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. Sincerely, Torin Roschinger BPXA, Well Integrity Coordinator • BP Exploration (Alaska) Inc.

Job 7: Drill 6 1/8" Production Hole Interval Planned Job Time Planned Job Cost 161.8 hours $840,000 Reference RP • "Standard Operating Procedure: Leak-off and Formation Integrity Tests" • "Prudhoe Bay Directional Guidelines" RP Issues and Potential Hazards - KICK TOLERANCE: In the worst-case scenario of 3,250 psi pore pressure in the Ivishak, a fracture gradient 9.3 ppg at the 7" liner shoe, and 8.4 ppg mud in the hole, the kick tolerance is infinite. 15-026 Rotary Sidetrack Page 8 • ~ - The above kick tolerance is based on an FIT of 9.3 ppg EMW, contact the ODE if this EMW is not reached. - The directional plan has the wellbore entering the Sag River at 33°, the angle will then be dropped to 24° through the Zone 3 conglomerate. The well will then be landed in Zone 1 A and drilled horizontally with atoe-up into Zone 1 B prior to TD at 12,563' MD - The production interval is planned to be drilled with two bits. An insert bit will be utilized to drill the conglomerate and land the well in Zone 1 B, a PDC bit will then be used to drill the horizontal section. - 15-026 is prognosed to cross one fault in Zone 2, 10975'-11125' MD. Lost circulation events recorded from the surrounding wells are; 15-23A (30 bbls), C-31 (3900 bbls at 8552 ft), and 3 losses were recorded in C-31 A (total of 940 bbls, at reservoir level). None of these events were associated with fault crossings. No losses occurred in the parent well and no mapped faults are crossed by the proposed well, thus the risk of lost circulation events should be slightly lower than average.
