P.O. Box 100360 Anchorage, AK 99510-0360 Reference: Issuance of Permanent Closure Approval for Inactive Reserve Pits located at nine exploration sites located on the North Slope, Southcentral, and Interior Alaska Dear Ms. Pekich: The Alaska Department of Environmental Conservation (ADEC) has completed review and public notice for nine inactive reserve pit closure applications and requests for permanent closure approval. The closure applications provided the required information describing the history of the reserve pit(s), the present condition of the reserve pits(s), results of any required water sampling and an assessment of the potential risks posed by the drilling waste to human health and the environment. At these locations, the reserve pits have been backfilled and there is no exposed drilling waste. ADEC coordinated review of the closure requests with the appropriate land manager(s). Public notice requesting comments on the closure requests was published August 3 and 4, 2001 in the Anchorage Daily News and posted on the State Web Site August 2, 2001.. No public comments were received in response to this public notice. ADEC has determined that the reserve pits at these sites meet the closure re. quirements of 18 AAC 60.440. Closure Approval Under authority of 18 AAC 60.440 (j), ADEC grants permanent closure approval to Phillips Alaska 'Inc. for the inactive reserve pits at the following nine exploration sites: Well Name API Number ' Beluga River Unit 212-25 I C.~ 50-283-10025-00 Birch Hill Unit 22-25 %,-~%~ 50-133-10029-00 Swan.Lake Unit# 2 ~>~ ~X 50-133-10021-00 o%t4.~Falls Creek Unit # 1 (13-06) ~,~,~50-133-10005-00 Rainbow Federal # I P:~ ~ 50-099-10004-00 Rainbow Federal # 2 ~>~ ~X, 50-099-I0005-00 ~-~r3Kaliakh #2/2 RD D~' I:K 50-033-I0002-00/01 KRU West Sak SWPT #1~,os~ 50-029-20915-00 West Sak River State # 2 ~-~,b50-029-20134-00 MTRS Sec. 25 13N, 10W,SM Sec. 25 09N, 09W,SM Sec. 3 07N, 006W,SM Sec. 6 01N, 12W,SM Sec. 31 08N, 05W,CR Sec.

Ms. Lisa L. Pekich September 14, 2001 Page 2 Terms and Conditions This final closure approval is subject to the following terms and conditions: 1) In accordance with 18 AAC 60.440(1), the Department will require additional investigation, assessment, monitoring or remediation if new information regarding conditions at the reserve pit facilities indicates that further actions are necessary to protect human health or the environment. 2) The approval granted by this letter is for the inactive drilling waste reserve pit(s) only. Closure for the pad as a whole (if required) must be coordinated between the owner/operator and the appropriate land owner/manager. Any person who disagrees with any portion of this decision may request an adjudicatory hearing in accordance with 18 AAC 15.200-310. The request should be mailed to the Commissioner of the Department of Environmental Conservation, 555 Cordova Ave. Anchorage, AK 99501. If a hearing is not requested within thirty (30) days of the date of this letter, the right of appeal is waived. If an adjudicatory hearing is requested and granted, this decision remains in full effect during the adjudicatory process. Sincerely, Heather T.

DOC TELEPHONE NO: SUBJECT: Louis R Grimaldi~/~ Petr Inspector Location Clearance ARCO West Sak SWPT #1 Permit 83-28 Kuparuk River Unit Seotember..23,. !991 I made a visual inspection of the surrounding location of ARCO's West Sak SWPT #1 in the Kuparuk River Unit. This well was plugged and abandoned. I found all information on the marker to be correct. There is a pit existing on the pad. Upon visual inspection, I found no evidence of contamination by either drilling fluids or oil. It should be noted that it was a windy day. Due to surface disturbance, a sheen on the water might be difficult to see. There are a few wrecked vehicles and ATCO buildings on location that are used for fire training by ARCO's Fire Department. This equipment is kept neat and orderly. ARCO wishes to continue to use this pad for fire training and keep the pit for a water supply. If the Commission finds this acceptable, I feel that ARCO has satisfied the requirements of abandonment.

Box 100360 Anchorage, .Alaska 99510 Dear Mr. Knepler: 2~ae Alask~ Oil and Cas Conservation Commission has received your request, dated May 20, 1983, to flare hydrocarbon gas during% an extended production test of the ~est Sa~ Reservoir. The :West Sak SW~ Ne.~ I well is to be tested for a period of four to six ~nths beginning about June 1, 1983. %~..e test will provide data needed to evaluate the development potential of, the reservoir. It is ~" ~ ~;~up_~ru,~ River unuerstood that the well ~rill utilize the '~ . ~- Unit gas-lift system to gas-lift the well and routine flarin~l %zill not be required since the production ~..rl. ll be ~-....easured, recomozne and commingled w~_th Kuparuk River Unit production for processing. It is further understood that flarin~ ?~1! take place only when the well is produced under natura% flow conditions or into a production system operating at a lower pressure than t,_[~ Kuparuk River Unit facilities and the flaring may be necessary durin~ start-up'and GOR testing ~ is also understood t]~at al~ volumes of produced oil and gas and the gas-lift gas will be measured adequately to provide ~aningful data fro~ the test. From your application, it is estimated that flaring will take place about 20 percent of the ti~e and the volume of gas to be flared will be less than 15,000 ?~SCF during the life of the test. By this letter the Alaska Oil and G~s Conservation. Core, mission ' 000 mereby permits ARCO Alaska, Inc. to flare a maxim~s~ of 15,. ~ of ~ · ~o.~,~ gas der-'~,-~ the .~ix month test c'~ the l,~est ~,~a~q' SWPT Us well. %he testing will be done in a manner to keep the flared vo!m~es of ~= to a minim~ and the Commissar.r,. aavzse~ on the progress oy adequate monthly reports. Mr. John ~K~epler Page 2 May 23, 1983 This letter will further advise you that the requested confiden- tiality of the t~st will be honored except that, by statute, the produced volum~s of oil, gas and water must be made available to the public each month.

ARCO Alaska, Inc., proposes to alter the 13-3/8" casing program previously submitted and approved for West Sak SWPT #1. In the future, we plan to complete the subject well for steam__stimulation of the West Sak Zone. It is will average~212°FX~rom TD to surface. There is a anticipated that production casing temperatures possibility that free water could be left within the ±200' plug o~5/8" x 13-3/8" shoe cement. If this water is unable to escape through the cement when heated, it will generate collapse forces on the 9-5/8" and burst forces on the 13-3/8". We wish to design the casing program to increase the chances of 13-3/8" burst. 13-3/8", 54.5#/ft, K-55, 8rd STC casing would be ran from 1831' TVD to 2271' TVD. The rest of the casing program remains unchanged. Permafrost depth is estimated at 1771' TVD. Therefore, no "unapproved" casing will be ran through the permafrost. If the permafrost base comes in deeper than predicted, the 54.5#/ft K-55 will'be ran on the bottom 440' of the surface casing string. In no instance will the 54.5#/ft, K-55 be ran deeper than 2600' TVD. Estimated Spud: April 1, 1983 14. I hereby certify_that the foregoing is true and correct to the best of my knowledge.
