Dear Mr. Maunder, Enclosed please find multiple copies of a spreadsheet with a list of wells from GPB DS- 02 that were treated with corrosion inhibitor in the surface casing by conductor annulus. 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 P • . BP Exploration (Alaska) Inc.

Item 13: 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. Item 4b: TPI (Top of Producing Interval). Item 8: The Kelly Bushing and Ground Level 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. Item 13: The API number reported to AOGCC must be 14 digits (ex: 50-029- 20123 -00 -00). Item 20: Report true vertical thickness of permafrost in Box 20. Provide MD and TVD for the top and base of permafrost in Box 28. Item 23: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool. Item 24: If this well is completed for separate production from more than one interval (multiple completion), so state in item 1, and in item 23 show the producing intervals for only the interval reported in item 26. (Submit a separate form for each additional interval to be separately produced, showing the data pertinent to such interval). Item 27: Method of Operation: Flowing, Gas Lift, Rod Pump, Hydraulic Pump, Submersible, Water Injection, Gas Injection, Shut -In, or Other (explain).

Maximum anticipated surface pressure from the Ivishak with a full column of gas from TD to surface is 2,530 psi. We will be utilizing Nabors' 5000 psi four preventer stack (3 rams and an annular). The BOPs will be tested to 3500 psi. For the planned drilling of this well, an 8 -1/2" intermediate hole will be drilled from a KOP in the 9 -5/8" casing at -5816' MD to the top of the lvishak formation -8,836' MD where a 7 ", 26.0# intermediate casing string will run and fully cemented. A 6 -' /8" horizontal production hole will then be drilled in zone 1 to a final well TD at -11,678' MD where a 4 - ", 12.6 #, 13 -Cr liner will be run to TD and cemented. The planned completion for this well will include a 4 - ", 12.6 #, 13 chrome tubing string with gas lift mandrels and a permanent production packer. All wells passed the major risk classification with the exception of 02 -22A at KOP. There is no risk to personnel or environment if an intersection occurred Please find attached the DS02 -22B Well Plan Summary, directional plan and proposed completion diagram.

Safety concerns and spacing limitations with the wellhead height and tubing spool preclude us from installing a spacer spool in the three -ram drilling BOP stack. Disposal: • No annular injection in this well. • inject Handling: Cuttings generated from drilling operations will be hauled to grin d and � ect at DS -04. Any metal cuttings will be sent to the North Slope Borough. • Fluid Handling: Haul all drilling and completion fluids and other Class II wastes to DS -04 for injection. Haul Class I waste to DS -04 and /or Pad 3 for disposal / Contact the GPB Environmental Advisors (659 -5893) f /guidance. Fault Prognosis: The planned well is expected to cross one small fault in the lower Kingak near 8750 ft MD, just above the Sag River. This fault, plus the lack of a Jurassic 'B' marker in this area will necessitate heightened care in picking the intermediate casing point. Additional small north -south trending faults are located 240 ft to the west and 260 ft to the east of the planned well. The polygon lines are hardline in these directions. 2 -22B Sidetrack Page 6 DRILL AND COMPLE PROCEDURE SUMMARY Pre -Riq Operations: 1.
