FIG) Hi Jim, Here are updates to three of the wells requested. I am still looking into P2-34 but wanted to respond with the information I have at this time so thàt these reviews can be closed out. 13-22 failed an MITIA on 7/21/04 while the well was shut-in and on a vacuum. The plan has been to repair a gate valve, put the well on injection, and repeat the MITIA with the well on injection. The repair work has been completed and this well is on the schedule for an MITIA this week. The AOGCC inspector will be contacted to witness the test if possible. 03-36 failed an MITIA and passed a MIT-T on 8/2/04. An leak detection log confirmed a production casing leak at 8230' md on 8/11/04. Plans are to submit a request for Administrative Approval once M-38 AA has been approved to include any additional information required for the AA. NK-38 was not added to the monthly injection report given the plan is to workover the well instead of apply for Administrative Approval. The injection valve was opened on 9/19/04 to freeze protect the tubing and flowline for the winter. Please let me know if you have any additional questions. I will follow-up with P2-34 within the next few days. Thank you, Anna Dube -----Original Message----- From: James Regg [mailto:jim regg@admin.state.ak.us] Sent: Tuesday, October 26, 2004 4:57 PM To: NSU, ADW Well Integrity Engineer Cc: Winton GAubert Subject: Review of Wells w/Failed MITs We just completed a quarterly review of wells with MITs that failed and have identified 4 that need some clarification regarding status: 1) *PBU 13-22*; failed MIT 7/21/04; SI after MIT and well was added to monthly injector report; our database shows 3 days injection in September (26,996 bbls water); what is the status of request for administrative approval? [According to September Monthly Injector Report, tbg integrity was to be restored prior to placing on injection, and MIT was planned for 9/23/04; nor record of either] 2) *PBU 03-36*; failed MIT 8/2/04; well was added to monthly injector report; our database shows injection in August (9 days; 2,080 bbl water) and September (5,379 bbl water); what is the status of request for administrative approval? 3) *PBU NK-38*; failed MIT 7/12/04; well has not been added to monthly injector report; data provided to Commission indicates 32 bbls water injected (1 day) during September; what is status of this well and follow-up to failed MIT? 4) *PBU P2-34*; MIT 7/13/04; the Commmission carries this as an incomplete MIT (thus, requirements of 2 year testing for monobore injectors per AOGCC policy have not been satified); MIT is incomplete because only the upper 6,400 ft of the well (perfs at 13,000 ft) has been evaluated for mechanical integrity; it is also unclear if the well carries a waiver from 20 AAC 25.412 (packer within 200 ft of perfs) ; this well should be added to the monthly injector list. ~-' lof2 10/28/2004 8:00 AM RE: Review of Wells wIFailed MITs - 13-22,03-36, NK-38, P2-34 I'd appreciate an update ~1 the 4 wells so we can close ou~)our review. 2of2 Jim Regg AOGCC 10/28/20048:00 AM STATE OF ALASKA ALASKA OIL AND GAS CONSERVATION COMMISSION Mechanical Integrity Test ~. .' -J 'it..' \CA ~l' Yi ~ Emall to.Wlnton_Aubert@admin.stateakus:Bob_Fleckenstern@admin.state.ak.us:Jlm_Regg@adminstate.ak.us OPERATOR: FIELD I UNIT I PAD: DATE: OPERATOR REP: AOGCC REP: BP Exploration (Alaska) Inc.

The testing went well with all wells exhibiting competent tubing and casing. Wells # 10, 16 and 38 tubing injection pressures were high enough to exhibit the required minimum of 500 psi differential between tubing and casing. These wells were held and observed at their pretest comnditions for thirty minutes with no change in annulus pressures observed. The wellhouses and pad were in good condition; SubSidenCe does not seem to be a issue on this pad. M.I.T.

The rig was waiting on orders when I arrived· I found all BOPE equipment to be in place and in apparent good condition. This will be the last well on this pad for awhile due to modules that are to be installed as soon as the rig is done with this hole Access to the rig is getting quite cramped although still adequate.

The permit to drill does not exempt you from obtaining additional permits required by law from other governmental agencies, and does not authorize conducting drilling operations until all other required permitting determinations are made. Blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25.035. Sufficient notice (approximately 24 hours) 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 test.

The well design The West Sak sands may have minor oil shows but mud weight will exceed the 'formation pressure. The TK-3 sands from 6450' to 7250' TVDss may be overpressured by as much as 213 psi from DS 4 injection. Planned mud weight will also hold back this potential pressure. Due to the length (and corresponding friction) of 12-1/4" hole section, the 9-5/8" casing may not run to bottom.
