The following summarizes the procedure required to prep 4-41 for drilling and is submitted as an attachment to Form 10-403. A schematic diagram of this proposed completion is attached. ]. The gas lift mandrels will be dummied off and a Mechanical Integrity Test is planned. 2. The well will be drifted to 2.8" id and a memory GR/CCL will be run with slickline. 3. Service coil will pump approx. 12bbls of cement to P&A the existing perforations. 4. The window will be milled off of a cement ramp with service coil. The KOP will be at approximately 9,676'md. 5. A sidetrack of approx. 1769 ft into lower Zone 1 will be drilled with CT. 6. The sidetrack will be completed with a cemented 2 3/8" liner that will overlap the existing 3 Y2" tubing to ,-,9480'md (TOL). The estimated Top of cement is planned for 188' above the window to the liner top. The coil tubing operations are expected to commence November 25. Drilling coil is expected to begin the sidetrack drilling on December 2, 2000. Thomas M.

P/U 9-7/8" BHA and RIH. Test casing to 3500 psi for 30 minutes. Drill 10' of new hole and perform leak of test. . Drill 9-7/8" intermediate hole to kick of point at 3600'MD/TVD. Build angle at 2.5 deg/100'md until 36.01" of inclination is achieved at 6313' MD/6296'TVD. 5. Drill 9-7/8" intermediate hole to 7-5/8" casing point at 8560'TVD/9506MD. (10' above Sadlerochit top ) 6. RIH with 7-5/8" casing and cement the same. , Pick up 6-3/4" BHA and RIH , test casing to 3500 psi. for 30 minutes. Drill production hole to 10052'MD/9001'TVD, condition hole to run open hole logs. 8. Run open hole logs as programmed. 9. Set 5-1/2" 13 CR liner and cement the same. 10. Clean out the liner and test liner to 3000 psi for 30 minutes. Displace well to 8.6 ppg filtered seawater and re:test casing to 3000 psi for 30 minutes. 11. Run cased hole logs. 12. Rig up Wireline and perforate. 13. Run 4-1/2" 13 CR tubing and packer assembly with SSSV. Test tubing and casing to 3000 psi. Freeze protect with diesel. 14. N/U tree and test to 5000 psi. Release Drilling Rig. PBU DS 4-4,~ OPERATIONS SUMMARY C0NT'D Anticipated BHP: Maximum Anticipated Surface Pressure: Planned Completion Fluid: 3600 psi @ 8800'SS 2800 psi 8.6 filtered seawater Note: a. Excess non-hazardous fluids developed from the well operations and as necessary to con, trol the reserve pit fluid level will be pumped down the 7-5/8" x 10-3/4" annulus. The annulus will be left with a non-freezing fluid during any extended period. The annulus will be sealed with 300 sxs of cement followed by Arctic Pak. b. Minimum distances of wells within 200 ft. of the proposed well are: "DS 4-07: 100' @ 4200' MD/TVD "DS 4-08: 50' @ 2400' MD/TVD ~ DS 4-09: 126' @ 3600' MD/TVD c. The drilling fluid program and surface system will conform to the regulations set forth in 20AAC25.003. d. Maximum surface pressure is based on BHP and a full column of gas to TD (0.10 psi/ft ). e. Based on previous logs on DS#4, no potential productive zones are anticipated above 3500' TVD. f. No potential hazardous levels of H2S are anticipated in this well. · Co, AnCt~ora#e~' m~ni$$1en DS 4-41 MUD PROGRAM Depth Density ViS YP INT 10MIN FL OIL SOLIDS IVIJD (TVD) (PPG) GELS GELS cc/3omin (%) (%) TYPE SPUD 8.8 300 70 30+ 50+ 25 0 2 TO TO TO TO TO 10-3/4" 9.2 100 40 6 csg. pt.
