Attn: Well Integrity Coordinator, PRB-20 Post Office Box 196612 Anchorage, Alaska 99519-6612 January 1, 2010 ~»~'~~~~ J~i~~ ~ ~~~ 20 6C Mr. Tom Maunder Alaska Oil and Gas Conservation Commission / ~3 333 West 7t" Avenue Anchorage, Alaska 99501 ` S' ,~ (~ ~p Subject: Corrosion Inhibitor Treatments of GPB DS 15 Dear Mr. Maunder, Enclosed please find multiple copies of a spreadsheet with a list of wells from GPB DS 15 that were treated with corrosion inhibitor in the surface casing by conductor annulus. 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, Anna Dube. Sincerely, Torin Roschinger BPXA, Well Integrity Coordinator • • BP Exploration (Alaska) Inc.

ITEM 1a: Classification of Service Wells: Gas Injection, Water Injection, Water-Alternating-Gas Injection, Salt Water Disposal, Water Supply for Injection, Observation, or Other. Multiple completion is defined as a well producing from more than one pool with production from each pool completely segregated. Each segregated pool is a completion. ITEM 4b: TPI (Top of Producing Interval). ITEM 8: The Kelly Bushing elevation in feet above mean low low water. Use same as reference for depth measurements given in other spaces on this form and in any attachments. ITEM 13: The API number reported to AOGCC must be 14 digits (ex: 50-029-20123-00-00). ITEM 20: True vertical thickness. ITEM 22: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool. ITEM 23: If this well is completed for separate production from more than one interval (multiple completion), so state in item 1, and in item 23 show the producing intervals for only the interval reported in item 26. (Submit a separate form for each additional interval to be separately produced, showing the data pertinent to such interval). ITEM 26: Method of Operation: Flowing, Gas Lift, Rod Pump, Hydraulic Pump, Submersible, Water Injection, Gas Injection, Shut-In, or Other (explain). ITEM 27: If no cores taken, indicate "None". ITEM 29: List all test information. If none, state "None".

BP 15-46L1 Sidetrack Summary of Operatious: Well 15-46 is scheduled for a through tubing sidetrack with SLBlNordic 1 in Late June. Production from the existing ,,/ well will be retained with a flow thru whipstock set at approx 11,815' in the 4-1/2" liner. The well targets Zone 1 reserves. The sidetrack will be completed with a slotted/solid un-cemented liner. A schematic diagram of the proposed sidetrack is attached for reference. Contingency will be to run solid cemented and perforated liner if high loss circulation / is encountered, a sundry will be submitted at that time if needed. Pre CTD Summary / 1) Slick-line - Drift tubing and liner. Dummy gas lift valves. Pressure test IA to 2500 psi. 2) Service CTU - Drift liner, set flow thru whipstock anchor with check valve. Run whipstock tray, latch into anchor to space out top of whipstock at approx. 11815' md. CTD Sidetrack Summary 1) MIRU CTD rig. c 2) Mill 3.8" window off of whipstock. / 3) Drill 4-1/4" x 3.75" open hole sidetrack to 13815' planned TD with MWD/gamma ray. 4) Run 3-3/16" x 2-7/8" slottedlsolid un-cemented liner completion. Top of liner will be left at 11750' md in 4 Y2~ liner. 5) Run MCNL. 6) RDMO. Mud Program: · Phase 1: ~'~g seawater · Phase 2~pg used Flo Pro or biozan for milling, new Flo Pro for drilling. Disposal: · All drilling and completion fluids and all other Class II wastes will go to Grind & Inject. · All Class I wastes will go to Pad 3 for disposal. Casing Program: · A 3-3/16" x 2-7/8" solidlslotted un-cemented liner completion from 11750' (8760'tvdss, 90deg inc.) to TD at / 13815' (8720'tvdss).
