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 • BP Exploration (Alaska) Inc.

(3) All True Vertical Depths (SSTVD) 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 PDCL (Primary Depth Control Log) provided by Schlumberger dated 28 Dec 2007. (8) Tied to 15-04 at 9600 feet MD (8414 ft. TVDSS) (9) The sidetrack 15-04B was drilled off a permanent whipstock set at 9806 feet MD (8419 feet TVDSS) through a milled window in 4 1/2 inch and 7 inch liner. Top of window 9808 ft.MD (8420 ft.TVDSS) Bottom of window 9816 ft.MD (8427 ft.TVDSS) (10) Baker Hughes INTEQ runs 3 and 4 were used to drill 15-04B PB1. (11) No footage was drilled on run 5. Decision to sidetrack was made while tripping in the hole. (12) Baker Hughes INTEQ run 6 was utilized to open hole sidetrack at 10240 feet MD (8792 feet TVDSS). (13) The interval from 12835 feet to 12865 feet MD (8820 feet to 8818 feet TVDSS) was not logged due to sensor to bit offset at well TD.
