The permit to drill does not exempt you from obtaining additional permits required by law from other governmental agencies, and does not authorize conducting drilling operations until all other required permitting determinations are made. Blowout prevention equipment (BOPE) must be tested in aCcordance with 20 AAC 25.035. Sufficient notice (approximately 24 hours) of the BOPE test performed before drilling below the surface casing shoe must be given so that a representative of the Commission may witness the test. Notice may be given by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607.

Diverter system will be installed. The Drilling fluid program will consist of an 8.5 - 9.5 ppg spud mud in the 13- 1/2" hole, a 9.0 - 9.7 ppg water base mud in the 9-7/8" hole and an 8.7 ppg water based mud in the 6-3/4" hole. Drill 13-1/2" hole to 3050' MDBKB. Run and cement 10-3/4", 45.5#, 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. A formation leak'off test will be Performed 10' below the 10-3/4" shoe. '. Directionally drill 9-7/8" hole to the 7-5/8" casing point above the top of Sag River Sandstone. Run a 7-5/8", 29.7 # NSCC casing string to within 10' of 9- 7/8" TD and cement with Class G cement around the 7-5/8" shoe (cement volume to cover Ugnu formation by 500'). The annulus will be freeze protected by dead crude oil. Directionally drill the 6-3/4" hole to TD. Run 5-1/2" liner from TD to 250' inside 7-5/8" casing shoe and cement using Class G cement. Clean out to 5-1/2" float equipment. Change over to NaCI completion fluid. Test casing and lap to 3500 psi. Run 7-5/8" 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. Freeze protect the tubing and tubing annulus by evacuating the liquid utilizing gas lift throught the first gas lift valve at 3000' TVDBKB. Freeze protect the 10-3/4"-7-5/8" by dry crude to 2300' TVDBKB. Set and test packer. The well will be perforated after the rig has been released. Fluids incidental to the drilling of a well will be hauled to a central injection facility at CC2. Tubing Size: 4-1/2", 12.6 # NT13CR-80, Fox tubing with 6 GLM's. RECEIVED JUhi 1 5 1997.
