "V" notching or metal stenciling on pipe body or collars. Casing for South Barrow Well No. 18 was programmed as follows: 13-3/8" conductor at ±80; 9-5/8" casi ng at ±1500'; 7" casing at ±2100'; 2-7/8" production tubing to be run to the producing zone should the well be completed. Temperatures In the reservoirs in the East Barrow gas field range from the upper 40's to the low 50's, degrees F. Because of the low temperature, production completions have been modified to prevent downhole freeze-off of the wells due to hydrate formation. Husky's usual procedu re has been to suspend a 2-7/8" string of production tubing in the 7" casing to the base of the producing zone. In South Barrow No. 18, this procedure was followed, since the tubing was suspended at 2,076 feet (base of perforations are at 2,076.5 feet). The well is then produced through the annular space between the 7" casing and the 2-7/8" tubing. The lesser pressure drop in the larger annulus helps to prevent the formation of hydrates downhole. The 2-7/8" tubing is then used for periodic injection of alcohol in order to prevent freeze-up conditions from occu rrlng. Casing run in South Barrow No. 18 was 13-3/8" conductor at 95'; 9-5/8" casing at 1519'; and 7" casing at 2126'. Tubing (2-7/8") was run with a mule shoe at 2076' in the fi nal completion. 26 I I I I I I I I I I I I I I I I I I I I .

ARCTIC CASING PACK I n production wells, wells suspended th rough summer months, and wells completed for re-entry with temperature recording tools, Baroid Arctic Casing Pack was used between casing strings. It is a stable, highly viscous 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 barrels 5.0 barrels 60.0 ppb per barrel of water 12.5 ppb 50.0 ppb 103.0 ppb The 7" x 9-5/8" annulus was Arctic Packed through the FO at 1194' to the surface. This was to protect the 2-7/8" x 7" annulus from casing collapse while the well was being produced through it. 37 I I I I I I I I I I I I I I I I I I I . .

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 c~rtainly 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 miximwn 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 '31; 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 !!J-f i ; [[!f US KY] ISKY OIL NPR OPERATIONS, INC..

KANE Wellsite Geologist Log Analyst 12/77 RELIEF WELL PROGRAM HUSKY OIL NPR OPERATIONS, INC. SOUTH BARROW WELL NO. 18 EAST AREA DATE: September 5. 1980 PREPARED BY: Dan Lowe APPROVED BY: R. J. Mead . . RELIEF WELL PLAN ASSUMPTIONS: 1. South Barrow Well No. 18 will be drilled as a straight hole. 2. For the purpose of this Plan, the top of the Barrow Gas Sand estimated depth 1970' was selected as the blowout zone. 3. The relief well can be safely located as close as 500' from the blowout well, as long as it is at 90° to the prevailing wind direc- tion. T~is assumption is based on the shallow depth of the pro- ducing zone, anticipated volume produced by a blowout would be no more than 5 10 million cubic feet per day, and there is no H2S present in the potential blowout zones. LOCATION: 1. South Barrow Relief Well No. 18 is located 500' on a N18° W bear- ing from South Barrow Well No. 18. See attached Area Topo Map. f. Additional relief wells can be located NW of the well in order to take advantage of the prevailing wind direction and access to the ice airstrips. PAD MATERIAL: 1. Additional relief well drilling pads may be constructed from materials gathered from the same general area of the existing borrow sites. AVAILABLE DRILL RIGS: 1. Parco 95, Nabors 1, Nabors 17, and Nabors 25, all located on the National Petroleum Reserve in Alaska, would be available to drill relief wells. 2. Additional drill rigs may be available on an emergency basis else- where on the North Slope and would be obtained as the need dictated. DIRECTIONAL DRILLING PROGRAM: 1. Rig up drill over 13 3/8" conductor and cement conductor in place. 2. Drill 12 1/4" hole to ±500'. Run 9 5/8" casing and cement with permafrost cement. Nipple up BOP stack, choke manifold, and kill lines. Test BOP stack and casing. 3. Drill 8 1/2" hole to ±625'. Kick off well on a bearing of S18W at 3° increase in drift per 100' of hole drilled for ±1100' (1725i MD). Run directional surveys and electric logs as required. Continue drilling to 1918' MD. Install 7" rams in BOP. Run and cement 7" casing. Test casing and BOP. . . 4. DrillS 7/8" directional hole to ±2130'. Run directional surveys and electric logs. Run 5" flush joint liner to TO and cement. Perforate liner and initiate well kill procedures for containment of South Barrow Well No. 18 blowout. All well kill fluid will be pumped into the well through tubing ~nd à packer. 5. During the directional well drilling phase, surface facilities for water storage will be constructed for the well kill operation. High pressure well kill pumping equipment will be obtained from Halliburton and Dowell on the Reserve and from their Deadhorse facilities. 6. Current inventories of casing and drill mud on the Reserve are sufficient to handle relief well operations. . SOUTH BARROW GAS WELL NO.18 95/8" CASING ~ EST. TOP OF KINGAK FORMATION 1750' EST.
