Attn: Well Integrity Coordinator, PRB-20 Post Office Box 196612 Anchorage, Alaska 99519-6612 January 1, 2010 Mr. Tom Maunder ~~~G~~ J~J~ 2010 Alaska Oil and Gas Conservation Commission 333 West 7th Avenue n ~~~ Anchorage, Alaska 99501 4t,, Subject: Corrosion Inhibitor Treatments of GPB DS 06 ~ ~J ''` d Dear Mr. Maunder, Enclosed please find multiple copies of a spreadsheet with a list of wells from GPB DS 06 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, at 659-5102. Sincerely, Torin Roschinger BPXA, Well Integrity Coordinator • BP Exploration (Alaska) Inc.

This permit to redrill does not exempt you from obtaining additional permits or approvals required by law from other governmental agencies, and does not authorize conducting drilling operations until all other required permits and approvals have been issued. In addition, the Commission reserves the right to withdraw the permit in the event it was erroneously issued. Operations must be conducted in accordance with AS 31.05 and Title 20, Chapter 25 of the Alaska Administrative Code unless the Commission specifically authorizes a variance. Failure to comply with an applicable provision of AS 31.05, Title 20, Chapter 25 of the Alaska Administrative Code, or a Commission order, or the terms and conditions of this permit may result in the revocation or suspension of the permit. Please provide at least twenty- four (24) hours notice for a representative of the Commission to witness any required test.

It has 9-5/8" intermediate casing set on a mandrel hanger and packoff. The current completion is a 5-1/2" crossed over to 4- 1/2" just below the well head. Top threads of the hanger are listed as 5-3/4" RH ACME running threads. The bottom threads should be LTC-M. Have a spear on location as a contingency to pull the Hanger to the floor. - There is a 4-1/2" Otis HRQ SSSV Landing Nipple at 2203' with 2, ~/a" encapsulated control lines run to surface. The current tubing tally states there are 33 steel bands securing these control lines. - A 7" tie-back will be stung into the current 7" liner and brought back to surface.

Once the window is milled the 14 day test cycle starts and continues until the rig moves off the well. - A 9-5/8" whip stock will be run and set in the existing 9-5/8" 47# liner. A 8-1/2" window will then be milled in the 9-5/8" 47# liner. - According to the volumes pumped, it is questionable whether we will have cement behind the 9- 5/8" casing at the sidetrack point. - The window will be cut in the existing 9-5/8" casing into the Ugnu formation. Ensure entire wellbore has been circulated to 9.0 ppg mud before milling commences. - Once milling is complete, circulate a minimum of 1-1/2 bottoms up and pump a "Super Sweep" pill to remove metal debris created from the milling process. Ditch magnets should be used throughout job. - Once the milling BHA is out of the hole the entire stack and flow lines should be flushed to remove metal debris that may have settled out in these areas. Ensure BOP equipment is operable. Job 4: Drill Intermediate Hole Reference RP • Standard Operating Procedure for Leak-off and Formation Integrity Tests • Prudhoe Bay Directional Guidelines • Lubricants for Torque and Drag Management. • "Shale Drilling- Kingak & HRZ" Issues and Potential Hazards - 06-066 is expected to cross one fault in the intermediate hole section. The approximate location of the fault is 10,200' and (+/- 100' laterally uncertainty) and has a very small estimated throw at the planned crossing depth. The throw of the fault grows to 100' at the TMLV. Lost circulation is considered a minimum risk. If losses/breathing is encountered, consult the Lost Circulation Decision Tree regarding LCM treatments and procedures and adjust drilling practices to reduce breathing phenomena. - A 7" tie-back will be stung into the new 7" liner and brought back to surface. Cement will be brought up to 2,500'. The top 3,000' of 7" will be premium threads. The rest of the 7" tie-back will be the BTC-M connection. - Differential sticking of drillpipe and casing could be a concern in the West Sak and Ugnu formations. To combat this, Mix II and/or G-Seal will be strung in the mud as these intervals are drilled to "block" the intervals as they are penetrated. This will prevent differential sticking, mud loss, and thick wall cake. 06-06B Permit to Drill -Version 1.0 Page 9 • • - KICK TOLERANCE: In the st case scenario of 8.0 ppg pore pressure at the top Sag River depth, gauge hole, a frac re gradient of 12.5 ppg at the surface casing shoe, 11.3 ppg mud in the hole, the kick tolerance i 26 bbls. - There are 3 wells that fail the "major risk close approach" scan in the intermediate hole interval. Details are in the attached Anti-Collision report. Phase 6: Run and Cement Intermediate Liner Hazards and Contingencies - Swab and surge pressure should be minimized with controlled liner running speeds and by breaking circulation slowly. Excessive swab /surge pressures could initiate HRZ /Kingak instability problems. - Differential Sticking is potentially a problem if lost circulation occurs or if the liner is left stationary across permeable formations. Proper casing centralization and keeping the liner moving will facilitate minimizing the potential for differential sticking.

The 8.4 - 8.6 ppg mud will be 545 psi over balanced to the Sag River and Ivashak formations. Minimize the time the pipe is left stationary while in open hole (making connections, surveying, etc). - A pilot hole will be drilled into the Ivashak formation to test for future sidetrack opportunities. This pilot hole will be P&A'd with cement before sidetrack and drilling the Sag River horizontal well. - A liner running pill will be left in the open hole on the final trip out of the hole to run the slotted liner. 06-06B Permit to Drill -Version 1.0 Page 10 • • Job 9: Run 4-1/2" Production Liner Reference RP • "Modified Conventional Liner Cementing'' RP • Schlumberger Cement Program.
