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 • • BP Exploration (Alaska ) Inc.

I apologize for the poor wording in the original letter. The TIFL was preformed after placing the wet online, which warms the gas lift valves allowing a better seating action on the check valves in the orfice valve. The TIFL was a pass from the aspect that the tubing pressure exceeded the IA pressure by j over 1000 psi, the fluid level did not change in the IA, and the pressure in the IA decreased by 30 psi the next day. If you would like to discuss the job, please give myself or Torin a call, as we are doing change out in Anchorage Tuesday morning, and he will be on the slope tomorrow night.

There is a hole in the tubing at 5,755 ft MD. The well is currently floWing. The purpose for requesting this variance is to allow time to evaluate and execute any wellwork that will improve the performance in the Dec, 96 timeframe.

Dumped three E-line bailer loads, which should leave TD at 11,392. Dumped each bailer at 3' from previous TD/cement top. Did not attempt to tag cement. Note: First two bailers came out clean. Final bailer was covered with a cement sheath. It appears that.some cement got strung uphole. Note: IA equalized with SIWHP. Pesos notified and reported that well has done this before.

Mr. A. E. Leske Manager Reservoir Development Sohio Alaska Petroleum Company P. O. Box 6612 Anchorage, Alaska 99502-0612 Dear Mr. Leske.. The Alaska Oil and Gas Conservation Commission received your request, dated October 16, 1984, to substitute static surveys for transient pressure surveys on Prudhoe Bay Unit Wells A-23, B-9, and Y-8. As operator of the western area of the Prudhoe Bay Unit Sohio Alaska Petroleum Company is required to take an annual transient pressure survey in each of the governmental sections where the A-23, B-9, and Y-8 wells are located. It is stated that. all three wells are shut-in, that transient pressure surveys are impractical in this situation and static pressure surveys will provide adequate pressure data for reservoir monitoring. The Commission is in agreement with these facts. By this letter, the Alaska Oil and Gas Conservation Commission hereby waives the requirements of Rule 6(d) of Conservation Order No. 165 for the Prudhoe Bay Unit Wells A-23, B-9, and Y-8 for the calendar year 1984 and will accept static pressure surveys on the wells. This action is taken pursuant to Rule 2 of Conservation Order No. 192. Yours very truly, Harry W.
