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, Anna Dube. Sincerely, Torin Roschinger BPXA, Well Integrity Coordinator ~ r BP Exploration (Alaska) Inc.

Drilling Engineer: Mel Rixse, 564-5620 INSTRUCTIONS GENERAL: This form is designed for submitting a complete and correct well completion report and log on all types of lands and leases in Alaska. Submit a well schematic diagram with each 10-407 well completion report and 10-404 well sundry report when the downhole well design is changed. ITeM 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. 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 22: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool. ITEM 23: 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 28. (Submit a separate form for each additional interval to be separately produced, showing the data pertinent to such interval). ITeM 28: Method of Operation: Flowing, Gas Lift, Rod Pump, Hydraulic Pump, Submersible, Water Injection, Gas Injection, Shut-In, or Other (explain). ITeM 27: Provide a listing of intervals cored and the corresponding formations, and a brief description in this box. Submit detailed description and analytical laboratory information required by 20 AAC 25.071. ITeM 29: Provide a listing of intervals tested and the corresponding formation, and a brief summary in this box.

November 15, 2008 15-15C - Coiled Tubing ~ing Mud Program: • Well kill: 8.6 ppg brine • Milling/drilling: 8.6 ppg Flo Pro or biozan for milling, new 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: 4-1/8" Casing Program: • 3-1/2", 8.81 #, L-80, STL connection solid liner - 10,500'MD - 10,600' MD w/ liner top packer. • 3-3/16", 6.2#, L-80, STL TC-II connection solid liner - 10,600'MD - 11,400' MD. • 2-7/8", 4.7# , L-80, STL connection Solid liner - 11,400'MD - 12,915' MD. • A minimum of 25.7 bbls 15.8 ppg cement will be used for liner cementing.

Directional • See attached directional plan. Max. planned hole angle is 90 deg. • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property - 19,300 ft. • Distance to nearest well within pool - DS07-16A C«~ 1300ft. Logging • MWD directional, Gamma Ray, and Resistivity will be run over all of the open hole section. • A cased hole MCNUGR/CCL log will be run. Hazards • The maximum recorded H2S level on DS15 is 15-20C 40 ppm 7!1/2006. • Lost circulation risk is moderate. • Additional 2 days planned because of reduced ROP. Reservoir Pressure • The max res. press. is estimated to be 3300 psi at 8800'ss (7.2 ppg EMW). • Max. surface pressure with gas (0.10 psi/ft) to surface is 2420 psi. el Rixse CTD Drilling Engineer cc.

(2) All depths are Bit Depths unless otherwise noted. (3) All True Vertical Depths (TVDSS) are Subsea corrected. (4) All Formation Evaluation data is realtime data. (5) Baker Hughes INTEQ utilized CoilTrak downhole tools and the Advantage surface system to log this well.. (6) Tools ran in the string included Casing Collar Locator, an Electrical Disconnect and Circulating Sub, a Drilling Performance Sub (Inner and Outer Downhole Pressure, Vibration and Downhole Weight on Bit), a Directional and Gamma Sub, and a Hydraulic Orienting Sub with a Near Bit Inclination Sensor. (7) Data presented here is final and has been depth adjusted to a PDC (Primary Depth Control) log from MWD 15-15C. This well was depth shifted (OHMM) above the Kick Off Point of 10922 feet MD carrying the final shift from 10922 feet to the bottom logged interval per Doug Stoner with BP Exploration (Alaska), Inc. (8) The sidetrack was drilled from 15-15A through a milled window in a 4 1/2 inch liner. Top of window 10763 ft.MD (8750 ft.TVDSS) Bottom of window 10772 ft.MD (8755 ft.TVDSS) (9) Tied to 15-15A at 10756 feet MD (8746.2 feet TVDSS). (10) The interval from 12250 feet to 12300 feet MD (8898.4 feet to 8898.5 feet TVDSS) was not logged due to sensor to bit offset.
