Terrie Hubble, 564 -4628 Well Number Permit No. / Approval No. Drilling Engineer: Zach Sayers, 564 -5790 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 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.

The Sag River is known to be a relativity weak formation compared to the Kingak, therefore we had concerns about the ECD's while circulating the cement job all the way up above the Schrader Bluff. To mitigate the risk of dropping the bottom out of this well while pumping the cement job a two stage cementer was ran below the Schrader Bluff formation to ensure cement coverage across these sands. Both stages were pumped with full returns.

For the planned drilling of this well, 20" conductor casing will be run and cemented to -80' at this surface location which is located between wellheads W- 16 and W -17. The basic drilling plan will include a 12 - /a" surface hole to 3,464' MD (SV1) where 9-%" surface casing will be run and cemented to surface. An 8 -3/4" intermediate hole will then be drilled from the 9 -%" casing shoe to the top of the Sag River formation -9,377' MD where a 7 ", 26.0# intermediate casing string will run and cemented with the proposed cement top to be 500' MD above the MA sandstone. A 6 -%8" production interval will then be drilled with the final well TD at -13,308' MD where a 4-1/2", 12.6# solid liner will be run and fully cemented. The planned completion for this well will include a 4 -1/2", 12.6# tubing, with a single permanent packer. The W -56 well is currently scheduled to be drilled by Nabors 7ES with a spud date of December 1 2009. Please refer to the additional data within this request for specific well details and do not hesitate to call if I additional information is required.

After } drilling past the larger rocks and wood sections, the flow paddle will be put back in the flow line. DISPOSAL: • No annular injection in this well. • Cuttings Handling: Cuttings generated from drilling operations will be hauled to grind and inject at DS -04. Any metal cuttings will be sent to the North Slope Borough. • Fluid Handling: Haul all drilling and completion fluids and other Class II wastes to DS -04 for injection. Haul Class I waste to DS -04 and /or Pad 3 for disposal. Contact the GPB Environmental Advisors (659- 5893) for guidance. W -56 Permit To Drill Page 8 1 Drilling Hazards and Contingencies POST THIS NOTICE IN THE DOGHOUSE I. Well Control A. The Schrader Bluff sands in this fault block are expected to be pressured from 5.6 to 8.7 ppg EMW. The lvishak is expected to be pressured from 6.7 to 7.6 ppg EMW. 1I. Lost Circulation /Breathing A. Risks of lost circulation for the proposed W -56 Ivishak well are Moderate. Lost circulation is considered moderate at the fault crossings and unexpected fracture zones. The Shublik breathing phenomenon may occur on this well, however all lessons learned have been applied within the plan to mitigate this potential. Follow the RP guidelines for dealing with it if it occurs. III.

Stuck Pipe A. Recent W Pad wells have experienced tight hole and lost circulation with drilling and running casing in Permafrost interval. The Tesco CDS casing running tool will be used to address this problem for 9-%" casing B. There could be slight differential sticking across the open hole while running the 7" casing. Keep the casing moving as much as possible and follow the centralizer program to help with standoff. VI. Hydrogen Sulfide A. W Pad is not designated as an H site, however Standard Operating Procedures for H precautions should be followed at all times. H levels across the pad are typically in the 10 -30 ppm range based on the latest samples taken. The highest reading was 60 ppm of W -01A on 8/16/05. VII. Faults Formation Where MD TVDSS Est.

VIII. Anti - Collision Issues A. Reference Anti - collision report in directional plan. W -56 directional plan has a close approach to W- 03 at 9,685' MD (W -03's wellbore). The ctr -ctr distance is 84', but the allowable deviation is 45'. W- 03 has been sidetracked above the collision risk depth. W -03A is a MI Injector well. W -03's 5 -1/2" liner has been cemented to a depth of 9,061' MD. If collision occurs, PROD BHA will drill through 5 -Y2" casing and cement.
