BP Alaska inc. submitted the referenced application dated July 26, 1973. 2. Notice of the hearing on this request was published in the Anchorage Daily News on August 3, 1973 pursuant to Title II, Alaska Administrative Code, Section 2009, and no protest was received. FIPJDINGS: i. Rule 2 of Conservation Order No. 98-B requires that no pay be opened to well bore closer then 3000 feet to any pay in the same pool opened to the well bore of another well. The applicant requested that the 3000 foot distance be changed to 2000 feet. 2. Accurate directional drilling of a well to a precise target is difficult. 3. The pay section of a deviated well may be perfo rated for production over a horizonal interval of several hundred feet, thereby limiting the permissible target areas for future wells. 4. It is prudent to locate wells to permit future development on a 160 acre pattern if required to increase ultimate recovery of oil. CONCLUSION: The granting of applicant's request wil not result in waste nor impair corre- lative rights of affected parties. NOW, THEREFORE IT IS ORDERED TWAT: Applicant, BP Alaska, Inc. is hereby granted an exception to Rule 2 of Conservation Order No. 98-B to permit the opening of pay in the well bore Conservation Order ~~117-A Page 2 September 7, 1973 no closer than ?_OOO feet to any pay in another well in the same pool in each of the following sections: Township II N - Range 13E, tJ.M.

Homer Burrell, Director Division of Oil and Gas Department of Natural Resources State of Alaska 3001 Porcupine Drive Anchorage, AK 99504 Dear P~Ir . Burrell Atlantic Richfield has no objection to granting BP Alaska Inc. a spacing exception to Conservation Order 117, as it incorporates Rule 2 of Conservation Order 98-B. Specifi- cally, we, Atlantic Richfield, have no objection to BP Alaska Inc. receiving permission to drill any of the nineteen wells referred to in Conservation Order 117 in such a manner that the pay open to production be up to, but no closer than, 2000 feet from the pay open to production in an adjacent well. The maximum distance between wells on a regular 320-acre spacing pattern is approximately 3700 feet. The 3000 foot spacing rule currently in effect requires that direc- tional control be very precise to obtain this regular spacing and not violate the 3000 foot rule on these 320-acre spaced wells. Additionally, many of the original BP Alaska Inc. wells do not conform with a rigorous 320-acre spacing pattern. In order to effect this pattern for the nineteen wells covered by Conservation Order 117.-and any future 320- acre locations, exceptions to the 3000 foot spacing rule are required. It is Atlantic Richfield's opinion that ultimate recovery will be improved if future wells are drilled on regular spacing patterns. Thus we have no objection to this spacing relief request of BP Alaska Inc.

BOX 4-1379 3111 - C - STREET ANCHORAGE. ALASKA 99503 TELEPHONE 1907) 279-0644 August 2, 1973 With reference to our application by letter of July 26, 1973 for an exception to Conservation Order 117 as it incorporates Rule 2 of Conservation Order 98-B to permit a closer well spacing for the nineteen (19) wells referred to in Conservation Order 117 and, further to recent telephone. communications with our Mr. A. K. Howard, we submit the following information for your consideration to substantiate our application. The development scheme proposed for the initial phase of field production is based on the following principles: (1) The area initially being developed is restricted to the thicker part of the oiI column where there might be a later requirement for production or injection wells on a density equivalent to 160-acre spacing. (2) Problems as to the geological configuration of the margins of the oil accumulation are not a primary concern in locating wells internally within this part of the field, and in the thick sand section with low structural dips the area can be treated as grossly homogeneous. (3) The principal concern with well positions in this area then is one of equally spacing wells for drainage, minimum interference, and possible efficiency of recovery from injection processes in the future. (4) The spacing pattern that achieves this is an equilateral triangular (or hexagonal) pattern. Wells should be 5674 ft. apart for 640-acre spacing, 4012 ft. apart for 320-acre spacing, and 2837 ft. apart for 160-acre spacing. It is apparent that a 320-acre pattern cannot be infilled equally to achieve a 160-acre pattern. w r Mr. Homer L. Burrell Director Division of Oil and Gas - 2 - August 2, 1973 (5) As we see a possible need for future 160-acre spacing wells in the middle part of the field, a development location grid has been-drawn in that area on this basis (i.e., 2837 ft. between wells) adjusted as necessary to compromise existing locations. In practice the plan needs constant minor revision as each well is drilled and does not exactly reach target.. For the first stage of development we plan to drill approximately half the locations in this grid and of necessity'(4. above) this does not result in a completely regular pattern. This is not considered significant considering the spacing involved, but does imply that some locations will have to be programmed in theory to be 2837 ft. from existing wells, which, with practical restrictions as outlined in our application by letter of July 26, 1973, may be a somewhat lesser distance.

Our intention at that time, pending the completion of unitization negotiations, was not to unnecessarily request changes in the existing rules unilaterally. It was our expect- ation that we could continue our drilling program honoring the 3000-ft spacing rule, although that rule is not necessarily consistent with any .proposed ultimate development scheme. However, two factors in practice and one in principle have indicated to us-that the procedure is too restrictive and we see considerable advantage and no disadvantage to any party in relaxing this spacing requirement. The factors are (1) the difficulty in drilling a well to a precise target and the reli- ability of directional surveying during drilling; {2) with the deviations achieved and anticipated, the pay section of a well could be required to be perforated for production over a hori- zontal interval of several hundred feet, a factor which restricts the available distance between wells; and (3) although not proven to be necessary, it is prudent to locate present wells to allow in the future for possible regular spacing of wells for production or pressure maintenance on a grid equivalent to 160 acres. We appreciate that the 3000-ft spacing rule was initially adopted to avoid an uneven pattern of development well locations. It is in an effort to achieve this objective that we now feel that this spacing requirement should-be amended. Correlative rights can be protected and ultimate recovery possibly enhanced in this mmanner or, if the State should feel concern in this regard, it could invoke a rule based on Finding 9 of Conservation Order 117. We would therefore request that we be granted an exception to ~~ Conservation Order 117 as it incorporates Rule 2 of Conservation Order 98-B.
