Due to the GC2 TAR the wells have been shut in and were not tested before the end of the month. GC2 is expected to be back up to full rate by the end of next week so BP is requesting to leave the above mentioned wells in Operable status and track them on the monthly compliance report until they are brought back online and pressure tested.

(BPXA) requested approval to allow enriched hydrocarbon gas injection in Well PBU Polaris W-219 (PTD 2101050)). The Alaska Oil and Gas Conservation Commission GRANTS BPXA's request in accordance with Rules 2 and 13 of AIO 25A.000. An Application for Sundry Approval (Form 10-403) is not required; however a Report of Sundry Well Operations (Form 10-404) must be submitted documenting the commencement of enriched gas injection. 5141 DONE at Anchorage, Alaska and dated March 9, 2011. t• " ` L Itfa ,44 Av Daniel T. .eamount, Jr. Cathy ..

Dave, Your cementing plan meets regulatory requirements. Go ahead with your plan as written. Also, as you are moving the BHL less than 500 ft a PTD revision will not be needed. The Open hole PB data and operations should be included in the final 407 report. Guy Sent from my iPhone On Nov 13, 2010, at 9:20 PM, "Johnson, David A (Swift)" <David.A.Johnson @bp.com>wrote: Guy, Attached is the revised plugging and sidetracking procedure for W-219. We plan on setting three cement plugs from 6960' MD to 5100' MD. The plugs will bee 600', 600', and 660' in length. All permeable zones will be covered. The top of the Ugnu Ma is at 6030' MD. The kickoff point will be at 5220' MD. The directional plan is attached. The bottom hole location will move —203'.

The 8-3/4" hole was drilled to 6940' MD. A fault was crossed at - 6599' MD in the Schrader sands. It is necessary to plug the well back and sidetrack to cross to the other side of the fault. It is planned to spot cement across the Schrader and Ugnu sands as necessary for sidetracking. The KOP is at 5220' and cement will be brought to 5100' MD with three plugs. The top of the Ugnu Ma is at 6030' MD. All permeable zones will be covered HSE: PJSM's are required before every task. Please assess hazards and mitigate the risks before starting a job; even if the task seems to be a menial task to you.

(BPXA),requests administrative approval under Area Injection Order No. 25A(AIO 25A)to allow for the injection of enriched hydrocarbon gas into injection well W- 219. The rule provides that upon "proper application"additional water injecting wells can be reclassified as WAG injectors. BPXA requests that this AA be approved as part of the Permit to Drill. a- -/-h s Not y The area of review for this planned injector shows that there are no offset injectors present within a one- _m_ia quarter mile radius of W-219 as depicted by Figure 1.The only other wellbores present within a'A mile of W-219 planned well path are W-17,W-17A, and W-212i.

Free gas and/or gas hydrates may likely be present in the SV5 through the SV1 surface hole below the Permafrost base. Use standard operating procedures for hydrates, if encountered. Set surface casing below deepest SV1 sand hydrate zone to isolate gas bearing intervals behind cemented pipe in surface hole from intermediate hole section. III. Running Gravels: A. Unconsolidated sand, gravel, &cobbles and thawing permafrost could impede well angle build and casing running through permafrost. Keep moderate to low build angles until out of permafrost section. Keep flow rates low. Hazards include wood and cobbles, running gravels, lost circulation, and tight hole problems while drilling and running casing. See W Pad Data Sheet for details. B. Recent W Pad wells have experienced tight hole, running gravels, and lost circulation with drilling and running casing in Permafrost interval. Use best practices for drilling and lining surface hole interval. Base plan is to use the Tesco CDS casing running tool to address this problem for 9- 5/8"casing. IV. Faults Formation Where MD Est.
