Commis Anchorage, Alaska 99501 Ancner® Subject: Corrosion Inhibitor Treatments of GPB P -Pad lc/ (2 _ 206 Dear Mr. Maunder, f L Enclosed please find multiple copies of a spreadsheet with a list of wells from GPB P- Pad 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, Gerald Murphy, at 659 -5102. Sincerely, Mehreen Vazir BPXA, Well Integrity Coordinator 0 • BP Exploration (Alaska ) Inc.

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. Notice may be given by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607.

Drilling Hazards/Contingencies · Pore pressure may be as high as 9.2 ppg EMW in the Ugnu (-4545' TVDSS) due to water disposal. Will ensure appropriate mud weight for overbalance. · Gas cut mud has been observed at 7365' TVD SS (Miluveach) and will be controlled with appropriate mud weights. In addition, tight hole conditions have been encountered in the Kingak shales at -7500 TVDSS. Mud weights as high as 10.4 ppg and the addition of shales stabilizers may be required. · P Pad is not an H2S pad. The highest H2S level on the pad is from P-4 at 69 ppm in 12/95. · Losses have been encountered drilhng 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 H 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.
