The permit to drill does not exempt you from obtaining additional permits required by law from other governmental agencies, and does not authorize conductiug drilling operations until all other required permitting determinations are made. To aid us in scheduling field work, please notify this office 24 hours prior to commencing installation of the blowout prevention equipment so that a representative of the Commission may be present to witness testing of the equipment before the surface casing shoe is drilled. ~ere a dtverter system is required, please also notify this office 24 hours prior to commencing equipment installation so that the Commission may witness testing before drilling below the shoe of the conductor pipe.

The surface location is Platform C, Leg 4, 'Conductor 26. Drilling operations are expected to commence February 10, 1990, and continue for two and one-half months. In the unlikely event that H2S is encountered, we intend to comply with the 20 AAC 25.065 and follow the "Recommended Practices for Conducting Oil and Gas Production Operations Involving Hydrogen Sulfide." Please note that the closest producer is C21-23, which is 750' from the proposed well at the top of the producing interval. This well, C12-23 is the third producer in the governmental quarter section, for which we request a variance from Conservation Order #44, Rule I (Spacing Pattern) under provisions contained in Conservation Order #44, Rule 6 (Administrative Approval). The current well plan calls for a TVD of 10,040', but SWEPI would like to maintain the flexibility to drill to a maximum prognosed TVD of 10,500'. If you have any questions concerning this application, please call Ms. Susan Brown-Maunder at (907) 263-9613.

MISCELLANEOUS C12-23 The maximum pressure gradient is expected to be .571 psi/ft. Maximum BHP is expected to be .571 x 10,040 : 5,733 psi. The shallowest depth at which abnormal waterflood pressures could be encountered is below the protective shoe. Maximum surface pressure is expected to be 2118 psi, assuming a full column of .360 psi/ft oil. The well will be drilled in compliance with the Alaska Oil & Gas Conservation Commission's regulations issued April 2, 1986. The proposed well path is in the vicinity of the following active producers and injectors: C42-23, C24-23RD, C31-26, C34-23 and C24A-23. In order to prevent possible intersections with these wells, collision cones of uncertainty have been calculated for each well based on the survey instruments used to survey each. The proposed wellpath does not intersect any of these collision cones. Should the actual wellpath intersect any of these collision cones, the affected well(s) will be shut in and bled down. Single shot gyro surveys will be taken while drilling the surface hole and MWD surveys will be used while drilling intermediate hole. As noted in the drawing of the diverter, both 10" mechanical valves will be kept in an open position until the preventer is closed. The mechanical valves will be wired full open and tagged with instructions concerning proper Procedures for closing a valve in the event the preventer is closed.

All flanges _shall be APl 6B or 6eX and ring gaskets sh.all be APl steel RX or BX. Do not re-use BX rings. Always use new rings below lower most preventer when flanges are parted. 3. Drilling spools shall be forged or forged and v~tded. Pipe spools not acceptable. 4. BOP stack shall be braced to subbase or suitable support by turnbuckled lines or rods. (No rigid connections.) .. 5. All gate valves shall be equipped with handwheeis. Rams should have manually operated screw locking exlensmns (extended beyond subbase) ready for use. 6. For land rigs the master control stalion and operaling unil shall be Iocaled at ground level e minimum of 50' from the well. The remotestat~on is to be located near the driiler's position. Inoperative condition of the remote unit is not lo interfere w~th operation of the master control unit. For platform and barge rigs she rTtaster control station and operating unit may be on the rig floor w~th the remote station located so that is protected from the well area end accessible from a logical evacuation route. Hydraulic lines may be high pressure hose provided they meet the require- ments Jn Section 4.3:2 in the Shell Well Control Manual. Housing and heating should be provided for accumulator, blowout preventers, choke manifold where conditions warrant. Contractor shal..___JI make no connection to casing head side outlets except by orders of Shell. One spare set pt ram blocks for the drill pipe in use shall be kept on rigs. 10. Any m~sai~gnment of rig should be corrected to avoid undue wear of casing. . 2. 3. 4. 5. 6. ' . 8. 9. 10. SHELL WESTERN E&P INC.
