Isolation of the existing perforations with a cast iron bridge plug followed by a new coil tubing drilling sidetrack is proposed. The CTD side track will be a high angle step-out well to target Z1 A/1 B reserves north and east of C Pad. WELL HISTORY/CURRENT STATUS: E-15C is a June 2006 horizontal RST GD producer with 1230' Z1A. The well produced fulltime until mid-2007 at which point it hit marginal GORs. Since then, the well has received less and less ontime as it shows decreasing recharge. No wellwork has been performed on E-15C. This well was drilled into a clean sand as a horizontal Zone 1A producer. As a result, there are no vertical barriers to try and shut off the gas and move production up towards the heel of the well. A decision was made to not try a CIBP and pert up toward the heel as it was deemed a low chance of success. Instead, it was thought that E-15D could possibly be drilled as a `plop and drop' and be completed with slotted liner. However, it was decided against as it was thought that it would draw in gas from the parent well As part of pre rig screening, an MIT-IA passed on 8/13/09 to 3000 psi and an MIT-OA passed to 2000 psi. A PPPOT-T passed to 5000 psi on 8/05/09. A caliper run on 8/12/09 found the 4.5" tubing and liner to be in good to fair condition with a max recorded wall penetration of 30%. REASON FOR SIDETRACK: Under current operating conditions this well has very little remaining value. There will be no wellwork performed on this well as it has been deemed a low chance of success. The latest well test came in at 500 bopd and 82k GOR. Currently this well has been deemed a LTSI well and will not receive much, if any, on time in the future. Pre-Rig Work (February 1, 2010) 1. O MIT-IA, MIT- OA -Done August 13 09- Passed, may need another one before rig moves to this well. 2. S Drift for Baker 4-1/2" Monobore Whipstock (3.625" X 12') to 10,450'MD 3.

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. When providing notice for a representative of the Commission to witness any required test, contact the Commission's petroleum field inspector at (907) 659-3607 (paler).

Lasley, Drilling Engineer Date: April 27, 2006 Re: E-15C Sidetrack Permit to Drill C by Well E-15B is a 1999 sidetrack that was completed in Zone 1A. In 2003 the well failed aMIT-OA and is currently on a surface waiver. Due to the surface casing waiver and high GOR, this well became a candidate for a rotary sidetrack. The surface casing communication problem will be rectified during the sidetrack operations by cutting and pulling the 9-5/8' casing, re-running and cementing in place. A 7" tieback will also be run to surface. The well, E-15C, will be kicked off in the Kingak formation and an 8-1/2" hole will be drilled to the intermediate 7" casing point at the top of the Sag River. A 6-1/8" 2,900' Zone 1A horizontal will be drilled to the Northwest. A 4-1/2" solid liner will be run, cemented and perforated throughout the production interval. The E-15C sidetrack is currently scheduled for Nabors 7ES, planned for 05/18/06, after completing the C- 22A sidetrack.

Wellplan can be extended if less than 800 of net pay is drilled. Fault Prognosis The proposed E-i5C well lies in a moderate risk province of the field for lost circulation at faults as documented by the WURD team. The risk of loss circulation events for this well is average. Nine loss circulation events were encountered in the Kingak and Ivishak in 8 of the surrounding 21 wells (38%) as detailed below. The planned well is expected to cross up to 4 faults. The first of. these, in Kingak, was penetrated in E-15A and was the likely cause of a 31 bbl loss circulation event while casing the 7" intermediate string. The second fault, expected in Zone 2, may not be seen as it will be crossed near its upper limit. The third and fourth faults are expected to be crossed in the horizontal in Zone 1 where the stratigraphy should minimize their potential for lost circulation. A fault located about 180 feet to the southwest of the planned well near the landing point and a fault tip-out zone 190 feet to the northeast both constrict the polygon at landing. An additional fault converges to within 140 feet southwest of the planned well near TD and the polygon is a hardline in this direction. The polygon allows for up to 200 feet of extension beyond the planned TD, if necessary. Loss Circulation Events Well Type Loss (bbl) MD SSTVD Formation Fault?
