I apologize for this office dropping the ball on these wells. Thank you for your patience in this matter, Ron Wilson WI Tech 659-5524 ------------------------------ We have recently completed a mid year review of MIT data from our inspection database to see how many injection wells may be in question regarding MIT timing. Results of our review relating to BP-operated fields are as follows: MITs are past due for the following wells (injecting as of 7/31/2006) 1) PBU 04-13; due 1/8/2006 2) PBU S-101; due 2/25/2006 3) PBU NK-13; due 5/4/2006 4) PBU X-36; due 5/20/2006 5) PBU R-25A; due 7/24/2006 The following shut in wells are past their due date for M1T 1) MPU H-06; due 2/28/2006 (S1 since 7/2002) 2) PBU WGI-Ol; due 4/22/2006 (SI since 12/12/2005) 3) MPU F-41; due 5/14/2006 (S1 since 5/2005) 4) PBU S-31A; due 6/1/2006 (S1 since 12/2004) 5) PBU P1-01; due 6/4/2006 (S1 since 6/2006 for workover) 6) PBU PI-25; due 7/2/2006 (SI since 6/2006) 7) PBU GC-02C; due 7/22/2006 (SI since 4/2006) A MIT for each well injecting on the list should be conducted as soon as practical; please notify the Commission for an opportunity to witness. Regarding SI injectors, the Commission suggests deferring testing (at least 20f4 9/25/2006 9: 15 AM ·v \^'~ "~~-'VJ' V' "V ,. ,~'" ,v~<.' ~-,a \' ,'-'" '/... . the Commission's witnessed test) until injection is recommenced and well conditions have stabilized. There's also two wells with MITs that have apparently been done (not witnessed) that we would like to have for our database: 1) PBU 03-10; M1T 9/30/2005 (CMIT IAxOA) 2) PBU 04-08; MITs (IA and OA) done per monthly injector rpt; date unknown As with all operating companies, the Commission is willing to work with you to take advantage of operating efficiencies in scheduling M1Ts (perform multiple MITs per pad; perform tests during the more temperate months; etc.). Feel free to call if you have any questions, and thank you in advance for your prompt attention to those MITs that are past due.

PT and Rig in hole w/checks & 3" Jetting nozzle. Sat down on asphaltines in tubing at 1286'. Jetted tubing to 1451' with heated water. Pulle out of hole for a better jetting nozzle. Rig in hole and finish cleaning tubing to a depth of 3200'. lAP came down from 2000 psig to 1580 psig after the GLM was jetted clean. Injectivity was about 1.5 bpm at 860 psig. Left well SI for stimulation in AM. Fluids Pumped BBLS. Description 58O 2% KCL 15 Diesel 35 Methanol 630 Total Pumped Stimulation Operation 03/11/98 A Acid Stimulation Treatment was performed using the following fluids: SUMMARY Rig in hole with 3.0" jet swirl nozzle pumping 2% KCL. Loaded well with 287 bbls of water while taking returns up backside. SD pump at 11,300' to dry tag fill. Liner was clean to 13,350'. Jetted liner with water to 11,970'. Switched to acid and had HB&R roll diesel into the IA at 0.5 bpm. Jetted acid across liner from 11970' to 13,310'. Injectivity improved from 2.2 bpm at 1150 psig to 2.5 bpm at 875 psig. Swivel started leaking 17 bbls into water displacement. It couldn't be fixed on location so we limped in methanol and had HB&R finish the over displacement by BH down tubing. Jetted the acid out of the sump while water was coming out of coil. The over displacement was being pumped away at 4 bpm and 1200 psig when the coil parted at surface. Check valves were holding but we elected to cut over displacement short and FP tubing with diesel. Cold roll spliced the coil and POOH. Left well SI with 0 WHP and a 50 bbl diesel cap. Blew down coil with N2. IA was FP with 75 bbls of diesel. FL was FP with methanol, N2 and diesel. Fluids Pumped BBLS.

The permit to drill does not exempt you from obta/ning additional permits required by law from other governmental agencies, and does not authorize conducting drilling operations until all other required permitting determinations are made. The blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25.035; and the mechanical integrity. (MI) of the injection wells must be demonstrated under 20 AAC 25.412 and 20 25.030(g)(3). Sufficient notice (approximately 24 hours) of the MI test before operation, and of the BOPE test performed before drilling below the surface casing shoe, must be given so that a representative of the Commission may witness the tests. Notice may be given by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607. David ~(.

Be prepared for losses near any faults and formation interfaces between the Kingak, Sag River/Shublik and Sadlerochit. A minimum of 9.6 ppg mud weight will be used to drill the Cretaceous injection interval. This will allow a 100 psi L trip margin over the expected 9.5 ppg EMW @ 5000' TVDss. Disposal Cuttings Handling: Fluid Handling: Cuttings should be hauled to the ball mill at CC-2A. Haul all drilling and completion fluids and other Class II wastes to CC-2A for injection.
