Terrie Hubble, 564-4628 Well Number Permit No. / Approval No. Driuing Engineer: Greg Sarber, 564-4330 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 1 a: 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 ND 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 Iisting 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.

Isolation of the existing perforations will be with a cast iron bridge plug followed by cement from the proposed new coil tubing drilling sidetrack. The CTD side track will target 2A reserves to the southeast of C pad. Short Timing - Due to the lack of availability of equipment needed for two currently permitted wells, this well has moved up the drilling schedule considerably. The expected spud date for the C-126 sidetrack is now September 5, 2009. Due to the limited time to complete the pre rig preparation work and the need to have Sundry approval prior to beginning that work, quick sundry approval is requested from the AOGCC. ~ WELL HISTORY/CURRENT STATUS: C-12A is a 1998 horizontal CTD sidetrack completed in Z2A with 350' of perforations. C-12A began to cycle within six months due to high GOR driven by high gas rates. 60' of Z2A perforations were added closer to the heel in early January 2000 without notable impact. A CIBP was set at 12500' MD to shut off the initial perf sets in April 2000 but didn't have an impact on the GOR trend; drops in both oil and gas rates were observed. The well continued to cycle over the next two years until June 2002 when the CIBP was milled and pushed to bottom. There was a short-lived oil buzz, but the gas rate quickly climbed up to 40 MMCFD, and the well began to cycle again. C-12A is currently twinned with C-11 A but cannot flow commingled due to the flowline gas rate constraint of 58 MMCFD. C-12A has seen minimal on-time since C-11A was drilled in 2003. On April 9-11, 2009 service coil rigged up to re-set the CIBP for a gas shut-off, but they tagged high at 12177' CTM above the top set of perfs. A 1.69" motor and 2.20" mill was used to mill through the obstruction in the 2-7/8" liner but was unsuccessful, most likely due to collapsed liner. Without access to the lateral, C-12A remains shut-in for high GOR. A SCMT log run on 6/6/09 indicated the top of cement behind the 2-7/8" liner is at ~11420' MD, which is below the TSGR aflowing for a cut-and-pull of the liner for a big coil sidetrack. During CTD screening in June 2009, the well passed a MIT-IA to 3000 psi and a MIT-OA to 2000 psi. The PPPOT-T passed but the PPPOT-IC failed despite all LDS functioning. A caliper log run 5/25/09 indicated the tubing is in good-to-fair condition and the 2- 7/8" liner is in good condition. REASON FOR SIDETRACK: C-12A is not a competitive well. It exhibits minimal recharge, and has low remaining value. It has damaged liner with no repair options and can't flow as currently twinned. The pre CTD rig plan is to abandon the existing perforations with a cast iron bridge plug and primary cement job from the new sidetrack liner. , .; , f~.;,~/ v~%~~./ ~ .~ti'ry'P F /E~S F'r"~c',.s '~+'~' ;'`7 ~r~"G'fL'!~ C%C7~~`~tf ~"~~~~~'~~` /PU• ~ ~e:/"+''~G 4''~ ~''^ f ,'7 ' _ - ,ic- G'l,r, . ~,7 x ,, S ?'. ~=9 `j ..',~ ~~ ' ~ ~ G~.S .~` z ' /~'S° • , c~f~l ~% r~, G ~. ~~~"~~'''~ ~/ . ~ • Pre-Rig Operations: (Scheduled to begin on August 15, 2009) 1.

The sidetrack, C-12a, will target Lower Zone 2 / Upper Zone 1 (22P-14P) reserves. This sidetrack will be conducted in two phases. Phase 1: Set whipstock and downsqueeze abandonment cement: Planned for 6/15/98. · C-12 has passed an inner annulus pressure test. The well has been drifted and a Kinley caliper has been run. · A permanent whipstock will be set on ELine at approximately 11,640' MD. · Existing perforations will be abandoned with approx. 20 bbls cement. Abandonment cement will be downsqueezed past the whipstock and will be pressure tested to 1500 psi with AOGCC witness. This procedure is described in more detail in the Form 10-403. Phase 2: Mill Window and Drill Directional Hole: Planned for 6~30~98. Directional drilling coil tubing equipment will be rigged up and utilized to mill the window and drill the directional hole as per the attached plan. Mud Program: - Phase 1: Seawater - Phase 2: FIo-Pro (8.8 - 8.9 ppg) Casing Program: - 2 7/8", 6.16#, L-80, ST-L liner will be run from TD to approx. 10,360' MD and cemented with approx. 20 bbls. cement. The well will then be perforated with coil tubing conveyed guns. Well Control: - BOP diagram is attached. - Pipe rams, blind rams and the CT pack off will be pressure tested to 400 psi and to 4000 psi. - The annular preventer will be tested to 400 psi and 2000 psi. Directional - See attachments. - Kick Off: 11,660' MD (8,764' TVD ss) - TD: 13,051' MD (8,965' TVD ss) - Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. Logging · A Gamma Ray log will be run over all of the open hole section. · Memory CNL will be run in the liner prior to perforating.
