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 la: 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 K -05C. Well K -05C is a July 2004 horizontal CST with 1100' of Z1A perfs. Initial production was high with low GOR. Within 2 weeks gas rates increased and production levelled out. The well remained on full time until May 2005 when it reached marginal GORs and was shut in. Well K -05C was then cycled for the following 4 years, showing reasonable recharge and ontime over that period. By Dec 2008, K -05C began showing diminishing recharge and it was thought that without surveillance which would lead to remedial well work, the well would likely become shut in full time. As a result, a PPROF /MCNL was run. Based on the MCNL log and interpretation of the PPROF, a CIBP was set at 10,150' and 50' of Zone 1B were perfed in the heel of the well in Sept 2009. The well came back at high initial rates and returned K -05C to full time production. The well remained online for 5 months before hitting marginal GORs and was once again shut in. Since Jan 2010, K -05C has seen 28% ontime, the majority of it coming as a PBGL source well for new sidetrack K -11A. Reason for sidetrack. K -05C is no longer a competitive producer, and there are no remaining wellwork options. The proposed sidetrack will access reserves in the southern portion of K -pad. Proposed plan for K -05D is to sidetrack with a Coiled Tubing Drilling rig on or around July 15 2011. The existing perforations will be isolated by a 3- 3/16" packer whipstock and the liner cement. The sidetrack, K- 05D, will exit the 3- 3/16" and 4W liners into Zone 2. The -3000' lateral will target Z1A reserves. This sidetrack will be completed with a 2 -3/8" liner in the production interval. The following describes the work planned and is submitted as an attachment to Form 10 -403. A schematic diagram of the proposed sidetrack is attached for reference. / COI•Gvr. Y' a /f 7howt f !

ITEM 1a: 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 elevation in feet above mean low low water. 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: True vertical thickness. 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 26. (Submit a separate form for each additional interval to be separately produced, showing the data pertinent to such interval). ITEM 26: Method of Operation: Flowing, Gas Lift, Rod Pump, Hydraulic Pump, Submersible, Water Injection, Gas Injection, Shut-In, or Other (explain). ITEM 27: If no cores taken, indicate "None". ITEM 29: List all test information. If none, state "None".
