AND BP ) EXPLORATION (ALASKA) ) INC. to amend Conservation ) Orders 195, 223 and 224. ) Conservation Order No. 279 Prudhoe Bay Field Prudhoe Oil Pool March 31, 1992 IT APPEARING THAT: I · ARCO Alaska, Inc. (AAI) and BP Exploration (Alaska) Inc. (BPX) operators of the Prudhoe Bay Unit, by letter dated August 2, 1991, requested the Alaska Oil and Gas Conservation Commission to amend Conservation Order No. 195, Rule 1, and Conservation Orders 223 and 224 to consolidate reporting requirements for the Prudhoe Bay Field, Prudhoe Oil Pool. Notice of public hearing was published in the Anchorage Times and the Anchorage Daily News on August 21, 1991. 3. No protests were filed with the Commission· FINDINGS: I · The Commission established reporting requirements for the Prudhoe Oil Pool waterflood project in correspondence dated March 20, 1981. · Conservation Order 186 as amended by CO 223 establishes reporting requirements for the Flow Station 3 Injection Project (FS3IP). 3~ Conservation Order 195, RUle 1 establishes reporting requirements for the Prudhoe Bay Miscible Gas Project (PBMGP). . CO 165 Rule 9(c) establishes reporting requirements for gas-oil contact monitoring. Conservation Ordeal No. 279 March 31, 1992 Page 2 Se CO 165 Rule 10, as amended by CO 208 Rule 7 and CO 224 establishes reporting requirements for off-water contact monitoring. Internal corporate and technical reporting for the operators is scheduled for the first quarter of each calendar year. The FS3IP and the PBMGP areas receive injectant from the Central Gas Facility. The PBMGP consists of four areas 1) Flow Station 2 Miscible Region (MR, 2) Eastern Peripheral Wedge Zone MR, 3) Western Peripheral Wedge Zone MR, and 4) Northwest Fault Block MR. The FS3IP is surrounded by and contiguous with the Eastern Peripheral Wedge Zone MR. 9, Individual well monthly production volumes (oil, water, and gas) and injection volumes (water, gas, and gas liquids) are filed with the Commission monthly on forms 10-405 and 10-406 respectively. Individual well pressure survey results are reported on form 10-412. 10. Fullscale waterflood began in 1984. 11. Initial efforts to monitor oil-water contact movement were predicated on evaluation of aquifer water influx in the reservoir. Aquifer water influx is restricted by existence of a heavy oil tar-mat at the base of the light oil column and by source waterflooding above the heavy oil tar-mat. 12. Operators have had limited success evaluating water saturation changes in the reservoir behind casing. Low and variable water salinity of produced reservoir water and injected source water have hampered reliability and quantitative estimation of water saturation changes. CONCLUSIONS: I , Consolidating surveillance reports and enhanced recovery project reports will coordinate evaluation efforts and improve efficiency. Conservation Ord~ March 31, 1992 Page 3 No. 279 . Changing the reporting period to coincide with the internal reporting schedule of the Prudhoe Bay Unit operators will eliminate duplication of effort. . Cased-hole logging to monitor oil-water contact movement has so far been inconclusive and is no longer considered beneficial considering the maturity of the waterflood. . Consolidating reports and changing report periods will not cause waste and has no impact on correlative rights. . Raw data (e.g. production/injection volumes and measured well pressures) are reported routinely to the Commission and need not be included in an annual report. . The former FS3IP has been fully integrated into the Eastern Peripheral Wedge Zone miscible region of the PBMGP and is no longer considered a unique project. As such, reference to the former FS3IP and its project area is considered redundant. NOW, THEREFORE, IT IS ORDERED THAT: Rule 1. Conservation Order 223 is repealed. Rule 2. Conservation Order 224 is repealed. Rule 3. Rule 7 of Conservation Order 208 is repealed. Rule 4. Rule 1 of Conservation Order 195 is repealed. Rule 5. Conservation Order 186 is repealed. Rule 6. Rule 9 (c) and Rule 10 of Conservation Order 165 are repealed. Rule 7. Prudhoe Oil Pool Annual Reservoir Surveillance Report An annual Prudhoe Oil Pool surveillance report will be required by April 1 of each year. The report shall include but is not limited to the following: Conservation Ordel A'o. 279 March 31, 1992 Page 4 1) Progress of enhanced recovery project(s) implementation and reservoir management summary including engineering and geotechnical parameters. 2) Voidage balance by month of produced fluids, oil, water and gas, and injected fluids, gas, water, low molecular weight hydrocarbons, and any other injected substances. 3) Analysis of reservoir pressure surveys within the field. 4) Results and where appropriate, analysis of production logging surveys, tracer surveys and observation well surveys. 5) Results of gas movement and gas-oil contact surveillance efforts including a summary of wells surveyed and analysis of gas movement within the reservoir. The analysis shall include map(s) and/or tables showing the locations of various documented gas movement mechanisms as appropriate. RULE 8 Administrative Action Upon its own motion or upon written request, the Commission may administratively amend this order so long as the change does not promote waste nor jeopardize correlative rights and is based on sound engineering principles.

Box 196612 Anchorage, AK 99519-6612 Gentlemen: The referenced application dated August 31, 1993 was received on September 22, 1993. The operators request annual Reservoir Balance tables included in the Prudhoe Oil Pool Annual Reservoir Surveillance Repo.rt (required by CO 279 Rule 7 part 2) substitute for monthly submissions of Form 10-413 as required by 20 AAC 25.432. The Alaska Oil and Gas Conservation Commission has reviewed the application and relevant evidence and finds that Conservation Order 279 supersedes the requirements of 20 AAC 25.432 for filing Form 1.0-413 monthly. The annual Prudhoe Oil Pool Surveillance Report includes a Reservoir Balance table for each EOR project area which includes the same data. It is expected that the tabulation in an annual report will not cause waste nor jeopardize correlative rights. Sufficient information is included in the Annual Reservoir Report and the Reservoir Balance tables to fulfill the requirements of 20 AAC 25.432. In addition, the annual surveillance report will continue to serve as a focal point for reservoir performance and evaluation of trends on an annual basis which is more practical than using monthly reports. Therefore, the Commission, by issuance of C.O. 279, authorized an annual voidage balance (Reservoir Balance tabulation) which can be filed in lieu of monthly Forms 10-413 for each EOR project in the Prudhoe Oil Pool, Prudhoe Bay Field.

Texaco, Shell Western E & P, Marathon, Louisiana Land and Exploration Company and Amerada Hess. Very truly yours, Diana L. Fleck iExecutive Secretary Memorandum State of Alaska Oil and Gas Conservation Commission To: R.A. Douglass ~,~ October 20, 1993 Fm: Jack Hartz ~~ ~' Subj: Request for Waiver to: 20 AAC 25.432 Filing AOGCC Form 10-413 Arco Alaska and BP Exploration have applied for permission to waive one of the requirements of 20 AAC 25.432, filing Form 10-413 monthly. In their request they note that the essence of Form 10-413 is reported annually in the PBU Reservoir Surveillance Report in a table called Reservoir Balance for each of the EOR project areas. Form 10-413 is required by 20 AAC 25.432 and essentially provides a monthly est/mation of reservoir Voidage. Voidage is calculated from standard measured volumes of oil, water and gas produced and injected multiplied by pressure related volume factors to yield reservoir volumes. We do not check these forms nor do they enter into any murine repons that AOGCC provides to the public or other agencies. The rules for operation of the Prudhoe Oil Pool do not specify any limits or standards for reservoir voidage. The Form 10-413 report appears to be useful only in the context of overall reservoir evaluation. The Commission will suffer no adverse consequences by having this reported annually rather than monthly. C.O. 279, issued 3/31/93, consolidated reservoir surveillance reports from the Prudhoe Bay Unit owners into a single report issued to AOGCC once a year by Apr/1 1. The consolidated report is comprehensive and serves to focus on reservoir performance. Rule 7, part 2) requires... "[V]oidage balance by month of produced fluids, oil, water and gas, and injected fluids, gas, water, low molecular weight hydrocarbons, and any other injected substances." One of the exhibits is a Reservoir Balance table for each project area (see attached table). This exhibit replicates form 10-413 by providing a tabulation of reservoir volumes produced and injected and net voidage on a reservoir volume basis. The only differences are that the standard volumes, active wells and pressure basis for the reservoir volumes are not shown on the tabulation. Well counts and area pressure trends are shown elsewhere in the report. The Reservoir Balance tables can be construed to fulfill the requirements of 20 AAC 25.432 and by definition, C.O. 279 supersedes the regulation. Page 2 Conclusions 1, 4 and 5 of C.O. 279 are relevant to this request and are repeated here .... 1. Consolidating surveillance reports and enhanced recovery project repons will coordinate evaluation efforts and improve efficiency. 4. Consolidating reports and changing report periods will not cause waste and has no impact on correlative rights. 5. Raw data (e.g. production/injection volumes and measured well pressures) are reported routinely to the commission and need not be included in an annual report. Whereas C.O. 279 did not specifically address'20 AAC 25.432, it does effectively fulfill the spirit of the regulation by stipulating a report similar to Form 10-413, i.e., a voidage balance which takes the form of Reservoir Balance tables. Conclusions: 1. Monthly reporting of reservoir voidage is not necessary to effectively regulate operation of the Prudhoe Oil Pool. 2. Conservation Order 279 Rule 7 part 2) stipulates an annual tabulation of data comparable to that required for Form 10-413. . Conservation Order 279 supersedes the Form 10-413 requirement of 20 AAC 25.432 by requiting a voidage balance by month as part of th'e annual Prudhoe Oil Pool Surveillance Report. 4. Substitution of the voidage balance (Reservoir Balance tables) for Form 10-413 will not cause waste or jeopardize correlative fights. Recommendation: I recommend the Commission issue an administrative action under C.O. 279 to clarify substitution of the Reservoir Balance tables in the annual surveillance report. Additional data to include in the tabulation can be specified in the AA or in discussions with the operators prior to the next annual submission.

Johnston Alaska Oil and Gas Conservation Commission 3001 Porcupine Drive Anchorage, Alaska 99501 Re: Request for Waiver to: Regulation 20 AAC 25.432 Filing AOGCC Form 10-413 Dear Mr. Johnston: The operators of the Prudhoe Bay Unit, BP Exploration, Inc. and ARCO Alaska, Inc., request a waiver to a portion of the above referenced regulation for the Prudhoe Oil Pool, Prudhoe Bay Field. Form 10-413, Report of Injection Projects, is filed on a monthly basis for several specific project areas and we believe the information contained in these reports is essentially duplicated in other reports currently filed with the Commission. The elimination of the requirement to file FOrm 10-413 will not, in our opinion, adversely affect ultimate recovery, create waste or detract from Prudhoe Oil Pool reporting. Regulation 20 AAC 25.432, Report of Underground Injection, states: "Each operator who injects fluids into subsurface strata through a service well for any purpose, other than fracturing, acidizing or other similar treatment, shall file with the commission monthly reports that show all injected volumes and other data, by well and pool, as required by the commission on forms entitled Monthly Injection Report (Form ! 0- 406), Report of Injection Projects (Form 10-413) and, if applicable, the Producer's Report of Gas Disposition (Form 10-422) .... "We request a waiver only to the requirement for filing the Report of Injection Projects (Form 10-413) for Prudhoe Oil Pool project areas. The information contained on this form, project area production and injection volumes and voidage balance, is essentially a duplication of that supplied for each project area in the Annual Reservoir Surveillance Report for the Prudhoe Oil Pool required under Conservation Order No. 279, Rule 7. The annual report, to be filed by April 1 each year, is to include: '~Voidage balance by month of the produced fluids, oil, water and gas, and injected fluids, gas, water, low molecular weight hydrocarbons, and any other substances." (ref. CO 279, Rule 7.2) This request will not affect the monthly reporting of individual producing well and injection well volumes on Forms 10-405 and 10-406 or the filing of Form 10-422. t~ E C ~ I V'~' [) ARCO Alaska, Inc. is a Subsidiary of Atlantic Richfield Company aJask,a Oil a Gas Cons.

ARCO Alaska, Inc. and BP Exploration (Alaska), Inc. by letter dated August 2, 1991 has requested an amendment to Conservation Orders 195, 223 and 224. The amendment would consolidate reporting requirements for the enhanced oil recovery projects and reservoir surveillance .monitoring required for the Prudhoe Bay Field, Prudhoe Bay Oil Pool and change the due date of the report. A person who may be harmed if the requested order is issued may file a written protest prior to 4:00 pm September 4, 1991 with the Alaska Oil and Gas Conservation Commission (hereinafter the Commission), 3001 Porcupine Drive, Anchorage, Alaska 99501, and request a hearing on the matter. If the protest is timely filed 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 am on September 19, 1991 in conformance with 20 AAC 25.540. If a hearing is to be held, interested parties may confirm this by calling the commission's office, (907) 279-1433 after September 4, 1991. If no protest is filed, the Commission will consider the issuance of the order without a hearing. Russell A.

Johnston, Chairman Alaska Oil & Gas Conservation (AOGCC) 3001 Porcupine Dr. Anchorage, AK 99501 Re: Request to Amend Reporting Requirements for Consolidated Surveillance Report, Water and Miscible Gas Floods, Prudhoe Oil Pool Dear Mr. Johnston: The Operators of Prudhoe Bay Unit Initial Participating Areas, BP Exploration (Alaska) Inc. and ARCO Alaska, Inc., hereby request amendments to Conservation Orders 195, Rule 1, 223 and 224. These Commission documents outline the reporting requirements of the subject Surveillance Report and excerpts of those Conservation Orders are attached for reference. The subject Surveillance Report, currently required to be submitted by September i of each year, is based on data from July i of the preceding year through June 30 of the current year. Our proposal would change the reporting date to April i of each year and would have the Consolidated Report based on data accumulated from January I through December 31 of the preceding year. As earlier discussed with the AOGCC, these proposed amendments reflect the desire of the Operators to further streamline reporting activities in this area of operations by making both internal and external reports coincident. If the proposed changes meet with the AOGCC's approval, we would plan to submit the next report on or before April 1, 1992 and would base it on data covering the 18 month period from July 1, 1990 through December, 1991. Future reports would then follow the revised reporting provisions.
