Sondra Stewman, 564 -4750 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 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.

F -27A was a 2005 coil sidetrack targeting upper Zone lA/1B sands after the parent well, F -27 gassed out. The parent perfs in Zone 1 were squeezed off for the sidetrack, and F -27A was planned and drilled above the MHO to maximize standoff from the GOC. F -27A was completed with a 3 -1/2" x 3- 3/16" x 2 -7/8" tapered solid liner that was cemented and ties back into the existing 4 -1/2" tubing. A total of 1105' of perforations were shot in the 2 -7/8" liner, targeting Zone IA/1B. The majority of the perfs ( -720') were shot in Zone IA, throughout the length of the completion - Zone 1B was encountered in the toe of the well. After the sidetrack, F -27A produced at low GOR until a prolonged shut -in period in 2008. When the well was brought back online, the gas rate increased with a decline in oil rate, quickly making the well uncompetitive, with high GORs. The well was shut in for the majority of 2009 to determine if it would heal or show signs of cycling ability. However, when POP'd in early 2010, F -27A showed signs of elevated gas rate and no healing or cycling ability. REASON FOR SIDETRACK Given the very low oil rates and high GOR, F -27A is a good candidate for a coil sidetrack. The proposed sidetrack will target 1600' of Zone 1 and will provide additional offtake in a — 25acre drainage target in central F -Pad. The proposed plan for F -27B is to drill a through tubing sidetrack with the SLB/Nordic 1 Coiled Tubing Drilling rig on or around November 27, 2010 The existing perforations will be isolated beneath a packer whipstock set in the 3- 3/16" tubing. The sidetrack, F -27B, will exit the existing 3- 3/16" liner and kick off in zone, intentionally drilling just in the MHO/HOT for the first portion of the wellbore to maximize gas standoff and leave options for future sidetracks. 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. co1u (,Q� ��� @ �, na f s'o d ¢ Pre -Rig Work: (scheduled to begin November 10, 2010) he0l,''/ OVV-f a I Pa r f 6hvr- 1.

IreM 1a: 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. IreM 4b: TPI (Top of Producing Interval). IreM 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. IreM 13: The API number reported to AOGCC must be 14 digits (ex: 50-029-20123-00-00). IreM 20: True vertical thickness. IreM 22: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool. IreM 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). IreM 26: Method of Operation: Flowing, Gas Lift, Rod Pump, Hydraulic Pump, Submersible, Water Injection, Gas Injection, Shut-In, or Other (explain). IreM 27: If no cores taken, indicate "None".

F-27A File 205-??? Fm: Jack Hartz J~ Subj : F-27 Sidetrack Evaluation State of Alaska Oil and Gas Conservation Commission August 9, 2005 F-27 was a zone 1B/2A producer drilled in 1986 as an 80-acre infill well. The well has produced 7.45 MMBO with GOR increasing from SGOR to approximately 46 MCF/Bbl. The well has reached marginal GOR and attempts to cycle it have not proven successful. Decline analysis (attached) indicates approximately 1.5-3 million barrels reserves left in the drainage area, assuming unconstrained production. A conservative exponential decline yields 1.5 MMBO and hyperbolic 3+ MMBO remaining reserves to 100 BOPD limit. F-27A is being sidetracked to the same in zone 1 B geologic level as F-27. The well will be steered to be near the base of the zone 1 B to optimize offtake. The well will have 2000+ feet of horizontal hole, a cemented liner and approximately 1000' of perforations. The peroforated interval will be 750' at its furthest from the original well bore and likely will be closer depending on where perforations are placed. Conclusion: F-27A is being complete within the drainage area of F-27 and will be recovering remaining reserves of 1.5-2.5 MMBO.
