Enclosed is the approved application for permit to redrill the above referenced well. 'The permit to redrill 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) must be given to allow a representative of the Commission to witness a test of BOPE installed prior to drilling new hole.

The sidetrack, J-24a, will exit the 7" liner in the Sag R. interval and target the Sag R. Existing perfs will be squeezed by pumping approx. 20 bbls cement past the whipstock. The J-24a completion will involve cementing 3 3/16" x 2 7/8" solid liner across the initial open hole while placing a 2 7/8" slotted liner across the Sag R. completion interval. Phase 1: Drift, set whipstock on E-Line, mill window. Planned for Dec. 27-29, 2000. · Wellhead seals have been tested. · Tubing integrity has been confirmed. · All GLM's have been dummied off. · The IA will be loaded and pressure tested. · A dummy whipstock drift has been run on slickline. · A Kinley caliper has been run across the tubing and liner. · CTE-Line will set the whipstock at approx. 10,860' MD (8543'ss). Phase 2: Drill and Complete sidetrack: Planned for Jan. 5, 2001. RECEIVED DEC 19 2000 Alaska 0il & Gas C0'ns. Commission Anchorage Drilling coil will be used to drill and complete the directional hole as per attached plan. The sidetrack will be completed with a slotted/solid-cemented liner. Top of 3 3/16" liner to be approx. 10,560' MD (8320' ss). Mud Program: · Phase 1: Seawater · Phase 2: FIo-Pro (8.6 - 8.7 ppg) Disposal: · All drilling and completion fluids and all other Class II wastes will go to Grind & Inject. · All Class I wastes will go to Pad 3 for disposal. Casing Program: · 2 7/8" slotted/solid liner will be run from TD to approx. 10,900' MD (8573'ss). 2 7/8" slotted liner will be used within the Sag R. completion interval and solid liner (3 3/16" x 2 7/8") will be used from the top of slotted liner to the top of the liner at 10,560' (8320'ss). The crossover between the 2 7/8" solid/cemented and the 2 7/8" slotted liner will be at approx. 11,700' MD (8587'ss). The 3 3/16" x 2 7/8" solid liner will be cemented with approx. 13 bbls cement. Well Control: · BOP diagram is attached. · Pipe rams, blind rams and the CT pack off will be pressure tested to 400 psi and to 3500 psi. · The annular preventer will be tested to 400 psi and 2000 psi. Directional · See attached directional plan. BHL (State Plane): 646,800; 5,975,107. Max. hole angle is 96 deg. · Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run.
