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 altemate, Gerald Murphy, at 659 -5102. Sincerely, Mehreen Vazir BPXA, Well Integrity Coordinator • • BP Exploration (Alaska) Inc.

NOTES: Excess non-hazardous fluids developed from well operations will be pumped down the annulus of an offset well. The annulus will be left with a non-freezing fluid during any extended interruption in the pumping process. The annulus will be sealed with cement followed by Arctic pack upon the completion of the pumping process. The Cretaceous interval (4800'TVD - 6500' TVD) is expected to be over- pressured by 100 - 150 psi due to water injection at DS-4. A minimum mudweight of 9.5 ppg will be maintained while drilling this interval. The drilling fluid program and fluid surface system will conform to the regulations set forth in 20AAC25.033. Maximum surface pressure of 3100 psi is based on a BHP of 3800 psi at 8956' TVD. The wells within 200' are' L4-30-178' away 500 TVD/500 MD L4-31-197' away 100 TVD/100 MD L4 is an H2S pad. Ali appropriate precautions will be taken during the drilling of L4-36.
