(c) Production from HGS Oil Pools E, F, and G, as defined in Rule 2, may be commingled in the same well bore, hut must he segre- gated from production from any other pool. Rule 4, Fluid iniection The injection of fluid into any of the pools described in Rule 2, for the purpose of pressure maintenance or secondary recovery or of conducting injecti- vity tes ts, is hen'by perm ¡ tted, subject to the follm·¡ing requirements: \ -" ~ ~ CONSERVATION ORDER #44 Page 4 July 19, 1967 (a) Fluid injected into MGS Pool A must be segregated from and injected separately in the well bore from fluid injection through the same well into any other pool. (b) Fluid to be injected into HGS Pools B, C, and D, may be commingled in the well bore and injected simultaneously into all three pools, but must be segregated from and injected separately in the well bore from fluid injection through the same well into any other pool. (c) Fluid to be injected into MGS Pools E, F, and G, may be commingled in the well bore and injected simultaneously into all three pools, but must be segregated from and injected separately in the well bore from fluid injected through the same well into any other pool. (d) The same well may be used for both injection and producing purposes simultaneously provided that the requirements of Rule 3, and of Rule 4 (a), (b), and (c) above are met, and there is an adequate shut-off between that part óf the well used for injection purposes and that part used for production purposes. Rule 5, L~ase line well The drilling of a well to be completed in the pools defined in Rule 2, at a location as nearly as practicable upon the township line between Township 8 North and Township 9 North and the boundary line separating Lease ADL 17595 from Lease ADL 18754 is hereby permitted, upon a showing being made to the Committee that an approprlate agreement therefor has been entered into by all affected parties, including the State of Alaska as lessor. Said well may be completed and produced as an oil well but shall not be considered as one of the two wells attributable to a quarter section for the purposes of Rule 1 as to either Lease ADL 17595 or Lease ADL 18754. Said well may at any time thereafter be converted to injection purposes. The Committee shall be notified of the è£fective date of the change. Rule 6, Administrative approval of changes in pressure maintenance or secondary recove~y operations The Committee may upon a showing that the operators of each of the leases, as the representatives of all affected parties, concur in the request therefor and that appropriate and adequate casing, cementing, and testing has been, or will be, carried out, authorize any of the following operations as an administra- tive matter and without notice or hearing: , .. , , \.......... CONSERVATION ORDER #44 Page 5 July 19, 1967 (a) The conversion to injection purposes of any well initially completed either as a producer of oil or as a dry hole.

Rule 7, Casing and cementing requirements Surface casing must be set and cemented to a depth of at least 1600 feet. Sufficient cement must be used to circulate to the surface. The production string must be cemented with a sufficient volume of cement to extend at least 500 feet above the shoe or a volume to cover the uppermost pro- ducing zone encountered in the well, whichever is greater. Rule.8, Bottom ,hole pressure surveys An annual key well bottom hole pressure survey shall be made during the months of January and February with the results to be reported to the Committee by the end of March each year, The operators in the field, with approval or the Committee, will determine the datum, the wells to be included, the method to be used and the type of information to be secured. Bottom hole pressures obtained by a static build-up pressure survey, a 24 hour shut-in instantaneous test or a multiple flow rate test will be acceptable for this purpose. Survey results will be reported on Form P-12 or other appropriate means agreed to by the operators and the Committee. .. . , ~. ~ ¡ ~ G ........... CONSERVATION OP~ER #44 Page 6 July 19, 1967 Rule 9, Gas-oil ratio tests A gas-oil ratio test of 24 hours duration shall be made on each producing well annually. The test will be made during the months of January and February and the results will be reported on Form P-9 by the end of March of each year. TI1e requirements of this rule will be waived if monthly reported oil and gas production is based on a gas-oil ratio test made at least every six months by the operator. IT IS FURTHER OP~ERED that Conservation Orders #26 and #31 are superceded by Conservation Order #44. This Order is made pursuant to Section 2061.3 of the Alaska Oil and Gas Conservation Regulations and the rules affecting well spacing shall continue in force for a period of not more than eighteen (18) months pro- vided, however, that wells which have been drilled and completed and are being produced in compliance with the provisions of this Order, or any other Order of the Committee, may be produced in compliance with the terms of said Order not- withstanding the fact that such Order may have eÀ~ired or have been terminated, or that there may be pending a request that said Order be modified or terminated, until such time as the Committee shall, after notice and hearing, enter an Order establishing different rules, requirements, or provisions.

Ross~ On Ha.rch 27, 1975 the referenced application was received which stttted that the request for approval to commingle the D,C, and D Oil Pools with the E,F, and G Oil Pools is based upon the necessity of usina hydraulic pump lift equipment to adequa.tely produce the E,F, and G Oil Pools follm1ing a,cid stih\111ation. 'J'he B,e, and D Oil Pools and E,F, and G Oil Pools both require artificial lift in order to be produced to the surface. The installation of hydraulic þlTGP equipment to produce the E, r, and G Oil Pools precludes the possibili ty of ô dual corapletion because of the restrictions imposed by the casi.ng and pUt"11p sizes. In the event that approval to comrrd.ngle is not s¡i ven, one of the pool groups vmuld be shut-in in favor of producing the more prolific oil pool group. no restrictions ,,,hieh require that the bm pool groups be rnecha,nically seqregated in the ~rel1bore are required.

H G Smith District Manager Amoco Production Company POBox 100779 Anchorage, AK 99510 Dear Mr Smith: On October 26, 1987 the referenced application was received which stated that the request for approval to commingle the "BCD" Oil Pools with the "EFG" Oil Pools is baaed upon the necessity of using hydraulic pump lift equipment. The "BCD" Oil Pools and "EFG" Oil Pools both require arti.ficial lift in order to be produced to the surface. The installation of hydraulic pump equipment to produce the "EFG" Oil Pools precludes the possi- bility of a dual completion beca.use of the restrictions imposed by the casing and pump sizes. In the event that approval to commingle is not given, one of the pool groups would be shut in in favor of producing the more prolific oil pool group. No restrictions which require that the two pool groups be mechanically segregated in the wellbore are required.

Kevin A. Tabler, Manager, Lands Unocal North American Oil and Gas Division P.O. Box 190427 Anchorage, Alaska 99579-0247 Dear Mr. Tabler: The referenced application was received on November 23, 1992. The Middle Ground Shoal, Baker Platform, ADL 17595 Well No. 27 is completed in the BCD pool with a drillable bridge plug isolating the perforations in the EFG pool. The well is ,completed with a dual string to accomodate a pump installation, which necessitates an open annulus to pass produced gas away from the pump. The completion will not accomodate an additional tubing string or a packer to isolate pools. Further, the opportunity to recover "A" pool reserves at this location will exist only for a brief period ' according to current long term waterflood and development plans. In the event that approval to commingle is not granted, the "BCD" pool would be temporarily abandoned in favor of producing the "A" pool prior to subsequent developments. The Alaska Oil and Gas Conservation Commission has reviewed the evidence available and finds that commingling production from the aforementioned pools in this well will allow both to be depleted simultaneously, increase ultimate recovèry from the "A" pool and will not cause waste. The AOGCC expects that appropriate allocation will be done to accomodate determination of recoveries from each pool. ! j.,t,.,d (I~J I ~qT('cd p';n'f?r b Kevin A Tabler November 30, 1992 .

Kevin A. Tabler Manager, Lands UNOCAL North American Oil and Gas Division POBox 196427 Anchorage,AJ< 99519-6247 Dear Mr. Tabler: The referenced application was received on August 13, 1996. The Middle Ground Shoal, Baker Platfonn, ADL 17595 Well No. 15RD is a watered out Hemlock "G" producer which is being recompleted to develop reserves in the Hemlock "A", "BCD", and "EF" zones. Geologic and economic risks require latitude in the completion of this well to develop marginal reserves in mature pools, which would not otherwise be developed by individual segregated completions or multiple tubing string completions. Artificial lift requirements for each pool dictate a packerless completion for efficient operation of the downhole pump nonnally used in Baker Platfonn completions. A single pump installation will be capable of lifting production from all the potential completion intervals and will likely yield additional recovery of oil because individual wells, multiple completions or segregated completions may not be economically justified. The Alaska Oil and Gas Conservation Commission has reviewed the evidence available and finds that commingling production from the aforementioned pools in this well will allow all them to be depleted simultaneously, increase ultimate recovery from the "A", "BCD" and "EFG" pools and will not promote waste. The AOGeC expects that appropriate allocation will be done to accommodate detennination of recoveries from each pooL Therefore, the Commission authorizes the commingling of the referenced production from Well No. 15RD pursuant to Rule 6 of Conservation Order No. 44.

Paul L. Figel Production Engineer XTO Energy, Incorporated 3000 North Garfield, Suite 175 Midland, TX 79705 Dear Mr. Figel: The referenced application was received on August 28, 2001. The Middle Ground Shoal, Platform A MGS AII-OI well is a dual gas lift completion in the subject pools. To date the well cumulative production is 5.03 MMBO in the "EFG" and 1.95 MMBO "BCD" pools. The well has a tubing leak and requires repair. The operator estimates the cost and complexity of a dual, separate completion make the return to a dual completion uneconomic. The Operator plans to lift the producing pools simultaneously and maintain the ability to recover reserves that may otherwise be lost if a workover is uneconomic. Recovery in this well to date represents approximately 92% and 97% of the reserves in the "BCD" and "EFG" respectively. Geologic and economic risks require latitude in the completion of this well to develop marginal reserves in mature pools, which would not otherwise be developed by individual segregated completions or multiple tubing string completions. The Alaska Oil and Gas Conservation Commission has reviewed the data available and fmds that commingling production from the aforementioned pools in this well will allow all them to be depleted simultaneously, increase ultimate recovery from the "BCD" and "EFG" pools and will not promote waste. The AOGCC expects that appropriate allocation will be done to accommodate determination of recoveries from each pool. Therefore, the Commission authorizes the commingling of the referenced production from the "BCD" and "EFG" pools in Well AII-OI pursuant to Rule 6 Conservation Order No. 44.

MGS C41-23LN is being drilled and completed to access reserves that are not being drained by existing wells in this structurally complex portion ofthe MGS Field. MGS C41-23LN will lie entirely within State Lease ADL 018756. The total depth of the well will lie within 150 feet ofthe property line between State Lease ADL 018756 and adjacent State Lease ADL 018754. However, ownership and landownership do not change across this property line. MGS C41-23LN will approach within approximately 300 feet of offset production well MGS A34-14 LW within the HN interval ofthe Hemlock Formation. However, the HN tends to have low porosity and permeability, and the close proximity of the wells is not expected to adversely affect production. MGS C41-23LN does not closely approach offset injection well MGS A33-11LS within the same fault block. Conservation Order No. 44 ("CO 44") governs the MGS Field. Rule l(a) of CO 44 specifies a 500-foot minimum distance to any lease line where ownership changes, and Rule 1(b) specifies that no more than two oil completions shall be allowed in any governmental quarter section. Rule 6 of CO 44 states that the Commission may authorize, as an administrative matter and without notice or hearing, the drilling of additional wells not otherwise authorized by CO 44 for AA 44.74 December 16, 2004 Page 2 of2 e e producing purposes at any location. Administrative approval is appropriate for a waiver of well spacing requirements specified in CO 44. Notice and public hearing are not required for this spacing exception application as the well will lie entirely within State Lease ADL 018756, and will be located more than 500 feet from any lease lines where ownership changes. Correlative rights will not be jeopardized. The Commission has determined drilling and operation of MGS C41-23LN will enhance recovery, will not promote waste or jeopardize correlative rights, is based on sound engineering and geoscience principles, and will not result in an increased risk of fluid movement into freshwater. The Commission hereby approves the drilling and operation of the Middle Ground Shoal MGS C41-23LN well as proposed. December !é2004. --7) 0Æ Daniel T.

FINDINGS: 1. Hilcorp is the operator of the Middle Ground Shoal Field and is the operator of the MGS A44-02 injector well that is located within the Cook Inlet, Kenai Peninsula Borough, Alaska. 2. MGS A44-02 is located entirely within State of Alaska Oil and Gas Lease ADL 18754. 3. MGS A44-02 is currently completed as an injection well in the MGS G Oil Pool. Hilcorp proposes to set a plug above the Hemlock G sand (the MGS G Oil Pool) and recomplete the well as a MGS F Oil Pool producer within an area governed by Conservation Order No. 44. 4. Conservation Order 44, Rule 6, specifies in part that the Alaska Oil and Gas Conservation Commission (AOGCC) may "authorize without notice or hearing ... (c) the conversion from injection purposes to producing status of any well or wells." CONCLUSIONS: The re -completion of MGS A44-02 as a producer will maximize recovery from the Middle Ground Shoal Field, MGS F Oil Pool by accessing un-drained reserves in the oil reservoir that cannot be recovered by existing wells. NOW THEREFORE IT IS ORDERED: The AOGCC hereby authorizes conversion of MGS A44-02 from a MGS G Oil Pool injector to a MGS F Oil Pool producer. DONE at Anchorage, Alaska and dated September 15, 2016. 4Y,,,4- e-(2�r� Cathy/P.

The A24-01LN is not adjacent to a lease boundary and is to be drilled to the steeply dipping west flank of the reservoir. Structural complexities In this portion of the field require producers be drilled at less than 80-acre spacing to insure adequate drainage. After abandonment of the A24-0 1 LE and completion of the side-tract, this well will be the third producer in the SW/4 of Section I-T8N-R13W SM and the only producer in the NW/4 of Section 12-T8N-R13W SM.

Additionally, Unocal requests waiver of the requirement to provide complete separation of flowstreams from separate pools. The AOGCC has granted approval to commingle production in several Middle Ground Shoal wells in the past. Most recently approval to commingle "A", "BCD" and "EFG" pools in the BA-28 well was granted on March 14, 1994 (AA44.53). That approval was very similar to this application insofar as commingling without separation of flowstreams was permitted. RECEIVED t.US 1 3 1996 Alaska 011 & Gas Cons. Commission Anchorage Mr. David JOhnston"airman August 12, 1996 Page 2 e BACKGROUND Unocal purchased Amoco's working interest in several Cook Inlet (Chakachatna) properties and assumed Operatorship of the Baker Platform effective September 1, 1990. Unocal has subsequently acquired the working interests of Texaco and Chevron, and currently holds a 100% working interest in Baker, Anna, Dillon and Bruce Platforms and associated wells. Unocal has aggressively developed reserves at Baker platform since acquIring its ownership. Several recompletions have been performed in attempts to increase production and maintain economic viability from marginal reserves in mature pools. In the case of the Tyonek "A" and "BCD" oil pool at Baker platform, the potential along the east and west flanks is marginal due to the proximity of the oil-water contacts. RESERVES AND DEVELOPMENT STRATEGY Baker 15RD is a watered-out producer originally completed in the Hemlock (G) portion of the "EFG" pool. The original completion has been abandoned and the well has been set up with hydraulic pumping equipment to develop reserves in the "A", "BCD" and "E" & "F" portions of the "EFG" pool. Due to unknown oil-water contacts and waterflooding effects it is quite possible that none or only a portion of the Tyonek "A", "BCD" and "EFG" sands intersected by Well BA-15 will be oil productive. Hence, initial costs and subsequent repair and recompletion costs must be minimized. A hydraulic workover unit was used to prepare the well for recompletion, but only through-tubing methods will be available to add or subtract new production intervals in the future. After receiving approval as applied for herein, Unocal plans to perforate the oil-bearing intervals in both "A", "BCD" and "EFG" pools in Well No. 15 and to commingle production from all perforated intervals. All zones are believed to have similar pressure gradients in this area of the field (0.4- 0.44 psi/ft). WELL EQUIPMENT CONSTRAINTS All oil producing zones at Middle Ground Shoal Field require artificial lift in order to be effectively produced to the surface. Unocal's request to commingle production from the "A", "BCD" and "EFG" zones is based upon the necessity of using hydraulic lift pump equipment. This precludes the possibility of a dual or triple completion because of the restrictions imposed by the casing and pump bottomhole assembly sizes. AUG 1 3 1996 Alaska 011 & Gas Cons. Commission Anchorage Mr. David JOhnston'18irman August 12, 1996 Page 3 e Our request that the AOGCC waive the requirement to provide complete separation of flowstreams is also due to our use of hydraulic lift pump equipment. Experience at Middle Ground Shoal field indicates that production is optimized by producing wells with an open casing annulus to the surface. When the casing annulus is open (no packers installed), produced gas is able to vent up the annulus and does not have to be produced through the hydraulic lift pump. If packers were installed to isolate the pools, all gas produced by the "BCD" and "EFG" pools would be forced through the pump which would lower pump efficiency. Consequently, oil production rates from all zones would be restricted which would reduce ultimate recovery for the BA-15RD well and the Middle Ground Shoal Field. ECONOMIC CONSIDERATIONS After almost 30 years of operations Baker platform oil production (currently 1150 bopd) is very near the economic limit for operation. While Unocal believes that that development potential remains, capital and operating costs must be minimized or further development may be unwarranted. A completion with zonal isolation would be considerably more expensive than packerless completion and would reduce pump efficiency and withdrawal rates for all zones. Subsequent well problems such as sand fill can often be repaired with coiled tubing cleanouts in a packerless completion. A triple or dual completion would require much more costly service rig operations for such remedial work. Due to the mature state of this field Unocal believes that there is little benefit to be derived from continuing to isolate production from the "A", "BCD" and "EFG" pools for the remaining life of the field. PRODUCTION ALLOCATION To allocate production from Well 15RD between the "A", "BCD" and "EFG" pools, Unocal proposes to initially allocated oil and water production in proportion to the amount of perforated interval in each zone. For example, if there are 200 feet of "EFG" zone perfed and 100 feet of "BCD" zone perfed and 100 feet of "A" zone perfed, production would be allocated 50% to "EFG" and 25% each to "A" and "BCD" pools. CONCLUSION In summary, Unocal requests that the AOGCC permit the commingling of oil and gas production from the Middle Ground Shoal Field "A", "BCD" and "EFG" pools in MGS Mr. David JOhnstont,airman August 12, 1996 Page 4 . 17595 Well No. 15RD. Further, Unocal requests waiver of the requirement to provide complete separation of flowstreams from the two zones. It is submitted that commingling will permit more efficient well operations and will not result in waste. Unocal must make its decision whether or not to proceed with perforating the "BCD" pool with the "EFG" tomorrow or the following day. For this reason, your prompt processing of this request would be appreciated. Please direct any technical questions pertaining to this request to Kurt Bair, Reservoir Engineer, at (907) 263-7646. Please notify Dick Crouch by phone at (907) 263-7624 as soon as the approval is granted. Thank you for your assistance. Sincerely, RBC:SKB:dma ri:c01 fj. T U41Át Kevin A.

Î . . '" ~ ;; ;~ . '4 L'...·, :;',' ',. - Dear Mr. Douglass: Union Oil Company of California (Unocal), as operator of the Baker Platform, requests that the Alaska Oil and Gas Conservation Commission (AOGCC) approve the commingling of oil and gas production from the Middle Ground Shoal Field "A", "BCD" and "EFG" pools in MGS 17595 Well No. 28 pursuant to Rule 6 of Conservation Order No. 44. Additionally, Unocal requests waiver of the requirement to provide complete separation of flowstreams from separate pools. The AOGCC has granted approval to commingle production in several Middle Ground Shoal wells in the past. Most recently approval to commingle "A" and "BCD" pools in the Ba-28 well was granted on February 23,1994 (AA44.52). That approval was very similar to this application insofar as commingling without separation of flowstreams was permitted. Background Unocal purchased Amoco's working interest in several Cook Inlet (Chakachatna) properties and assumed operatorship of the Baker Platform effective September 01 1990. Unocal has subsequently acquired the working interests of Texaco and Chevron, and currently holds a 100% working interest in Baker, Anna, Dillon and Bruce Platforms and associated wells. . . AOGCC March 10, 1994: Page 2 Unocal has aggressively developed reserves at Baker platform since acquiring its ownership. Several recompletions have been performed in attempts to increase production and maintain economic viability. Overall Unocal's oil recompletion attempts in the Tyonek "A" and "BCD" pools have been economic failures. It is Unocal's opinion that the only significant remaining oil potential lies in development of the field perimeter. In the case of the Tyonek "A" and "BCD" oil pools at Baker platform, the available perimeter is the northern area of the field along the crest of the anticline. The potential along the east and west flanks is minimal due to the proximity of the oil water contacts. To the south Baker platform borders on a lease held by Shell. In 1993 Unocal undertook a $120MM redevelopment program at the four Chakachatna platforms. Included in that program were 3 new Baker Platform wells one of which (Ba- 28) is intended to assess and exploit the Tyonek A & BCD oil reserves in the north end of the Middle Ground Shoal field. Unocal is now considering deepening the Ba-28 well to the EFG pool but would need permission to commingle production from that zone with "A" and "BCD" pools to justify the deepening of the well. Reserves and Development Strategy In all of the potentially oil productive intervals, the No. 28 well path is designed to intersect the reservoirs as near as possible to the crest of the Middle Ground Shoal structure. Historic performance for both the "A" and "BCD" pools indicates that only completions on the crest of the anticline have yielded adequate oil reserves to justify drilling. However, Unocal has only limited well control in this area for geologic interpretation. Our interpretations as to the position of the crest are based largely upon geological interpretation of seismic data. The nearest well to our proposed Ba-28 completion is Ba-10 which was drilled in 1967. That well was a failure and is believed to have missed the crest of the structure slightly.

AOGCC March 10, 1994: Page 3 Due to unknown structure it is quite possible that none or only a portion of the Tyonek "A" and "BCD" sands intersected by Well Ba-28 will be oil productive. Hence, initial costs and subsequent repair and recompletion costs must be minimized. While adding some additional cost, deepening the well to obtain production from the "EFG" pool should increase the likelihood of obtaining commercial oil production. After receiving approval as applied for herein, Unocal plans to perforate the oil bearing intervals in both "A", "BCD" and "EFG" pools in Well No. 28 and to commingle production from all perforated intervals. If the Baker 28 well is successful, Unocal's long range plans call for conversion of our Ba-27 well to water injection and/or commencing "BCD" injection at our Ba-9RD#2 well (which currently injects into "A" and "EFG" zones) to force oil toward the Ba-28 well. All zones are believed to have similar pressure gradients in this area of the field (0.4-0.44 psijft). Well Equipment Constraints All oil producing zones at Middle Ground Shoal Field require artificial lift in order to be effectively produced to the surface. Unocal's request to commingle production from the "A", "BCD" and "EFG" zones is based upon the necessity of using hydraulic lift pump equipment. This precludes the possibility of a dual or triple completion because of the restrictions imposed by the casing and pump bottomhole assembly sizes. Our request that the AOGCC waive the requirement to provide complete separation of flowstreams is also due to our use of hydraulic lift pump equipment. Experience at Middle Ground Shoal field indicates that production is optimized by producing wells with an open casing annulus to the surface. When the casing annulus is open (no packers installed), produced gas is able to vent up the annulus and does not have to be produced through the hydraulic lift pump. If packers were installed to isolate the pools, all gas produced by the "BCD" and "EFG" pools would be forced through the pump which would lower pump efficiency. Consequently, oil production rates from all zones would be restricted which would reduce ultimate recovery for the Ba-28 well and the Middle Ground Shoal Field. . . AOGCC March 10, 1994: Page 4 Economic Considerations After almost 30 years of operations Baker platform oil production (currently 1640 bopd) is very near the economic limit for operation. While Unocal believes that development potential remains, capital and operating costs must be minimized or further development may be unwarranted. - A completion with zonal isolation would be considerably more expensive than a packerless completion and would reduce pump efficiency and withdrawal rates for all zones. - Subsequent well problems such as sand fill can often be repaired with coiled tubing cleanouts in a packerless completion. A triple or dual completion would require much more costly service rig operations for such remedial work. Due to the mature state of this field Unocal believes that there is little benefit to be derived from continuing to isolate production from the "A", "BCD" and "EFG" pools for the remaining life of the field. Production Allocation To allocate production from Well 28 between the "A", "BCD" and "EFG" pools, Unocal proposes to initially allocate oil and water production in proportion to the amount of perforated interval in each zone. For example if there are 200 ft of "EFG" zone perf'd and 100 ft of "BCD" zone perf'd and 100 ft of "A" zone perf'd, production would be allocated 50% to "EFG", and 25% each to "A" and "BCD" pools. R.

Further, Unocal requests waiver of the requirement to provide complete separation of flowstreams from the two zones. It is submitted that commingling will permit more efficient well operations and will not result in waste. Unocal must make its decision whether or not to proceed with deepening the well beyond the "BCD" pool tomorrow or the following day.

February 11, 1994 Alaska Oil and Gas Conservation Commission 3001 Porcupine Drive Anchorage, Alaska 99501 Attention: David W. Johnston, Chairman Re: Request for Approval to Commingle Production "BCD" and "A" Zones Middle Ground Shoal Field, Platform Baker MGS 17595 Well No. 28 RECEIVED FEB 1 4 1994 Dear Mr. Johnston: Alaska 011 & Gas Cons. Commission Anchorage Union Oil Company of California (Unocal), as operator of the Baker Platform, requests that the Alaska Oil and Gas Conservation Commission (AOGCC) approve the commingling of oil and gas production from the Middle Ground Shoal Field "A" and "BCD" zones in MGS 17595 Well No. 28 pursuant to Rule 6 of Conservation Order No. 44. Additionally, Unocal requests waiver of the requirement to provide complete separation of flowstreams from separate pools. The AOGCC has granted approval to commingle production in several Middle Ground Shoal wells in the past, namely MGS 17595 Well Nos. 4, 5, 6, 7, 14 and 27. The most recent commingling approvals for Well 27 (M44.40 and M44.47) were very similar to this request insofar as comminglin'g without separation of flowstreams was permitted. Background Unocal purchased Amoco's working interest in several Cook Inlet (Chakachatna) properties and assumed operatorship of the Baker Platform effective September 01, 1990. Unocal has subsequently acquired the working interests of Texaco and Chevron, and currently holds a 100% working interest in Baker, Anna, Dillon and Bruce Platforms and associated wells. . . AOGCC February 11, 1994: Page 2 Unocal has aggressively developed reserves at Baker platform since acquIring its ownership. Several recompletions have been performed in attempts to increase production and maintain economic viability. Overall Unocal's oil recompletion attempts in the 1yon~k "A" and~~ªCD" pools have been economic failures. It is Unocal's opinion that the onlysigriiflcant fëm€Ùñìñ9 oil potential lies in development of the field perimeter. In the case· of the Tyonek "A" and "BCD" oil pools at Baker platform, the available perimeter is the northern area of the field along the crest of the anticline. The potential along the east and west flanks is minimal due to the proximity of the oil water contacts. To the south Baker platform borders on a lease held by Shell. In 1993 Unocal undertook a $120MM redevelopment program at the four Chakachatna platforms. Included in that program were 3 new Baker Platform wells one of which (Ba- 28) is intended to assess and exploit the Tyonek A & BCD oil reserves in the north end of the Middle Ground Shoal field. The other two Baker wells have "EFG" pool objectives. Reserves and Development Strategy Historic performance for both the "A" and "BCD" pools indicates that only completions on <. the crest of the anticline have yielded adequate oil reserves to justify drilling. I In both the Tyonek "A" and "BCD" zones, the No. 28 well path is designed to intersect the reservoirs as near as possible to the crest of the Middle Ground Shoal structure. However, Unocal has only limited well control in this area for geologic interpretation. Our interpretations as to the position of the crest are based largely upon geological interpretation of seismic data. ' The nearest well to our proposed Ba-28 completion is Ba-10 which was drilled in 1967. That well was a failure and is believed to have missed the crest of the structure slightly. The BCD portion of the well was not effectively tested and the "A" zone completion produced only 8526 barrels of oil and 2~241 barrels of water before being shut in due to subeconomic 0(1 rates. Due to unknown structure it is quite possible that none or only a portion of the Tyonek "A" and "BCD" sands intersected by Well Ba-28 will be oil productive. Hence, initial costs and subsequent repair and recompletion costs must be minimized. After receiving approval as applied for herein, Unocal plans to perforate the oil bearing intervals in both the "A" and "BCD" zones in Well No. 28 and to commingle production from all perforated intervals.

Economic Considerations Baker platform oil production (currently 1400 bopd) is very near the economic timit for operation. While Unocal believes that significant potential remains for development of the EFG pool, the remaining potential for the "A" and "BCD" pools is limited (ie perhaps one or two more wells). The capital and operating costs for remaining development must be minimized or further development may be unwarranted. Due to the mature state of this field Unocal believes that there is little benefit to be derived from continuing to isolate the "A" pool production from the "BCD" pool production for the remaining life of the field. RECE'VED, FEB 1 4 1994 Alaska Oil & Gas Cons. Commisllon Anchorage . . AOGCC February 11, 1994: Page 3 - A completion with zonal isolation would be considerably more expensive than a packerless completion. As discussed above a packer system would also reduce pump efficiency and withdrawal rates for both zones. - Subsequent well problems such as sand fill could be repaired with coiled tubing cleanouts in a packerless completion.

For example if there are 200 ft of "BCD" zone perf'd and 100 ft of "A" zone perf'd production would be allocated 2/3 to "BCD" and 1/3 to "A". Conclusion In summary, Unocal requests that the AOGCC permit the commingling of oil and gas production from the Middle Ground Shoal Fields "A" and "BCO"zones in MGS 17595 Well No. 28. Further, Unocal requests waiver of the requirement to provide complete separation of flowstreams from the two zones. It is submitted that commingling will permit more efficient well operations and will not result in waste. Unocal estimates that this well will reach TO in approximately 30-45 days.

If successful, this well shall be the fourth producing oil well drilled in the southwest quarter of Section 31, Township 9 North, Range 12 West, S.M.. I enclose Figure #1, Top Hemlock Structure with Well Courses, and Figure #2, Cross-section of Baker #29. The approximate spud date is September 7th, 1993, as set forth in the accompanying Permit to Drill. Unocal interprets a separate fault block to exist on the west flank providing a Hemlock reservoir which is at least partially isolated from existing producers and injectors to the east (See Figure #2 - Cross Section Ba-29). Oil reserves in the extreme southwestern portion of Unocal's lease will not be recovered unless a new oil producing well is positioned west of Ba-20. Subject to the performance of the 8a-29 well, Unocal plans to convert well 8a-23 to water injection to improve pressure maintenance and waterflood sweep efficiency along the west flank of the structure. Pursuant to 20AAC 25.055, Unocal has notified Shell Western E&P Inc., operator of the offsetting quarter section to the south, of this request for variance.

Douglass Fro: Jack Hartz ~ Subj: Unocal Request to Commingle II All and liB Zone Production at MGS Baker Well NO.2 November 25, 1992 I reviewed Unocal's request to commingle production within the tubing and wellbore in the above mentioned well. The request is predicated on an opportunity to capture reserves in the A zone prior to expanding waterflood operations in that zone and developing locations updip if economics and well performance justify it. This opportunity exists only until updip locations are developed and Well 27 is converted to water injection. The operator plans to allocate BCD zone production according to it's historical trend. This method of allocation is reasonable in that there is no way to measure production profiles downhole because of the completion. The proposal alludes to economic constraints which are credible. The anticipated recovery from the A zone is not great enough to justify an additional completion within the same wellbore, nor can it justify its own well. The operators proposal will enhance the ultimate recovery from thl3 zone and field by capturing reserves at minimum capital expense. . Commingling is a valid development alternative when zones are nearing depletion and opportunities like this should be encouraged. Ample precedent is available in this field and elsewhere in other pools. Recommendation The proposal should be approved with the caveat that production be allocated to both zones in an appropriate manner. I can write a draft AA for your signature if you prefer. =#31 ' .

Issuance of the requested Order would be an exception to 20 MC 25.215 (b). Additionally, Unocal requests waiver of the requirement to provide complete separation of flowstreams from separate pools as specified in 20 MC 25.210. The commission has granted approval to the previous operator (Amoco) to commingle production in several Middle Ground Shoal wells in the past, namely MGS 17595 Well Nos. 4,5,6,7,14 and 27. The previous commingling approval for Well 27 (M44.40) was very similar to this request insofar as commingling without separation of flowstreams was permitted. RECEIVED -.

Johnston November 20, 1992 Page 2 Background Unocal purchased Amoco's working interest in several Cook Inlet properties and assumed operatorship of the Baker Platform effective September 01, 1990. Unocal has subsequently acquired the working interests of Texaco and Chevron, and currently holds a 100% working interest in Baker, Anna, Dillon and Bruce Platforms and associated wells. MGS 17595 Well No. 27 is presently completed in the "BCD" zone. The well was initially completed in the "EFG" zone in 1984. In November, 1987, in accordance with AOGCC Administrative Approval No. 44.40 the well was completed in the "BCD" and production was commingled with the "EFG" zone. In 1991 during a well repair, Unocal temporarily abandoned the "EFG" zone below a bridge plug set at 9950' KB and the "EFG" zone remains in that status. Since the 1987 completion of the "BCD" zone, Well No. 27 has recovered approximately 400,000 barrels. The current production rate is 69 bopd at 78% watercut. Water analysis indicates that the produced water is natural formation water and is not related to current or historic water injection. Remaining oil reserves for the BCD zone are estimated at 54,000-59,000 barrels. Reserves and Development Strategy In both the Tyonek "A" and "BCD" zones, the No. 27 well intersects the reservoir on the northeast flank of the Middle Ground Shoal structure. Historic performance for both zones indicates that completions on the flanks of the anticline (eg., Ba-13, Ba-16 & Ba-27) are prone to early natural water influx and normally yield less reserves than crestal locations. Although Ba-27 is expected to produce at high initial rates (200 bopd + ) there is a strong possibility of rapid water influx. After receiving approval as applied for herein, Unocal plans to perforate the "A" zone in Well No. 27 and then commingle production from the "A" and "BCD" zones. Unocal anticipates oil production to increase by 200 bopd as a result of adding the "A" zone pay. If the Commission does not grant approval to commingle, Unocal intends to temporarily abandon the "BCD" zone, which would reduce the ultimate recovery for the Field. Unocal's long range plans call for drilling wells to the north and west which would be updip of this well in both the "A" and "BCD" zones. If the updip locations are successful, the No. 27 well would eventually be converted to water injection to force oil upstructure to the new producers. If the well is produced from those zones now, it will allow Unocal to capture downdip oil as the underlying aquifer expands and encroaches into the productive sands. . . Mr. David W. Johnston November 20, 1992 Page 3 RECEIVE r..I....)\I 2.· "2 1QQ~".' {'~t. '3.. \.Ì !i:V"~ Well Equipment constraintSt\¡aSka au & Gas Cons. The "BCD" and "A" zones both require artificial lift in order to be effectiv~C~o/ð~uced to the surface. Unocal's request to commingle production from the "A" and "BCD" zones is based upon the necessity of using hydraulic lift pump equipment. This precludes the possibility of a dual completion because of the restrictions imposed by the casing and pump bottomhole assembly sizes. Our request to be granted waiver of the requirement to provide complete separation of flowstreams is also due to our use of hydraulic lift pump equipment. Experience at Middle Ground Shoal field indicates that production is optimized by producing wells with an open casing annulus to the surface. When the casing annulus is open (no packers installed), produced gas is able to vent up the annulus and does not have to be produced through the hydraulic lift pump. If a packer were installed to isolate the "A" zone from the "BCD" zone, all gas produced by the "BCD" zone would be forced through the pump which would lower pump efficiency. Consequently, oil production rates from both the "BCD" and "A" zones would be restricted which would reduce ultimate recovery for the Middle Ground Shoal Field. Economic Considerations Baker platform production (1000 bopd) is currently very near the economic limit. Hence costs are also a factor in Unocal's request. A completion with separated flowstreams would be considerably more expensive than a single producing string completion. Subsequent well problems such as sand fill could be repaired with coiled tubing cleanouts in a packerless completion. A dual completion would require more costly service rig work to cleanout sand. Considering the possibility that this well could incur rapid water encroachment (due to its structural position) recompletion and subsequent operating costs must be minimized. Production Allocation To allocate production from Well 27 between the "A" and "BCD" zones, Unocal proposes to initially allocate 69 bopd and 180 bwpd of the well test production rate to the "BCD" zone. As shown on the attached performance curves for Well No. 27, production is currently declining exponentially at annual rates of 23% for oil and 15% for water. Correspondingly, Unocal would reduce the allocated "BCD" production at these decline rates. Considering that the "BCD" produces at such low oil rates, Unocal submits that this plan of allocation will be satisfactory and that no waste will occur. . . Mr. David W. Johnston November 20, 1992 Page 4 Conclusion In summary, Unocal respectfully requests that a Conservation Order be granted by the Alaska Oil and Gas Conservation Commission to permit the commingling of oil and gas production from the Middle Ground Shoal Fields "A" and "BCD" zones in MGS 17595 Well No. 27. Further, Unocal requests waiver of the requirement to provide complete separation of flowstreams from the two zones. If the Commission does not grant approval to commingle the two zones Unocal intends to temporarily abandon the "BCD" zone in favor of producing the "A" zone which would reduce ultimate oil recovery from the Middle Ground Shoal Field. Unocal is planning to perform the necessary work in January or February 1993. For this reason your prompt processing of this request would be appreciated.

The information provided on Form 10-409 "Well Status and Gas-Oil Ratio Tests" is sufficient to preclude need for the test. Thank you for the additional reservoir information.

(SWEPI) would like to confirm compliance with the gas-oil testing requirements of rule 9 of the AOGCC Conservation Order #44 dated July 19, 1967. Conservation Order #44 defines the field and pool rules for the Middle Ground Shoal field and authorized the initiation, expansion and continued pressure maintenance or secondary recovery operations. Rule 9 states: "A gas-oil ratio test of 24 hours duration shall be made on each producing well annually. The test will be made during the months of January and February and the results will be reported on Form P-9 by the end of March each year. The requirements of this rule will be waived if monthly reported oil and gas production is based on a gas oil ratio test made at least every six months by the operator." Gas-oil ratio tests are performed each time we test a producing well and allocated oil and gas volume data and gas-oil ratios are reported on our Monthly Production Report (AOGCC Form 10-405). The Monthly Production Report (Form 10-405) is submitted in compliance with AOGCC Regulations as outlined in Alaska Administration Code, Title 20 - Chapter 25, Article 3, Section 230. Oil rates for the Monthly Production Report are determined from 12 hour well tests via a test separator and are typically done at least three times each 30 days on each completion. As all producers at Middle Ground Shoal are assisted via gas lift, produced gas rates are determined during the production tests by subtracting the input gas lift injection gas from the total output gas venting from the test separator. Twelve hour tests are considered more than adequate for accurate and consistent well test data at Middle Ground Shoal and are used as our primary surveillance information. Our understanding is that the frequency of our gas-oil ratio tests exempt us from the requirements of an annual 24 hour test as provided for by the waiver clause in Rule 9. Providing the information requested on Form 10-409 (previously Form P-9) is redundant and increases the administrative load on both the AOGCC and SWEPI as operator. It is also our understanding that the : _....-':::">.""......... ......-' , "-,~ . primary objective of Rule 9 is to avoid abnormal reservoir pressure depletion through excessive reservoir voidage. Attached for your information is a time history plot of our production and injection rates including a calculated voidage replacement curve (liP = injection/voidage, expressed in %). This plot illustrates that we have maintained a "positive" (greater than 100%) voidage replacement on Platforms "A" and "C" since mid 1969. By way of this letter we are requesting your concurrence that the requirement of an annual 24 hour gas-oil ratio test is waived in accordance with rule 9 of Conservation Order #44. If you wish to discuss or have questions, feel free to contact Paul Huckabee of our staff at (907) 263-9646. Very Truly Yours, ~ R. G. Blackburn Manager Alaska Operations Shell Western E&P Inc.

G. Smith District Manager October 26, 1987 Alaska Oil and Gas Conservation Commission 3001 Porcupine Drive Anchorage, Alaska 99501 Attention: C. V. Chatterton, Chairman File: FEW-134-WF Gentlemen: #,~ Request for Approval to Commingle Production from the Middle Ground Shoal Field IIBCDII and IIEFGII Zones in MGS 17595 Well No. 27, Amoco Production Company, Platform Baker Amoco Production Company, as operator of the Chakachatna Group of companies, respectfully requests that a Conservation Order be granted by the Alaska Oil and Gas Conservation Commission to permit the commingling of oil and gas production from the Middle Ground Shoal Field IIBCDII and IIEFGII zones in MGS 17595 Well No. 27. Issuance of the requested Order would be an exception to 20 AAC 25.215 (b). Additionally, Amoco respectfully requests waiver of the requirement to provide complete separation of flowstreams from separate pools as specified in 20 AAC 25.210. MGS 17595 Well No. 27 is presently completed in the MGS IIEFGII zone. As shown on the attached performance curve, currently Well No. 27 is producing 30 BOPD. As soon as we receive approval to commingle production from the II BCDII and II EFGII zones, we plan to perforate the II BCDII zone in Well No. 27 and commingle production from the two zones without installing any packers to separate the flowstreams. We anticipate oil production to increase 250 BOPD as a result of adding IIBCDII pay and commingling production from the two zones. If the Commission does not grant approval to commingle, we would temporarily abandon the IIEFGII zone, which would reduce ultimate oil recovery from the Middle Ground Shoal Field. ~\, , The IIBCDII and IIEFGII zones both require artificial lift in order to be produced to the surface. Thus, our request to commingle production from the IIBCDII and IIEFGII zones is based upon the necessity of using hydraulic lift pump equipment which precludes the possibility of a dual completion because of the restrictions imposed by the casing and pump bottomhole assembly sizes. The Commission has granted approval to Amoco to commingle production in several Middle Ground Shoal wells in the past, namel~E~C¡SIVED' 17595 Well Nos. 4, 5,6, 7, and 14. K It OCT 2 7 iSö7 Alaska Oil & Gas Cons. Commission Anrhn.... ' . . Alaska Oil and Gas Conservation Commission File: FEW-134-WF October 27, 1987 Page 2 Our request to be granted waiver of the requirement to provide complete separation of f10wstreams is also due to our use of hydraulic lift pump equipment. Based upon our experience, production is optimized by producing wells with an open casing annulus to the surface. When the casing annulus is open, that is when no packers are installed, produced gas is able to vent up the annulus and does not have to be produced through the hydraulic lift pump. If a packer were installed to isolate the "BCD" zone from the "EFG" zone, all gas produced by the "EFG" zone wou1 d be forced through the pump which would unnecessarily lower the hydraulic lift pump efficiency. Consequently, oil production rate from both the "BCD" and "EFG" zones would be restricted which would reduce ultimate oil recovery from the Middle Ground Shoal Field. To allocate production from Well No. 27 between the "BCD" and "EFG" zones, we propose to initially allocate 30 BOPD of the well test production rate to the "EFG" and the remainder to the "BCD". As shown on the attached "EFG" performance curve for Well No. 27, oil production is presently 30 BOPD, but is declining on an annual decline rate of 46 percent exponential. Correspondingly, we would reduce the allocated "EFG" oil production at this decline rate. Considering that the "EFG" zone produces such low rates, we submit that this plan of allocation will be satisfactory and that no waste wi 11 occur. To summarize, Amoco Production Company respectfully requests that a Con- servation Order be granted by the Alaska Oil and Gas Conservation Com- mission to permit the commingling of oil and gas production from the Middle Ground Shoal Field "BCD" and "EFG" zones in MGS 17595 Well No. 27. Additionally, Amoco respectfully requests waiver of the requirement to provide complete separation of f10wstreams from the two zones. If the Commission does not grant approval to commingle the two zones, Amoco would temporarily abandon the "EFG" zone in favor of producing the "BCD" zone, which would reduce ultimate oil recovery from the Middle Ground Shoal Field. We prefer to perform the necessary workover to commingle the two zones in Well No. 27 before year end; therefore, your prompt processing of this request is appreciated. Very truly yours, ,': øJJ:~ W.

Wells C-31-23 and C-32-23 are the two permitted "G" Pool producers in the NE/4, Sec. 23-8N-13W, SM. Attached is Form 10-401 and related data for drilling of the proposed well. The proposed well is located in an area of leaseholds owned in undivided 1/3 interests by Shell, Chevron, and ARCO. As shown in the attached plat, the location is approximately 3480' from the nearest lease line to the west. Justification for this well is based upon the recovery of additional oil and gas reserves which would not otherwise be produced within the economic life of the project. The additional drainage point is designed to achieve a better balance in the operation and enhance the pressure maintenance program and sweep efficiency. Your early consideration will be appreciated to enable prompt use of an available rig. Yours very truly, JFW:DW ~f- R. Planty .

We have also located the boundary between Sections 14 and 23 at about 6,900 feet south on the directional plot by Drilling Services Inc. a copy of which was included with the completion data transmitted to you by our letter, October 14, 1976. It is now apparent that this well was inadvertently drilled and can... p1eted beyond the spacing limit without a prior application for an exception location. However, it appears that the present completion will serve to op'" timize recovery and that waste would occur as a consequence of plugging and renewed drilling operations.

Also attached is our Application for Permit to Drill MGS 17595 Well No. 9 Redrill 2, and our draft in the amount of $100.00.

We consequently plan to plug back the No. 9 Redrill wellbore and side- track to a more favorable producing location upstructure. The bottom hole location for No. 9 Redrill 2 will be the third well- bore in the southwest quarter of Section 30 and is within 1000' of the nearest producing well. Movement of the wellbore to this location is necessary to provide a1Q{)!:e favorable p:¡::gducing lQ,c:_ation to optimize recovery from the Middle Ground Shoal Field based upon the geologic data now available from No. 9 Redrill.

Marshall, Jr. Gentlemen: In response to the telephone conversation on June 30, 1975 with Shell's Mr. K. W. LaGrone, relative to rule G of Conservation Order 44, we are supplying additional information for the subject drilling program. Wells C24-l4 and A34-l4 are producing at lower and less efficient rates than nearby producing wells in the same relative structural position and are performing unsatisfactorily, we believe, due to reservoir imp~irment and damage which we have, to date, been unable to overcome. A recent in-depth review of the MGS Waterflood performance and an updated reservoir simulation have shown that one well, suitably placed near the existing C24-l4 location, will provide a more,efficient drain~ge point than both the existing wells A34-l4 and C24-l4; both in terms of better producing rates and greater ultimate oil recovery. The well density in the southern part of Section 14 is effectively reduced since one well will be replacing two. The MGS study and simulation also indicated that there will be a significant volume of oil remaining in the "G" Pool sands between existing wells C3l-23 and C23-23 and the bounding westerly fault(s) at the conclusion of the waterflood, due to lack of a drainage point in the vicinity of the 22-23 location. The well density in this part of Section 23 is effectively greater since one well is being added. Overall, the field well density is unchanged; however, expected better well conditions (both mechanical and reservoir) and better position relative to expected significant unswept oil accumulations will greatly improve the sweep and drainage efficiency in both areas and increase the ultimate oil recovery from the field. This program, we believe, is vital to enable our continuing efforts in support of energy development and natural resource conservation. ,. . . State of Alaska Division of Oil and Gas 2 I trust that this information is sufficient to warrant your administrative approval of our recently submitted applications to drill at the bottomhole locations indicated.

This approval would be an exception to Conservation Orders Nos. 44 and 53 which pro- hibit the commingling of oil and gas produced from the "BCD" zone with that produced from the "EFG" zone. Shell Oil Company is the operator for the only other affected parties and a copy of their mailgram indi- cating no objection to the proposed rule exception is included as part of this application. Administrative approval was previously granted on a similar completion per your letter of October 25, 1974. This excep- tion allowed commingling production for MGS 17595 Well No.7. MGS 17595 Well No.5, located 1930' FNL, 536' FWL, Sec. 31, T9N, R12W, S.M., is presently completed in the MGS Oil Pools "BCD" and "EFG." Both zones are presently produced by gas lift at very low rates due to we11- bore damage incurred during the initial completion of the well. The Chakachatna Group has approved a well repair procedure which calls for reperforating and acidizing both the "BCD" and "EFG" zones above 8650'. If this application is approved, the well will be completed with the "BCD" zone commingled with the "EFG" zone and pumped with hydraulic lift equipment to produce the well at the maximum capability of both zones.

C. .~~~ MGS 17595 Well No.7, located 659' FSL, 804' FWL, Sec. 31, T9N, Rl2W, .' ,ß.¡<i S.M., is presently completed in the MGS Oil Pools "A," "BCD" and "EFG." The "A" zone production is commingled with the "BCD" zone and both zones are produced by gas lift. The "EFG" zone is not capable of producing due to we1lbore damage incurred during the initial completion of the well. The Chakachatna Group has approved a well repair procedure which would shut off the "A" zone production by cement squeeze and acid stimu- late the "EFG" zone. If this application is approved, the well would be completed with the "BCD" zone commingled with the "EFG" zone and hydraulic pump lift equipment installed to produce the well at the production rates expected following the workover. ',. e . - 2 - Our request for approval to commingle thè "BCD" zone with the "EFG" zone is based upon the necessity of using hydraulic pump lift equipment to adequately produce the "EFG" zone following the acid stimulation. The "BCD" and "EFG" zones both require artificial lift in order to be pro- duced to the surface. The installation of hydraulic pump equipment to produce the "EFG" zone precludes the possibility of a dual completion because of the restrictions imposed by the casing and pump sizes. In the event that approval to commingle is not given, one of the zones would be shut-in in favor of producing the more prolific zone. If approval is given for the requested commingling, we request that~ ~, restrictio which require that the two zones be mechanically se re ated ~~ '~. .... ... --.-..-: - -_.~- in the wellbore ~:ulç~~eg. }'1j!t9-_.thfi 9L1Q.r!?;V~ ..:" ec anJ.ca segregation -ot two cómminglëd zones to prevent flow from ooe zone to the other during long-term shut-in periods and to permit periodic testing of each of the zones has been required in past approvals granted by the Conser- vation Committee. We request relief of this restriction at Well No. 7 for the following reasons: 1. In order to mechanically segregate the two zones in the wellbore, a packer must be set between the "D" zone and the "E" zone with flow control equipment installed in the tubing. The packer setting depth at Well No. 7 would be appro~imately 7450' and the hydraulic pump must be set above the packer at about 7430'. By eliminating the packer, the pump could be set at about 7970', immediately above the liner top. The "EFG" zone production would be increased as a result of the lower pump depth due to the lower bottom hole pres- sure against the "EFG" zone (equal to 530' TVD of fluid). Also, we are seriously considering the use of electric submersible pumps in the MGS Field. A submersible pump with the flow rate and lift capacity needed to draw down the well can be run inside the liner and again, "EFG" production would be increased as a result of the lowered bottom hole pressure. 2. We have encountered severe calcium carbonate scale deposition in several wells in the MGS Field and suspect that scale control will be required at Well No. 7 to maintain "EFG" zone production at maximum rates. We are able to successfully inhibit scale deposi- tion by continuously injecting a chemical scale inhibitor into the casing annulus. The chemical must be dissolved in the produced water to prevent the calcium and carbonate ions from coming into contact with one another and precipitating. By setting a packer above the "EFG" zone, the chemical could not circulate across the "EFG" zone and scale could precipitate in the tailpipe. Scale deposition in or around the tailpipe would restrict the "EFG" production rate and could eventually completely plug off the tail- pipe. fI' . .. . e '...

The area to which the proposed well will be drilled contains four injection wells and one production well (see attached map). The cumulative injection for these four injectors is approximately one-sixth of the total water injected in the SAS portion of the field. The producer, A 14-1, is located in an updip position and will not provide adequate drainage of the oil located downdip from it. The proposed A 24-01 will be located in the downdip area of the pattern and will improve the sweep efficiency of this area. As a result an improved recovery of oil from the field will be rea 1 i zed.

"EFG" from production to water inj ection service, in accordance with the provisions of Rule 6 of Conservation Order No. 44 and for an exception to the commingling provisions of Conserv~fon Orders No. 44 and No. 53 for MGS 17595 Well ~o. 6to permit commingling of oil and gas produced from MGS Oil Pool II A 11 with oil and gas produced from MGS Oil Pool II BCD II . On behalf of the Chakachatna Group of companies, we request administrative approval by the Alaska Conservation Committee of the captioned Application. Shell is the operator for the only other affected parties. A copy of Shell r s letter indicating no obj ection is a part of this Application. The waterflooding program for the "EFG" interval on Lease 17595 needs to be supplemented by additional water injection capacity which can be efficiently provided by 17595 Well No. 4 located in the SW/4 NW/4 of Section 31-T9N-RI2W. Injection Well 17595 No. 12 "G" has a 4,000 barrel per day injection rate, and No. 14 "G" can accommodate 2,000 BWPD for a total of 6,000 BWPD. Since No. 12 is a lease line well, the effective "G" zone injection on Lease 17595 is only 4,000 BWPD. In terms of the anticipated gain from the waterflood, it is desirable that about 60 to 70% of available water be inj ected into the "G" zone. This would be an injection rate in the range of 12,000 barrels per day. The "EFG" section in Well No. 4 is expected to provide a high injection capacity, at least 6,000 barrels per day. This would bring the total injection into the "G" zone to 12,000 barrels per day which, together with 6,000 into the "BCDEF", and 2,000 into the "A ", would account for the full inj ection capacity of the system. " ~. March 7, 1973 Page 2 File: LLH-119-986.511 Well No. 4 is currently on artificial Uft by gas lifting. The "A" zone, which is now commingled with the "EFG" , will be squeezed with cement prior to installing the injection tubing and commencing water injection operations. The well contains adequate casing which has been cemented but will be tested further before using it as an injection well. All injection operations will be carried on in accordance with the provisions of Conservation Order No. 44. Producing wells completed in the "EFG" on Lease 17595 have reservoir withdrawals approaching 'the reservoir volume of injected water. The desired reservoir pressure increase from w~ter- flooding has not been realized. At present two wells, 17595 No. 12 and No. 14, provide the only water injection into the "G" zone. While the injection capacity of the two wells is substantial, additional injection into the "G" zone on Lease 17595 is needed to insure a positive withdrawal balance and provide maximum oil recovery from the "EFG" producing interval. Well No.4, when converted to injection, will provide this needed additional inj ection . MGS 17595 Well No. 6 located in the SW/4 NW/4 Section 31-T9N-R12W, is presently completed in MGS Oil Pools "B", "C" and "D". Rule 3, Permissible Commingling, of Conservation Orders Nos. 44 and 53, prohibits commingling of oil and gas produced from MGS Oil Pool I! A" with oil and gas produced from other defined pools in the Middle Ground Shoal Field. Applicant requests relief from said Rule 3 for its MGS 17595 Well No.6 in order to open the "A" pool in this well so as to provide more efficient lift of the oil produced from the commingled "A II and II BCD" intervals in this well. Since the 7" producing casing in this well imposes physical limitations on downhole producing equipment, Applicant proposes a single 3-l" tubing completion with a packer located above and a packer located below the MGS Pool "An. The packers will provide positive control for the commingled production of MGS Oil Pools "A" and "BCD" in this well. In case of extended shut down of production, the two producing intervals will be segregated. MGS Pools "A" and "BCD" will not be produced in MGS 17595 Well No.4, a twin well at the same location with Well No.6. Commingling the "AI! and "BCD" producing intervals in Well No.6 will provide more efficient utilization of gas lift gas and gas lift equipment available on MGS Platform "B" , which will result i~ more efficient oil recovery, thereby preventing waste. Alaska Oil & Gas Conservation Committee Order No. 99 provided that semi -annual production tests may be made by utilizing spinner surveys to measure the proportional amount of production to be allocated to the respective commingled production intervals. It is respectfully requested that similar provisions be applied to production testing required at Well No.6. Upon initial completion, a 24 hour production test will be obtained on the "BCD" and a 24 hour production '" "-" March 7, 1973 Page 3 File: LLH-119-986.511 test will be obtained on the II A II and II BCD II zones commingled and the tests will be filed with the Committee. Thereafter semi -annual production tests utilizing spinner surveys will be taken and filed with the Committee. The Chakachatna and SAS companies are the owners of all leases and wells within the area covered by Conservation Orders No. 44 and No. 53 which would be affected by the Committee I s order herein and are also the owners of all leases and wells within one-half mile from the outer boundary of said area. The pa~ties above named are therefore the only affected parties other than the State of Alaska, as Lessor, and are the only parties entitled to certified notice of the filing of this Application in accordance with Section 2154 of the Oil & Gas Con- servation Regulations.

As I have mentioned to those who were here that we have had a little recording trouble. This is a Public Hearing by the Alaska Oil and Gas Conservation Committee on an application by Pan American Petroleum Corporation and Shell Oil Company, for a Conservation Order which would, (one) provide certain field rules for the development of part of the Middle Ground Shoal Field, (two) authorize secondary recovery operations ......in the same area, and (three), supercede Conservation Order 131. On the Committee here today are Mr. Marshall, our Executive Secretary; Mr. Wallington and Mr. VonderAhe, members; Mr. Gilbreth, and Mr. Kugler, technical advisors and Mr. Crews, legal advisor. My name is Williams. Notice of this hearing was published on July 3, and then republished on July 8 because of a typographical error in the first notice, however, ten days notice are sufficient for a hearing of this nature. No protests against this . application have been filed. The applicants requested that a hearing not be held if no protests were received, but since they introduced the matter of secondary recovery in their application, the Committee decided that a hearing should be held. Also, some suggested guide lines on additional subjects are. being initiated by the Committee,which will be brought out. and put on record during this hearing. This is the first ttme that field rules of this nature will have been adopted, which adds to the importance of this matter. Witnesses will be sworn in and will identify themselves for the record. I believe this concludes my opening remarks, and I presume the Pan American Petroleum people would like to proceed; they seem to be in preponderence here tonight. (Laughter) I ThII~'" ~ by Div. ofM & Mnrls '""" MvIeum I Page 4 - MR. ROBISON: Mr. Williams, and members of the Committee, I might identify myself. I'm Paul Robison of Robison, McCaskey and Strachan, local counsel for Pan American Corporation. Mr. Oscar Swan, who has appeared before you previously, attorney for Pan American Corporation, will actively participate for the appli- cant, and the included group. Mr. Swan-- MR. SWAN: Might I make a brief opening statement7 I think it will shorten the Hearing and clarify some points on which there may be some doubt. MR. CREWS: Prior to your making your opening statement, Mr. Swan, could I ask you and Mr. Williams that if all persons who have or are interested ib this hearing, been personally served or waived a personal service? MR. SWAN: MR. CREWS: MR. St-lAN : MR. CREWS: MR.. SWAN: They have actually joined in the application, is my understanding. All persons? Yes, the seven applicants are the-- There's no one else? --only interested parties. Isn't that your understanding, Joe? MR. RUDD: Yes. MR. MARSHALL: We've received a Waiver For Personal Service. MR. SWAN: Are you picking me up alright now? MR. CREWS: I believe that is all I have. MR. SWAN: We have had two previous hearings with respect to field rules, and the Committee about a year ago did enter a temporary order, establishing field rules and giving some variation from the statewide 160-acre spacing rule. In the previous hearing the Chackachatna group, which I represent, and the SAS group) which will be represented by Mr. Rudd, differed only on the matter of t~e. I think if you will read the records of the previous hearings, as far as the basic facts are concerned, there was no difference between the testimony of the witnesses for the various parties. I think that the records of those two ¡ '""" """'-. ... :.....-. bv 1ìi v ()f'M Rr M nr 1 ~ ftom """"""" Page 5 previous hearings should be made a part of the record in this case. We .would ask that that be done. I think if you do that, it will shorten some of the testimony we h~ve. We have prepared our case pr~ar1ly as a supplement to the previous testimony. It will simply save going into a lot of engineering detail that I don't think is necessary at this time, because it's already been gone into. MR. WILLIAMS: Yes, we will accept the record of the two preceding hearings as part of the record of this hearing. MR. SWAN: We are asking now for a permanent order. Under your rules you first enter a temporary order. We feel that we now have sufficient definition of the field, and sufficient information about the field, so that it is now proper to enter a permanent order under which the field can be operated for the future. Now this doesn't mean,that the order can't be changed. The Commission of course retains continuing jurisdiction. What it does mean is that this order will remain in effect until for good cause and on notice and hearing, the Commission sees fitted, or the Committee sees fit to change it, so that we will not have to come back in another eighteen months for another hearing. We feel that we do have sufficient information now for a permanent'order. We feel that we should now be permitted to drill two wells upon each quarter section; the engineer will go into the reasons why we feel "this should be permitted. We also feel that we should be permitted to initiate secondary recovery operations by fluid injection. Quite frankly, at this time, until we've done a little more work, we can't assure you that the secondary recovery operations will prove successful, but certainly we have enough information to indicate that now's the t~e to try it and to see if we can successfully conduct such an operation. Under the circumstances, we can't tell you exactly how it's going to work. For that reason, we need considerable administrative flexibility in conducting this secondary recovery operation. There will be necessity from time to time, perhaps, to drill wells in addition to the two wells permitted on each quarter section or to convert a producing well to an injection well, or convert it back the other way. We can't even tell you which í _L '__ ___A...... ___.1_...1 L.. T"\.: 'n ,...{! ~ Ir 0_ 'I\. Ir ..._1 .... "___ ~_._ I ',,- _' Page 6 wells this would effect; but we have asked in the order that changes such as this, and some other changes we will point out later, be approved as an adminis- trative matter, if there is no objection from any of the interested parties. Now, all of the interested parties are applicants here, and perhaps the best way to explain what we are trying to get at would be to talk about an example. Take for example, if Pan American felt that it needed to drill an additional well on the acreage it's operating, the first thing, of course, we would have to do would be to check with the other three members of the Chakachatna group, Sinclair, Skelly, and Phillips and make sure that they agree with us, because the four companies, each, have an equal vote in everything we do. So right there, the operation is checked by four independent sources, and I assure you that each of our partners makes up his own mind. They don't rely on us any more than we rely on them in matters such as this. Then the next thing would be, we would go to Shell as the operator for the SAS group, tell them what we want to do, if they agree with us, they would then go to the other two members of their group, see if they agree. There again you have three other companies that will each conduct their own independent study. If, then, we're all in agreement, we would present the matter to the Committee. If the Committee felt that it was proper, they could grant it without further notice and hearing. If, on the other hand, the Committee felt, as you felt in this case, that the matter was of sufficient importance th~t I: a hearing should be held, of course you can always have a hearing on it, and of course if the two group s could not agree on a particular matter, either group is perfectly free to ask for a hearing on any question. We feel that this gives sufficient flexibility so that we can initiate this secondary recovery operation and conduct it in the most efficient manner, and at the same time it protects <:::J everybody concerned; that is, all of the seven companies have a voice in every decision that is made and the State itself has in effect a veto power on every decision that is made, and these are the only parties that would be affected by anything that is undertaken. There is one more point I might bring up. At the tfme we prepared this application, we included only the area that would bé developed by the A, B, and C Platforms in the Middle Ground Shoal Field. A and ~ ~ Pqe7 C Platforms are operated by Shell for the SAS group, and the "B" platform by Pan American for the Chakachatna Group. There is a 4th platform on this same general structure. The "D" platform operated by Pan American for the Chakachatna group. When we started preparing this application, we thought it was premature to include the area that would be developed from the "D" pl~tform operated by Pan American for the Chakachatna group. When we started preparing this application, we thought it was premature to include the area that would be developed from the "D" platform. We now feel that it is not only not premature, but that it is proper, and at this time to ask that that area also be included. In other words, we feel that the area developed from these four platforms should all be developed under the same rules. The same rules should apply throughout the whole area. Now, I realize that your Publication Notice has not described this additional acreage. It would be our suggestio~, if the Committee agrees with us, that it is now proper that. you enter whatever order you feel is proper and include this area, and then publish a notice stating that the area has been included, and that the decision to include it will become final, unless someone protests its inclusion within ten days. Frankly, the only persons who will be affected· by the inclusion of this additional acreage, are the seven companies who are joining in this applica- tion, and the State itself. So, actually, everybody who has any real right to object is here represented in the Hearing today, so we do not believe there would be any objection to it. We believe this would be a simple way to handle it. I have one witness. Mr. Rudd would you like to make an opening statement before we start1 MR. RUDD: If I may just very briefly. MR.. WILLIAMS: Stand near the mike. MR. RUDD: Simply, very briefly, like to state--I would like to state the position of the SAS group with Shell as operator. For the record, my name is Joseph Rudd; Ely Guess, Rudd & Havelock, representing the SAS group. As Mr. Swan has noted, this is in effect a continuation of the hearings that were held I .........&...-___..:..-.......... T'\i 'U nf \A' R. ~A' n.,..l Q ..............._ last summer which resubred in Conservation Order #31. Page 8 kf' the time of those hearings, the SAS group was opposed to an 80-acre spacing pattern or density, almost entirely on the ground of ttming. At that ttme the SAS group did not feel that enough information from drilled wells and from information that could be gathered from production history was available to justify altering the State-wide rules at that time. Now several months have passed and a number of wells have been drilled and completed and production history on the older wells has continued long enough, and has become full enough so that the necessary information has been derived, and the SAS group now feels that it is time for the adoption of a field rule that will permit drilling two wells to the quarter section;:and we feel that it is also ttme to commence the feasibility studies of the actual field operations in connection with secondary recovery projects. As Mr. Swan noted, the exact nature of the secondary recovery project can't be stated. Not only that, but its actual effect cannot be stated at the moment. It is necessary to enter into studies and actually operate one or more wells as an input'well in order to make t~ese calculations and final determinations. In view of this, we have asked for rules which necessarily have some flexibility in permit~ing development of secondary recovery operations. We feel that this flexibility, particularly in view of the ltroited number of affected parties, is entirely proper and that it will not invade or limit, the Commission's power to supervise the ~perations in regard to public interests. I note finally, that as to Mr. Swan's last subject, the inclusion of the South Middle Ground Shaol unit area in the area to be covered by this rule, the SAS group concurrs with that proposal, and ~hatever procedure by way of publication may be necessary, of course, is acceptable to us. We wil~ after Pan American has completed their testimony, and presented their exhibits, also have a witness and he will testify and present an exhibit on behalf of Shell. MR. SWAN: May I now proceed with my witness? . MR. WILLIAMS: Mr. Swan, yes. MR. SWAN: Will you be sworn in? I this ~ .. ~ by lli v. ofM & Marls from MoIeum I -- ,,-" Page 9 MR. MARSHALL: Please raise your right hand. In the matter·now at hearing, do you swear to tell the truth, the whole truth, and nothing but the truth, so help you God? MR. DARSOW: I do. MR. SWAN: Before I commence with this witnesses' testimony, since there is a great deal of engineering detail in the record, we have tried to omit as much of that detail as we could and still give you a coherent story here today. If you feel we are not giving you enough detail on any point as this witness proceeds through his testimony, please interrupt me and we'll expand it. LEONARD DARSOW being first duly sworn under oath, testified as follows on DIRECT EXAMINATION BY MR. SWAN: Q Will you state your name' please? A Leonard Darsow. Q By whom are you employed, Mr. Darsow? A I'm employed by Pan American Petroleum Corporation. operating out of the Denver division· office in Denver, Colorado. Q What. position do you hold with Pan American? A I am a Petroleum Engineer in the Reservoir Section. Q As a part of your duties do you work with the engineering problems in the Middle Ground Shoal Field? A Yes, 'I've been assigned to follo~ the Reservoir Phase of our Middle Ground Shoal operations for the past 18 months. o You are then familiar with that Field? A Yes, I am. Q' Have you previously testified before this Committee? A No. I ...~ ..........._. .. :..-.1--'.... 1\.1 "IT "of '~A' ~. ~A' ..,.,..1 co '- ........__ I Page 10 Q Would you state just briefly for the record"what your training, your education training and experience has been as an engineer? A Yes, I graduated from MOntana School of Mines, located in Butte, MOntana, in 1958, receiving a Bachelor of Science degree in Petroleum Engineering. Following graduation, I, since that time, have been employed with Pan American. My experiences with Pan American have been divers~ied, having field operations, operating problems and reservoir training. I have been in and associated with the Reservoir Section for the past five years. Q May his qualifications as a expert witness be admitted? CHAIRMAN WILLIAMS: We will accept these qualifications. Q Mr. Darsow, are you familiar with the application pursuant to which this hearing is being held? A I am. Q You assisted in the preparation of it, did you not? A Yes, I did. Q Do you have some exhibits which you have prepared to illustrate your testimony in this case? A I do. Q Would you step up to the wall and where those exhibits are, and lets just run through it; explain what each of them shows. Tþe first exhibit Mr. Darsow, what is it? What information is'shown on it? A The first exhibit that I would like to discuss and present today, we have of course labeled as Exhibit 11. Our Ixhibit 11 is a structural contour map. Contoured with reference to mean sea-level. Contoured on top of the y~S Oil Pool A. The definition for the MGS Oil Pool A, has been covered by and defined by previous Conservation Orders Number 26 and 31. On our Bxhibit'i 1 in the heavy dashed lines, we show the outline of the area for which field rules are requested. As Mr. Swan has pointed out, the preparation of ~his exhibit, and the time of preparation, the exhibit does not show the inclusion I Thk'W"'O-,..:.....w....... 1ìi v n fM R.,. M n,.l ~ 'rom P'etnll1IUI'/t I .~ Page 11 of the area covered by the South Middle Ground Shoal Unit, which is contiguous and extends to the South. Also, on. this exhibit, through a means of a color code, we indicate the ownership within our proposed field rule area. The yellow color signifies the acreage, whose working interest is controlled by the Chackachatna group. Mr. Swan pointed out that Pan American is operator of this group, composed of Pan American; Skelly. Sinclair, and Phillips. The light tan color code represents the area whose working interest is controlled by the SAS group, operated by Shell and containing the members of Shell, Standard of California, and Atlantic. The contour interval shown, we are showing a 500' contour interval in our heavy line, the dashed lines represent our interpretation of fault positions,. as they intersect the contoured interval. In addition, you will note, we are showing three cross-section lines. These cross-section lines. These cross-section lines represent exhibits which we've covered later on in our test~ony. The AA prtme line is a cross section through the Chackachatna Well 17595 #5 and 19. The BB pr~e cross section will represent a cross section through the Chack Wells 17595 #8 and 417. Following our testimony, the Shell Oil Company will present aecross sectionCC pr~e which goes through their Wells A-32-1l, A-42-1l and A-23-l2. Our exhibit also depicts the location of the permanent platforms now under operation or under construction, The Chackachatna Platform "B", the SAS Platform "A", and the SAS Platform "Cu. Our Platform "D" in the South Middle Ground Unit area is not shown on this exhibit, but is located in the South-East quarter of the South-West quarter of Section 35, Township 8 North, Range 13 West. From the two permanen~ platforms where operations are under way, we've also shown the, by means of a dashed line, the well bore trace of all platform w~lls drilled. Bottom hole location represented and depicted by our legend is either being producing wells, suspended wells, or drilling wells at the time these exhibits were prepared, which was June 16, 1967. I Thlt~, It ~Ited t., Div. of M & Marls from Mvleuml ~ <~,/ Page 12 Q Essentially, Mr. Darsow, is Exhibit #1 an updating of exhibits which were used in the previous hearings? A Ye's, it is. In the previous hearings, with regard to spacing rules for Middle Ground Shoal, a structure map was submitted 'as evidence which was contoured on top of the middle Kenai oil zone. This middle Kenai oil zone has since been defined as the MGS Oilpool "Au, and the two zones are one and the same. Q Well, now, referring to .Exhibit.;: 2, which is a similar exhibit. What inform~ ation is shown on that? A . Our Exhibit #2, is also a structural contour map. The basic detail is exactly the same. Or the basic background is· exactl~ the same as Exhibit #1. The only difference being, that in Exhibit 2 we are now contouring on top of the . MGS Oilpool "G". This also is a oil pool defined by Conservation Orders #26 and 31. All other data, the platforms, the well bores, lease ownership are identical. Q Mr. Darsow, in your opinion have sufficient wells been drilled within the area shown on Exhibits 1 and 2, which can be developed from the A & B Plat- form, so that we can now say that the field is reasonably well defined in that area? ~7 A Yes, they have, The fact .that our two exhibits are based µpon well control, points this out, that sufficient wells have been drilled from the SAS Platform "A" and the Chackachatna Platform "B" to have defined the overall Middle Ground Shoals structure in this area. This can be pointed out on the Chackchatna ac~eage by the fact that our Well No.. 9 on the east side near the dry hole encountered non-productive intervals. The same applies to our Well #8 drilled on the west side of the structure. The wells drilled from the SAS Platform "Au on the west side have encountered and cut a fault similar to fault cut by our Chackachatna west-side wells, giving us a location for the west-side limits. Referring back again to the east side, we find that some ¡ ThIo clc>cu..-t .. ~ bv lJi v _ () f 'NT Rr M n r 1 ~ from "-,",,euII'I I '_ .......v' Page 13 of the SAS lower structural wells drilled to the east are encountering a change in permeability, tightening of the reservoir rock, and are approaching and defining, and have defined the eastern ltmit of this field. Q Within the area which can be developed from these two platforms) have wells now been drilled on each quarter section that is likely to be proven product- ive'1 A Yes, all quarter sections have been drilled. Q Then, under the order as it now stands, no additional drilling could be undertaken in that area. A That is correct. Q In your opinion, should additional drilling be done in that area? A Additional drilling, I believe, is indeed necessary. Q Would you tell us some of the reasons why you believe additional drilling should be done? A I think to clarify this point, if I may, I would like to refer to my next two exhibits, Exhibits #3 and 4, which are the cross sectional configurations that I've mentioned earlier. First, I would like to discuss with you Exhibit 3, which is a cross section AA Prtme, drawn west to east direction through the Chackachatna Well 17595 #5 and #9. This exhibit is drawn on a lit equal 200 foot scale in both the vertical and horizontal direction, so that you have depicted here is a true cross sectional representation of what our interpretation is. Along the left border of our exhibit, we are showing the datums with reference to mean sea level. We are also depicting the actual well bore trace of Well #5 and Well #9. We are indicating by a solid line the fault positions which we have interpreted from our well data. We are also projecting into this cross section,' the section line which separates Section 25 from Section 30. We are also showing the quarter section line to show that one width on l60-acre spacing rule encompasses the productive limits I TNt """"-'f It ~ by Div. of M & Marls from ~ I '---' Page 14 of the Middle Ground Shoal Field underlying the Chackchatna acreage. To go on with this exhibit, wefve also shown the 7 MGS oil pools as defined. We have our seven zones colored in a color scheme repre- senting the comingling orders which are in existence. The A zone partly is separate from the other zones. The B,C, C pools are cominglable, as are the E,F, and G. We are also depicting a line representing a productive limit for the upper pools. We, are showing this with a question mark in that the contacts, the oil w~ter contact, if you will, for these upper pools, have been determined from log calculations. The calculations have not been confirmed by testing of any specific wells, that is, you can see we have no wells in that specific area of the contacts to do any testing. So we have shown our well water ltmits as questionable in that they have not been confirmed. Q Do you have essentially the same type of information on Exhibit 4, but just through different wells? A Yes, I do. The Exhibit 4 cross section BB Prime, is essentially one mile to the south o'f our Exhibit 3, and is drawn through Chackchatna Well 17595 #8 and #7. The same configurations are shown to the State zones. The interpretation, of course, ties in with the actual well bores drilled. We see that Well #7's well bore was drilled through the crest of the structure. Well #8 was located to the east, cut a fault rather high in our--with relation, to our seven zones, seven pools, and then encountered a extremely complex, high-dipping, non- productive area of the field. Dips toward the bottom of the well bore in Well #8, approach 850. To define the structure a little more in referring to these exhibits, I should point out that the structure is steeply dipping anticline. On the east side we find in these two positions that the structure falls off, approaches ~ips in the 45 to I n... ___I .. :.......dr.d.... n¡ v {\f'M R.r M n r 1 ~ from...troIeum '.........' Page 15 500 range before encountering a fault. In comparing Exhibit 3 with Exhibit 4, we can get a three dimensional effect by going from one exhibit to the other and keeping in mind that Exhibit 4 is one mile to the south. For instance, if we look at the East fault with reference to the quarter section line, we see that the fault in this vicinity of the field is encountered at approximately a minus 8800' foot datum. As we go one mile south, with reference to the same quarter section line, we find that this fault is now encountered at approximately the minus 10,000 foot datum. So we see that as we come south on the Chackachatna acreage, the east fault plunges rapidly as we go south. We see later that this fault is not of consequence as we get further south. The position in studying the fault to the west is very s~ilar. A fault is not a fixed position in any three dimensional view, and by studying these two cross sections we can see as we go from north to Ii south, that the fault does tend to move, and moves slightly in this area to the west. Q Well now, why, from the type of reservoir shown by Exhibits 3 and 4, do you feel that additional wells would be advisable within the area that can b~_7developed from the first two platforms. ~ A· From these two cross sections, we can see that the productive limits are in essence confined within the width of the quarter section. As a result, one well has been drilled into the productive limit, the second well, which was in the adjoining quarter section, encountered non- productive areas. We see that both cross sections represent the productive well having been drilled on the crest of the structure. When we look at the amount of productive area available, we can see that we have from 800 to 1,000 feet of oil saturated column, particularly in the "G" Pool, lower than any point penetrated by existing wells. For I ..... ......~. .. :.-..a-o.... n; u ,..,of 'iA' ~T ~A',.,.,...1 Q ,_ -...1_ I ~.- '-" Page 16 this reason it would help a great deal to have a field rule which would allow two wells per governmental quarter section, so that the second well' could be drilled, and that we could penetrate the complete productive interval. Q Is this additional well most important for primary recovery, Mr. Darsow, or for potential secondary recovery possibilities? A It can apply to both, the major import$nces would be involved with the secondary recovery. Q On that point, do you have an est~te or an opinion as to what per- centage of the original oil in place might be recovered from this field through primary production methods? A Yes, I do. From the data that we have gathered from the wells drilled to date, their performance, the cores taken and the study of the cores in our labs, the type of reservoir we have, which is an expansion or depletion drive reservoir, it would be my estimate. that the primary recovery in the Middle Ground Shoal Field would be in the 15 to 20% range of oil in place. Q Assuming that secondary recovery operations are undertaken and proved successful, have you any opinion 8S to what additional percentage of the original oil in place might be recovered? A Yes, I would say in a range of a 10% of oil-in-place increase, in other words, that with secondary, with a successful pressure maintenance secondary project, we could expect the recovery factors to increase from the 15 to 20 percent area to the 25 to 90% range. Q Are you of the opinion that this field has now reached the stage in its development at which secondary recovery operations should be seriously considered and undertaken if ,possible? A Yes, they should. 1_ .... ~'U ,....ç'?.iT (). ?iT........lco '-........__1 ~..7 Page 17 Q Have, or has, there been an exchange both of . information and ideas between I: the two groups, that is, the Chackachatna group and the SAS group, with respect to conducting a field-wide secondary recovery operation in this field? A Yes, Pan American, representing the Chackachatna group, and Shell, representing the SAS group, have met and have discussed the prospects, the v possibilities, the considerations to be included in a secondary recovery operation. Q Just in general, well, first, are the companies then in agreement that such operations should be undertaken? A Yes, they are. Q In general, how would it start? Or how would you propose starting it? A The initial steps to be undertaken with regard to secondary in Middle Ground, would involve the permission of the Commission to procede with injectivity tests and the drilling of the lease line injection well. This lease line well can be shown referring to Exhibits I ør 2 . . . is located directly on the lease line separating the Chackachatna and the SAS group acreage. The current proposal is that the injection well would be located approximately 1200 feet from the southeast corner of Section 31, Township 9N, Range 13 West. Range 12 West, pardon me. Q What would be the fluid to be used initially for injection purposes? A The proposal would be to initiate injection using water. Q Is it possible that in the future it may be found desirable to use other injection fluids, either to replace or to supplement· the water. A This is possible. Q And should the order be sufficiently broad so that it would permit the injection of any fluid ... upon approval of the Committee? A Yes it should. Q Let's ..... referring to the application, Mr. Darsow,maybe we better take [ _. . . . ~ __. OA ___..1............. L.... 'r\.; .. .. ,....ç~". Q_ ~"........lC'O a-.........__ I ......."... Page 18 working interest owners and to the royalty owner, that down the line, in the future, should a platform failµre occur and should remaining oil in our ~ools be too small to justify rebuilding, we would have an economic advantage by having higher cumulative at that time. Fourth: Is the overall platform economics. The investments involved with permanent platform constructions, associated submarine pipeline is extremely high. The payout of these invest- ments is extremely critical to the operator. The sooner the operator can 1\ pay these investments out, realize a return, the sooner he will have the capital available for reinvestment into other similar projects. And, Number 5, which I am leaving to last, but certainly is one of our most important...is the additional flexibility wé will gain to conduct secondary recovery. The fact that we have such a complex reservoir in this particular area is exhibi~Jd by Exhibits 3 and 4. We find that one well per governmental quarter section simply does not allow us the flexibility to be able to assume a conformance factor under secondary to be able to 'contact enough of the reservoir to 'improve our success. The fact that we would have two wells per governmental quarter section would give us this flexibility and control we need. Q Well, now going on to the next proposed rule in the application, which is Rule 2, Pool Designation...and it is essentially, I think, exactly a repeti- tion of Rule 3 of present Conservation Order 31...would you recommend any change in that rule at this time? A Not at this time. Q Is 'it possible that some change may be necessary or desirable in the future? A Yes, in the future, a possible change in the commingling order could be recommended, primarily.when we consider the MGS Oilpool "A". The Oilpool "A" has been segregated, and, under existing Conservation Orders, would be produced by itself on the basis of testing conducted in the Chackachatna 17595 Well Number 4. However, sustained production ,has not been undertaken in any of the existing platform wells, and when this should occur, if the I Tnla document .. ~ by Di v. of 'M & M nr 1 s frvm '-"'01_ I Page 19 ~ "~ information found at that time would indicate that commingling would be permissible, it should be considered. -" Q There simply isn't any evidence at this time to justify such a change? A No there's not. Q Well, now, proceeding on to the next rule; Rule 3, proposed in the applica- tion, which...is a repetition of Rule 3, of Conservation Order 31, with respect to permissible commingling of the zones, you have illustrated the permissible connningling in Exhibit 3 and 4, have you not? A I have. Q And do you recommend any change in the permissible commingling at this time? A No, I do not. Q Alright...back to the prior orders. Rule 4....1 think that, is more of a legal problem. In effect, we are saying that, anything that was legal when it was done, continues to be legal. You agree that that should be adopted, '" \ .J do you not? A I agree. Q Now, going on to the secondary recovery, and paragraph number 4 of the application sets out the information which is required by the rules to' be submitted to the Committee in order that a secondary recovery operation may be approved. Did you assist in the preparation of the material which was, submitted under paragraph number 4 of the application? Ii A I did. Q Gentlemen, this information is all in the application itself. It's a verified application. I don't want to take'a lot ofttme in going into the detail of it. If you have any questions on any of the items, Mr. Darsow c:--7 would be happy to elaborate on it, but basically I think that paragraph ¡/4 is self-explanatory, and I don't want to take your time up duplicating __/'1 information. CHAIRMAN WILLIAMS: No questions at this time. I n... ___I" :.....1...11'" nhT nf M R.~ l\¡fn-rl ~ "- '-traI_ '" A Q A Q Page 20 Q }m. SWAN: There is one exhibit we have which elaborates to some extent on this paragraph and that's Exhibit 5, which does show how this would be complet- ed. Mr. Darsow, would you refer now to Exhibit 5 and explain that one to us? A Yes, I would. My Exhibit #5 is a schematic well bore diagram of the proposed lease-line well for the Middle Ground Shoal Field. What we are depicting by this exhibit is simply the down-hole portion of our proposed lease-line well and how we will mechanically complete and operate this well. We are showing the seven MGS oil pools again in the proporable color codes as explained earlier for commingling purposes. We are showing the casing and cementing proposal involved with this well. Our proposal would be to drill and cement 9 5/t.. casing at approximately 7,.350 ft., then drill on and set a 7" liner to TD which would be through the "G" Pool. The 9 5/8" casing·would he cemented to cover the MGS Oil Pool "A" and the 7" liner, the cement would be circulated. We would then proceed with running two strings of tubing, a dual packer set isolating the "A" & liB" Pools, a single packer set to isolate the "D" &"E" Pools. The lower pools are "E,F, & G", could then be produced and injected into through the long string. The "B,C, & D" Pools could be produced or injected into through the short string. Would this proposed completion adequately protect all produciable zones from the top of the "A" on down? Q It would. And, would it permit injection into all of these producible zones? Yes. Now, going on to the specific rules proposed in the application. Under paragraph number 5 of the application, Rule No. 5 says: The injection of fluid into any of the pqols described in Rule 2 for the purpose of conducting pressure maintenance or secondary recovery, or of conducting injectivity. tests is hereby permitted subject to the following requirements....and then. there follows paragraphs A,B, and C, which in effect .requiré that injected fluids be segregated in the same manner as produced fluids. And paragraph D I ~. '\'"'\.:... ,...c'ÍI./r 0_ ~/r.........lco '--_a-i-_ I Page 21 '-"" ~ which says that the same well may be used for both injection and produéing purposes simultaneously provided that the requirements of Rule 3 and Rule 5, A, B, and C above are met, and there is an adequate shut off between that part of the well used for injection purposes and that part used for production purposes. First, are you of the opinion that the injection of fluids into these pools should be permitted for pressure maintenance or secondary recovery purposes or for conducting injectivity tests1 A Yes Q We haven't gone into much detail on this injectivity test. What are you ("7 ~ ~-;--) " -' .:'..,- talking about when you say, conducting injectivity tests1 A The opportunity or rule to cover" the allowance of injectivity tests is desired to again utilize the flexibility for us to proceed with actual injections of fluid into our reservoirs, into our pools in order to determine the pressure, the volumes of fluid that càn be injected as the secondary project is studied. The pressure volume measurements obtained in injectivity tests will allow us to properly size injection equipment, etc., as the secondary project proceeds. Q Well, actually your injectivity tests are in essence a starting of injection to see if it will work. A That is correct. Q And, at this time c~n you be sure whether the injectivity tests will be conducted before a lease line well,is drilled) or whether the reverse will be true? A Not at this time. Q Is it. possible, ~ctually, both might, will be undertaken practically simultaneously? A It is. Q Well, now proceeding to the next rule which provides for the drilling of a lease line well, you have already testified ~bout that lease line well and I tI>Io___lI~bv niv_ ofM & Mnr]~ from~ I Page 22 _c '~ shown its location.....ln addition to its use for injection purposes, that is to increase recovery, would this lease line well serve another purpose? A Yes, it would. Q Hhat is that purpose? ~ A By drilling and locating a injection well on the lease line, and by success- fully injecting water into it, we find that we would establish and form a barrier on the lease line in the vicinity of the lease line to prevent the migration of oil across that lease line. In this way the equities of both ('It!:) Q tbe Chakachatna and SAS group and the royalty owner would be preserved. If a barrier can be established by that lease line well successfully and . maintained, then it would mean that operations on the Chakachatna acreage to the north would produce for that group only the oil under their lands and that operations to the south of that line by tbe SAS group would produce for them only the oil under their lands. Is that right? A Yes. Q In other words, it would afford protection of correlative rights at the same time it increases your total recovery. A Yes, it would. Q ....Now, in the rúle, we ask that the lease line well be permitted to be completed as a producer. Would you state'why it is necessary that this well be completed as a producing well, first. A Upon completion of the drilling, before the well is converted to in complete injection status, the flexibility for production is needed in order to provide a clean-up period of the well-bore, in that during drilling the pools under consideration 'for secondary will be invaded by some mud filtrate. There will. be some damage caused through the actual mechanics of the drilling, and a production period is necessary to clean up~ restore these pools to a condition as nearly as possible to their original. ¡ n,¡. mo-.I II :.....w... bv f)¡ V _ () fM R.r M n r 1 !;: '"'"',..",._ / Page 23 .~.. Q Well, then, really the only purpose for producing this well is to get it in condition so it can be used as an injection wel11 A 'Yes, sir. Q And, therefore, it should not be considered as a producing well under Rule 1 of the proposed order for the purposes of that rule as to either the Chakachatna acreage or the SAS acreage. A No, it should not. Q .....Now proceeding on to Rule 7, which provides for administrative approval of changes in pressure maintenance or secondary recovery operations. Perhaps before we go on to that Rule, we'd better get a little idea about how opera- tions might be commenced here, and if they prove successful, how they might be expanded and continued.....First, can you predict at this time exactly how they will go? (7'7'1) A Q Not precisely. Can you give us some general idea" assuming that everything goes just like you'd like it to go, what do you think might happen? A Following the injection of fluids into the lease line well and the completion of development to two wells per quarter section from the permanent platform, . the next step involved with the Chakachatna acreage would be probably to initiate the injection of fluids to the north extremety of our drillable limits from the Chakachatna Platform D. In essence, we would then be con- ducting an end-to-end water flood, producing the oil from the producing wells in between. This would be expanded depending upon the actual per- formance of the flood. Wells would be added to injection, taken from injection, as performance would dictate. Q Do you feel that Rule 7, which would in effect require the concurrence of all seven interested, working interest owners and of the Committee itself before any of these changes are undertaken, give sufficient protection to all interested parties? -~,.,-------- ------_._-- v ·,~·)rJ1- ._...\:: .' :~¡;_!:.~::~"::.::;~ I "~'"""'~ i, f~·~·" . . ,~ lY~?") A ~. Page 24 A Yes, it does. Q Would the rule, in your opinion, give a desirable flexibility in the opera- tions that will actually be needed if they are to be conducted properly? A Yes. Q Will it increase the efficiency of the operation ~o have this flexibiiity? A It will. Q Are you famili~ with the practice of other states with respect to the conducting of secondary recovery operations under Commission orders? A With some, yes. Q .....Is this a customary provision in other states? A It is. .....Let's just run through each of these permitted matters and give... the first one is that the Commission would, or the Comroittee could, permit the conversion to injection purposes of any well initially completed, either as a producer of oil or as a dry-hole. In your opinion, will such conver- sion be necessary in conducting a' secondary recovery operation? Yes ....As a matter of fact, isn't that probably how most of your injection wells will be selected? A Yes, quite so. Q ...."B" says that the Committee. may permit the drilling for injection purposes of a well or wells at any location. Is it possible that in addition to the lease line well, which will be drilled purely for injection purposes, other wells might be drilled purely for injection purposes? A Yes, this would be' based on the flood performance. Q Is there any way to predict at this t~e where those wells might be located or how many there might be? Q Q A No. Q ....Going on to "C", the Committee could permit the conversion from inject- tion purposes to producing status of any well or wells. Is it possible that t'hiA mia-hi" alAn bp- n~~~AAarv ar dêAirable in c.nnduc.t.inCl a sec.nndarv rec.overv Page 2S (3'14) A operation? A It is. Q .....Is this done occasionally? A On occasion....depending upon the specific conditions encountered, the type reservoir, type pool. This has been presented in several instances. Q In this particular reservoir, if you had to guess at this time, do you think it's very likely that ve~y many conversions from injection to pro- ducing status will take place? A It's quite possible. Q ....Number liD" says that the Committee may authorize the drilling of additional wells, that is wells not otherwise authorized by the field rules for producing purposes at any location. ....In your opinion, in order to conduct an efficient fluid injection secondary recovery operation here might it be necessary to drill additional wells, that is additional wells, a third well perhaps, on a quarter section that already has two wells on it? This is possible. Q And there again, if all seven companies and the Committee agree....should it be permitted as an administrative matter? A Yes, it should. Q ....The next item is that the Committee may permit the commingling in the ,-- 'c '.....-/' well bore of fluid produced by a well from any pool defined in Rule 2 with fluid produced by said well from any other poolsdefined in Rule 2. In other words, the Committee again assuming that all seven companies and the Committee itself agree, m ay permit commingling in a manner different from that not permitted....as an administrative matter. A Yes, this flexibility is desirable. Q .... I think you've' already pointed out that with reference to Pool "A" it might prove desirable in the future to commingle it with Pool liB" or some of the others. r---- A Yes. o Is that one of the situations that mi2ht arise? -. (;§?~) A Q Page 26 A It is. Q And "F" is a similar provision with respect to injected fluids on commingling. Is it also possible that you might want to commingle injected fluids in a different manner in a particular well? A It is. Q Now the sixth paragraph in our application says: Except as specifically set out in the field rules proposed by this application, operations within the area to be covered by the field rules should remain subject to the general rules of statewide application adopted by the Oil and Gas Conservation Committee. There are now in effect, Mr. Darsow, certain rules with respect to reporting of injected fluids and keeping records on a secondary recovery operation, and the Committee is considering the adoption of somewhat stmilar , rules in its new rules. Are you familiar with both the present rule and the proposed rules? Yes, I am. A Q ....Do you feel that except as set out in those, this application, those general rules will be sufficient to give the Committee sufficient information about the water flood operation being conducted? Yes. There is one point I want to cover before we leave this. We haven't discussed too much the area which will be developed by Platform "c" and perhaps by Platform "D". In your opinion, should the area which will be developed from Platform "c" be subject to the same rules as the area which will be developed or is being developed from Platform A and B? It should, yes. The same rule should apply with Platform C. Essentially you have the same pools, you have the same engineering problems, the same geological problems, and operations should be the same? A Q A Yes. I ....,~ -'--~" :-............... T"'\.;u ^.f'~¡f~. 1\¡f n-rl c:! _ .........._ I "- Page 27 '- Q Well, now, with respect to the area covered by Platform D. Should it also be subject to the same rules as the areas which will be developed by Platform /"~""". A, B, and C? A It should in that all four of these platforms are on the same general structure. The amount of data known in the vicinity of the Platform B, Chakachatna Platform B, or the SAS Platform C is limited. However, in that it is the same general structure, a continuation we feel, or I feel, that it should be included and treated with the same over-all field rules. Q A great deal of the information which has been obtained from platforms, the drilling of wells on Platforms A & B can be applied to the areas which will, be developed from Platform C and D, can it not? A Yes, it can. Q And, while if you didn't have Platforms A and B'and the development from them to guide you, it might be premature to enter an order on C and D. With that information it is now not premature? ' "-6' ~r if) A The data that we have obtained from the wells drilled from Platform B and A have of course added to our over-all structural interpretation and has strengthened us to the point that it is a very firm view that this is a continuing structure and that even though we have no specific well data from the two platforms to the south that they should apply to the same over~i all field rules. Q As development takes place on those, in those, two areas, that is C and D, if they are included in this order, will that permit secondary recovery operations to be initiated in those areas....as early as it reasonably could be? C:::? A Yes. Q And might that be a great advantage? .-/ A I believe it would. I Thle docu"*Il II ~ by Di v. of'M & M orIs from f'efralwm ,/'-.--"". (933) Page 28 Q If the area to be developed from Platform D should be included in the order, what would that area be? What would you propose? A 'I would propose that the area to be included would be the exact area included in the South Middle Ground Shoal Unit area which Q Would you read for the record the description of those lands?............ CHAIRMAN WILLIAMS: We might take a five minute break while he looks for the information. MR. SWAN: Are we ready to proceed again? CHAIRMAN WILLIAMS: We are proceeding again, Mr. Swan. Q A Mr. Darsow, what is the area which would be developed from Platform D. The area developed from Platform D would, as I mentioned earlier, include the lands within the Middle Ground Shoal Unit area which are: Township 7N, Range l3W, in Section 10, the north half and the southeast quarter; in Section 11, the northwest quarter; in Sect~on 1, the northwest quarter; all of Section 2, and all of Section 3·. Going to Township 8N, Range l3W; all of Section 35, thê west half of Section 36, all of Section 34. The South Middle Ground Shoal Unit area does include ,the south half and the north- east quarter of Section 27, a portion of which is within the area defined by our Exhibits I and 2. The east half of Section 27 is already in our area for which field rules are requested; therefore, with regard to Section 27, we need add only the southwest quarter. Now, with resp~t to the sufficiency of the general conservation rules as applied to this field, the Committee in its notice of the hearing, stated that they felt that we should also consider the adoption of field rules providing for minimum cementing and casing requirements, providing for gas- oil ratio surveys, and providing for bottom-hole pressure surveys....Ar~ the general rules with respect to these three topics sufficient, in your opinion, for this field? Or should special rules be adopted? Ii Q I n... -'-_...:......,¡,..,c Iw 1ìhT {"\f "~j ' RT ~j ' n-rh:;¡ '""" Jtetra/eum I <~ ~ (75t;') A Page 29 You mean general rules in existence? Now in existence. Either the general rules now in existence or the proposed rules. A No, I do not believe they are sufficient. Q You would then recommend that the Committee adopt a specific rule on each of these three subjects? A Q A Yes. Q As a part of these three rules? A I do. Q Let's take up the first one. The Committee has in general proposed .that with respect to cementing and casing that the minimum amounts to protect fresh waters and known oil and gas zones should be specified. For example, surface casing to 2,000 ft. with cement circulated and production casing with sufficient cement to cover the top of the "A" Zone. Firstt do you agree that a rule is necessary to accomplish essentially this purpose? I think some rule is in order, yes. Would you have a re.commendation to make, and if so, tell us what it is and why you would make it. In looking at the proposal, I would recommend that indeed the protection is necessary for the fresh water to shallow depths. I would recommend that the minimum surface casing requirement be 1,600 ft., and I would recommend in the cementing of the production casing, that a sufficient cement volume be used to cover the uppermost producible pool. ....If such a rule is adopted, in your opinion, will it adequately protect the fresh waters and your producible pools. It would. The 1,600 ft. of surface casing would be sufficient for isolation of the shallow water-bearing zones. It would be sufficient to provide adequate strength for setting longer casing strings and would also provide a sufficient strength for your blowout preventer assembly. A Q Q A I nolo ~ .. ~ bv lìi v _ ()f"M R,. M nr 1 ~ '""" "'!nII"," I -~ Page jO Q Is it possible that some variance from this rule might be desirable in specific wells? A ·This is possible, yes. Q ...Do you think it would be well to include in the order a provision that, some't.¡hat similar to that in proposed Rule No.7, that would permit variances as an administrative matter if all affected parties, that is, the seven companies and the Committee itself felt that a variance was justified? A Yes. Q In other words, there would be no need for a hearing on the point if every- body affected agreed that the variance was proper? A That is correct. Q Now with respect to the gas-oil ratio survey. The committee proposed an annual gas-oil ratio survey on all producing wells should be made. And states that these tests are necessary to obtain information on reservoir .'"....~.. withdrawals and utilization of reservoir energy. Do you agree that such a survey is necessary? ( 7Y/) A I would agree with the survey and the proposal as submitted by the ~o~ittee. Q In other words, you feel that it would be proper for these rules to require an annual gas-oil ratio survey on all producing wells? A This would be proper. Q As a matter of fact, is such information being currently obtained by both the operators for both groups? A Yes, it is. Q And this then would not impose any additional burden on them or require them to do anything that they are not doing at the present time? A No, it would not. ~, Q Proceeding ön to your bottom hole pressure'surveys.....They propose a ""---,./' semi-annual bottom hole pressure survey on all wells with a 24-hour shut- in build-up, with the first survey to start in September of 1967. First, do you agree that bottom hole pressure surveys should be made in this field? I ....._ ...L..-_. .. :..-.'-<1.... n; u r>.f '~1f R. 1\1f 1"1"'- 1 Q ....... -......_ I ~ --- Page 31 A Yes, they should. Q Do you agree with the proposal of the Committee. or would you suggest an ....--.., alternative? A I would prefer to suggest an alternative in the case of the pressures. Form two standpoints, first the type reservoir we have, I believe that a semi-annual coverage would not be necessary. The....just the overall program that we have under way in the Middle Ground Shoal Field the more we can obtain our necessary reservoir control but still minimize our down time. This is very important to us. I'would therefore propose that rather than a semi-annual survey that we would have a rule for annual survey; not of all wells, but of select key wells. The key wells to be determined by the two groups and the Committee. I would further recommend that the rule on the obtaining of bottom hole pressures not be limited to a 24-hour shut-in, (/Oð C ) l, _"",-,"1' but be modified to" include any methods that can obtain acceptable pressures. By that I mean either a shut-in survey, static survey, or the obtaining of ~~..~ multiple flow rate tests. Q Do you feel that anyone of these three methods might prove satisfactory for this-field? A Yes, theywouldo Q Well if I understand your proposal then, basically it is that there should be a firm requirement for an annual bottom hole pressure survey, but that it should contain sufficient flexibility so that prior to the time each survey is conducted the seven affected operators and the Committee can agree upon not only the wells in which it shall be conducted but the manner in which it shall be conducted. A Yes. Ii Q Is there any way at this time in view of the undertainty of how the water flood or other fluid injection m~ght proceed, to specify the wells or to determine the best method. A No, the number of key wells cannot be ·£ixèd in. that development will con- I Th_~IIt~by nïv. of'fvy &- Mnrls '-'-'""_ Page 32 tinue and perfo~ance of the secondary project ~l váry the selection of the key wells from time to time. Q So, in effect, the decision should be made each yèar as to just how to conduct the survey and up on what wells. A This would be satisfactory. Q As a matter of fact, won't it be necessary to do it that way? A Yes. Q There is one point that we may have over10~ked, Mr. Darsow; under proposed Rule 7 you said that it might be necessary to convert wells from injection purposes to producing status, and might also, would also be necessary to convert them from producing status to inje~tion status. As a matter of fact, is it sometimes possible that you could, might, convert them back and forth. By that I mean a well which was a producer might be used for injec~ tion purposes for a period of time and then converted back to a producer, and maybe even conv'erted back again to injection purposes. A Yes, we refer to this as a pressure pulsing technique. It has been utilized in other oil reservoirs. At this time I don't know if it would be successful in the Middle Ground Shoal Field, but it would very possibly be considered. Q It is important that if it is desirable to try it that these rules permit that it be done? A Yes. Q And Rule 7 would permit that this be done? A It would. Q I think we are about ready ,to conclude, Mr. Darsow. Have we left anything out on these exhibits that you forgot to comment 'on? A Not to my knowledge. Q Were they prepared by you or under your supervision? A They were. MR. SWAN: I would like to offer at this time exhibits. applicant's Exhibits One, Two, Three. Four and Five. CHAIRMAN WILLIAMS: We will accept Exhibits 1. 2. 3. 4. and S into the record. '~- Page 33 MR. SWAN: This concludes Pan American's presentation. As I've said, we have tried to eliminate some detail that was contained in previous hearings, but you won't hurt our feelings if you go into them now. CHAIRMAN WILLIAMS: Are there any quest ions on the technical aspec ts of the~i exhibits or testimony? (From Background) Mr. Swan, I count six exhibits up there. Did you ,leave one out? MR. SWAN: That's Shell's exhibit. (From Background) I see. c:::7 MR. SWAN: We have...this is a joint application and it's a joint presentation, but I think they have put their exhibit on there. CHAIRMAN WIIJ..IAMS: Mr. Marshall. MR. MARSHALL: Mr. Darsow, I have a question of a general nature. When would you commence your injection of fluid? By this questioq, I mean, at what state of the reservoir, under what reservoir conditions are you waiting for to commence your injection? MR. DARSOW: Right now, with the circumstances as they now are, we would, with the Commission's approval of our application, proceed to drill a lease line well and initiate our fluids into that well as soon as we could possibly clean the well up and obtain our injection equipment. As far as the reservoir standpoint is concerned and the performance that we have measured to date, depending upon the specific pool we're talking about, some of the reservoir could be slightly below bubble point at the ttme injections commence. Other portions of the reservoir could be slightly above bubble point. It would be our intention to initiate as rapidly as we can this pressure maintenance to try to arrest any pressure decline and build any decline back up to where we could maintain reservoir pressure above the bubble point. I TN.~'" ~ by Div. afM & Mnrls ffom MvI_ I '-' '~ Page 34 MR. MARSHALL: I see, then this would determine the amount of fluid you,would withdraw from a given injection well or well drilled for injection purposes before you use it for, pardon me, would this limit the amount of production from a particular well and determine when you would use it for injection purposes? MR. DARSOW: Because of the nature of our operation, no it wouldn't limit our amount of production from any producer, but to combate or to offset our amount of production would simply increase and expand our secondary project to include enough injectors to where we could inject enough volume to where we would attempt a positive injection or reservoir withdrawal balance. We can't say specifically at this time in that we haven't conducted our injectivity tests. It may turn out that we can inject enough fluid where our number of injection wells would be small. On the other hand, it could turn out where a large number are required, but you realize the nature of our structure and the narrow width we would have to proceed with the development, conversion to wells as they would be avail~ble for this purpose. MR. MARSHALL: Thank you. MR. GILBRETH: Mr. Darsow, in line with Mr. Marshall's question, what kind of a time lag are you really looking at, do you think at this stage, to maintain your pressure? Are you thinking in terms of a year, two or three years, or do you have any idea? MR. DARSOW: Well, I can only comment with respect to the Chakachatna acreage. With the successful completion of the lease-line well in finding that injection, would be successful, the amount of acreage that we have available to develop on a two-well per quarter section basis, I would estimate that we would commence injection~ in early, probably in 1968; but that 'the expansion, because of platform space, platform operations could not take place before development was complete. In the case of our acreag~ the development should be, complete approximately the end of 1968 following completion of development where we would be relieved of our space limitations. We could then go to the necessary injection equipment for a expansion. I Thie -.-" II ~ by Di v. of'M & MarIs from"'~ I - Page 35 - MR. GILBRETH: Referring to your Exhibit 3 and 4, you show considerable area ~'-'~""'--o-, there developed under the existing spacing pattern. Have you at this time picked the location where the proposed lease-line well will be7 Could you show us on either one of those exhibits about where it would fall. MR. DARSOW: In reference to these exhibits, it would fall 1,200 feet east of my section line. This represents here a half mile, 2600. It could fall about right in the middle. I do not have the cross section exactly on the lease line but my cross section BB prime" Exhibit 4, would most nearly represent this condi- tion. As a result, our lease line well as proposed would in essence, to the best of our knowledge of the wells drilled, penetrate the entire productive area. MR. GILBRETH: It would fall then somewhere between the upper and lower limits, somewhere mid-way of what you show on the exhibits7 MR. DARSOW: Yes, it would be on what we could term the east flank of our reservoir. It would not be on the crest. MR. GILBRETH: Well now, if this well is drilled early or soon, I believe you stated that you do not know at this stage even what your pattern will be or what your wells will take. Is it likely that this well will be a badly spaced'well for subsequent use in a pressure maintenance program7 MR. DARSOW: No, to the contrary, in our meetings that Pan American has had with Shell, we feel that the selection of...we looked on a planed view...selection well 12, 1200 feet east of the quarter section line would be a good, very good location for an injection well, particularly when we consider the amount of exposed penetrated section encountered with a deviated drilling program. The fact that platform drilling has caused the wells to have a trace of collective limits over such an extensive area. We find that this would be an ideal position to benefit both groups. MR. GILBRETH: With reg~rd.;~to~your proposal for rules on ~cement~. I believe you mentioned that you would recommend that sufficient cement be used to cover the ¡ n... """-. .. :......w.... Iw 1ìi v. () fM ~ M n r] ~ fforn '-'""-" I ~' Page 36 uppermost produceablc pools. Would you give us an idea how this might be defined to put into an order? MR. DA1\SÙ\Ýt HC!ll. by your [)\~OduCêêblê pool, At tbe time of coursc of cOIn@nting. the main tool, or the only tool we have to go on is our log. And it would depend upon the log analysis. The point being that we proceed from north to south on the Middle Ground Shoal structure. We find that it plunges, that anyone pool that we are talking about becomes wet, if you will, to the south. As a result, the farther south you go the only producing horizons we encounter will most likely be the fools E, F, and G. For this reason, by defining it as produceable we would then have the field rule requiring cement into cover the zones in that specific area without causing a necessity to cement higher where there would serve no purpose. MR. GILBRETH: I see. You feel then that it wouldn't be necessary to cover the other zones even though they are productive farthe~ up in the pool? MR. DARSOW: No. I think that the definition of produceable this would give us the sufficient protection we would need, and as we are away from our produceable areas that it would not be necessary to cement all these zones. MR. MARSHALL: Mr. Dar sow , in relevance to the discussion of the Platform "D" area, the so-called SMGS Unit, do you have any reason to believe that there are any geological discontinuities or other permeability barriers which may give rise to different reservoir conditions which might or might not be applicable to the case at hand? MR. DARSOW: We are not sur~of course, in that we haven't developed the entire area where these geological changes or permeability barriers or faults may occur. As it was pointed out in the formation of the South Middle Ground Shoal Ii unit, we do believe that something happens geologically between the SAF Platforms "D" and the Chakac1;1atna ~latform "D", specifically where, we do not know. From the data of the one well we drilled in the Soutb Middle Ground Shoal area' and~ I n... .w._. .. :"".&r.of Iw ni '\1 () fÍVT ~ M n,..l ~ 'tOm MaI_ I Page 37 - '''-' tested, we find that the E.

DARSOW: I'll back up a little. I don't know how much we've missed. I feel that the data that we have obtained from the exploratory wells drilled in the vicinity of our Chakachatna Platform "D" has provided sufficient information . to indicate that the type oil accumulation in the "G" Pool is' similar. The inclusion of this area in the same gen~ral field rules. I think, would provide the flexibility that would indeed be useful in developing this area; and, at this time, whether a complete development of two wells per quarter section would be undertaken, we couldn't say. This would depend on the actual development as . it takes place. MR. MARSHALL: Thank you. CHAIRMAN WILLIAMS: Are there any other ..... Mr. Whalen, please? Mr . VonderAhe. MR. VONDERAHE: Mr. Darsow, you had said that the primary recovery estimate was 15 to 20 percent oil in place on the primary. secondary 25 to 30 percent. Is that based on the assumption that there would be SO-acre spacing? MR. DARSOW: Yes, in that I feel this way; that the tight structure we have underlying our leases in particular. we are so narrow and so steep that a secondary project is almost impossible to conduct under this wide a spacing, particulari~y in that all our wells are located right on the crest of the structure. MR. VONDERAHE: Thank you. CHAIRMAN WILLIAMS: Mr. Wallington? No questions? I have one then. In your application, Mr. Darsow. in suggested field rules; Rule 1. sub-rule A, I may have missed this somehow or other; we got ,past this before I realized it. You state that oil wells may be completed closer than 1000 ft. to any well drilling to, or capable of producing from the same pool. Nowhere is there I ........ ~_... :-.......... l);u I"\f ·~IT RT ~IT n,...l ~ "-'.......,_ I "- ~. Page 38 then a mintmum distance between wells suggested. Do you think that there should be a minimum distance set forth7 ~m. DARSOW: No, sir. That particular part of the rule is simply a re- statement of the field rules as granted by Order No. 31. The previous testimony of the previous hearings requested the removal of the 1000 ft. minimum, and we simply, in the preparation of this application, listed the field rules in existence in addition to the new field rules requested. CHAIRMAN WILLIAMS: Yes, but I am asking now, do you think there should be a minimum distance? MR. DARSOW: No, I do not. Again, referring to my cross section of exhibits, the width, the narrow productive limits that we have involved combined with the drilling problems associated with deviated drilling, I think we should leave the existing rule in effect, not requiring a minimum for these pools so that the operator has the flexibility to, in this instance here, to penetrate the upper pools within their productive area and then through well bore control position the TD at the selected location. CHAIRMAN WILLIAMS: Thank you. I believe that.....you can sit now. Thanks very much. I'd like to, direct a question to Mr. Swan. In your request for an order, you are requesting an order which would provide for drilling of extra wells, changing of commingling, and changes in secondary recovery, all to be determined by administrative procuedures rather than a hearing. In the regulations under which we are presently still having to operate for a little while yet, we seem to have three different sections that prohibit this. I'd like your comments on the legality of doing these things by administrative decisions. MR. SWAN: I think you could do it by administrative decision if you, after notice and hearing, adopt the specific order applicable to a specific field that provides for it. I don't th~ there's anything in the.....in fact I would.... perhaps I ought to put it this way; I would challenge the statement that there's ,",,1a~_'''''_~'- T"\hT nf :~Ir RT ~Ir n-rl ~ '""" "'InII_ I .~= '- .,.-;/ Page 39 anything in your rules or the law which prohibi'ts this. If there's something in the rule, then I say that the rule is taking away the right that you have under the law, and that the rule is invalid. CHAIRMAN WILLIAMS: Well, in commingling for exampl~. You are requesting a possible later administrative decision that you would be allowed to commingle pools which are at present prohibited, and our Section 2157 says "commingling of production from two or more pools in the same well bores will not be permitted except after notice, hearing, and a special order of the Committee,1I etcetra. This is what bothers me. MR. SWAN: Here again, it's the general rule. You've already varied that in the field rules you now have, and you have had your....this is the hearing today which gives the basis for this, and again·I say that if all of the affected parties, and they're here today, feel that this flexibility is necessary and desirable, and if all of the affected parties in the future agree that it should be done, nobody's rights have been impaired. Now, as I pointed out, the Committee has a veto power. If at any time you think that a hearing is necessary on any of these items, all you have to do is say, "we want a hearingll. CHAIRMAN WILLIAMS: I have no argument with the desirability or the need for flexibility in this matter; I just wanted to be sure that we can legally do this. MR. SWAN: I get back to this. I think the law permits it. If the rule then tries to take away a right that the law has given me, the rule's invalid. CHAIRMAN WILLIAMS: Are there any further questions from the Pan American people? I guess then that the Shell Oil Company people would like to make a presentation. ~. RUDD: Mr. Chairman, prior to introducing our witness, I would just add to this question you raised with Mr. Swan concerning the legality of an order such as requested by the application. I Thls~' II ~Irwd by DiVA of'M & M nr 1 S from "lY'oIeum I o~ Page 40 CHAIRMAN WILLIAMS: This is Mr. Rudd speaking, I presume'l MR. RUDD: It is, and I agree thoroughly with Mr. Swan, that we are having a hearing now at which the subject is being discussed and information is being placed in the record regarding the pools, and I see no reason why a separate hear- ing has to be called for a particular request for a variation of the permissable commingling. And likewise on the other aspect of the administrative approval that has been requested in the application; lid simply like to second Mr. Swan's, view on that subject. CHAIRMAN WILLIAMS: Thank you. MR. RUDD: As to our presentation, Mr. Darsow has ably presented a great deal of the basic information concerning this applicatiori,and we do have a witness who has not, I believe, appeared before the Committee before. We'd like to qualify, v enter an exhibit, and make a statement, and then throw it open for questions if you may have them. Our witness is George Cook. MR. COOK: My name is George Cook, a resident of Anchorage, employed by Shell Oil Company, Production Division, as a staff production geologist. Graduated from the University of Toronto in Canada in 1952 and been employed for the past fifteen years by Shell Oil at assignments initially in the Benton Field in Illinois; and from there I went to Canada and worked in Mydell Field in southern Alberta fields of Waterton, Rainbow, DeDouc, Woodbend and many others. Came to Alaska tbe past while at which time I have undertaken the study of the Middle Ground Shoal Field in a geological basis. MR. RUDD: He has the qualifications to be accepted. CHAIRMAN WILLIAMS: The qualifications are accepted. MR. RUDD: Mr. Cook, on the wall behind you here there is an exhibit. Was this exhibit prepared by yourself'l MR. COOK: Yes sir. I ~._ ~____. ~ :....-..L__a.. T"\iu ^.f '~IT ~~ \11'".,...1 co '- ........__ I Page 41 ""-' MR. RUDD: We have not marked it as an exhibit, principally because I didn't know whether the Committee would like it marked with a letter or a number. Make it Exhibit 6 or Exhibit A. CHAIRMAN WILLIAMS: We will mark it Exhibit 6. MR. RUDD: Alright. Perhaps, Mr. Cook, you could go up to the exhibit and simply describe it briefly and then return for making your statement there. MR. COOK: I have prepared a cross section. Mr. Darsow has pointed to it previously. The cross section CC which is centered on the SAS group Platform "A", and we're using this section primarily to show how we've established the western and eastern limits of the field. The section is taken through the· west fault zone, penetrated by the A-23-l2, or east flank of A-23-l2 Well, and the west fault zone, 32-11 Well. Referring to the cross section, we have colored the upper B, C, & D Pools and the lower E, F, " G Pools. We haven't colored the "A" Pool, although it has been found hydrocarbon bearing by logs in several SAS wells. We haven't yet ","--' tested it. You will notice the location of the section on the south plunge of the "",- MGS structure. shows the upper B, C, & D Pools plunging off ,and thinning out to the south over the SAS property. As such, it is the minor pool on the SAS property and my remarks will be confined mainly to the lower pools which are the E, P, & G Pools. MR. RUDD: I thank you. And you have prepared a statement to the Committee? MR. COOK: Yes, I have. The following remarks pertain to that part of the Middle Ground Shoal Field concerning the SAS leases. I basically agree with the statements and exhibits of the Chakachatna group. Over the SAS properties, lease ADL 18754 and ADL18756, the productive l~its of the Middle Ground Shoal Field have been defined by the drilling of wells and associated seismic data. Every govermnental quarter section which can be developed from the SAS Platform "A" 3\ has now been drilled, and it is now apparent t~at wells drilled under Conservation Order #31 will not recover all of the oil which can economically and efficiently be ,.... recovered by primary or secondary means. Accordingly, in areas of the field where I ...... ........_. .. :"""-1 h. r\hr f'\f '}.) ' R. XII' n,..l Q ftøm "''''''...... I , ~ ~ Page 42. adequate thickness of the commingled pools can be expected, an additional well per quarter section should be permitted. Our preliminary investigation of the reservoir parameters has encouraged us to believe that additional oil may be recovered from the Middle Ground Shoal Field by ~he injection of water to supp1e- ment the expansion-type primary recovery mechanism. Although primary development on the SAS properties is not nearly complete, we are requesting permission to inject water at this time because we believe there is an economic advantage to injection at as high a reservoir pressure as possible. Before committing to a full scale injection program, Shell first proposes to conduct an injectivity test at a selected SAS well. This test will allow us, to determine if water can be injected at reasonable rates and pressures, and more important. that a full scale flood is feasible. The interpretation of drilling and seismic data at Middle Ground Shoal has delineated a long-narrow up-thrust accumulation of hydrocarbons. The oil is contained in a thick series of poorly sorted.sands and conglomorate. Below the "A" Pool, the overall stratigraphic interval is 2400 feet thick and . is produced from two segregated zones containing three pools each, B, C, D, & E, F, G Pools. I'll refer you once again to Exhibits 3, 4, & 6 for design~tion of pools. We have found that the structural complexity is not great. Other than the bounding west flank fault zone, no disruption of lateral reservoir continuity on SAS lands has been found to date. Minor faulting was encountered in the lower zone at wells A-ll-l and A-13-l and in both cases we believe the faults are a part of the west flank fault zone. Control for positioning the west flank fault zone is obtained by;:~ying ,in the safe seismic data with the Chakachatna No. 8 well and the SAS A-32-l1 well. The east flank limits have been penetrated by two SAS \o1el]s, A-23-l2 and A-33".1.. I might just point those locations out. For obtaining our east flank control from the A·33-1 and the A-23-12 well, both ? ? wells indicate east flank ltmits through either water production or tight safety. I nolo _I .. :......w... bY 1ìi v _ ()f'tvr Rr M n r] ~ from MoIeum ~.. Page 43 Our west flank Itmits have been tied in by the Chakachatna No. 8 well and the SAS #32-11 well. Upon this data we have simply projected our verified seismic data to the south and this is how we....down over the platform "c" area, SAS group. Within the ltmits of this projected seismic data, we have no reason to believe that the boundries of the undrilled southern part of the field will vary appreciably from that shown on the Chakachatna structure map exhibits. To demon- strate the ltmits of the reservoir in the vicinity of the platform "Aft, as mentioned previously, we have prepared structural cross section CC. The lower zone accumula- tion is located in a poorly sorted silky conglomorate, a mixture of quartz chert and quartzite class, varying from pebble to rock size make up from 30 to 60 per~ cent of the reservoir rock. Average porosity varies from 8 to 15 percent. Net pay values as high as 527 feet have been found. We have been able to carry a correalation of eight layers in the lower zone and thus study sand continuity over the length of the field. From this we have concluded ~hat there is no serious amount of san~ lenticularity, rather in the lower zone we visualize that the C--7 '--". individual sand layers are blanket-like. Although there is a reduction in net sand development over a large part of the SAS portion of the east flank of the field, we believe that there is still sufficient sand development to sustain the lateral continuity of the reservoir. The remaining remarks will be on the suggested field rules. Bottom Hole Pressure Surveys. Shell presently obtains a shut-in static bottom hole pressure on each new completion. In addition, we have obtained conventional pressure build-up data and have calculated shut-in bottom hole formation pressure for multiple rate flow tests. On the whole, we have found that the results from the multiple rate flow tests ~gree quite well with the conventional pressure build-up tests. Accordingly, we would recommend that the field rules contain sufficient flexibility to allow collection of pressure data in the form of multiple rate flow tests, conventional build-up, or 24-hour static pressures. ThIA ~t IA ~ bv niv _ ()f"M Rr M nrl F: ftom MoI_ I Page 44 We would also be in favor of an annual field-wide pressure survey on selected key wells. Gas Oil Ratio Surveys. Shell's practice is to run a gauge test on each well at least once per month, at which time the gas rate is also obtained. Consequent results have been reported to the state on an individual well report. In our view, further testing and reporting is unnecessary. Rather, we visualize the state's selecting data from one of these tests to fulfill any further requirements. Cementing and Casing. Shell's standard practice for surface casing depth is 10 percent of the total anticipated open hole. Minimum, 500 feet. For the Middle Ground Shoal Field a minimum surface casing depth of 1600 feet cemented to tbe R\ surface is recommended. This would provide adéquate protection from the contamina- tion of shallow sands, anchoring of blow-out preventer equipment and support to deeper. casing strings. This depth would also allow 855 psi back pressure at the surface when drilling ahead with salt water or '710 psi. using 80 pounds per cubic "--~" foot mud; that which is the heaviest to date in Middle Ground Shoal Platform "A". <::J For other casing strings, a minimum of 500 feet of cement or 500 feet above the uppermost produceable zone in that well is recommended. Thank you. CHAIRMAN WILLIAMS: Any questions? Mr. Marshall? Mr. VónderAhe? Mr. Wallington? Mr. Gilbreth? No questions. MR. ROOD: Mr. Chairman, may I ask that Exhibit 6, which we will mark 'as such, be admitted? CHAIRMAN WILLIAMS: Exhibit 6 will be admitted in the record. MR. SWAN: Before you close the hearing, could I amplify a little bit my previous remark on the Rule 2157, particularly? CHAIRMAN WILLIAMS: Yes, Mr. Swan. MR. SWAN: I am not contending that that rule is inv~lidì actually I think it is valid. What I'm saying is that today we are having the hearing which this ¡ nolo ~I 10 ;"""1nId bv n; V _ () f'M &- M n r] s from...IroIeum I Page 45 rule requires, and if you enter an order as payed for in our applicationJ you will establish in that order the conditions under which commingling will be permitted and those conditions afford adequate protection to all interested parties. So today is the hearing that this rule requires. What I'm saying is that if you put an interpretation on that rule which in effect says this i8n~'t the kind of hearing that the rule is talking about then you have made the rule invalid, and when you have two possible interpretations, .and I don't admit that that second interpreta- tion is possible; but if you think it is, if you have two possible interpretations, one of which renders it valid and one of ' which renders it invalid, you should take the interpretation that makes the rule valid, and we feel that the conditions under which commingling would be permitted under our proposed rule are certainly adequate to protect all parties, including the state itself; and we feel the same with respect to the other rules where this question might arise. Today is the hearing that is required for the doing of any of these' things a~d that the standards in the proposed order would adequately protect all parties. And of course I point out again, if all parties don't agree, there has to be a hearing. Whether that means all of the companies have to agree that are affected and the state itself has to agree. CHAIRMAN WILLIAMS: Thank you ....................We'll pause and consult here a moment if you please. (approximate three minute pause) Mr. Marshall has a question, I believe, for Mr. Swan. MR. SWAN: Yes sir. MR. MARSHALL: Mr. Swan, concerning Rule 7 t Administrative Approval of Changes in Pressure Maintenance in Secondary Recovery Operations; you would be actually giving us a written formal request for any such change that you contemplate. Is this correct? MR. SWAN: Yes, and it would be a joint request by both Pan American representing the Chakachatna group and Shell representing the SAS group on any of these. Ii, I ...... ......._. .. :""'.a-t hv 1ìi '\1 f"If'M RT 1\¡f n,..l ~ from PwtroI~ I Page 46 MR. MARSHALL: Now, in this conservation order that we will be writing concerning the matter at hearing today, we go along witb tbe administrative approval aspect. Then I'm trying to think abead of how we can make, let's say, availability to the public of this administrative change. If we would not be going through the courts, publication.and writing another order, then we would possibly place your request in the conservation file whicb is open ~o tbe public at all times. The reason I bring this up is the confidential nature of some of the " applications you may make. This would be in a public file and I just wanted to have that point straightened out with you; that any application you would make under this, we would consider would be of a public nature. MR. SWAN: I'm shooting a little bit from the hip bere, but I can't imagine anything that we would file under here that should be treated as confidential. It C::] seems to me that, frankly, in order to protect the public in this case it should go in the file, and it should be a matter of public record. This is somewhat like.... -----."... we don't have' notice in hearing when we file an application for permit to drill a well, but it certainly:'. becomes public knowledge that we are going to drill that well, and I think they would have to go in a file where the public could see. MR. MARSHALL: Right. And of course in the case of a well, we have administra- tive mechanism up where we attempt to give tbe wbole world constructive notice of that particular location. This is something that as far as administrative approval to this Conservation Order ~wbich is yet to be written, we would probably distribute copies of any administrative approval we may make to a mailing list to people who are interested in conservation orders and other public notices. I just wanted to bring this point out. MR. SWAN: We haven't got anything to hide on any of the things that would be filed under this, and it is quite a bit different from some of the other tbings tbat we are required to file. CHAIRMAN WILLIAMS: Notbing further tben I guess. The meeting stands adjourned. The hearing, I should say, stands adjourned. ,i 1> OF HEARING ! n.... .-._, .. :""'1rM Iw T); V () f .

Basically we would advocate the general require- ments I isted below but would consider other alteraative~. Detai Is on survey dates, depths, reporting, etc., depend on basic requirements: I. Cementing and Casing - The minimum amounts to protect fresh waters and known oil and gas zones should be specified. For example, surface cašHng to 2000' with cement circulated and production casing with sufficient cement to cover the top of the A zone. 2. Gas-Oil Ratio Survey - An annual GOR survey on al I producing wel Is should be made. The ratio tests are necessary to obtain information on reservoir withdrawals and utilization of reservoir energy. 3. Bottom Hole Pressure Survey - A semi-annual BHP survey on al I wel Is with 24 hour C.I. pui Id-up. First survey should start in September, 1967. Discussion: Since these are large undersaturated reservoirs operating by fluid expansion, pressures wi II drop rapidly. Surveys should þe taken to show pressure performance so that the time when saturation pressure is or wi I I be reached can be forecast. Pressure maintenance should be initiated and pressures maintained near the saturation pressure for maximum recovery. Also pressure information in necessary to better determine the drive and efficiency. After saturation is reached, the surveys can be lengthened to less frequent intervals. On the wide spacing prevalent, pressures should be obtained on every wel I. If enough coverage could be obtained, an annual survey "- ~ on al I wells and a key wel I survey at the six month interval between ann~al surveys might suffice. Our main concern now is performance to the saturation pressure. No pressure data have been presented at the prior hearings and our fi les do not contain anything except an initial pressure. We are completely in the dark on performance after prod. of 5 mil lion barrels unless the forthcoming hearing reveá~s something. At this stage, there is no way for us to determine if waste is occuring or is eminent and unless pressure information is ob*ained, there never wil I be, hence the need for pressure information. ,,~',.- ".~'".;.; '"--~-'-' -~.- .-....~.¡,.~_._-,.~ (AdO.:) t t~;9 ..~ '\ o-.......~_~...:~~~_--'.--"___ \tÔ~~~J ~.__'~"" ..v"·' MGS RULE PROPOSALS To prevent contamination of fresh ~ater zones and prevent waste in oil and gas zones, It Is felt necessary to adopt rules providing for minimum cement- Ing and casing requirements and require regular gas-oil ratio surveys and bottom hole pressure surveys.

The area for which the Applicants request the establishment of Field Rules includes all of the area now subject to Conservation Order No. 31 and additional lands underlain by the same pools defined in Conservation Order No. 31, and said area is described as follows: T8N-RI3W, S øM. Section 22: SE/4 Section 23: All Section 24: W /2 Section 25: W /2 Section 26: All Section 27: E/2 Section 1: All Section 2: E/2 Section 11: SW /4, E/2 Section 12: SW /4, N/2 Section 13: W/2 Section 14: All T9N -RI2W, S oM. Section 19: S/2 Section 30: All Section 31: All T9N-RI3W, S.M. Section 25: E/2 Section 36: E/2 '~ y Applicants, and those companies on whose behalf this Application is filed, are the owners of all leases within said area, and the only parties other than the State of Alaska as Lessor of said leases who will be affected by the Committee I s Order herein. Said owners are now exchanging well and reservoir information; conducting studies of reservoir performance; and planning future development of the pools for the purpose of securing the maximum ultimate recovery from said pools through both primary production methods and the use of any feasible pressure maintenance or secondary or other supplemental recovery methods. 11,. There is now available new and additional evidence which will demonstrate that: The probable productive limits of the pools designated by Conservation Order No. 31 within the area subject to said order have been more fully defined by the actual drilling of wells; wells have been drilled upon almost every governmental quarter section or lot corresponding thereto within said probable productive limits; the wells which have been drilled, and may be drilled within the productive limits of the pools in com- pliance with Conservation Order No. 31 will not recover all of the oil from the pools designated by Conservation Order No. 31 which can economically and efficiently be recovered therefrom under primary or any feasible pressure maintenance, or secondary or other recovery methods; Conservation Order No. 31 should be superseded at this time by Field Rules applicable to the above described area, prescribing a spacing pattern for said area which will permit development of that part of the Middle Ground Shoal Field to be covered by said Field Rules to proceed efficiently and without delay and in the manner best calculated to accomplish the purposes of the Oil and Gas Conservation Statutes of the State of Alaska. III. That Field Rules for the above described area should be adopted and prescribed to read as follows: Rule I, Spacing Pattern. (a) Oil wells may be completed closer than 500 feet to the section lines or quarter section lines and may be completed closer than 1000 feet to any well drilling to or capable of producing from the same pool, except that no oil well shall be completed at a distance of less than 500 feet from a lease line where ownership changes. (b) No more than two oil completions shall be allowed in any governmental quarter section or governmental lot corresponding thereto i!l any pool as designated in Rule 2. - 2 - ".' ~. \..-,/ Rille 2, Pool Designation ø The vertical producing intervals shall be divided into seven (7) pools which will be correlated with the following intervals in the Pan American Petroleum Corporation State 17595 #4 Well. MGS Oil Pool A - 5300' to 5720' MGS Oil Pool B - 5720' to 6100' MGS Oil Pool C - 6100' to 6400' MGS Oil Pool D - 6400' to 6750' MGS Oil Pool E - 6750' to 7050' MGS Oil Pool F - 7050' to 7375' M GS 0 il Pool G - 73 75' to 9215' Rule 3 I Permissible Commingling. A well may be completed in and produced simultaneously from anyone or more I or from all of the above seven pools provided that the production from the pools is adequately segregated in the well bore and produced at the surface so that the following requirements may be met: (a) Production from MGS Oil Pool A I as defined in Rule 2 I must be segregated in the same well bore from pro- duction originating from any other pool. (b) Production from MGS Oil Pools B I C I and D I as defined in Rule 2 I may be commingled in the same well bore I but must be segregated from production from any other pool. (c) Production from MGS Oil Pools E,F, and G I as defined in Rule 2, may be commingled in the same well bore, but must be segregated from production from any other pool. Rule 4, Effect of Prior Orders. )(, A well which has been or is being drilled and completed on or 6 prior to the adoption of these Field Rules, and which has been or is being drilled and completed in accordance with any prior rule, regulation or special Order of the Committee may be drilled to com- pletion I completed I and produced in compliance with the terms of said rule I regulation or Order, notwithstanding the fact that such rule, regulation or Order may have expired or have been terminated or superseded, until such time as the Committee shall, after notice and hearing I enter an Order establishing different requirements or provisions applicable to said well. IV. That development of that part of the Middle Ground Shoal Field to be covered by these proposed Field Rules has reached a stage at which there should be included in the Field Rules provisions which will authorize the conducting of tests for the purpose of determining the feasibility of pressure maintenance or secondary recovery operations by fl uid injection, and the initiation of pressure maintenance or secondary recovery operations in said - 3 - . . . . ~ \..,./ area and a continuation and expansion of such operations if they are found to be feasible. In support of their ApplicatiQn for an Order adopting Field Rules authorizing such testing and pressure maintenance or secondary recov- ery operations, and providing for the regulation thereof, the Applicants show as follows: (a) There is attached hereto as Exhibit "A II a plat showing: the leases and lands which will be included within and affected by the proposed project (which are also the lands for which Field Rules are requested); the approximate location of the proposed joint injection well; the location of all oil and gas wells, including aban- doned and drilling wells, and dry holes within the proposed project; and the names of all operators of leases offsetting the area encom- pas sed within the project. (b) Exhibit "B" shows, as to each of the producing wells with- in the proposed area, the pool or pools as defined in Rule 2 in which said well is completed. (c) The pools to be affected by the proposed injection project are the pools defined in Rille 2. (d) It is proposed that there be drilled by Pan American as Operator for all affected parties from a surface location on the Chaka- chatna platform a joint well which will be directionally drilled to and completed at a location as nearly as practicable on the towns hip line between Township 8 North and Township 9 North. Applicants request that a special provision be included in the Field Rules which will permit the drilling of said well and permit it to be completed and pro- duced as an oil well in all or any of the pools defined in Rule 2 until such time as injection can and should be commenced and further, permitting its conversion to an injection well, provided however, that said joint well shall not be considered as one of the two wells permitted to a quarter section by Rille I, as to either Lease ADL 17595 or Lease ADL 18754. (e) Exhibit "C". attached hereto describes a proposed casing program and the propÖsed method for testing casing before the use of any well as an injection well. (f) Water is to be used as the injection medium or fluid in conducting the initial injectivity tests and in the initial injection well. The source may be either from water wells drilled from the platforms now located in the project area or water from the Cook Inlet. Gas may also be used as an injection fluid to replace or supplement the water injection. The amounts to be injected daily will depend upon the availability of suitable fluids for injection, and upon the rate at which fluids can be injected into the injection well or wells, but will, in general, be the maximum amount which is available and can be injected, subject to any limitations which may be necessary for the protection of the correlative rights of the parties. (g) Exhibit "D" attached hereto shows the most recent available gas -oil ratio and oil and water production tests for the producing oil wells. - 4 - : .~ ~ (h) Development of the pools defined in Rule 2 to an approxi- mate density of two wells to each quarter section is necessary not only for primary production purposes, but in order to secure optimum conformance of the projected pressure maintenance or secondary recovery project. If this Application is granted, such development drilling will be carried out as rapidly as possible from each of the two platforms in accordance with the provisions of Rules I, 2, 3, and 4, above 0 Applicants believe however that the conducting of injectivity tests, and if injection of fluids proves to be feasible I the initiation of injection operations should not be delayed until all such development drilling has been carried out, and Applicants there- fore propose that, at any time after the granting of this application Pan American, as Operator for the affected.parties, be permitted to drill the proposed joint injection well at the approximate loea tion above set out and to complete said well as a producing oil well, and thereafter, upon giving notice thereof to the Committee, to convert the well from a producing well to an injection well, and that Shell be permitted to conduct in a suitable well or wells on the SAS acreage injectivity tests for the purpose of evaluating the feasibility of water injection. Applicants also believe that additional injection wells will be necessary within the project area, such injection wells to be secured either by the drilling of additional wells solely for injection purposes, or by the conversion of existing producing wells to injection wells. It may also be found desirable to drill producing wells in addition to those allowed and provided for in the Field Rules, or to convert in- jection wells to producing wells. In order to avoid unnecessary delays and secure the maximum efficiency of operation, the Field Rules should provide for such changes in injection locations, or producing locations and for the drilling of additional injection or producing wells to be per- mitted by the Committee as an administrative matter and without notice or hearing provided that Pan American Petroleum Corporation I as Oper- ator of the lease held by the Chakachatna group, and Shell Oil Company, as Operator of the leases held by the SAS group, as the representatives of all affected parties, concur in the request therefor. (i) The pressure maintenance or secondary recovery operations will be carried out under a cooperative agreement entered into between all of the parties on whose behalf this Application is filed, (these being the only affected owners). Part of the pressure maintenance or secondary recovery operations will be carried on by Pan American Petroleum Corporation from the existing platform on the Chakachatna lease and the balance by Shell Oil Company from the existing plat- form on the SAS leases. v. To permit, facilitate and regulate pressure maintenance and secondary recovery by the injection of fluids into producing formations, the following additional Field Rules should be adopted: Rtùe 5, Fluid Injection ø The injection of fl uid into any of the pools described in Rule 2, for the purpose of pres sure maintenance or secondary recovery or of conducting injectivity tests, is hereby permitted, subject to the following requirements: - 5 - \~ "-'" (a) FI uid' injected into MGS Pool A must be segregated from and injected separately in the well bore from fl uid injection through the same well into any other pool. (~) Fl uid to be injected into MGS Pools B, C, and D, may be commingled in the well bore and injected s,imultaneously into all three pools, but must be segregated from and injected separately in the well bore from fl uid injected through the same well into any other pool. (c) Fluid to be injected into MGS Pools E, F, and G may be commingled in the well bore and injected si_multaneously into all three pools, but must be segregated from and injected separately in the well bore from fluid injected through the same well into any other pool. (d) The same well may be used for both injection and producing purposes simultaneously provided: that the requirements of Rule 3, and of Rule 5 (a), (b) and (c) above are met, and there is an adequate shut-off between that part of the well used for injection purposes and that part used for production purposes. Rule 6, Lease Line Well. The drilling of a well to be completed in the pools defined in Rule 2, at a location as nearly as practicable upon the township line between Township 8 North and Township 9 North and the boundary , line separating Lease ADL 17595 from Lease ADL 18754 is hereby per":' mitted, upon a showing being made to the Committee that an appro- priate agreement therefor has been entereq into by all affected parties, including the State of Alaska as lesso1\. ~aid well may be comp!~!ed. ;;;;":~·....u-_·'''''~''''·'''·'·'''"''''''-~.q""",>"_;::,,,~.~,,-_,,~>--,,,,--,,,,""'='r-.,c.,..~~~'~""~-" - -~, "''''_~"<.,~''' ~!tº.¡:>!,.ºg.uçJ~d/a~ an oi1~.~l!

Said well may at any-tfme thereafter be converted to injection purposes. The Committee shall be notified of the effective date of the change. Rule 7, Administrative Approval of Changes in Pressure Maintenance or Secondary Recovery Operations. The Committee may upon a showing that the operators of ea'ch of the lea~E!.~, as the representatives of all affected parties, concur in the request therefor and that appropriate and adequate casing, cement- ing, and testing has been, or will be, carried out, authorize any of the following operations as an administrative matter and without notice or hearing: (a) The conversion to injection purposes of any well initially completed either as a producer of oil or as a dry hole. (b) The drilling for injection purposes of a well or wells at any location. (c) The conversion from injection purposes to producing status of any well or wells. - 6 - '-' .

(e) The commingling in the well bore of fluid produced by a well from any pool defined by Rule 2, with fl uid produced by said well from any other pool or pools defined by Rule 2. (f) The commingling in the well bore of fluid injected through a well into any pool as defined by Rule 2 with fluid i~jected through said well into any other pool or pools as defined by Rule 2. VI. Except as specifically set out in the Field Rules proposed by this Application I operations within the area to be, covered by the Field Rules should remain subject to the general rules of statewide application adopted by the Oil and Gas Conservation Committee. VII. Pan American Petroleum Corporation, Phillips Petroleum Company, Sin- clair Oil & Gas Company and Skelly Oil Company, comprising the Chakachatna group of companies,' and Shell Oil Company, Standard Oil Company of Calif- ornia and the AtlantiC Richfield Company, comprising the SAS group of com- panies, are the owners of all leases within the area which would be affected by the Committee's Order herein, and are also the owners of all leases with- in one-half mile from the outer boundaries of said area .
