ARCO Alaska, Inc. and Sohio Alaska Petroleum Company, operators of the Prudhoe Bay Unit, by letter dated September 12, 1985, requested the Alaska Oil and Gas Conservation Commission to amend Rules 6 and 11 of Conservation Order No. 165 and Rule 6 of Conservation Order No. 208 to allow administrative approval for extensions and/or waivers of required pressure surveys, ~gas-oil contact monitoring and productivity profiles. · Notice of public hearing was published in the Anchorage Times on September 23, 1985. · There were no protests to the request set forth in the notice of public hearing. FINDING: Innovative well completion techniques for the Prudhoe Oil Pool, both currently used and proposed, and maturing of reservoir performance obviate the ability and need to obtain conventional pressure and productivity profile surveys from these types of wells. CONCLUSIONS: Innovative well completion techniques do not create waste and may enhance ultimate recovery from the Prudhoe Oil Pool. ~ The Alaska Oil and Gas Conservation Commission requires flexibility to administratively approve variances to previous orders to provide the ability to timely respond to changing conditions. Conservation Ord ~o No. 213 Page 2 October 8, 1985 NOW, THEREFORE, it is ordered that: Rule 1. Rule 6(h) of Conservation Order No 165 is amended to read: By administrative approval the Commission may grant time extensions and waive requirements of this rule and by administrative order the Commission may require additional pressure surveys or modify the key wells designated in (c) of this rule and as amended in Rule 1 of Conservation Order No. 208. Rule 2. Rule ll(d) of Conservation Order No. 165 is amended to read: By administrative approval the Commission may waive the requirements of (a), (b) and (c) and by administrative order the Commission may specify additional surveys other than the surveys submitted under (a), (b) and (c) of this rule. Rule 3.. Rule 6 of Conservation Order No. 208, amending Rule 9(f) of Conservation Order No. 165 is amended to read: By administrative approval the Commission may delay, modify or waive the logging requirements of Rule 9 of Conservation Order No. 165 and by administrative order, the Commission may require additional wells to be logged.

Box 196612 Anchorage, AK 99510-0360 Anchorage, AK 99519-6612 Gentlemen: The referenced application was received on April 23, 1993. The request is limited to new wells drilled in the Prudhoe Oil Pool of the Prudhoe Bay Field. Rule ll(a) C.O. 165 requires a production profile Survey in each new well during the first six months the well is on production. A waiver is requested because surveys in wells which are completed in a single reservoir zone or with only one perforated interval provide no meaningful data for surveillance of reservoir zone depletion. The Alaska Oil and Gas Conservation Commission has reviewed the application and relevant evidence and finds that waiving the requirement for productivity profile surveys in the specified wells will not preclude surveillance of zone depletion, will not cause waste nor jeopardize correlative rights. Sufficient alternatives exist to accommodate future surveillance requirements and the Commission may administratively order additional surveys if the need arises. Rule 2, Conservation Order 213 allows the Commission to waive requirements of Conservation Order 165 Rule 11 by administrative order. Therefore, the Commission authorizes waiver of Rule ll(a) Conservation Order 165 for wells completed with a single perforated interval, or with perforations in a single reservoir zone including highly deviated (greater than 65 degrees) and horizontal wells in the Prudhoe Oil Pool, Prudhoe Bay Field.

Box 196612 Anchorage, AK. 99519-6612 Gentlemen: The referenced application was received on January 15, 1993. The request is limited to new wells drilled in areas of the field influenced by waterflood operations where GOC movement is not anticipated. The area of interest is defined as the waterflood/EOR areas encompassed by the expanded Prudhoe Bay Miscible Gas Project outlined in C.O. 290, excluding Drill Sites 4 and 11, including structurally Iow areas west of S and M Pads, and an area east of R Pad adjacent to and influenced by WF/EOR operations. The areas outlined are not expected to have significant GOC movement or gas encroachment from the gravity drainage area. The Alaska Oil and Gas Conservation Commission has reviewed the evidence available and finds that waiving the requirement to run neutron logs in each new well in the specified areas will not preclude monitoring capability, will not cause waste nor jeopardize correlative rights. Sufficient alternatives exist to accommodate future surveillance requirements if the need arises and the Commission has the capability to administratively order additional logs if required.

P O Box 100360 Anchorage, AK 99510-0360 Dear Mr. Scheve: / By your letter dated December 14, 1992, you requested waiver of Neutron logging requirements for the above referenced Prudhoe Oil Pool wells. Acquisition of Neutron log data for the purpose of monitoring gas-oil contact movement, is required of all Prudhoe Oil Pool wells prior to sustained production by Rule 9(a) of Conservation Order (C.O.) 1165. We note that with the exception of injector 4-14A, all the subject wells are located on the downdi.p periphery of waterflood/EOR project areas where no gas-°il contact m. ove~nent issues exist. Injector 4-1.4A will not experience a period of sustained production unless it is subsequently converted to a producer. The requirements of rule 9(a), C.O. 165 will not pertain to 4-14A until that time. The Commission is presently unwilling to waive the requirements of C.O. 165 rule 9(a) for well 4-14A.

We consider that this change will result in more efficient productivity logging in the field through increased operator flexibility to eliminate logs which will not provide useful information, and this change will reduce paperwork associated with individual well waiver requests. Conservation Order 165, Rule 11 (a) states: "A spinner flow meter or tracer survey shall be run in each new well during the first six months the well is on production." We request a waiver to this requirement for wells with specific types of completions under Conservation Order 213, Rule 2, which provides authority to grant administrative waivers to C.O. 165, Rule 11. The primary purpose of Rule 11 was to provide information to assess the effectiveness of well completions to drain the reservoir and to provide baseline surveys for comparison to later logs. Past experience indicates that these initial productivity profiles do not yield significant additional information for this purpose in new wells completed 1) with a single perforated interval, or 2) with perforations in a single reservoir zone. Wells in this second category would include nearly all highly deviated wells, those that exceed 65 degrees from vertical and in many cases are nearly horizontal within a single zone. Individual waivers to this requirement are currently requested for new wells with these types of completions.

We also request your approval to waive the productivity profile requirement for Well B-28, and to extend the productivity profile time period for Well B-26 until after a programmed gas shut-off workover is completed. Well B-28 is producing from a 25 ft., homogeneous, single zone interval and a productivity profile would not provide useful information in this particular cicumstance. Well B-26 is currently producing with high gas/oil ratios and has a near future gas shut-off workover planned to return the well to solution gas/oil ratio production. For this case, we feel that a post workover productivity profile will be more meaningful than one influenced by gas jetting form perforations that will shortly be shut-off.

ARCO Alaska, Inc. and Standard Alaska Production Company, operators of the Prudhoe Bay Unit, by letter of September 26, 1986, have requested changes to Pressure Survey rules contained in Conservation Orders 165, 208 and 213. The objective of the proposed changes is to establish operator flexibility with regard to monitoring reservoir pressure in a manner which will allow the technical value of all surveys to be maximized. A person who may be harmed if the requested order is issued may file a written protest with the Alaska oil and Gas Conserva- tion Commission, 3001 Porcupine Drive, Anchorage, Alaska 99501 and request a hearing on the matter. If the protest is filed timely and raises a substantial and material issue crucial to the Commission's determination, a hearing on the matter will be held at the 'above address at 9:00 a.m. on November 6, 1986, in con- formance with 20 AAC 25.540.

The proposed amendments were discussed with you at our meeting of August 12, 1986. The objective is to establish operator flexibility with regard to monitoring reservoir pressure in a manner which will allow the technical value of all surveys to be maximized. Rule 6 Proposed amendments to Rule 6 are provided in Attachment I. A discussion of these changes follows: (a) We request that the term "initial sustained production" be replaced by "regular production", consistent with the definition of "regular" which was recently officially introduced. In addition, we request that the initial pressure survey requirement can be fulfilled by a pressure transient survey should a pressure transient survey be required for technical reasons. C. V. Chatterton, Chairman Page 2 (b) We request that a pressure static or transient survey may be used to fulfill the follow-up survey requirement since the primary objective of the follow-up survey is to determine reservoir pressure. During the first nine years of production at Prudhoe Bay, a sizeable pressure build-up data base has been established. Routine pressure build-up surveys are no longer required to determine the production characteristics of select areas of the reservoir. In addition, a time limit of twelve months is requested in place of the current six-month limit. An extension of this time limit will provide the operators with additional flexibility regarding repeat pressure survey timing, thus allowing timing to be optimized based on varying increased voidage rates associated with new wells. (c) & (d) Key well and governmental pressure survey requirements limit flexibility with regards to pressure survey site optimization. Pressure surveillance will be distributed in all areas of the field, however, with waterflood underway, the focus of pressure surveillance is now on the waterflood and gravity drainage/waterflood interaction areas. A "minimum number of surveys" requirement would allow application of surveys to areas which require the maximum technical evaluation from a reservoir management perspective. The operators would inform the Commission of the planned distribution of the required pressure surveys by December 1 of the year preceding the year during which the pressure surveys will be run. (e) Included as per Conservation 0rder No. 208, Rule 3 (amending Rule 6(e), Conservation Order No. 165). (f), (g), & (h) These sections have been included and/or modified to be consistent with the changes outlined above and Conservation Order No. 213, Rule 1 (amending Rule 6(h), Conservation Order No. 165). As noted, the primary purpose of the requested amendments is to afford the operators greater flexibility in fulfilling the Prudhoe Bay Unit's surveillance needs and reporting requirements. It does not represent an attempt to reduce the number of pressure surveys required, but does represent an attempt to accomplish a more prudent distribution of required surveys. If you desire any further information in support of the requested changes, please feel free to contact us. D. F. S cheve Arco Alaska, Inc. Attachment T. N.

Standard Alaska Production Company, ' 900 East Benson Bou'l J P.O, Box 196612 Anchorage, Alaska 99519-6612 (907) 561-5111 Mr. C. V. Chatterton, Chairman 0il and Gas Conservation Commission State of Alaska 3001 Porcupine Drive Anchorage, AK 99501 Dear Mr. Chatterton: Standard Alaska Production Company is requesting administrative approval, as outlined in Conservation Order No. 213, Rule 2, to waive required productivity profiles for horizontal wells JX-2, B-30, Y-20, G-29 and high angle wells G-27 and Y-21. Utilizing conventional wireline methods, high angle deviation in these wellbores prevents logging tools from reaching the producing intervals. If you desire further information to support this request, please contact Mr. B. A. Chapman at (907) 564-4114. Very truly yours, TNT:BAC:slh 5224m. , T. N. Tyler, Manager Reservoir 0perations A unit of the or,ginal Standard Oil Company Founded in Cleveland Ohio ,n 1870 September 12, 1985 Mr. C. V. "Chat" Chatterton, Chairman Oil and Gas Conservation Commission State of Alaska 3001 Porcupine Drive Anchorage, AK 99501 Subject: Prudhoe Bay Unit Request for Conservation Order Change Dear Mr. Chatterton: ARCO Alaska, Inc. and SOHIO Alaska Petroleum Company, as Operators of the Prudhoe Bay Unit, request changes in Conservation Order No. 165, Rules 6 and 11, and Order No. 208, Rule 6 to allow AOGCC administrative approval of time period extensions and/or waivers to the pressure survey, gas-oil contact monitoring and productivity profile requirements for individual wells. The completion technique employed, unusual producing characteristics or wellbore mechanical problems can cause delays in obtaining the required data or make it impossible to gather meaningful information. The Prudhoe Bay Unit is presently evaluating the use of high-angle com- pletions, horizontal wellboresand other nonstandard completion techniques to improve recovery in various areas of the field. High angle and horizon- tal wellbores in particular will preclude the running of productivity profiles (Order No. 165, Rule.il) and possibly neutron logs (Order No. 165, Rule 9) with current logging technology. High gas-oil ratio wells present problems in terms of obtaining meaningfql transient pressure data as required by Order No. 165 Rule 6(b). Under these circumstances, the static pressure measurement obtained under Rule 6(a) Order 165 and the pressure data acquired from nearby wells to fulfill government section and key well requirements give adequate reservoir pres- sure monitoring data. Wellbore mechanical problems may also delay or preclude gathering pressure and/or productivity profile data as required in Order No. 165r Rule 6 and 11. Wellbore restrictions, fill or other mechanical conditions can block the passage of wireline tools, influence the producing character of the well, or distort the data obtained. ~Conditions such as these have caused problems in the past in obtaining meaningful information. To increase the flexibility of the Operators and the Commission to deal with individual well problems in a timely fashion, we request Conservation Order RECEIVED SEP ! 6 1985 Alaska Oil & Gas Cuns, Commission A. nchora!/e Mr. C. V. Chatterton!' September 12, 1985 Page 2 No. 165 Rules 6(h) and ll(d) and Order 208, Rule 6 (referencing Order 165, Rule 9) be amended to allow for administrative approval for time period extensions and/or waivers to the requirements of those Rules.
