W. F. Simpson Manager, Regulatory Affairs ...... Alaska Division Shell Western E&P Inc. 601 West Fifth Avenue, Suite 800 Anchorage, Alaska 99501 Dear Mr. Simpson: The referenced application was received on December 28, 1990. The Middle Ground Shoal No. Cll-23 well is in the steeply dipping west flank part of the reservoir which requires closer than 80 acre spacing to adequately drain this part of the pool. The Alaska Oil and Gas Conservation Commission has reviewed the evidence available and hereby authorizes the drilling, completion and production of the referenced well pursuant to Rule 6 of Conservation Order #44. Sincerely, Russell A. Douglass Commissioner BY ORDER OF THE COMMISSION Shell Western E&P Inc.

Cll-23 Enclosed in triplicate is the Application for Permit to Drill the next well at Middle Ground Shoal, well no. Cll-23. The surface location is Platform C, Leg 4, Conductor 27. Conductor 27 was previously used for the C43-23 well, for which the permit to abandon the well was submitted December 18, 1990. Cll-23 is currently scheduled to spud on February 15, 199~ following well slot recovery operations. Drilling operations are expected to continue for approximately two and one-half months. In the unlikely event that H2S is encountered, we intend to comply with 20 AAC 25.065 and follow the "Recommended Practices for Conducting Oil and Gas Production Operations Involving Hydrogen Sulfide." Please note that Cll-23 is the fourth producer in the governmental quarter section. SWEPI requests a variance by way of Administrative Approval (Rule 6), from Rule 1 of Conservation Order #44. The current well plan calls for a TVD of 11,236', but SWEPI would like to maintain the flexibility to drill to a maximum prognosed TVD of 12,000'.

Maximum BHP is expected to be .571 x 11,236 = 6,416 psi. The shallowest depth at which abnormal waterflood pressures could be encountered is below the protective shoe. Maximum surface pressure is expected to be 2371 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 will pass in the vicinity of several active producers and injectors. In order to prevent possible intersections with these wells, collision cones of uncertainty will be calculated for each well based on the survey instruments used to survey each. The proposed wellpath will 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.
