Box 196612 Anchorage, Alaska 99519-6612 (907) 561-5111 Date: Oct. 15, 1995 To: Attention' Alaska Oil & Gas Conservation Commission 3001 Porcupine Drive Anchorage, Alaska 99501 Blair Wondzell Senior Petroleum Engineer A Permit to Drill application was filed on October 24, 1995 for a coiled tubing sidetrack of well S-28. The attached Form 10-403 is being submitted to complete the application by addressing the cement squeezing of existing perforations in S- 28. Well S-28 is a high TGOR producer that has been shut-in since 9/93. Existing Ivishak perforations will be squeezed in preparation for sidetracking with coiled tubing. The intent is to isolate the original S-28 perforations and produce only from the planned sidetrack, S-28A. Coiled tubing will be used to lay 15 bbls of cement from PBTD to approximately 100 ft above the top perforation at 9754' MD. Squeeze pressure will be applied and excess cement will be dressed off to approximately 9700' MD. This top of cement is required to accommodate a whipstock that will then be set at 9682' MD for the purpose of drilling the sidetrack, S-28A.

The drilling fluid program will consist of an 8.5 - 9.5 ppg spud mud in the 17- 1/2" hole, a 9.0 - 9.7 ppg water base mud in the 12-1/4" hole and a 9.0 ppg water base mud in the 8-1/2" hole. Drill 17-1/2" hole to 2500' TVD(BKB) and cement 13-3/8" L-80 Buttress casing to surface. Install blowout prevention equipment consisting of 5000 psi W.P. pipe rams, blind rams, and annular preventer. Maximum possible bottomhole pressure is 3710 psi at 8800' TVD(SS) based on original reservoir pressure. Maximum possible surface pressure is 3330 psi based on a gas column to surface from 8600' TVD(SS) and an oil column to 8800' TVD(SS). Directional drill 12-1/4" hole to the 9-5/8" casing point above the Sag River Sandstone. Run 9-5/8" 47# L-80 NSCC casing to within 5' of 12-1/4" TD and cement with Class G cement around the 9-5/8" shoe. The annulus will be freeze protected by dry crude. Directional drill 8-1/2" hole to TD. Run 7" liner from TD to 250' inside 9-5/8" casing shoe and cement using Class G cement. Clean out to 7" float equiPment. Change over to NaC1 completion fluid. Test casing and lap to 3000 psi. Run 9-5/8" production packer on tubing. Set packer 50' above top of liner. A subsurface safety valve with dual control lines will be placed 100' below base of permafrost. Install and test Xmas tree with diesel. Displace tubing to diesel. Set and test packer.
