Terre Hubble, 564-4628 Well Number Permit No./Approval No. Drilling Engineer: Amanda Rebol, 564-5543 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 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.

The wrap has been pressure tested and there was no evidence of a continued leak at surface. The well has been reclassified as Operable.

Directional • See attached directional plan. Maximum planned hole angle is 94 deg • Magnetic and inclination surveys will be taken every 30 ft.No gyro will be run • Distance to nearest property line—9580' • Distance to nearest well within pool—679' (F-04B;this point occurs as the planned F-28B trajectory is exiting the -- liner in the parent wellbore. Anticollision Summary • No anti-collision issues Logging • MWD directional and GR will be run over all of the open hole section. Hazards — • F-Pad is considered a high-level H2S pad.The maximum recorded H2S level on F-Pad is 160ppm on F-24 (4/15/2007). More recent readings on nearby surface and bottomhole locations are lower,in the 10-12ppm range, with the most recent parent wellbore reading at l0ppm on 5/12/2010. Take all necessary precautions while working on an H2S site. • Lost circulation risk is considered low;there are no fault crossings planned while drilling this well,and there are no significant lost circulation events in surrounding wellbores targeting the same zone. Even though there are no losses anticipated,always monitor for potential losses while drilling. Reservoir Pressure • Reservoir pressure is estimated to be 3,180 psi at 8,800'TVDss(6.95 ppg EMW). Maximum surface pressure with gas(0.10 psi/ft)to surface is 2,300 psi.
