Use same as reference for depth measurements given in other spaces on this form and in any attachments. Item 13: The API number reported to AOGCC must be 14 digits (ex: 50-029-20123-00-00). Item 20: True vertical thickness. Item 22: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool. Item 23: If this well is completed for separate production from more than one interval (multiple completion'), so state in item 1, and in item 23 show the producing intervals for only the interval reported in item 26. (Submit a separate form for each additional interval to be separately produced, showing the data pertinent to such interval).

The Application for Permit to Drill C22A--26LN is submitted under separate cover. The anticipated commencement date of this work is approximately October 10, 2004. The existing tubing and packer will be pulled and the well plugged with cement selover the interval from PBTD to 115' above the topmost existing perforation. After the cement plug integrity is tested with weight, the well wìll be sidetracked from the top of the plug to a new location in the reservoir.

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 May 10, 1990. The drilling of the Middle Ground Shoal No. C-22A-26 is in the steeply dipping West Flank part of the field which requires closer than 80 acre areal well spacing to adequately drain this part of the reservoir. The Alaska Oil and Gas Conservation Commission has studied, the evidence available and hereby authorizes the drilling, com- pletion, and production of the referenced well pursuant to Rule 6 of Conservation Order 44.

C22A-26 Enclosed in triplicate is the Application for Permit to Drill the next well at Middle Ground Shoal, well no. C22A-26. The surface location is Platform C, Leg 4, Conductor 30. The well is currently scheduled to spud on May 18, 1990. 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 C22-26, which is 1440' from the proposed well at the top of the producing interval. This well, C22A-26 is the third producer in the governmental quarter section, for which we request a variance from Conservation Order #44, Rule 1 (Spacing Pattern) under provisions contained in Conservation Order #44, Rule 6 (Administrative Approval). The current well plan calls for a TVD of 10,042', but SWEPI would like to maintain the flexibility to drill to a maximum prognosed TVD of 10,500'.

There may be several strings of casing;~ one inside the other, in a single well. Most oil wells are completed with two strings of cemented casing, the surface pipe and the production string. The surface pipe serves as conductor of the drilling fluid through loose, near-surface formations during deeper drilling, protects potable water supplies, anchors blowout preventers for deeper drilling, and supports at the surface deeper casing strings when hung. The production string serves as a conduit to the surface for produced fluids and confines each fluid- bearing zone to its native place. In many cases a third casing, called the intermediate or protective string is also cemented in place. This string sometimes accomplishes some of the purposes of surface strings but generally it is set for the purpose of protecting sections of formations which would prove troublesome if exposed during deeper drilling. See Bugbee, "An Introduction to Oil Well Cement Technol- ogy,'' 16 Oil and Gas Compact Bull 26 (June 1957). "Production casing is the series of steel pipe lengths, screwed or welded together and called the 'string,' through which the oil flows to the surface. Surface-casing is not the same as the production string. It usually is an outer casing or jacket of the string. One pur- pose of surface-casing is to prevent contamination of fresh water strata which have been penetrated and to seal off fluids from the hole. Another purpose is to prevent caving at the surface. Surface- casing is a tubular product lighter than the string. Sometimes, how- ever, the production string itself serves as the surface-casing. Surface- casing may go down a thousand feet or more." Harper Oil Co. v. United States, 425 F.2d 1335 at 1336, 36 O.&G.R. 190 at 192 (10th Cir. 1970). See also Ocrr£R CONDUCTOR. Casinghead The head or top of the casing set in a well.

MISCELLANEOUS C22A-26 The maximum pressure gradient is expected to be .571 psi/ft. Maximum BHP is expected to be .571 x 10,042 : 5,734 psi. The shallowest depth at which abnormal waterflood pressures could be encountered is below the protective shoe. Maximum surface pressure is expected to be 2119 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: C22-26RD, C23-26 and C31-26. 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. RRW/IOIOgOa. ,7-1/2" HOLE 2000 PSI .
