Once the commission is satisfied that Doyon 25 meets expectations regarding BOP testing then it will fall to the standard default test schedule. I agree that the AOGCC inspectors may be able to see much of the rig before leaving Doyon's yard. I will pass that on to Jim Regg and the inspectors. Hope that clarifies your questions.

We should be on a 7 day BOP test cycle until we complete the final P&A and decomplete work on the K-10B well (this is after we have set and tested the EZSV in the existing 9-5/8" casing at-3250' MD) and then on a 2 week BOP test cycle through the actual sidetrack work on the K-10C well. 3. By CC of this e-mail, the Doyon 25 Wellsite Leaders to give the Inspectors ample notice of the initial BOP test so that they can have a complete walk-through of the rig at that time. If you have any questions or concerns, please advise.

If so,the BOP test frequency will be 7 days instead of 2 weeks. The are no other PTD changes that would need to be addressed as we have the BOPE specs on file here. The Inspectors will also require a walkthrough when the rig is fully set before spudding the first well. Make sure they are notified well in advance to make arrangements. The diverter variance requested has been approved (dealing with the spacer pipe between annular and knife valve outlet).

This permit to drill does not exempt you from obtaining additional permits or an approval required by law from other governmental agencies and does not authorize conducting drilling operations until all other required permits and approvals have been issued. In addition, the Commission reserves the right to withdraw the permit in the event it was erroneously issued. Operations must be conducted in accordance with AS 31.05 and Title 20, Chapter 25 of the Alaska Administrative Code unless the Commission specifically authorizes a variance. Failure to comply with an applicable provision of AS 31.05, Title 20, Chapter 25 of the Alaska Administrative Code, or a Commission order, or the terms and conditions of this permit may result in the revocation or suspension of the permit.

The perforations were P&A'd and the , tubing was jet cut in January 2006 (Approved Sundry Permit Number 305-364). The sidetrack plan for the K-10C includes the following during pre-rig operations: lay in a 1000' cement plug in the tubing and the IA. During rig operations the 4-1/2" tubing will be pulled from the jet cut at approximately 4275' MD. The whipstock exit from the 9-5/8" casing is estimated at 3250' MD and will be milled using an 8-1/2" milling assembly. The 8-1/2" hole will be drilled to the top of the Sag River where a 7" drilling liner will be run and cemented with a 1,000' tail of 15.8 ppg class G cement. The production hole will be drilled with a 6-1/8" BHA initially penetrating through the Ivishak into the Kavik. An openhole sidetrack will then be performed in Zone 2 of the Ivishak and building to horizontal in Zone 1A. The well will then run horizontally through the Ivishak formation to TD at 15,001' MD. The liner will be a 4-1/2" L80 IBT-M solid, cemented and perforated liner and the tubing will be 4-1/2" 13Cr-85 Vam-Top, tied into the top of the production liner.

Based upon calculations below, BOP equipment will be tested to 3,500 psi. BOP regular test frequency for B-13B will be 14 days during drilling phase and 7 days during decompletion and surface casing work.

Safety concerns and spacing limitations with the wellhead height and tubing spool preclude us from installing a spacer spool in the three-ram drilling BOP stack. 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 all Class I waste to Pad 3 for disposal. K-10C Permit to Drill Application Page 6 Drilling Hazards and Contingencies POST THIS NOTICE IN THE DOGHOUSE I. Well Control A. The Ivishak in this fault block is expected to be under-pressured at 7.36 ppg EMW. This pressure is estimated based on offset well pressures. 3500 psi test pressure is in accordance with the RP for Prudhoe production well casing tests for producing wells. Interval PSI (EMW) MD(ft) TVDss (ft) Ivishak Z1 A 3300 (7.36) 15003 8614 B. Be aware of possible Cretaceous overpressure. Over-pressure from the produced water injection in the UGNU sands is expected. The maximum anticipated pressures are approximately 9.2 ppg. C. Tight hole, swabbing, and bridges, requiring normal working and/or washing and reaming occurred on most wells throughout B Pad. Most of these incidents were handled in routine operations. II. Lost Circulation/Breathing A. K-Pad is in the med risk zone for LC according to the WURD lost circulation study and the seismic data indicates that we may have one fault crossing in Z1A in the lateral part of the sidetrack (estimated throw of 40ft). III. Kick Tolerance/Integrity Testing A. With the planned 10.6 ppg mud weight, the kick tolerance for the intermediate section is 63.0 bbls. With the planned 8.7 ppg mud weight, the kick tolerance for the production section is infinite.The FIT/LOT will prove up adequate formation strength for expected ECD's. B.
