PREPARED FOR: ARCO Alaska, Inc. PREPARED BY: W.A. Shepherd Sperry-Sun Drilling Services Logging Systems Anchorage, Alaska The following information was derived from in house evaluations of well cuttings caught at the Nabors 2ES rig site during the drilling of well 5-10A. The lithological evaluation was performed for the Horizontal / Slimhole section. The Engineer and Sample Catcher on location performed their duties on a twelve hour tour basis. The method of lag calculations used for depth tagging the samples were derived from borehole and surface equipment geometry. This calculation was checked by use of u-circulated calcium carbide pills. Sample evaluations were performed by W.A. Shepherd, Sperry-Sun Drilling Services' Geologist/Logging Engineer, inhouse at our Anchorage lab. W.A. was able to give an interpretive analysis of lithology by utilizing FE/MWD data recorded from the wellsite.

The permit to redrill does not exempt you from obtaining additional permits required by law from other governmental agencies, and does not authorize conducting drilling operations until all other required permitting determinations are made. Blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 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 new hole. Notice may be given by contacting the Commission petroleum field inspector.on the North Slope pager at 659-3607.

The well has a 1987 cement squeeze which has repeatedly broken down, and no feasible fix has been found. A replacement wellbore will allow the reserves originally targeted by well 5-10 to be produced. Drilling this well horizontally will drain the reserves more effectively. The zone 1 oil column is expected to have 60' NLOC. Post-sidetrack rates are estimated at 1000 BOPD, 1000 SCF/STB and 10% WC. Mud Program: Special design considerations After dressing off the kickoff plug we will displace to Flopro system (Xanvis) and drill to 7" shoe depth with @ 10.00 ppg to 10.20 ppg. 6" hole will be drilled with the same system with @ 9.2 ppg to 9.4 ppg.

Lay cement plug across perforations to at least 100' above top pedoration. Cut the 4-1/2" tubing near 8015' MD. Freeze protect and set a BPV. Test intermediate casing pack-off to 5000 psi. Move in drilling rig. Test 9-5/8" intermediate casing pack-off if not done during pre-rig work. Puli BPV. Circulate diesel freeze protection cap from well and recover for future use. Install a BPV and test tree plug. Remove the production tree. Install BOP's and test to 5000 psi. Remove the test plug and BPV. Puli and lay down the 4-1/2" tubing. Spot a 18 ppg pill on bottom and cut a 50' section in the 9-5/8" casing starting from about 7700'MD. Spot a balanced cement kick-off plug (180 cubic feet minimum) through open- ended drilipipe from 100' below the base of the section to 200' above the top of the section. Run in with an 8-1/2" Steerable drilling assembly and dress the cement to 5' below the section top. Kickoff and'directionally d-rill to the target with 90° hole angle at 8940'ss as per the attached directional plan. Obtain Direction ! GR / Resistivity / Neutron / Density formation evaluation logs while drilling starting from the top of the Sag River Fm. Run a 7" 29 # 13cr liner assembly to bottom in the 8-1/2" hole and up to 100" above the top of sand followed with 7" 29# L-80. Space the liner hanger (L-80) and top isolation packer (L-80) about 150' up inside the 9-5/8" casing. Cement the liner in place with the total cement volume based upon 60 % open- hole enlargement plus the 80' shoe volume, 150' lap volume and 150' excess on top of the liner with drillpipe in the hole. Re-test BOP's as needed. Run in with 6" steerable drilling assembly with direction / GR MWD on 4-1/2" x 3- 1/2" drillpipe. Test casing to 3500 psi for 15 min. before drilling out float shoe and 10' of new hole. Displace well with non-damaging (Fig-Pro Xanvis polymer) drilling fluid. See MI Drilling Fluids recommended displacement procedure. Drill approximately 8101 of 6" hole to TD as per Geologist / Operations Engineer onsite. Make a conditioning trip with a 6" hole-opener for the open hole section with a 7" casing scraper spaced to clean the liner. Install a .4.-1/2" NT-80S slotted liner with 4-1/2" X 7" packer / hanger. Run in on drilipipe with a 2-1/16" wash string inside the slotted liner. Space packer / hanger to be set within about 150' of the 7" liner shoe. Position packer above the 7" liner shoe and circulate. Set packer and test. Release from the packer / hanger and displace the drilling fluid with filtered seawater but no corrosion inhibitor. After circulating clean with seawater, spot a Xanvis mud breaker in the horizontal hole section. RECEIVED MAR 2 4 1994 Alaska Oil & Gas Con;.
