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).

putting the Gyro survey about 40ft deeper in the hole. The survey indicated that we could drill ahead another 30 ft with no dog legs if needed. We tripped in hole with a drilling assembly and drilled the 30 ft, then POOH. We tripped in hole with the UBHO assembly again on bottom and found that we had sufficient dog legs to drill ahead to TD with no anti - collision problems. We are currently drilling ahead to the TD of this section.

Nabors 9ES is on V -1231 drilling the surface hole at 978' MD. Due to anti - collision concerns with V -106, we have decided to pump a balanced plug of cement in V -123i, and kick off higher in the well, as well as shut in the well V- 106 sub - surface. Procedure as is follows: Rig Operations: 1. TIH to TD with 5" DP with UBHO sub on top of a short mule shoe assembly. 2. RU and Run Gyro survey. Call town with results. 3. Lay a 200' MD balanced plug of cement from TD to -750' MD w/ 250% excess. 4. POOH and LD 5" DP. 5. RIH with drill collars to displace fluid to 100' MD, and bleed out all fluid from surface equipment. 6. POOH and LD drill string. 7. Skid rig away from V -1231 while leaving diverter installed. Wells Group Operations: 1. RU slickline on V -106 and set a pump out plug in the X- Nipple. 2. Bleed off pressure from V -106. 3. Shut in V -106 at surface. Rig Operations: 1. Skid rig back onto V -123i. 2. Clean out conductor and drill ahead. Please don't hesitate to call or email me if any more information is needed.

The current configuration puts the top packer 511' MD above the top perforation. The perforations in the 7" casing are in a horizontal section in the Kuparuk C4. The completion will require wire line access for future well operations, thus pushing the production packer higher in the well. The most recent estimate is 8,689' MD for the top most packer. It is requested that we are given a dispensation from 20AAC 25.412 to set this packer at or below 8,600' MD to allow for variance of actual drilling depths.

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 V -04 and V -106i. The basic drilling plan will include a 13 -1" surface hole to 3,281' MD (SV1) where 10- surface casing will be run and cemented to surface. An 9- intermediate hole will then be drilled from the 10 -3/4" casing shoe to the Kuparuk C2E formation —9,876' MD where a 7 ", 26.0# intermediate casing string will run and cemented ' with the proposed cement top to be 1,000' MD below the surface casing shoe. A 6 - %8" production interval will then be drilled with the final well TD at —11,750' MD where a 3 -1 ", 9.2# solid liner will be run and fully cemented. The planned completion for this well will include a 4-1/2", 12.6# x 3-1/2" 9.2# tubing, with I -wire and two packers. The V -123i well is currently scheduled to be drilled by Nabors 9ES with a spud date of December 1 2009.

V -123i Permit To Drill Page 5 WELL CONTROL • The 13 -'/2" surface hole will be drilled with a 16" diverter. The 9-%" intermediate and 6 -W production hole will use well control equipment consisting of 5,000 psi working pressure pipe rams (2), blind /shear rams, and an annular preventer will be installed and is capable of handling the maximum potential surface pressures. Annular preventer will be tested to 2,500 psi. Based upon calculations below, BOP equipment will be tested to 4,000 psi. BOP regular test frequency will be 14 days with a function test every 7 days.

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. V -123i Permit To Drill Page 6 Drillij Hazards and Contincncies POST THIS NOTICE IN THE DOGHOUSE I. Well Control A. The Schrader in this fault block is expected to be pressured from 6.9 to 8.7 ppg EMW, while the Kuparuk in this fault block is expected to be pressured from 8.8 to a 9.6 ppg EMW. II. Lost Circulation /Breathing A. Risks of lost circulation for the proposed V -123i Kuparuk well are moderate at Fault #2. This well plan has been designed to mitigate these risks with standoff from the 7" casing point. III.

Stuck Pipe A. 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. V. Hydrogen Sulfide A. V 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 30 -100 ppm range based on the latest samples taken. The highest reading was 300 ppm of V -117 in April '07. VI.
