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 • • BP Exploration (Alaska) Inc.

IreM 1a: Classification of Service Wells: Gas Injection, Water Injection, Water-Alternating-Gas Injection, Salt Water Disposal, Water Supply for Injection, Observation, or Other. Multiple completion is defined as a well producing from more than one pool with production from each pool completely segregated. Each segregated pool is a completion. Irenn 4b: TPI (Top of Producing Interval). ITeM 8: The Kelly Bushing and Ground Levef elevation in feet above mean sea level. Use same as reference for depth measurements given in other spaces on this form and in any attachments. IreM 13: The API number reported to AOGCC must be 14 digits (ex: 50-029-20123-00-00). Ire~a 20: Report true vertical thickness of permafrost in Box 20. Provide MD and ND for the top and base of permafrost in Box 28.

The sidetrack plan is to exit the 01-OlA "main" wellbore from the 9-5/8" casing at ~5,500' MD with an 8-1/2" BHA. The 8-1/2" hole will then be drilled to the top of the Sag River formation at ~9,494' where a 7" drilling liner will be run and cemented. A 6-1/8" production hole will then be drilled building to a final TD of 11,560' MD. A 4-1/2" solid production liner will be run and cemented from TD to 150' back into the 7" drilling liner. The 4-1/2" production liner will be perforated in span of approximately 600'. This well will be completed with a 4-1/2" chrome completion.

The proposed Ol-O1C well lies in a high risk province of the field for lost circulation at faults as documented by the WURD team. Eighteen loss circulation events were encountered in all zones in 12 of the surrounding 32 wells (38%), as detailed below. The worst of these occurred during intermediate casing operations in Shublik or Kingak formations due to incorrect picking of the casing point. If the Sag River casing point is properly identified, the risk for loss circulation is average. No faults are expected to be encoantered by the planned well. Three faults are located to the east of the planned well. The closest of these, which does not penetrate Zone 1 and thus is not shown on the map, is 265 feet from the wellplan. The other two are 420 feet and 520 feet to the east. Two additional faults are located 335 ft and 360 feet west of the planned well. The east and west boundaries of the drilling polygon are thus hardlines. The polygon does not allow for any extension of the well due to faulting to the north and proximity to the OS-07 offtake.
