The well was originally completed as a producer, but was converted to an injector in 2013 thinking that it would support the other Alapah producer NK-26 and it’s subsequent sidetrack NK-26A. Recent studies have shown that the two wells are in isolated reservoir blocks, and that NK-25 injection is not supporting NK-26A. An AOGCC witnessed MIT-IA passed 2,909 psi on 11/6/2022. Objective: Convert NK-25 from an Injector to a Producer within the same pool (Lisburne Oil Pool). Current Bottom Hole Pressure:4,884 psi at 9,115’ TVDss (top perf) Max.

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

Survey Program: Surface - 8,800' Single shot MWD surveys; if magnetic interference is detected, take gyro single shots. Surface - 8,800' In-hole reference gyro; run gyro as deep as possible. 8800' - TD MWD surveys Surface - TD Gyro--Gyrodata continuous mode--during completion Drilling Hazards/Risks Background The Lisburne group consist of two carbonate formations--the Wahoo (upper) and Alapah (lower). The Wahoo is the primary reservoir in the Lisburne field, however an unconformity has truncated it in this region. The only Lisburne well to produce from the Alapah is NK-26, which lies about 3400' west of the NK-25 planned location. NK-26 was completed in the Alapah-C and had an initial reservoir pressure of 4400 psi at 9250' ss (9.1 ppg EMW). NK-26 has produced over 1.4 MM STBO and the pressure in the Alapah-C is currently estimated at 3800 psi at 9250' ss (7.9 ppg EMW). h's assumed the formation pressures encountered in NK-25 will be the same as currently estimated in NK-26. The Alapah-C is depleted (7.9 ppg EMW), but the Alapah B and A zones are most likely at original pressure (9.1 ppg EMW). The maximum anticipated surface pressure (MASP) is 3500 psi--based on a gas gradient applied to the original reservoir pressure in the Alapah-B. Lost circulation was encountered after penetrating porous intervals in the Alapah-C while drilling with a 9.9 ppg mud weight. The losses were controlled with high concentrations of LCM. 4/8/97--LW NK-25 (L6-25) Well Plan ~._~nmary H2S NK-26 has tested as high as 18 ppm H2S. Lost Circulation The geological prognosis calls for drilling from the HRZ into the Alapah-C horizon. It's anticipated the top of the C zone will be fairly fight, however if there is any porosity enhancement in the upper section, lost circulation may occur. To minimize the chances of this occurring, the well plan calls for setting the 9 5/8" casing through the HRZ into the top of the Alapah formation. This will allow for drilling the HRZ with an adequate mud weight (_+10.4 ppg) for wellbore stability, but lowering the mud weight (_+9.3 ppg) prior to drilling the porous intervals in the Alapah-C. In addition the mud will be pretreated with sized calcium carbonate to act as bridging agents. Unmapped low-throw faults may be present and may cause lost circulation. Differential Reservoir Pressure Differential reservoir pressures are likely to be encountered. The Alapah B and A zones are assumed to be at original pressure--9.1 ppg EMW, and a _+750 psi differential pressure between these and the Alapah-C is likely. Close Approaches NK-26 passes SSD's flowing well criteria, but the allowable deviation from the plan is less than 8' at 500' md. However, if NK-26 is shut-in, the allowable deviation increases to 13'. Therefore, the well will be shut-in at the SSSV, until surface casing is set. Well Control: Well control equipment consisting of 5000 psi WP pipe rams, blind rams, and annular preventer will be installed and is capable of handling maximum potential surface pressures.
