ITEM 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 elevation in feet above mean low low water. 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: True vertical thickness. ITEM 22: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool. ITEM 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.

The pennit is for a new wellbore segment of existing well PBU S-213A, Pennit No. 204-213, API 50-029-22993-01. Production should continue to be reported as a function ofthe original API number stated above. This pennit to redrill does not exempt you from obtaining additional pennits or approvals required by law from other governmental agencies, and does not authorize conducting drilling operations until all other required pennits and approvals have been issued. In addition, the Commission reserves the right to withdraw the pennit 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 tenns and conditions of this pennit may result in the revocation or suspension of the pennit. Please provide at least twenty-four (24) hours notice for a representative of the Commission t 'tness any required test. Contact the Commission's petroleum field inspector at (907) 659- ager).

Hydrates and Shallow gas: A. Gas hydrates are present below S-pad, but have not been a significant issue thus far during S-Pad drilling. If hydrates are encountered follow the recommended practice and apply good drilling operational practices. III. Lost Circulation/Breathing: A. Lost circulation is possible within the Schrader interval due to the reduced pore pressure. A LCM decision tree has been developed to give direction in the event of losses. B. We do not expect breathing on this well as we are above the more prevalent breathing shale's i.e. Seabee. IV. Kick Tolerance/lntegrity Testing: A. The 9-%" casing has been cemented to surface. B. The 7-%" flush joint casing will be cemented with 15.8 Ib/gal cement to 500' MD above the Ma sand. C. Integrity Testing: NOTE: If the LOT I FIT is less then the minimum notify the ODE immediately Surface I 8-3,4" 52.2 9.2 8.9 12.2 (LOT) Intermediate I 6-3,4" Infinite 9.2 8.9 10.5 (FIT) NOTE: FIT's will only be done on the first horizontal lateral due to pressure connectivity between subsequent laterals. NOTE: All LOT I FIT will be taken with a minimum of 2o-ft and a maximum of So-ft of new hole drilled outside of the previous casing string V. Stuck Pipe A. There could be slight differential sticking across the reservoir while running the slotted liners. Keep the liners moving as much as possible and run one centralizer per joint to help with standoff. VI. Hydrogen Sulfide A. S-Pad is not designated as an H2S site, however Standard Operating Procedures for H2S precautions should be followed at all times. In Nov. 2003 85 ppm of H2S was measured at one S-Pad well (S-05A), however all other wells tested below 20 ppm in 2004 and since the reading, S-05A has been shut in. VII. Faults There is one planned fault crossing and two possible fault crossings while drilling the well. It is also possible to encounter sub-seismic faults along the proposed well path. In the production hole sections, if a fault throws us out of section steer up as fast as possible to determine where we are within the section. This will make it easy to lows ide OH sidetrack to get back on course.

Rig up Schlumberger slickline, and drift tubing down to the jet pump fish with drift appropriate for 3.5" chemical/jet cutter. Last well operation was CTU fishing attempts to retrieve the jet pump. Last tag was at 5,314' CTU MD. a. NOTE: If use the chemical cutter it will be required to have the tubing and annulus hydrostatic pressures equalized prior to cutting the tubing. It may be desirable to punch holes in the tubing just below the proposed chemical cut depth in order to allow for pressure equalization. Optional string shot per SOP. 2. RIH w/ chemical/jet cutter. Cut the 3-%" L-80 tubing at approximately 5,250' MD. Chemical cutter is at the discretion of the Wells Group Representative. This cut will not be fished, however a complete cut is critical to successful decompletion. a. NOTE: If chemical cutter is used, then the well should be displaced to seawater prior to making the cut. It is against SOP to use a chemical cutter in diesel. 3. RU and circulate out the diesel through the tubing cut. Once the tubing ànd annulus are displaced, bullhead sufficient seawater below the jet pump to fill the volume (-20 bbls) to the perfs. Observe 1.5 bpm, 2500 psi max. Previous injectivity tests that were done showed a rate through the jet pump of approximately 1.2 bbls/min @ 2,000 psi surface pressure. Freeze protect down to 2,000' TVD with diesel. a. NOTE: This will leave the well -60 psi under-balanced with the formation. A static BHP was taken on 9/18/04 which gave a reservoir pressure of 2,110 psi @ 5,000' TVDss (8.12 ppg EMW). These pressures assume a diesel gradient of 0.354 psi/ft down to 2,000' TVDss and a seawater gradient of 0.447psi/ft down to 5,000' TVDss. b. NOTE: The well should not be left with methanol as a freeze protect fluid, diesel only. 4. Test all packoffs and tubing hanger seals to 5,000 psi for 30 minutes. MITOA and function test alllockdown screws, repair or replace as needed. a. Verify tubing and annuls pressures and give to rig during the handover. Set a BPV in the tubing hanger and a VR plug in the 7x4-W IA valve. Secure well. 5. Remove the well house and flowlines. If necessary, level the pad. Please provide total well preparation cost on the handover form. Drillinq Riq Decompletion Operations: 1. MIRU Doyon 16. Circulate out diesel with seawater. Verify the well is dead. 2. Set TWC.
