The sidetrack, 18..18b, will kick off from a window milled in Zone 1 of the Ivishak. The 18-18b target is Zone 1 A/1 B. The following describes work planned to prep for sidetracking and is submitted as an attachment to Form 1 0-403. A schematic diagram of the proposed sidetrack is attached for reference. 1. MIT has been successfully performed on the OA. (2/3/02) 2. Kinley Caliper has been run over the tubing. (2/19/02) 3. All GLM's have been dummied off and MIT-IA successful to 2500 psi. (4/3-4/02) 4. Service coil will kill the well with drilling fluid (8.6 ppg Flo-Pro) and set a mechanical whipstock at approx. 12,100' MD (8634ss). If the existing perfs at and above the whipstock depth do not ta~' drilling fluid under circulating conditions then the sidetrack will be drilled with these perfs open. . If the perfs do take fluid during the whipstock setting operation then service coil will squeeze approx. 25 ~ bbls 15.8 ppg cement to shut off these perfs. These exis, perfs will be covered in any event by the cemented liner planned for the sidetrack completion. 5. Window will be milled with drilling coil. Steps 4 will be performed between July 15 and Aug. 1, 2002. Drilling coil is scheduled to mill the window and drill the sidetrack on August 10, 2002.

March 11. 1995: I witnessed the weekly BOP test on Nabors rig # 2 ES which was drilling Arco well # OS 18-18 in the Prudhoe Bay Field. The test was started at 0900. A low/high test of 300/5000 psi was put on all BOPE with the exception of the annular preventer which was tested to 300/3000 psi. A recharge test was performed that showed the accumulator was in satisfactory shape. The choke manifold was tested with all valves operating properly and holding their pressure test of 300/5000 psi. The gas detection system was tested. All components functioned properly although the high alarm on the methane detectors did not activate until 60% LEL. This was set to 50% in my presence. I found the condition of the rig to be in very good shape. SUMMARY: I witnessed the weekly BOP test on Nabors rig # 2 ES drilling Arco well # OS 18-18. Test time 3 1/2 hours, no failures.

The permit to re-drill does not exempt you from obtaining additional permits required by law from other governmental agencies, and does not authorize conducting re-drilling operations until all other required permitting determinations are made. Blowout prevention equipment (BOPE) must be tested in accordance with 20 MC 25.035. Sufficient notice (approximately 24 hours) must be given to allow a representative of the Commission to witness a test of BOPE installed prior to drilling a new hole.

Objective: The scope of the AFG at this time is defined by the following general plan: Abandon the current slotted liner completion prior to arrival of the drilling rig. Remove that portion of the existing 3-1/211 completion above the production packer. Abandon the production packer and tubing tail assembly in place. Mill away a section of the 711 liner above the abandoned packer and tail assembly. Place cement below and across the previously milled section to serve as a combination IIkick-offll/abandonment plug. Drill a new 6" hole, exiting through the section and on to the proposed target, as defined in the attached directional plan (plan #6). Use a real-time MWD gamma ray log for geological correlation. Once the hole is inclined to horizontal and reaches the target, acquire drillpipe-conveyed, electric line formation evaluation logs for GaG identification. Exte30Q' to the proposed bottom-hole location (BHL). Use only truly non-damaging drilling fluids (FloPro®) in this interval. Gase and cement the hole with a 4-1/211 L-80 liner. Perforate the horizontal section with drillpipe conveyed 2-3/411 guns. Finally, complete the well with 3-1/211 L-80 tubing. Mud Program: Special design considerations After dressing off the kickoff plug we will displace to KCL system (Xanvis) and drill to TD with 9.0 ppg Flo-Pro mud.

Pre-rig work: P&A well and cut 3.5" tubing.Set and test BPV. 2. Move in drilling rig. Test 9-5/811 intermediate casing pack-off . 3. Pull BPV. Circulate diesel freeze protection cap from well and recover for future use. 4. Install a BPV and test tree plug. Remove the production tree. 5. Install BOP's and test to 250/5000 psi. Remove the test plug and BPV. 6. Pull and lay down the 3-1/211 tubing from the cut to surface. 7. P/U 7" section mill. RIH to ..... 200' below proposed 7'1 section. 8. Displace to milling fluid and spot a 18 ppg pill on bottom and cut a 50' section in the 7" casing starting from about 9730' MD. 9. Spot a balanced cement kick-off plug (150 cubic feet minimum) through open- ended drillpipe from 100' below the base of the section to 200' above the top of the section. 10. Run in with a 611 steerable drilling assembly ( incl'd MWD / GR ) and dress the cement to 5' below the section top. Prior to kickoff circulate hole clean so that it is free of cement. Kickoff and directionally drill to the target with 89.28° hole angle at 8650'ss as per the attached directional plan. Obtain GR / SP / DDL / SONIC / CNL formation evaluation logs via drill pipe conveyed method. Make cleanout run as needed and continue to drill 611 horizontal section to TD as per enclosed directional plan. ( NOTE: Due to geological uncertainties it is likely that we may have to plug back this well. Tatal estimated cost includes thia plug back contigency ) 11. Run a 4.511 12.6 # L-80 liner assembly to TD in the 611 hole. Space out liner top packer/hanger @ 150' inside of 7 casing window. 12. Cement the liner in place with the total cement volume based upon 40 0/0 open-hole enlargement plus the 40' shoe volume, 1501 lap volume and 150' excess on top of the liner with drillpipe in the hole. ( Note: if the caliper log is available use it and add 20% to caliper volume) 13. P/U 3.87511 bit / mill ( use drilex motor) and clean-out 4.511 liner to top of landing collar. 14. Displace well to SW. POOH. 15. P/U 2-3/411 guns and perforate 4.511 liner. (underbal. via drill pipe conveyed method) 15. Install a BPV and test plug. Remove BOPls. 16. Run 3.511 completion as per program. 17. Release rig. 18. Complete appropriate documentation and hand-over to Production. RE(EIVED FEB - 9 1995 Aiaska Oil & Gas Cons.
