The pennit to redrill does not exempt you from obtaining additional pennits or approvals required by law from other governmental agencies, and does not authorize conducting drilling operations until all other required pennits and approvals have been issued. In addition, the Commission reserves the right to withdraw the permit in the event it was erroneously issued. The pennit is for a new wellbore segment of existing well PBU K-16A, Pennit No 198-180, API 029-22430-01. Production should continue to be reported as a function of the original API number stated above. Operations must be conducted in accordance with AS 31.05 and Title 20, Chapter 25 of the Alaska Administrative Code unless the Commission specifically authorizes a variance. Failure to comply with an applicable provision of AS 31.05, Title 20, Chapter 25 of the Alaska Administrative Code, or a Commission order, or the tenns and conditions of this pennit may result in the revocation or suspension of the permit. Please provide at least twenty-four (24) hours notice for a representative of the Commission to witness any required test. Contact the Commission's North Slope petroleum field inspector at 659-3607 (pager).

Using a mechanical whipstock a window will first be cut in 4%" liner at 10,080'. The first of two Ivishak Zone 1A laterals will then be drilled, 1460' to the east and completed with 2*" slotted liner. The top of this first liner will be placed 100' below the window to facilitate the an OH sidetrack for the second lateral. The second lateral will then be drilled 1325' to the west and again completed with 2*" slotted liner. The top of this liner will be placed just below the window to allow the retrieval of the mechanical whipstock and the unplugging of the parent well perfs. K-16AL 1 L2 will ultimately be a tri-Iateral producer. Phase 1: Prep work. Planned to start September 15, 2002. 1. With seNice-coil, run & set either a packer or an inflatable plug at in the 4%" liner at - 10, 120'md to / minimize fluid loss to the parent well perfs. 2. With service coil run & set a retrievable whipstock in the 4%" liner at 10,080' to facilitate the milling of a window in the liner Phase 2: Mill window, Drill and Complete sidetrack: Planned for October 14, 2002. 1. Drilling coil will be used to mill the window then drill and complete the 2 x directional holes as per attached plans. Maximum hole angle will be 95° in sidetrack L 1. Mud Program: . Phase 1: 2% KCI brine . Phase 2: Mill: viscosified 2% KCI wI 2ppb biozan system. Drilling: 8.7 ppg Flo-Pro bio-polymer system 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: The production liners will be slotted, 2*", L-80 grade ST-L pipe. For lateral L 1 to the east it will be run from TO, (11,540') back to -100ft below the window at 10,080'. For lateral L2 to the west it will be run from TO, (11,500') back to just below the window. Liner top placement will facilitate the removal of the whipstock & plug or packer. 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 2500 psi. Directional . See attached directional plans. Max. planned hole angle is 95° in lateral L 1. . Magnetic and inclination sUNeys will be taken every 30 ft. No gyro will be run. Logging . MWD & Gamma Ray will be run in the open hole section. A Memory GR/CCL log will be run with the liner setting tool to verify placement of the liner tops upon release. Hazards . The concentration of HzS in K-pad well process streams is <10ppm. . No faulting of seismic resolution will be encountered by the wellpath. The lost circulation risk is low. Reservoir Pressure Res. pressure is estimated to be 3250 psi a1-8800'tvdss (7.1 ppg emw).
