Drilling permits for this well have "/ '"1 already been applied for, but since then production from Y-26 has dropped off considerably. // ,] The decision was made to P&A the existing perfs (VS. retaining the perfs) to avoid any losses // // to the open perfs during the sidetrack operation.

The Drilling fluid program will consist of an 8.5-9.5 ppg spud mud in the 13-1/2" hole, a 9-9.8 ppg water base mud in the 9-7/8" hole and a 8.9 ppg water base mud in the 6-3/4" hole. Drill 13-1/2" hole to 2700' MD and cement 10-3/4" 45# 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. Directionally drill 9-7/8" hole to the 7-5/8" casing point at the top of Sag River formation. Run 7-5/8" 29.7# NT-95HS NSCC casing to within 10' of 9-7/8" TD and cement with Class G cement around the 7-5/8" shoe. The annulus will be freeze protected by dry crude. Directional drill 6-3/4" hole to TD. Run 5-1/2" Chrome liner from TD to 250' inside 7-5/8" casing shoe and cement using Class G cement. Clean out to 5- 1/2" landing collar. Change over to NaCL completion fluid. Test casing and lap to 3000 psi. Run 7-5/8" production packer on chrome 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. Displace tubing to Diesel. Set and test packer. The well will be perforated after rig release. Fluids incidental to the drilling of a well will be pumped down the 7-5/8" x 10-3/4" annulus of the well.
