Install 20" diverter. The Drilling fluid program will consist of an 9.5-10.0 ppg spud mud in the 17- 1/2" hole, a 9.5-10.4 ppg water base mud in the 12-1/4" hole and a 9.4 ppg water base mud in the 8-1/2" hole. Drill 17-1/2" hole to 2976' MD 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 4390 psi at 8800' TVDss based on original reservoir pressure. Maximum possible surface pressure is 3330 psi based on a gas column to surface from 8600' TVDss and an oil column to 8800' TVDss. Directional drill 12-1/4" hole to the 9-5/8" casing point above the Sadlerochit Sandstone. Run 9-5/8" 47// NT80-S NSCC casing to within 10' 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 5-1/2" liner from TD to 250' inside 9-5/8" casing shoe and cement using Class G cement. Clean out to 5-1/2" float equipment. Test casing and lap to 3000 psi. Change over to NaCL completion fluid. 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 10ft below base of permafrost. Install and test Xmas tree. Displace tubing to diesel. Set and test packer. The well will be perforated with rig on location. Fluids incidental to the drilling of a well will be pumped down the 9-5/8" x 13- 3/8" annulus of the well.
