Drilling Engineer: Mel Rixse, 5645620 INSTRUCTIONS GeNeRA~: 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. 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. 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). IreM 20: Report true vertical thickness of permafrost in Box 20. Provide MD and TVD for the top and base of permafrost in Box 28. 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).

Isolation of the existing 15-15B perforations using a CIBP is proposed in preparing the well for a new coiled tubing drilling lateral. The new lateral will be targeting an undrained area to the north of the existing B lateral leg. The new lateral will be a cemented and perforated solid liner. HISTORY: 15-156 is a CTD sidetrack completed in January 2003. The sidetrack targeted an area not far from well 07-16, which had previously been part of a pilot program for water injection in the gravity drainage area. During drilling, 15-15B crossed a fault and encountered notably higher water saturation on the downthrown side. In fact, initial production from 15-156 was 95% water (1520 bpd gross fluid rate). The well now makes ~ 30% water (340 bpd gross fluid), so not only has the water cut decreased, but the total water rate has also dropped. Upon completion, 15-15B was expected to spend some time de-watering the reservoir, after which the oil rates would increase. 15-15B has never produced very much gas -In fact, the well required raw gas lift for the first four months of its life, current gas rates are averaging about 13.5 MMSCFD with an uptime of 36% in the last 12 months. To offset the well's low production rate, 50' of perforations were added uphole in May 2004, but these had no impact on production. A FCO and diesel/xylene pert wash treatment was proposed in July 2007 to help improve productivity. However, coil could not get past 11255' MD (top perfs are located at 12305' MD) and so the 50:50 diesel/xylene was bullheaded without performing the FCO or pert wash /jetting procedure. The well received negligible benefit from the bullheading treatment. Coil came back to perform a mill and fill cleanout on 8/5/07 and successfully milled through the obstruction at 11255' MD to TD. They encountered some scale-like material while conducting this operation. The post milling rates showed the well producing at improved rates while on PBGL. Therefore, it was decided to pump an HCL stim and add a multilateral to the existing leg. The CTD multi-lateral attempt in December 2007 could not be completed after the CTU (pre riq pJgp,~,. failed to set the whipstock at the desired Zone1 kick-off point of 11.345' and -due to dop leos. The coil / whipstock BHA was getting hung up at 11,247' md. The job was aborted and the 4.5" KB LTP was set at 10,994' md. Prior to that, the well had an HCL stimulation treatment pumped in early December 2007 and the post acid rates showed the performance to have improved slightly with the well managing to stay fulltime for about 5 months. However, the most recent POP attempt saw the well hitting MGOR within 2 weeks of being brought online even after having been SI for 4 months. 15-156 had a passing MITIA to 3000 psi and a failing MITOA to 2000 psi on 10-30-2008. The MITT passed to 3000 psi in September 2008 prior to a tree change out. The June 2007 calliper shows both the 5-1/2" and 4-1/2" tubing to be in good shape with a maximum wall penetration = 34%. REASON FOR SIDETRACK: 15-156 is a cycle well in the LP header with low fluid rates and a decreasing ontime. The well cycles when the oil rate drops after initial flush production following ashut-in period, and the well very quickly reaches MGOR. The CST will enable this 4-1/2"cr x 5-1/2"cr wellbore to be more effectively utilized. Pre-Rig Work: • 1. O PT Master & Swab valve to 4500 psi. Drawdown test MV and SV to 0 psi 2.

This permit to redrill does not exempt you from obtaining additional permits or approvals 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. Please provide at least twenty-four (24) hours notice for a representative of the Commission to witness any required test. Contact the Commission's North Slope petroleum field inspector at 659-3607 (pager). Sincerely, ~#~ Michael L.
