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. (Submit a separate form for each additional interval to be separately produced, showing the data pertinent to such interval). ITEM 26: Method of Operation: Flowing, Gas Lift, Rod Pump, Hydraulic Pump, Submersible, Water Injection, Gas Injection, Shut-In, or Other (explain). ITEM 27: If no cores taken, indicate "None".

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. The permit is for a new wellbore segment of existing well PBU A-38, Permit No 193-032, API 50-029-22347. Production should continue to be reported as a function of the original API number stated above. 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.

Prep work will be limited to installing dummy gas lift valves and demonstrating mechanical integrity of wellbore. Sidetracking will occur off a mechanical whipstock, out of 3-3/16" liner at 11600' MD, in the Shublik interval. The target for the lateral is upper Zone 4. Approximately 1550' of 3" bi-center open hole is planned to access the target. The well will be completed / with an uncemented, pre-drilled liner. Production from the existing wellbores will be past the whipstock. Pre-rig Prep work. Planned for mid November, 2003 startup. 1. Install dummy GL V s. Drift tubing/liner with dummy whipstock to KOP. 2. MIT tubing/inner annulus to 3500 psi Nordic 2 CTD - Mill window, Drill and Complete sidetrack: Planned for December 07, 2003 startup. 1. RU Nordic 2, with 2" e-line coil and 7-1/16" BOP stack. 2. Install mechanical whipstock inside 3-3/16" liner for an 11600' MD KOP. 3. Mill 2.74" window from whipstock through the 3-3/16" liner / 4. Directionally drill -1550' to 13150' MD of 3" bi-center hole to access Zone 4 reserves. 5. Run 2-3/8" pre-drilled liner from TD up to 11500' md, approximately 3 joints above window. 6. RD Nordic 2. Install gas lift. Place well on production. / Mud Program: ~ · Milling: Y2# biozan water with 2# biozan sweeps. Drilling: Solids Free Flo-Pro (8.6 ~pg) Disposal: · All drilling and completion fluids and all other Class II wastes will go to Grind & Inject or Pad 3. · All Class I wastes will go to Pad 3 for disposal. Casing Program: · 1650' of 2-3/8" STL 4.6# L-80 pre-drilled liner from TD up into the 3-3/16" liner to 11,500' md. / Well Control: · BOP diagram is attached. / · Pipe rams, blind rams and the CT pack-off will be pressure tested to 400 psi and to 3500 psi. · The annular preventer will be tested to 400 psi and 2500 psi. Directional · See attached directional plan, 1550' planned horizontal. Max. planned hole angle is approx. -92 deg. · Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. Logging · An MWD Gamma Ray will be run over the entire open hole section. · MAD pass openhole Resistivity for determining water saturations. Hazards · The most recent H2S test on A-38Ll was 30 ppm. Prudhoe A Pad is a designated H2S pad. ./ · One mapped fault will be crossed. Lost circulation risk is considered low based on offsets. Reservoir Pressure · Pore pressure is estimated to be 3477 psi at 8800'TVDss (7.6 ppg emw). · Maximum surface pressure with gas (0.1 psi/ft) to surface is 2600 psi ./ TREE = 4-1/16" 5M CIW WELLHEAD= FMC 110-3/4" CSG, 45.5#,J-55 BUTT, ID = 9.953" 3388' Minimum ID :: 2.38" @ 11628' 3-3/16" X 2-7/8" XO 1 TOP OF 5-1/2" LNR 4-1/2" TaG, 12.6#, 13CR, 0.0152 bpf, 10 = 3.958" 13-1/2" LNR, 8.81#, L-80, 0.0086bpf, 10=2.99" 11471' FISH - 1" DMY GLV W/ BK LATCH (12/04/94) 15-1/2" LNR, 17#, 13CR NSCC, 0.0232 bpf, 10 =4.892"1 13-3/16" LNR, 6.2#, L-80, 0.0076bpf, ID = 2.80" PERFORA TION SUMMARY REF LOG: SWS BHCS ON 05/15/93 ANGLE AT TOP PERF: 34 @ 11524' Note: Refer to Production DB for historical perf data SIZE SPF INTERV AL DATE 33/8 6 11524-11544 04/13/96 3 3/8 4 11636-11705 OS/24/93 DATE REV BY COMMENTS OS/24/93 ORIGINAL COMPLErION 05/07/02 JDMlKK CTD SIDETRACK OTES: WARNING- RADIO TRANSMITTER IN MONITORING SHACK MUST SETURNED OFF BEFOREANY WELL WORK INVOLVING EXPLOSIVES CAN BEGIN.
