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.

THIS WELL WAS DRILLED FROM A WHIPSTOCK IN THE 2-35A WELLBORE. THE TOP OF THE WHIPSTOCK WAS AT 10698'MD/8952'TVDSS. THE WHIPSTOCK WAS POSITIONED AND THE WINDOW WAS MILLED PRIOR TO MWD RUN 1. 4. MWD RUNS 1-5 COMPRISED DIRECTIONAL, DUAL GAMMA RAY (GM) UTILIZING GEIGER- MUELLER TUBE DETECTORS, AND ELECTROMAGNETIC WAVE RESISTIVITY PHASE-4 (EWR4). SEXP DATA FOR MWD RUNS 1-3 ARE NOT PRESENTED DUE TO DATA CORRUPTION. UPHOLE SGRC TIE-IN DATA WERE MERGED WITH MWD DATA FROM RUN 1. 5. MWD RUNS 6-8 COMPRISED DIRECTIONAL AND NATURAL GAMMA RAY (PCG), UTILIZING SCINTILLATION DETECTORS. 6. LOG AND MERGED DIGITAL DATA (LDWG) ONLY WERE SHIFTED TO A SCHLUMBERGER CASED HOLE GAMMA RAY LOG RUN IN 2-35B ON 9 FEBRUARY 2006.
