The following summarizes the procedure required to prepare Y-34 for sidetracking and is submitted as an attachment to Form 10-403. A schematic diagram of the proposed sidetrack completion is attached. 1. A tubing integrity test will be performed. 2. Tubing and liner will be drifted with a 3.625" OD drift. 3. A mechanical whipstock will be set in the 5 1/2" liner at approx. 9475', or 49 ft below the top perforation. 4. Service coil will be used to downsqueeze approx. 25 bbls cement past the whipstock to abandon existing perfs. A squeeze pressure of 1500 psi will be achieved and witnessed by AOGCC prior to washing out cement above the whipstock. 5. The window will be milled with either service coil or drilling coil. A flowline will be used for returns if the milling is done with a service coil. Form 10-401 will be obtained prior to milling.

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# L-80 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.
