The corrosion inhibitor is engineered to prevent water from entering the annular space and causing external corrosion that could result in a surface casing leak to atmosphere. The attached spreadsheet represents the well name, API and PTD numbers, top of cement depth prior to filling and volumes of corrosion inhibitor used in each conductor. As per previous agreement with the AOGCC, this letter and spreadsheet serve as notification that the treatments took place and meet the requirements of form 10 -404, Report of Sundry Operations. If you require any additional information, please contact me or my alternate, Gerald Murphy, at 659 -5102.

The wellhead pressures were tubing/IA/OA equal to SSV/2100/100 psi on 07/06/08. Due to the constraint of not being able to bleed pressure down to the production system due to the shut-down, the diagnostic work took longer to complete. On 07/10/08, a TIFL was conducted and failed due to build up of pressure overnight confirming TxIA communication. The well has been reclassified as Under Evaluation and placed on a 28-day clock.

Supervisor R~: Water & Gas to Su~ace ~ BPX PBU A-Pad -- . · We got the gas sample analogous back from the lab and it ~s confirmed - that the sample ~s Li~ Gas and not MI. .___ Lift gas was shut off in the five wells one at a time, when the LG in well A- 7 was shut-in and the IA bled off, the gas bubbling and water in all cellars subsided. It took about 3 hours for the water to evacuate the cellar in A-5. ! wen~ back to the Pad at about 6:00 PM, there was no water in any of the-"'~ellars however there was gas still bubbling up in A-5 & 40 cellars. The injection rate on well A-Si had been brought back up to 3350 psi, and all annuli were bled to 100 +/- psi. The gravel inside and outside of the cellars of A-___5~4_.0 & 4_3 had subsided about 24" this subsidence extended about two foot around the outside of the weilhouses. Tomorrow 12/13/96 we will simulate the same condJtions that existed w~en the flow to surface commenced, if A-7 will continue to flow ali night without LG. This should confirm or deny that A-~ the fault of this flow. I will write a real report to you and David after we have the final results of tomorrow's simulation. This is just a FYI to keep you up to speed on the issue. If you have any other questions you need answered please call me at 448-1227 or page me and I will do my best to answer them for you.

Date: Daily events 1¢6-96 1¢:8-96 1~-9-96 GC-3 produced water system was shut down for 18 hours for repairs in skid 301. Subsidence was reported in well house of Well A-43. Well A-08i was converted from produced water(PW) to :" .'. miscible injection (MI). This is the first time A-08i has been · on miscible injection. The following readings were on produced water. FWHP:1050psig, FWRT: 140deg F, IA: 100psig, CA: 560psig 1¢,.10-96 A-pad & X-pad went down due to logic problems, ali wells were down for 5 hours. A-08i well readings on MI; WHP:3350 psig, WHT: 130 deg F, IA: zero, CA: zero The night Pad Operator found standing water in the cellar in well A-7. The day Pad Operater found flooding with gas bubbling in well houses A-43, A-40, and A-5 cellars. LEL readings are found to be as high as 30% in cellar but only a traCe inches above cellar. Twenty four hour man watch initiated by Production Engineers. Samples of w~ter taken by BPX lab and found to be fresh at 1000 ppm chlorides. Area has been roped off and access restricted. Peak vac truck brought on location and sucking down cellars as needed. Alaska 0il & C:~s Cons. knchcr~.g0 Miscible Injection was shut in on well A-Si. No effect was found on offset wells. Well was brought back on at half rate to monitor watt integrity. A-Si casing pressures remain at zero. 10-11-96 Night pad operator reported major subsidence plus water/gas in Well A-43 well house. Well A-5 has major gas/water production. Gas samples taken from Well A-5 cellar by BPX lab. Vac Truck recovered 1000 bbls of water from cellars. Watedgas production has ceased in Well A-7. Wells A-43 and A-40 have subsided by 30%. Well A-5 watedgas production continues unchanged. Waiting on gas analysis. Vac truck ceases liquid recovery but remains on location with man watch. Subsidence of wails in question since September 1996: A-07: None A-05: 4 yards of gravel A-40: 10 yards of gravel A-43: 62 yards of gravel Note: Previous records could not be found by subsidence crew. Night Pad Operator reports conditions are improving. Area remains restricted and man watch continues. Please find attached the pad map, Pad Operator's daily readings and comments. Course of action and Interpretation. Continue to monitor wells and sample liquid and gas production for possible well integrity failure, At this time a suspected failure of well Integrity is not warranted. The source of the fresh water is assumed to be from known underground streams which were documented prior to pad construction in the early 1970's. The suspected cause of the problem is continued melting of the permafrost by each wells proximity and the migration of gases known to exist in and under the permafrost. · Alask.3. 0it & ¢ ~mS Cons.

JAY S. HAMMOND, July 20, 1976 G. D. Taylor Manager Operations BP Alaska, Inc. P. O. Box 4-1379 Anchorage, Alaska 99509 Re' Casing Design in the Permafrost Interval Dear Mr. Taylor' Your letter of June 28, 1976, stated that five of your Prudhoe Bay wells had 13 3/8" surface casing strings through the p~rost which included 68 lb/ft,N-80 buttress casing. These wells ar A~_~C~ C-5, C-6' C-7 and C-8. Based on your studies you submit that 13 3-/~T", 68 lb/ft, N- 8O buttress casing satisfies Rule 3(c) of Conservation Orders No. 98A, No. 98B, and No. 83C. The above Rule 3(c) states that surface casing through the permafrost shall have minimum post-yield strain properties of 0.9% in ten'sion and 1.26% in compression. Arco's May 1975 report, "Prudhoe Bay Field Permafrost Casing· and Well Design for Thaw Subsidence Protection", describes results of full.. scale strain limit tests on 13 3/8", 72 lb/ft, modified N-80 (~.lN-80) buttress casing and' of a finite element model calibrated from the tests. Results of Arco's tests and studies indicated 13 3/8", 72 lb/ft, MN-80 buttress casing exceeded requirements of Rule 3(c).~ · One of the prime reasons that controlled yield or modified MN-80 casing was specified in the Arco tests, was to preclude the practice of manufac- turer's substitution For N-80, with higher steel grades which, due to I~tlysical p'rol)er~ies, ·Fail in Arctic ai~plications. ThereFore, apl~roval oF N-~O grade casing 'For sur[ace casiI~g Lhrougt~ the perlna[ros~ requires assurance that other grades 'have not been substituted for N-80. "1776-A llilltUll:.

Hamilton -?- -~'~ July 20, 1076 Your studies LISin.(} Arco's finite element mocl61 denlonstrated that failure strain in compression for 13 3/8" 68 lb/ft, MN-~O buttress casing was 4.2%. Results of finite model calculations shown in Table III-1 of the above mentioned Arco report alludes that failure strain in tension for the same casin~] exceeds that of 13 3/F~', 72 lb/ft, ~qH-~O buttress casing. O~r analysis supports this point. Based on these studies, 13 3/8", 68 lb/ft, ~lN-80 buttress casing adequately meets the requirements of P, ule 3(c) of Conservation Orders No. 98A, No. 98B, and Ho. 83C. Sincerely, Hoyle H.
