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, Jerry Murphy, at 659 -5102. Sincerely, Torin Roschinger BPXA, Well Integrity Coordinator • • BP Exploration (Alaska) Inc.

This permit to drill does not exempt you from obtaining additional permits or an approval required by law from other governmental agencies and does not authorize conducting drilling operations until all other required permits and approvals have been issued. In addition, the Commission reserves the right to withdraw the permit in the event it was erroneously issued. Operations must be conducted in accordance with AS 31.05 and Title 20, Chapter 25 of the Alaska Administrative Code unless the Commission specifically authorizes a variance. Failure to comply with an applicable provision of AS 31.05, Title 20, Chapter 25 of the Alaska Administrative Code, or a Commission order, or the terms and conditions of this permit may result in the revocation or suspension of the permit. When providing notice for a representative of the Commission to witness any required test, contact the Commission's petroleum field inspector at (907) 659-3607 (pager). Sincerely, Daniel T.

Mud Program: • Well kill: 8.4 ppg brine. • Milling/drilling: 8.6 ppg Flo Pro or biozan for milling, new 8.6 ppg Flo Pro for drilling. Disposal: • All drilling and completion fluids and all other Class II wastes will go to Grind & Inject. • All Class I wastes will go to Pad 3 for disposal. Hole size: 3.75"x4-1/8" (bi-center bits used) Casing Program: fully cemenfed liner • 3-3/16", L-80 6.2# TCII 9816' and - 11,770' and • 2-7/8", L-80 6.16# STL 11,770' and - 13,840' and • A minimum of 65 bbls 15.8 ppg cement will be used for liner cementing. (Assuming 4-1/8" bit size and TD C 13,840', with 40% excess in the open hole interval) • TOC planned at 9900' Well Control: • BOP diagram is attached. • Pipe rams, blind rams and the CT pack off will be pressure tested to 250 psi and to 3500 psi. • The annular preventer will be tested to 250 psi and 2500 psi. Directional • See attached directional plan. Maximum planned hole angle is 94 deg • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property - 10,570' ft. • Distance to nearest well within pool - 1,020 ft. (Y-37A) Logging • MWD directional, Gamma Ray, and resistivity will be run over all of the open hole section. • A cased hole MCNUGR log will be run. • The well is currently an injector and will be sidetracked within in the current injection zone. A cement bond log is not planned for this well. The Y-05A segmented bond log dated 25- AUG-95 will be used to demonstrate the parent well isolation. Hazards • The maximum recorded H2S level on Y pad is 200 ppm on well Y-28. • Lost circulation risk is high Reservoir Pressure • Res. press. is estimated to be 3240 psi at 8800'ss (7.0 ppg EMW). Maximum surface pressure with gas (0.10 psi/ft) to surface is 2360 psi.
