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, Jerry Murphy, at 659 -5102. Sincerely, Torin Roschinger BPXA, Well Integrity Coordinator • i BP Exploration (Alaska) Inc.

The permit to redrill 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 xvith 20 AAC 25 035. Sufficient notice (approximately 24 hours) must be given to allow a representative of the Commission to witness a test of BOPE installed prior to drilling new hole. Notice may be given by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607. ~ild W. jOhnston "-'"~~"~ BY ORDER OF THE COMMISSION dlffEnclosures cc: Department of Fish & Game, Habitat Section w/o encl.

Drilling Hazards/Contingencies · Pore pressure may be as high as 9.5 ppg EMW in the Ugnu (-4800' TVDSS) due to water disposal. Will ensure appropriate mud weight for overbalance. · Tight hole and packing off has been seen in the Seabee and Kingak on previous Y-Pad wells. Mud will be treated with additives to stabilize shales. · P Pad is not an H2S pad. The highest H2S level on the pad is from Y-20 at 70 ppm in 12/95. · Losses have been encountered drilling the Sag River, Shublik and Sadlerochit formations on other P-Pad wells. Pump LCM as necessary to control losses. Disposal · Cuttings Handling: Cuttings should be hauled to the ball mill at CC-2A. Fluid Handling: Haul all drilling and completion fluids and other Class II wastes to CC- 2A for injection. Haul all Class I wastes to Pad 3 for disposal. In addition, haul all cuttings from drilling operations to CC-2A for disposal, except any metal cuttings which will be sent to the North Slope Borough. SUMMARY REDRILL PROCEDURE: Note: The wells' current BHL is no longer economic due to high WC (98%) and low /]I ~.~ total fluid rate. It will be P&A'd by the rig prior to sidetrack operations. 1. Move in drilling rig. Remove tubing down to 9460' MD. 2. Set EZSV at 9450'MD. Bullhead squeeze cement to P&A existing perforations (see separate P&A Sundry). 3. Mill 45' window in 9 5/8" from 9200-9245' MD. Spot cement kickoff plug. 4. Kickoff with 8 1/2" bit/MWD/GR and drill/build to 10629' MD (3' below TSAG) 5. Run and cement 7" liner. 6. Drill out with 6" bit/MWD/GR and TD Zone 4 horizontal section at ,-,16051' MD. 7. Run, cement, and perforate 4 1/2" liner. 8. Complete well with 4 1/2" L-80 IBT-mod tubing & 6 GLMs. Test.
