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.

Submit a well schematic diagram with each 10 well completion report and 10-404 well sundry report when the downhole well design is changed. Item 1 a: Classification of Service Wells: Gas Injection, Water Injection, Water- Altemating -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). Item 28: 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 30: Provide a listing of intervals tested and the corresponding formation, and a brief summary in this box. Submit detailed test and analytical laboratory information required by 20 AAC 25.071.

History of 02 -12B: Well 02 -12B was drilled in July 2007 as a CTD sidetrack targeting Z1B /2A in southern region of DS2. The well was completed with 250' of Z1B and 485' of Z2A perforations. The 3- 3/16" liner lap failed the initial pressure test to 2050 psi (lost 200 psi in 10 min) and a liner top packer was installed. After installing the liner top packer, the liner lap passed a pressure test to 2030 psi. The well is currently shut in for high GOR. In August 2007, borax CNL and STP logs were run to identify the gas source and evaluate potential gas shut -off options. The borax log indicated no channels behind pipe. The STP log showed equal flow contributions from the 2 perforation intervals but a cooling anomaly was detected on the flowing and residual temperature passes at 11,320' in the Z2A perforations indicating a likely source of gas entry. The GOC was predicted in mid -Z2A but many of the offset wells have coned GOC picks. It is likely that 02 -12B is experiencing a comparable coning affect. A CIBP was set at 11,175' MD on 07/07/2008 to shut -off the Z2A perforations at the toe of the well. There are still open perforations from 10,830' to 11,080'. REASON FOR SIDETRACK Since February 2008, the well hasn't flowed leaving the well with no remaining value or well work possibilities. The proposed plan for 02 -12C is to drill a through tubing sidetrack with the SLB/Nordic 2 Coiled Tubing Drilling rig on or around March 26, 2011. The existing perforations will be isolated by setting the 3- 3/16" packer whipstock, as well as the primary cement job. The sidetrack, 02 -12C, will exit the existing 3- 3/16" liner and kick off in Ivishak, tagging HOT in Z1B and drilling 2,075' of lateral with a 2 -3/8" Carbon Liner completion. The following describes work planned and is submitted as an attachment to Form 10 -403. A schematic diagram of the proposed sidetrack is attached for reference. • tv'e ( Cgn o�► 4r L/uyr Q "4er 4: 7 "° s /� 604' 1„ LO'Gvi, t+ / � r7 li e. ef 4 v� l ( *i#CLI - For /H4jic 512 dap W4 Aindowil, �l fr �ptf f /Ace 7# / T f / T j q Qridcli t- c7`P4's apt.

(2) All depths are Bit Depths unless otherwise noted. (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 pownhole Pressure, Vibration and Downhole Weight on Bit), a Directional and Gamma Sub, and a Hydraulic Orienting Sub with a Near Bit Inclination Sensor and Ultra Slim Resistivity Sub. (7) Data presented here is final and has been depth adjusted to PDCL (Primary Depth Control Log from Schlumberger MCNL dated 21-Jun-2007.
