FINDINGS: 1. Hilcorp is the operator of the Trading Bay Unit and is the operator of the proposed TBU G -02RD development oil well that is located on the west side of the Cook Inlet, Kenai Peninsula Borough, Alaska. 2. The TBU G -02RD well is an offshore, deviated development oil well with a surface location 1829 feet from the south line and 1480 feet from the east line of Section 29, T9N, R13W, Seward Meridian (S.M.). The projected bottom -hole location is 2330 feet from the north line and 770 feet from the east line of Section 32, T9N, R13W, S.M. 3. The TBU G -02RD well is located entirely within State of Alaska Lease ADL- 17594. 4. The TBU G -02RD well is currently completed in the Hemlock Oil Pool. This well will be re- completed in the Middle Kenai G and Hemlock Oil Pools within an area governed by Conservation Order No. 80. 5. The TBU G -02RD well is located within 1,000 feet of wells that are, or may be capable of, producing from the Middle Kenai G or Hemlock Oil Pools. 6. Regulation 20 AAC 25.055(a)(3) specifies that the drilling unit for an oil pool is a governmental quarter section, and that a well may not be drilled or completed closer than 1,000 feet to any well drilling to or capable of producing from the same pool. However, Rule 5 of Conservation Order No. 80 specifies in part that the AOGCC "...may authorize the conversion or drilling of any well at any location...reasonably designed to further the purposes of the project." 7. The re- completion of TBU G -02RD is designed to maximize recovery from the Hemlock and Middle Kenai G Oil Pools at McArthur River Field by accessing un- drained reserves in both oil reservoirs that cannot be reached by wells conforming to applicable spacing restrictions. 8. In conformance to Rule 5 of Conservation Order No. 80, Hilcorp has given notice of this request to all potentially affected landowners, owners and operators —those within 1,000 - foot radius of the TBU G -02RD well —the State of Alaska and Hilcorp Alaska, LLC. Hilcorp sent notice of its application to the State of Alaska by certified mail in December 4, 2012. The AOGCC received no objection or comment regarding Hilcorp's request. AA 80.91 Amended • January 3, 2013 Page 2 of 2 CONCLUSIONS: 1. An exception to the well spacing provisions of 20 AAC 25.055(a)(3) is necessary to allow re- completion of the TBU G -02RD development oil well in order to maximize recovery of reserves. 2. Under 20 AAC 25.055(a), drilling unit and well spacing requirements prescribed by pool rules —Rule 5 of Conservation Order No. 80—supersede o ersede the statewide p p spacing requirements of 20 AAC 25.055(a)(3). 3. A spacing exception to allow re- completion of the TBU G -02RD development oil well is consistent with sound engineering and geoscience principles and will not result in waste or jeopardize correlative rights of adjoining or nearby owners. NOW THEREFORE IT IS ORDERED: Hilcorp's December 4, 2012 application for an order granting an exception to the well spacing requirements of 20 AAC 25.055(a)(3) to allow re- completion of the TBU G -02RD development oil well is approved. Hilcorp may proceed as long as it complies with the terms of the Trading Bay Unit agreement, applicable Alaska laws, and all other legal requirements.

FINDINGS: 1. Hilcorp is the operator of the Trading Bay Unit and is the operator of the proposed TBU M -31 B development oil well that will be located on the west side of the Cook Inlet, Kenai Peninsula Borough, Alaska. 2. The TBU M-318 well will be an offshore, deviated development oil well with a surface location 970 feet from the north line and 516 feet from the west line of Section 33, T9N, R13W, Seward Meridian (S.M.). The projected bottom -hole location is 2554 feet from the south line and 1769 feet from the west line of Section 33, T9N, R13W, S.M. 3. The TBU M -31B well will be located entirely within State of Alaska Lease ADL- 18730. 4. The TBU M -31 B well will be drilled to, and completed in, the Middle Kenai G and Hemlock Oil Pools within an area governed by Conservation Order No. 80. 5. The TBU M -31B well will be located within 1,000 feet of, and within the same governmental quarter section as, wells that are, or may be capable of, producing from the Middle Kenai G or Hemlock Oil Pools. 6. Regulation 20 AAC 25.055(a)(3) specifies that the drilling unit for an oil pool is a governmental quarter section, and that a well may not be drilled or completed closer than 1,000 feet to any well drilling to or capable of producing from the same pool. However, Rule 5 of Conservation Order No. 80 specifies in part that the AOGCC "...may authorize the conversion or drilling of any well at any location...reasonably designed to further the purposes of the project." 7. TBU M -31B is designed to maximize recovery from the Hemlock and Middle Kenai G Oil Pools at McArthur River Field by optimizing the well path to access un- drained reserves in both oil reservoirs. AA 80.89 Amended • November 2, 2012 Page 2 of 2 8. In conformance to Rule 5 of Conservation Order No. 80, Hilcorp has given notice of this request to all affected parties —i.e., all owners, landowners, and operators within 1,000' of the TBU M-31B development oil well. CONCLUSIONS: 1. An exception to the well spacing provisions of 20 AAC 25.055(a)(3) is necessary to allow drilling and completion of the TBU M -31B development oil well in order to maximize recovery of reserves. 2. Under 20 AAC 25.055(a), drilling unit and well spacing requirements prescribed by AOGCC pool rules —Rule 5 of Conservation Order No. 80— supersede the statewide spacing requirements of 20 AAC 25.055(a)(3). 3. A spacing exception to allow drilling and completion of the TBU M -31 B development oil well is consistent with sound engineering and geoscience principles and will not result in waste or jeopardize correlative rights of adjoining or nearby owners. 4. An exception to the requirements of 20 AAC 25.055(a)(3) will not promote waste or jeopardize correlative rights. NOW THEREFORE IT IS ORDERED: Hilcorp's October 10, 2012 application for an order granting an exception to the well spacing requirements of 20 AAC 25.055(a)(3) to allow drilling and completion of the TBU M -31B development oil well is approved.

Tabler Land Manager, Alaska Hilcorp Alaska, LLC 3800 Centerpoint Drive, Suite 100 Anchorage, AK 99524 -4027 RE: Docket CO -12 -19 — The amended application of Hilcorp Alaska, LLC (Hilcorp), operator of the Trading Bay Unit (TBU), to drill and complete the TBU M -31A development oil well within 1,000 feet of a well that is, or may be, capable of producing from the same pools and to drill and complete more than one well in a governmental quarter section. Dear Mr. Tabler: By a letter dated June 26, 2012, Hilcorp requests an order allowing drilling and completion of the of the TBU M -31A development oil well within 1,000 feet of, and within the same governmental quarter section as, a well that is, or may be, capable of producing from the same pool. FINDINGS: 1. Hilcorp is the operator of the Trading Bay Unit and is the operator of the proposed TBU M-3 1 A development oil well that will be located on the west side of the Cook Inlet, Kenai Peninsula Borough, Alaska. 2. The TBU M -31A well will be an offshore, deviated development oil well with a surface location 970 feet from the north line and 516 feet from the west line of Section 33, T9N, R13W, Seward Meridian (S.M.). The projected bottomhole location is 2544 feet from the south line and 2064 feet from the west line of Section 33, T9N, R13W, S.M. 3. The TBU M -31A well will be located entirely within State of Alaska Lease ADL0018730. 4. The TBU M-3 1 A well will be drilled to, and completed in, the Middle Kenai G and Hemlock Oil Pools within an area governed by Conservation Order No. 80. 5. The TBU M -31A well will be located within 1,000 feet of, and within the same governmental quarter section as, wells that are, or may be, capable of producing from the Middle Kenai G or Hemlock Oil Pools. 6. The statewide spacing requirements of 20 AAC 25.055(a)(3) specify that the drilling unit for an oil pool is a governmental quarter section, and that a well may not be drilled or AA 80.88 Amended • July 17, 2012 Page 2 of 3 completed closer than 1,000 feet to any well drilling to or capable of producing from the same pool. However, Rule 5 of Conservation Order No. 80 specifies in part that the AOGCC "...may authorize the conversion or drilling of any well at any location...reasonably designed to further the purposes of the project." TBU M -31A is designed to maximize recover 7. U g recovery from the Hemlock and Middle Kenai G Oil Pools at McArthur River Field by reconfiguring producer- injector pairings in the Middle Kenai G Oil Pool and optimizing the well path to better access both oil reservoirs. CONCLUSIONS: 1. An exception to the well spacing provisions of 20 AAC 25.055(a)(3) is necessary to allow drilling and completion of TBU M-3 1A development oil well in order to maximize recovery of reserves. 2. Under 20 AAC 25.055(a), drilling unit and well spacing requirements prescribed by AOGCC pool rules —Rule 5 of Conservation Order No. 80— supersede the statewide spacing requirements of 20 AAC 25.055(a)(3). 3. A spacing exception to allow drilling and completion of the TBU M -31 A development oil well is consistent with sound engineering and geoscience principles and will not result in waste or jeopardize correlative rights of adjoining or nearby owners. 4. An exception to the requirements of 20 AAC 25.055(a)(3) will not promote waste or jeopardize correlative rights. NOW THEREFORE IT IS ORDERED: Hilcorp's June 26, 2012 application for an order granting an exception to the well spacing requirements of 20 AAC 25.055(a)(3) to allow drilling and completion of the TBU Z development oil well is approved. Hilcorp may proceed as long as it complies with the r the Trading Bay Unit agreement, applicable Alaska laws, and all other legal requireme r s DONE at Anchorage, Alaska and dated July 17, 2012._ * � ~ � 44 0N Cot*P (ity WAJIMar Cathy /P.

Thanks, Luke Keller Drilling Engineer Hilcorp Alaska, LLC 907 - 777 -8395 From: Matt Frankforter Sent: Tuesday, July 17, 2012 11:00 AM To: 'steve.davies @alaska.gov' Cc: Luke Keller; Judy Stanek; Trudi Hallett Subject: M -31A Spacing Exception Steve, We moved the well path /bottom hole location of the M -31A well in order to optimize the reservoir management of both the Hemlock and G Zone oil sands while overcoming the mechanical and directional limitations imposed by re- drilling the M -31 well. The original plan was based on targeting the Hemlock as the primary objective in the well, however, we are beginning a work over program on the Grayling platform and reconfiguring the G Zone producer- injector pairings in the vicinity of the M -31A well. We were unable to optimize a well path for both targets without moving more than 500 feet from the original plan. We found that a well path /bottom hole location approximately one half mile to the east would improve the management of both the Hemlock and G Zone reservoirs. Don't hesitate to contact me if you have any questions.

Attached are 2 screenshot maps 1 for G- Zone and 1 for Hemlock. The maps show the updated well path for M -29A. This is a replacement for a failed producer (M -29) and will be completed initially in the H -3 to H -7. The original well M -29 was a G -Zone, Hemlock and West Foreland completion. The proposed completion interval will be between 10317' and 12228' (H -3 to H -7). The following distances are mid -perf. in the proposed completion interval of M -29A to mid -perf. of some of the closest wells. The perf. intervals are in green and are 100' in dia. around the well bore. For the Hemlock. The closest wells are G -4RD, G -32, M -25, G -20 and G -33. As you can see on the map G -32 was not completed in the Hemlock and is a G -Zone only producer. M -25 the distance from the midpoint of the perf. interval to the midpoint of the intended completion interval in the Hemlock is about 287'. G -4RD the distance from the midpoint of the perf. interval to the midpoint of the intended completion interval in the Hemlock is about 783'. G -20 the distance from the midpoint of the perf. interval to the midpoint of the intended completion interval in the Hemlock is about 826'. G -33 the distance from the midpoint of the perf. interval to the midpoint of the intended completion interval in the Hemlock is about 1775'. For the G -Zone. The closest wells are G -4RD, G -32, M -25, G -20, G -33 and M -31. The G -Zone may be completed from about 9190' to 9800'. M -25 the distance from the midpoint of the perf. interval to the midpoint of the intended completion interval in the G- Zone is about 1278'. G -4RD the distance from the midpoint of the perf. interval to the midpoint of the intended completion interval in the G- Zone is about 1242'. G -20 the distance from the midpoint of the perf. interval to the midpoint of the intended completion interval in the G- Zone is about 890'. G -33 the distance from the midpoint of the perf. interval to the midpoint of the intended completion interval V in the G- Zone is about 1232'. M -31 the distance from the midpoint of the perf. interval to the midpoint of the intended completion interval V in the G- Zone is about 2214'. G -32 the distance from the midpoint of the perf. interval to the midpoint of the intended completion interval V in the G- Zone is about 2515'.

There are no plans to perforate the Hemlock interval in the G -32 wellbore but it is capable of production from this reservoir.

I have a short introductory statement: Concurrent with the development of the McArthur River Hemlock Oil Pool within the Trading Bay Unit area,. exploration and testing has been conducted which has resulted in the discovery of oil in paying q. uantities from two additional pools; the McArthur River Middle Kenai "G" Oil ~'ool and the McArthur River West Foreland Oil Pool. On August 22, 1969, Union Oil Company of Calif- ornia, as unit operator, filed with the Alaska Oil and Gas Conservation Committee an application for definition of these pools. In the interest of economy of time, I request the application with Exhibits A through F be entered into the record of this hearing without reading. Union has now -- Union now presents for your consideration the following proposed Conservation Order: The area which this Conservation Or,.er is applicable is described as follows: ~ownship 8 North, Range 13 West~ Seward Meridian Sections 1 through 8 inclusive: Section 9: Section 16: Section 17 through 20 inclusive: Section 29: Section 30: All W'l/2, NE 1/4 w 1/~ All NW 1/4 NE 1/4 (2) Township 8 North,_Range ~4 West, Seward Meri'dian Section 1: Ail Section 12: E 1/2 of the NW 1/4 Township 9 North~ Ran$~. 13 west, Seward Meridian Section 9: Section 14: Section 15 through 17 inclusive: Section 18: Section 19 through 22 inclusive: Section 23: Section 26: Section 27 through 34 inclusive: Section 35: S 1/2 sw Ail s 172 Ail W 1/2 w 1/2 Ail NW 174 ~own~hip~_9...No~t~h,_R. ange . !4_West ~ Seward Meridian Section 24: E 1Z2 Section 25: E 1/2 Section 36: NE 1/~4 Rule 1. Definition of pqols McArthur River Middle Kenai "G" Oil Pool correlates with the interval 9,116' through 9,695' drilled depth in the Trading Bay Unit State G-7 well. (b) McArthur River West Foreland Oil Pool correlates with the interval 10,208' to 11,208' drilled depth in the Trading Bay Unit State G-7 well. Rule 2. Casi. ng and Cem~nt.i.n~ R~q~uirements (a) Surface casing shall be landed not less than 2,000 feet -- at not less than 2,000 feet and cement shall be circulated to the ocean~ -- sea floor. Casing and control e~.uipment shall be hydrostatically tested to not less than 1~000 pounds per square inch pressure before drilling the shoe. (b) Production casing shall be landed through the completion zone and cement shall cover and extend to at least 500 feet above each potentially productive sand interval. The use of multi-state cement- ing procedures shall be permitted. Alternatively, a casing string shall be adequately cemented at an intermediate point and a liner landed through the completion zone. If a liner is run, the annular space behind the liner shall be filled with cement to at least 100' above the casing shoe or the top of the liner shall be squeezed with sufficient cement to provide at least 100' of cement between the liner (3) and the casing annulus.

Rule 3. Bottom Hole Pressure Surveys~ A key well bottom hole pressure survey shall be made in the McArthur River Middle Kenai Oil Pool and the McArthur River West Foreland Oil Pool upon Committee request; provided, however, such surveys shall not be req~uired more often than once in every -- in any calendar year. The time and length of survey, number and loca- tions of wells, datum and other details will be determined by the Committee upon consultation with the operators. In support of the proposed Conservation Order, Mr. Graydon H. Laughbaum~ Jr. and Mr. Gary S. Way will present geologic and engineer- ing testimony to prove the pools have their respective lithologic and reservoir characteristics thus indicating their separateness from any other pool. Testimony will also show the proposed casing and cement~ requirements will effectively isolate the pools to prevent comming- ling with one another or other pools in the well bore. It will also be shown that sufficient data may be obtained from key well bottom hole ~ressure surveys to maintain effective reservoir control. Mr. Laughbaum's qualifications have bee~ previously presented in Februar~ 1969 in testimony for Conservation Order No. 71 and accepted as suffi- cient to establish him as an expert witness~ I request you acknow- ledge Mr. Laughbaum as an expert without again presenting his q~uali- fications. Mr. Burrell: There will be no objections. Mr. An~.erson: Thank you Mr~ Chairman. Mr. Gary S~ Way attended Central Michigan University for two years and the University of Oklahoma for three ~ears~ receiving a B.S. degree in petroleum engineering from the latter institution in June, 1961o Since gradua- tion he has attended seventeen industry sponsored schools in speciali- zed areas of production and reservoir engineering. Mr. Way is a member of the Society of Petroleum Engineers of AIME and the Tau Beta Pi and Sigma Tau national honorary engineering fraternities. He is (4) also a member of the Pi Epsilon Tau national honorary petroleum engineering fraternity. Mr. Wa.~ has eight years petroleum engineer- ing experience in the oil industry. Since June 1961 -- excuse me -- from June 1961 to February 1962 he worked in the Illinois Oil Company in southern Illinois. From February 1962 to February 1964 he worked in Texas for Texaco, also in Illinois. He joined the Pure Oil Company as a reservoir engineer in February 1964 and worked on reservoirs in Illinois, Michigan, Kentucky and West Virginia. Following the merger of Union and Pure~ Mr. Way was transferred to Casper, Wyoming as a reservoir engineer and worked on numerous fields in Wyoming, Montana, North Dakota, Nebraska, Utah and Colorado. He was transferred to Alaska in June 1969, where he is a reservoir engineer in Union's Anchorage district, as well as Union's representative to the Trading Bay Unit engineering and planning group.Mr. Way's experience has included work in a wide variety of reservoirs, including both primary and secondary recovery. I request Mr. Way be established as an expert witness. Mr. Burrell: There will be no objections. His qualifica- tions are accepted. Mr. Anderson: We'll call on Mr. Laughbaum now to present geologic testimony in the matter at hearing. Mr. Laughbaum: Graydon Laughbaum speaking° The following geologic testimony is presented to support field rules for the McArthur River West Foreland Oil Pool and the McArthur River Middle Kenai "~" Oil Pool within the area shown on Exhibit 1. Exhibit 1 is a current structure map on top West Foreland, the upper limit of the West Foreland oil pool. The exhibit is at a scale of 1" = 2,$00'. Geo- logic testimony presented on February 27, 1969 in support of Conserva- tion Order No. 71 show that the West Foreland horizon has actual alignment and structual configur~ation ~ similar to the Hemlock o~ Exhibit 2 is a current structure map of the Middle Kenai "G" interval drawn on the base of a coal, approximately 200 feet above the top of the Middle Kenai "G" Oil Pool. This contour point was selected because it has distinct continuity across the structure in the lower Middle Kenai inter~al. Map scale again is 1"=2000'. That~estimony also shows the ~iddle Xenai (5) alignment and configuration to be similar to the Hemlock. May I direct your attention to Exhibit III, an electric log of the Union, Trading Bay Unit State G-7, which illustrates the productive McArthur River Middle Kenai "G" Oil Pool and McArthur River West Foreland Oil Pool. As defined in our application§ the stratigraphic limits of the Middle Kenai "G" Oil"Pool correlate with the interval 9116' to 9695', drilled depth, in the directed well, Trading Bay Unit State G-7. The stratigraphic limits of the West Foreland Oil Pool correlate with the interval 10,208' to 11,208' drilled depth, in the G-7 well. Exhibit III also shows the previously defined McArthur River Hemlock Oil Pool and the McArthur River Middle Kenai'~ Gas Pool. Exhibit IV, a northwest-southeast structure section, which extends from the ARCO Middle River No. 2 across the central part of the McArthur River Field to the Pan Am North Redoubt State No. 1,i'ncludes the lower portion of the Trading Bay Unit State G-7 well. The Middle Kenai "G" Oil Pool unconformably overlies the McArthur River HEMLOCK Pool and occurs approximately 4000 feet below the McArthur River Middle Kenai Gas Pool. The Middle Kenai "G" Oil Pool is the basal unit of the Middle Ground Shoals member of the Tyonek Formation in the McArthur River Field area. The "G" Oil Pool is composed 'of firm, silty and clayey sand and conglomerate interbedded with siltstone and coal. Analysis of a 25'x4" diameter conventional core from the Middle Kenai "G" Oil Pool in the Trading Bay Unit State G-7 well resulted in permeability values which ranged from zero to 277 millidarcies, and porosity values from 9.1 to 22.6%. Average permeability was 65 millidarcies, and porosity 18.1To. The area of accumulation for the Middle Kenai "G" Oil Pool is not yet defined. Log analysis and drill stem tests conducted to date indicate that the oil accumulation for the Middle Kenai "G" Oil Pool occurs above -9250', and that the projected downdip limit may be at or below -8500' on the Top "G" Structure Map, Exhibit II. Additional drilling may further define the limits of accumulation. The basal Kenai, West Foreland Oil Pool of the West Foreland Formation occurs unconformably below the Hemlock Oil Pool. The West Foreland Oil Pool is composed of clayey and silty sands ranging to.i~.elatively clean sands., pebbly sands, and conglomerate, interbedded with siltstone and minor coals. The West Foreland is characteristically tuffaceous. The available log data demonstrates the variable lithology of the West Foreland Oil Pool. Analysis of a 30' x 4" converfional core from the West Foreland Oil Pool in the Union Trading Bay Unit State G-19 well resulted in permeability values which ranged from 2.2 to 189 millidarcies, and porosity values from 5.9 to 19.4%. Average permeability was 101.6 millidarcies and average porosity 15.7%. The area of oil accumulation for the West Foreland Oil Pool at the McArthur River Field has been approximately determined by cores, ~o.g analysis, and drill- stem test data. The projected downdip limit of accumulation is bounded approximately by the -9720' structure contour as shown on the Top West Foreland Structure Map, Exhibit I. Additional drilling may further define the limits of accumulation. (6) The McArthur River Middle Kenai "G" Oil Pool and the McArthur River West Foreland Oil Pool are separate and distinct pools, and are dissimilar with the previously defined McArthur River Hemlock Oil Pool and the McArthur River Middle Kenai Gas Pool. Stratigraphic separation, lithology contrast, and accumulation limit difference, support the applicant's request to establish the Middle Kenai "G" Oil Pool and the West Foreland Oil Pool as separate pools by conservation order, as proposed. Mr. Anderson: Mr. Chairman, this is Bob Anderson. I would like now to call on Mr. Gary Way to give engineering testimony in the matter at hearing. Mr. Burrell: May I ask one question here. When you mentioned the exhibits, you mentioned "A"through"F" Mr. Anderson: "A" through "F" included in the transmittal -- or the letter requesting the hearing itself. This is true. Mr. Bur~Mr. Laughbaum just mentioned "1" through "4" and I would like to ask if~~were prepared by himself or under his supervision. Mr. Anderson: Yes sir, they are most recent -- based on most recent -- Mr. Burrell: Alright then. , Mr. Anderson: Mr. Way. ,~-~~ Mr. Way: Gary Way speaking. The purpose of my testimony is to support'[~ ~ application for Middle Kenai G and West Foreland pool definition in the McArthur River Field by presenting engineering data to show that they are separate reservoirs and that both are separate from the Hemlock reservoir. I will also comment o~s proposed field rules for'pressure surveys and casing and cementing programs. Please refer to Exhibit V which is a comparison :.~fthQ oil compositions for the three reservoirs. The G and West Foreland samples were obtained during drill stem tests of the Trading Bay Unit State G-7 well. The Hemlock sample was taken 'during a drill stem test in the ~_t!an*ic ?~~ MCArthur State No. 1. All analyses were made with recombined surface samples by the same commercial laboratory. The exhibit shows the mol percent of each component in the total well stream. You will notie~ the difference in concentration of the various components and in particular the large differences in methane and heptanes plus in each sample. Methane concentrations range from a high of 42.58 mol percent in the G to a low of 15.85 mol percent in the West Foreland. Conversely, heptanes plus range from a low of 39.21 mol percent in the G to a high of 58.65 mol percent in the West Foreland. There are also some differences in the type and amount of non-hydrocarbon materials present such as nitrogen and carbon dioxide. (7) Exhibit VI is another comparison of labratory test results on the above samples. Differential liberation tests were made at the respective reservoir temperatures to describe the hydrocarbon behavior in each pool as reservoir pressure is reduced. Also, flash liberation tests were made at several surface operating conditions to simulate the hydrocarbon behavior in surface vessels. The results of these tests show considerable difference for the three samples. As can be seen the G has a bubble point of 3810 psig compared to the original zone pressure of 4009 psig. In other words, it is not saturated with gas and is said to be undersaturated by 199 psig. Comparatively, the Hemlock and West Foreland are under saturated by 2463 psig and 3271 psig respectively. The amount of gas in solution in the reservoir also ranges widely from 738 standard cubic feet per barrel for the G to 404 and 2 71 standard cubic feet per barrel for the Hemlock and West Foreland respectively. Other parameters such as flash separator gas oil ratios, oil volume factors and oil viscosities have similar ranges. The data tabulated on Exhibits V and VI demonstrate substantial differences in composition and pressure-volume-temperature behavior for the G, Hemlock, and' West Foreland crude oils and indicate that they are indeed from separate reservoirs. In addition to the previously mentioned differences in the reservoir fluids, pressure data also indicates that the G, Hemlock, and West Foreland are separate reservoirs. Drill stem tests of the Trading Bay Unit State wells G-30 and D-19 in July' 1969 showed that the G and West Foreland had virgin pressure while the '~lock pressure had declined approximately 1350 psig as a result of production. The three pools are not in pressure communication. In light of this pressure and fluid data, it must be concluded that the G, Hemlock and West Foreland are separate reservoirs. The existing field rules governing casing and cementing practices for the Trading Bay Unit Hemlock'.~pool are sufficient to protect all porous zones if adopted for the Middle Kenai G and West Foreland pools. It is normal practice to set inter- mediate protective casing below the G sands and run a liner from there to total depth using 100 feet or more of liner lap. The intermediate casing is cemented with suffi- cient volume to cover the G sands with approximately 2000 lineal feet of cement. The liner is cemented along its entire length. To drill and safely complete G wells requires no change from current practice. To drill and safely complete West Foreland wells require,s only an additional length of liner. In order to monitor the performance of the Middle Kenai G and West Foreland reservoirs, it will not be necessary to schedule more than one key well bottom hole pressure survey per year. As a matter of prudent operation, it has become customary for operators to run frequent pressure buildup tests to determine wellbore damage, formation flow capacity, the existence of permeability barriers and reservoir pressure. When the pressure '! data obtained during these tests is added to annual pressure survey data, it is very adequate to monitor individual pool performance. (8) Mr. Anderson. Mr. Chairman, this is Bob Anderson. expert witness testimony on the matter at hearing today. This concludes our Mr. Burrell' Did you wish to submit Exhibits V and VI ? Mr. Anderson- Yes, I'd like to ask if you would include Exhibits I through VI as part of the testimony of this hearing today. Mr. Burrell. Were Exhibits V and VI prepared by Mr. Way ? Mr. Anderson. Yes sir. Mr. Way: Yes sir. Mr. Burrell. Very well, Exhibits I through VI will be included as part of the testimony of the matter at hearing. Mr. Anderson. Mr. Chairman, if you would like to call a slight recess at this point we could pass out written copies of the testimony that you've heard and if any of your Committee would like to peruse prior to asking questions. Mr. Burrell. We'll take a ten minute recess. (Ten Minute Recess Followed) Mr. Burre_ll:.~ e~meet~n%i.~f.e~co~?_~ned. Mr. Anderson, I wondered if we could ask ~ --~~ght,V~ ~~~'. , Prior to going back through this entire tape, tl~is testimony that you ~es~ted,~~ a copy of/that'~bstantially or accurately reflect what was stated ? Would you permit that to' be introduced into evidence as testimony, rather than listening to this tape ? Mr. Anderson: This point I would so request that this is the proper way to handle it. It is a true and accurate copy of what is on the tape -- if these fellows read properly. (laughter) Mr. Burrell. all[there are jections then I would like the record to reflect the Introduction Of ~stimon¥ t_o Support the Application ~br ~.~eld Rules For The McArthur Pd. ver Middle KENAI "G_" Oil Pool and the McArthur.,'.~il~ver West Foreland Oil Pool, Conservation File_ ~80 is hereby accepted into the record as the testimony given by the applicant. Just to identify, let us designate this as Exhibil A. MR. Anderson: Also there is already an Exhibit A on file in this matter and that was the Application for HEARING , where we submitted Exhibits A through F. Maybe we 'ought to make this -- Mr. Burrell: Exhibit G, how's that ? Mr. Anderson: That's great. Mr. Burrell: Do you have any further testimony? (9) Mr. Anderson: present. No, Mr. Chairman, this concludes the testimony we wish to Mr. Burrell: Are there any questions ? Mr. Marshall: I'd like to ask -- I'm Tom Marshall. I'd like to ask whoever wishes to answer this question to recapitulate the testing history. The formation testing history of the West Foreland formation. We have quite a large interval lined on our logging exhibit, and I would apprec.iat~ it if any of you gentlemen would give us a summary of the ~,.~,~.]r.,,~'~ f~'~'~"*~'~his formation, as indicated by testing. ; Mr. Laughbaum: Graydon Laughbaum speaking. In the Trading Bay Unit's State Lease G-7, we tested the sand located at approximately 11,150'. Oil was recovered on that test but did not flow, however. Additionally in the G-7 well, the interval from approximately 10,585 to 10,795 was tested. Recovered oil at a rate in excess of a thousand barrels a day. This established the discovery for the West Foreland interval. Additionally in the G-30 well, we tested various sands from the base of the McArthur River Hemlock Oil Pool. On the log that you're looking at, this occurs at 10,208. We tested sands from that point down to the equivalent sand which appears on the Trading Bay Unit State G-7 at 10,585 approximately. Additionally in the G--the Trading Bay Unit State G-31, the sand that is equivalent to the G-7 sand at 10,585 was tested; recovered water. This to the best of my knowledge is what we have tested in the McArthur River West Foreland Oil Pool. Mr. Marshall: Graydon, did you see any af[e¢~t, onShe productive rates, by such things as the swelling of clays, ~/%3~. ~'~" .... ~ l~thological descri- ptions of this formation was very heavy with ..>[ ¢~ ~.,, ~ ~ C[~.$, Mr. Laughbaum: Graydon Laughbaum speaking. On the test that I mentioned in the G-3 0 well, in the upper portion --the upper sands, the well did not flow to the surface, so we subsequently completed with casing guns, and feel that we do have production from this interval. On the particular test it did produce oil, but did not flow. Perhaps this is a function of the clay in the formation. I do not believe though that in the sands that I mentioned, that were tested in G-7, that we saw this--any relation as far as the testing there, as to whether we were clay or not. Mr. Marshall: Thank you. Mr. Gilbreth: Easy Gilbreth. Do you have enough information at this stage of the game to determine whether or not the permeability is directional ? I notice that rather low and high areas . Mr. Laughbaum: I think the range here is really due to the type of layering, if you will, that we have within a particular interval. In this case the cored intervals. I really can't give a firm answer on what exact type of permeability we're talking about, and how it might relate through the total interval that we're considering. (10) Mr. Gilbreth: The tight streaks, are they relative over large areas or are these variable between wells ? Mr. Laughbaum; We haven't detailed that Part of it within the productive sands. I feel that to a large degree they could be correlate. Mr. Gilbreth: I'd like to ask Mr. Way in your proposed rule you provide-- you made the statement that the BHP survey of the year, on a key well basis, would be the following rules . You thought the operators would be taking pressures throughout the year2 Mr. Way: Yes sir. Mr. Gilbreth: Would your company --would be agreeable to making these pressures available to the Committee in the absence of Mr. Way: I'm sure that they would. Yes sir. Mr. Gilbreth: I'd like to ask if you had information that shows there is a barrier of permeability, permeability barrier--drainage barrier, if you please, between the Hemlock and the West Forelands, and between the Middle Kenai and Hemlock. In other words, a natural barrier separating these two indications. Mr. Way: Yes, sir. This !was more or less the thrust of my testi'mony in citing the pressures that we observed in the G-9 and the D-19 wells. We tested the Middle G and the West Foreland because these two zones--these tests were run as I said in July of 1969 and the reservoirs did have virgin pressure in them, while at the ~.~me period'6f :ti'me we had produced say perhaps 38 million barrels of oil out of the Hemlock, reservoir pressures were rising about--it--it had to climb about 1350~ they are not in pressure communications. We take this as proof positive that they are indeed separate reservoirs. Mr. Gilbreth: Maybe I misunderstood. Are these recombined separator sample analyses or bottom hole analyses'? Mr. Way: Those are recombined surface samples. Mr. Gilbreth: That is all. Mr. Burrell: Does the Committee have any other questions ? Mr. Kugler: This is Harry' Kugler. Do you propose to go along with the statewide rules as to spacing in the G well oil pool. Mr. Laughbaum: Graydon Laughbaum speaking. At this point, yes sir. Mr. Kugler: And in the West Foreland ? Mr. Laughbaum: Yes sir. (ll) Mr. Kugler: And the 1,000' distance between wells, this is adequate at this time ? Mr. Laughbaum. Yes sir. Mr. Burrell. Will you be setting up separate petitions for hearings Mr. Anderson: Bob Anderson speaking. Yes we certainly will be. This is of course a part of the unit agreement itself. Mr. Burrell. Committee and their advisors, is there any questions from anybody in the audience ? There being no further questions, the Hearing is closed.

LAUGHBAUM, IR., ACTING CHAIRMAN, GEOLOGIC SUBCOMMITTEE TRADING BAY UNIT AT A PUBLIC H'-EARING - SEPTf:MBER 23, 1969 - ANCHORAGE, ALASKA GEOLOGIC TESTIMONY The following geologic testimony is' presented to support field rules for the McArthur River, West Foreland Oil Pool and McArthur River Middle Kenai "G" Oil Pobl within the area shown on Exhibit I. Exhibit I is a current structure map on Top West Foreland, the upper limit of the West Foreland Oil Pool. The exhibit is at a scale of 1" = 2000'. Geologic testimony presented on February 27, 1969, in support of Conservation Order No. 71 shoWed that the West FOreland horizon has axial alignment and structural configuration similar to the Hemlock. That testimony also sho'wed the Middle Kenai alignment and Configuration to be similar to the Hemlock. Exhibit II is a current structure map of the M~ddle Kenai "G" interval drawn on the base of a coal, approximately 200 feet above the top of the Middle Kenai "G" Oil Pool. This contour point 'was selected because it has distinct continuity across the structure in the lower Middle Kenai interval. Map scale is 1" -- 2000'. May I direct your attention to Exhibit III, an electric log of the Union, Trading Bay Unit State G-7, which illustrates the productive McArthur River Middle Kenai "G" Oil Pool and McA.rthur'.River West Foreland Oil Pool. As defined in our application, the stratigraphic limits of the Middle Kenai "G" Oil Pool correlate 'with the interval 9116' to'9695', drilled depth, in the directed well, Trading Bay Unit State G-7. The stratigraphic limits of the West Foreland Oil Pool correlate with the interval 10,208' to 11,208' Geologic Testimony drilled depth, in the G-7 well. Exhibit III also shows the previously defined McArthur River Hemlock Oil Pool and the McArthur River Middle Kenai Gas Pool. Exhibit IV, a northwest-southeast structure section, which extends from the ARCO Middle River No. 2 across the central part of the McArthur River Field to the Pan Am North Redoubt State No. 1, includes the lower portion of the Trading Bay Unit State G-7 well. The Middle Kenai "G" Oil Pool unconform- ably overlies the McArthur River Hemlock Pool and occurs approXimately 4000 feet below the McArthur River Middle Kenai Gas Pool. The Middle .' Kenai "G" Oil Pool is the basal unit of the Middle Ground Shoals member of the Tyonek Formation in the McArthurRiver Field area. The "G" Oil Pool is composed of 'firm, silty and clayey sand and congl°merate interbedded . 'with siltstone and coal. Analysis of a 25' x 4" diameter conventional core from the Middle Kenai "G" Oil Pool in the Trading Bay Unit State G-7 well resulted in permeability values which ranged from zero to 277 millidarcies, and porosity values from 9.1 to 22.6%. Average permeability 'was 65 millidarcies, and porosity 18.1%. The area of accumulation for the Middle Kenai "G" Oil Pool is not yet defined. Log analysis and drill stem tests conducted to date indicate that the oil accumulation for the Middle Kenai "G" Oil Pool occurs above -9250', and that the projected do'wndip limit may be at or below -8500' on the Top "G" Structure Map, Exhibit II. Additional drilling may further define the limits of accumulation. Geologic Testimony The basal Kenai, West Foreland Oil Pool of the West Foreland Formation occurs unconformably below the Hemlock Oil Pool. The West Foreland Oil Pool is composed of clayey and silty sands ranging to relatively clean sands, pebbly sands, and conglomerate, interbedded with siltstone and minor coals. The ~fest Foreland is characteristically tuffaceous. The available 'log data demonstrates the variable lithology of the West Foreland Oil Pool. Analysis of a 30' x 4" conventional core from' the West Foreland Oil Pool in the Union Trading Bay Unit State G-19 well resulted in permeability values which ranged from 2.2 to 189 millidarcies, and porosity values from 5.9 to 19.4%. Average permeability 'was 101.6 millidarcies and average porosity 15.7%. The area of oil accumulation for the West Foreland Oil Pool at the McArthur River Field has been approximately determined by cores, log analysis, and drill-stem test data. The projected do'wndip limit of accumulation is bounded approximately by the -9720' structure contour as shown on the Top West Foreland Structure Map, Exhibit I. Additional drilling may further define the limits of accumulation. The McArthur River Middle Kenai "G" Oil Pool and the McArthur River West Fore/and Oil Pool are separate and distir{ct pools, and are dissimilar with the previously defined McArthur River Hemlock Oil Pool and the McArthur River Middle Kenai Gas Pool. Stratigraphic separation, lithology contrast, Geologic Testimony and accumulation limit difference, support the applicant's request to'establish the Middle Kenai "G" Oil Pool and the %~est Foreland Oil Pool as separate pools by conservation order, as proposed. ENGINEERING TESTIMONY TO SUPPORT THE APPLICATION FOR FIELD RULES McARTHUR RIVER MIDDLE KENAI "G" OIL P OOL AND THE McARTHUR RIVER WEST FORELAND OIL P O O L CONSERVATION FILE NUMBER 80 PRESENTED BY GARY S. WAY, RESERVOIR ENGINEER, UNION OIL COMPANY OF CALIFORNIA PUBLIC HEARING, SEPTEMBER 23, 1969 IN ANCHO~AGE, ALASKA The purpose of my testimony is to support Union's application for Middle Kenai G and West Foreland pool definition in the Mc.Arthur River Field by presenting engineering data to show that they are separate reservoirs and that both are separate from the Hemlock reservoir. I will also comment on Union's proposed field rules for pressure su~w-eys and casing and cement- lng programs. Please refer to Exhibit V xvhich is a. comparison of the oil compositions for the three reservoirs. The G and West Foreland samples were obtained du.r- lng drill stem tests of the Trading Bay Unit State G-7 well. The Hemlock sample was taken during a drill stem test in the Atlantic Ricl.~field McArthur State No. 1. All analyses were made with recombi, ned surface samples by the same commercial laboratory. The exhibit shows th.e mol percent o17 each. component in the total well stream. You will notice the di:fference in concentration of the various components and in particular the large differences in methane and heptanes plus in each, sample. Meth. ane concentrations range from a high. of 42.58 mol percent i.n the G to a low of 15.85 mol percent in the West Foreland. Conversely, hep- tanes plus range from a. low of 39.21 mol percent i.n the G to a high of 58.65 mol percent in the West Foreland. There are also some differences in the type and amount of non-hydrocarbon materials present such as nitrogen and Carbon dioxide. Page Exhibit VI is another comparison of laboratory test results on the above samples. Differential liberation tests were made at the respective reset- voir temperatures to describe the hydrocarbon behavior in each pool as reservoir pressure is reduced. Also, flash liberation tests were made at several surface operating conditions to simulate the hydrocarbon be- havior in surface vessels. The results of these tests show considerable difference for the three samples. As can be .seen the G has a bubble point of 3810 psig compared tothe original zone pressure of 4009 psig. In other words, it is not saturated with,gas and is said to be undersaturated by 199 psig. Comparatively, the Hemlock and West Foreland are under sam- rated by 2463 psig and 3271 psig respectively. The amount of gas in solu- tion in the reservoir also ranges widely from 738 standard cubic feet per barrel for the G to 404 and 271 standard Cubic feet per barrel for the Hem- lock and West Foreland respectively. Other parameters Such as flash separator gas-oil ratios, oil volume factors and oil viscosities have simi- lar ranges. The data tabulated on Exhibits V&VI demonstrate substantial differences in composition and pressure-volume-temperature behavior for the G, Hemlock, and West Foreland crude oils and indicate that they are indeed from separate reservoirs. Page 2 In addition to r~e previously mentioned differences in the reservoir fluids, pressure data also indicates that the G, Hemlock, and West Foreland are separate reservoirs. Drill stem tests o{ the Trading Bay Unit State wells G-30 and D-19 in July 1969 showed that the G and West Foreland 'had virgin pressure while the Hemlock pressure had declined approximately 1350 psig as a result of production. The three pools are not in pressure communica- tion. In light of this pressure and fluid data, it must be concluded that the G, Hemlock and West Foreland are separate reservoirs. The existing field rules governing casing and cementing practices for the Trading Bay Unit Hemlock pool are sufficient to protect ail porous' zones if adopted for the Middle Kenai G and West Foreland pools. It is normal practice to set intermediate protective casing below the G sands and run a liner from there to total depth using 100 feet or more of liner lap. The intermediate casing is cemented with sufficient volume to cover the G sands with approximately 2000 lineal feet of cement. The liner is cemented along its entire length. To'drill and safely complete G wells requires no change from current practice. To drill and safely complete West Foreland wells requires only an additional length of liner. Page 3 In order to monitor the performance of the Middle Kenai G and West Foreland reservoirs, it will not be necessary to schedule more than one . key well bottom hole pressure survey per year. As a matter of prudent operation, it has become customary for operators to run frequent pressure buildup tests to determine wellbore damage, formation flow capacity, the existence of permeability barriers and reservoir pressure. When the pressure data obtained during these tests is added to annual pressure survey data, it is very adequate to monitor individual pool per-- formance. Page 4 Final CONCLUSION OF TEST!~IONY Mr. Chairman, today's expert testimony £ully supports the proposed Conservation Order which properly defines the McArthur River Middle Kenai "G" and West Foreland Oil Pools, requires an adequate casing and cementing program to prevent commingling or contamination of these and other pools or zones and provides £or maintaining reservoir control by allowing annual pressure surveys. As Operator of the Trading Bay unit, Union Oil Company of Cali£c~rnia strongly and respectfully urges issuance of the Conservation Order presented to you. + + + · U-M ARCO + + + + + + ,. ! i RI3W t U-M A/KO I T N + i i i ' i ' ' I · , -J- ', ' W~:$T FOFIIELAND FORMATION .~_~ ....... ~. _.

The Middle Kenai "G" Oil Pool is composed of firm, silty and clayey sand and conglomerate, interbedded with siltstone and coal. The area of p.age 2 i/ Ia¢cumulation for the Middle Kenai "G" 0il Pool at McArthur River Field is not yet defined. Log analysis and drill stem tests conducted to date indicate that the oil accumulation for the Middle Kenai "G" Oil Pool occurs above -9250', · and that the projected down dip accumulation limit may vary between -8500' and -9250' on the enclosed Top "G" structure map, 'Exhibit C. Additional drilling may further define the limits of accumulation. The follo,~Jing porosity and permeability data is from t'he analysis of a 25 foot by 4 inch diameter conventional core taken in the interval 9368' to 9393' from san~is in the Middle Kenai "G'l Oil Pool in the Union, Trading Bay Unit, State G-7 well. Porosity. varies from 9.1 to 22.6 percent and averages 18.1 percent.. Permeability varies from zero to 2"77 millidarcys and averages 65 millidarcys. The above mentioned G-7 well was drill stem tested on 8/18/&8 (DST ,~'4) from perforations 9254-9269, 9374-9414, and 9480-9510 in the Middl'e Kenai "G~' Oil Pool. The test yielded an average flow rate of 1400 BOPD, 35.3° APl Gravity, with 2 percer, z mud cut on a 48/64" choke an~ pressure data as follows: IHP 4501#, IFP 1506:f, ISIP 3829~-~., FHP 4477#, FFP 1792~~ and FSI. P ~-Iest Foreland 0il Pool The West Foreland 0il Po°l underlies the t~cArthur River, Hemlock 0il Pool. The West Foreland 0il Pool is composed of clayey and silty sands ranging to ', relatively clean sands, pebbly sands, and conglomerate, interbedded with si ltstone and minor coal beds. The available log data demonstrates the vari- able lithologY of the West FOreland Oil Pool. The area of oil accumulation for the '~est Foreland 0il Pool at tlcArthur River Field has been approximately determined by cores, log analysis, and drill stem test data. This area of accumulation bou.qded approximately by the -9520' structure contour as shown .. . page 3 on the enclosed Top West Foreland structure map, Exhibit B. Additional drilling may further define the limits of accumulation. Analysis of a 30 foot by 4 inch conventional core taken between, the intervals 11,574' to 1"1,6041 from sands, in the West Foreland Oil Pool in the Union, Trading Bay Unit, State G-19 well, gave the following porosity and permeability data: porosity varies from 5.9 to 19.4 percent and averages 15.7 percent. Permeability varies from 2.2 to 189 millidarcys and averages IO1.6 mi llidarcys. The Union, Trading Bay Unit, State G-7 well was drill stem tested' on 8/15/68 (DST-//2) from perforations 10,586 to 10,660 in the ~,~est Fore'land Oil Pooi.

The Middle Kenai I'G~' Oil Pool is composed of firm, silty and clayey sand and conglomerate, interbedded with siltstone and coal. The area of page 2 accumulation for the Middle Kenai "G'~ Oil Poo] at McArthur River Field is not yet defined. Log analysis and drill stem tests conducted to date indicate that the oil accumulation for the Middle Kenai "G'' 0il Pool occurs above -9250', and that the projected down dip accumulation limit may vary between -8500' and -9250' on the enclosed Top "G" structure map, Exhibit C. Additional drilling may further define the limits of accumulation. The following porosity and permeability data is from the analysis of a 25 foot by 4 inch diameter conventional core taken in the interval 9368' to 9393' from sands in the Middle Kenai "G" Oil Pool in. the Union, Trading Bay Unit, State G-7 well. Porosity varies from 9.] to 22.6 percent and averages 18.1 percent. Permeability varies from zero to 277 millidarcys and averages 65 mi]lidarcys. The above mentioned G-7 well was drill stem tested on 8/18/68 (DST //4) from perforations 9254-9269, 9374-9414, and 9480-9510 in the Middle Kenai ''G~' Oil Pool. The test yi. elded an average flow rate of ]400 BOPD, 35.3°'APl Gravity, with 2_ percent mud cut on a 48/64" choke and pressure data as follows: IHP 4501//, IFP 1506//, ISIP 3829//, FHP 4477//, FFP 1792// and FSIP 3~29//. West Foreland Oi] Pool The West Foreland Oi] Poo] underlies the McArthur River, Hemlock Oi] Pool. The West Foreland Oil Pool is composed of clayey and silty sands ranging to relatively clean sands, pebbly sands, and conglomerate, interbedded with si]tstone and minor coal beds. The available log data demonstrates the vari- able ]ithology of the West Fore]and Oil Pool. The area of oil accumulation for the West Fore]and Oil Pool at McArthur River Field has been approximately determined by cores, log analysis, and drill stem test data. This area of accumulation bounded approximately by the -9820' structure contour as shown page 3 on the enclosed Top West Fore]and structure map, Exhibit B. Additional drilling may further define the limits of accumulation. Analysis of a 30 foot by 4 inch conventional core taken between the intervals 1],574' to 11,604' from sands in the West Foreland Oil Pool in the Union, Trading Bay Unit, State G-19 well, gave the following porosity and permeability data: porosity varies from 5.9 to ]9.4 percent and averages ]5.7 percent. Permeability varies from 2.2 to ]89 millidarcys and averages 101.6 mi]]idarcys. The Union, Trading Bay Unit, State G-7 well was drill stem tested on 8/]5/68 (DST //2) from perforations 10,586 to 10,660 in the West Foreland Oil Pool. The test yielded an average f]o~v rate of 1540 BOPD, 31.6° APl Gravity, with 0.]% cut on a 32/64I' choke and pressure data as follows: IHP 5390#, IFP 2906#, ISIP 4498//, FHP 5352#, FFP 3875// and FSIP 4450//. As discussed above, the Middle Kenai .:'G" Oil Pool and the West Fore]and Oil Pool are separate and distinct pools from the previously defined Hemlock Oil Pool and Midclie Kenai Gas Pool. The stratigraphic separation of the Middle Kenai "G" and West Foreland Oil Pools support the applicant's request that these two pools be established as separate pools by Conservation Order, as p ropos e d.

ATTACH~vlENT F/G- 1 Geologic Character of Trading Bay Unit Oil Reservoirs NcArthur River Field Cook Inlet, Alaska Background In NcArthur River Field, water-injection has been successfully used to maintain reservoir pressure within the oil zones of the Tyonek Fm and the Hemlock Conglomerate as they have been gradually depleted by production. So doing has significantly enhanced the recovery efficiency in a manner which is environmentally safe. Reservoir engineering studies show that water should now be injected into the West Foreland Fm in order to maximize hydrocarbon recovery. Conclusions Virtually every hydrocarbon-bearing reservoir sand in ~cArthur River Field is isolated from those above and below by much finer-grained siltstones, coals, or tightly cemented layers. This is corroborated by significant reservoir pressure differences and a unique hydrocarbon/water interface within each zone. Further, within the Grayling Gas Sand interval, widely varying salinities, between adjacent sands with no clear relationship to depth, show that there can be no fluid communication between the very shallow fresher water (?) sands and the deep oil zones which themselves are much too saline to have any value as freshwater aquifers..The reservoir conditions of the West Foreland Fm are analogous to those of the overlying oil zones. By having maintained an excellent long-term performance history of environmentally safe water-injection programs in McArthur River Field, the operators have demonstrated that the same techniques can and should be applied to the West Foreland oil sands to ensure maximum recovery of producible hydrocarbons. Location NcArthur River Field, generally referred to as Tradinq Bay Unit, is located in Trading Bay on the west side of Cook Inlet, 22 miles ~orthwest from Kenai (Fig. 1). Rroduction from the field began in 1967 after three platforms were placed. From north to south they are the King Salmon, the Grayling, and the Dolly Varden. Structure The NoArthur River Field consists of two asymmetric, hydrocarbon-trapping structures. The largest one, called the "Main Feature", is a gently dipping, doubly plunging anticlinal fold with an axial trend generally NNE-SSW (see Figs. 2 through 4). It is separated from a smaller, related structure with similar reservoir development called the "Northwest Feature" by a small northeast-plunging syncline. The axis of the Northwest Feature, which extends NNW-SSE is truncated on the north end by the major NE-SW-trending Trading Bay Fault. The sense of displacement is down on the McArthur River Field side. For both anticlinal features the dip, slightly steeper on the west flank than on the east, ranges from approximately 5 to 17 degrees. McArthur River Field is not structurally complex. Besides the Trading Bay Fault already mentioned, there are three other down-to-the-south en echelon faults on the west side of the Main Feature. Of these, the Dolly Varden Fault, which is between the other two, has greatest offset and all three die-out to the southeast. .Strati~ra?h..¥ and Reservoir Description The productive zones of McArthur River Field are all nonmarine sediments of Tertiary age. They belong to the Kenai Group (Calderwood and Fackler, 1972) which is made up of five separate formations. In order of decreasing age, they are the West Foreland Fm, the Hemlock Conglomerate, the Tyonek Fm, the Beluga Fm and the Sterling Fm. Only the three oldest are represented in the rock record of ~cArthur River Field (see Fig. 5). Either the two youngest ones were never deposited or they were subsequently stripped away by erosion. They are, however, present in neighboring fields to the north and east. In the field area, the Kenai Group rests unconformably on rocks of Jurassic age which appear to be economic basement. West Foreland Fm: The Eocene West Foreland Fm is the oldest of the productive Tertiary units in Cook Inlet Basin. The uppermost part which contains the oil sands ranges in thickness from approximately 450 to 700 ft. It is an alluvial volcaniclastic unit with notable lithologic variability. The oil sands are intercalated with clay-rich siltstones, volcanic tuff layers and coal beds that limit vertical permeability. It appears that the West Foreland Fm was deposited very close to its source by low-gradient streams as indicated~by its poorly sorted texture and the large percentages of chemically unstable minerals and lithic fragments within the unit. The sequence of oil sands in the upper West Foreland Fm has been subdivided into six individual lobes or "benches" as a correlation tool within McArthur River Field. TBU G-?, which is the field "type log" (see Fig. 6) identifies each of the benches and shows the siltstone..or coal interbeds~between them. The average original oil accumulation limit for the WeSt Foreland Fm, at approximately lO,O00 ft subsea (see Fig. 7), is not common to the overlying units which clearly indicates that'it is a separate reservoir. This also implies that the finer-grained interbeds which separate the West Foreland Fm from the overlying Hemlock Conglomerate actas an effective vertical permeability.barrier. .The reservoir pressure within the WestForeland Fm averages 2990 psia at a'depth of 9650 ft subsea. The fact that this is lower, than the comparable pressure for the overlying reservoir further demonstrates that the two are separate fluid containers, . Hemlock Conolomerate: The major reservoir in McArthur River Field is the Hemlock Conolomerate of Oligocene age. It is markedly different from the West Foreland Fm which it unconformably overlies. Among the more distinguishing features are its clean texture and quartz-rich composition with fairly uniform cumulative thickness between 430 and 570 ft in the field area. It is dominated by coarse-grained sandstones and pebble conglomerates that are commonly interspersed with thin siltstone beds or tightly cemented impermeable layers. A well-developed system of braided streams of moderate energy that flowed into the trough from the northwest and from north to south along the basin axis appears to have been the major depositional mechanism during Hemlock time. Similar to the West Foreland Fm, seven sand benches are recognized within the Hemlock Conglomerate as an aid to reservoir analysis at McArthur River Field. Their typical expression is seen in TBU G-lC, the field "type log" for this unit (see Fig. 8). It has been shown by capillary pressure studies that variations in permeability exist within the Hemlock reservoir. As a result, the original oil/water interface is not quite level. This is reflected on the structure map (see Fig. 3) where it is shown to vary between 9675 and 9975 ft subsea. An average depth within this range is shown on the accompanying cross section A-A' (see Fig. 7). Because this is unique compared to the underlying and overlying units, it shows.they are not in fluid communication. As alluded to above, the average pressure within the Hemlock reservoir interval at 9350 ft subsea is 3940 psia. Compared to the adjacent units above and below, this value is considerably higher and shows this reservoir to be isolated from the others. ~yonek Fm: The thickest and youngest Tertiary rock unit present in McArthur River Field is the Tyonek Fm which straddles the Oligocene-Miocene age boundary. It is at least 9000 ft thick in the field area and consists of often blocky sandstones that alternate with siltstones and coals representing a monotonous, cyclic depostional pattern. This was the result of. low-energy streams which meandered across a broad floodplain leaving a record of bedload channel sands and upward-fining point-bar sequences, The siltstones typify interchannel and overbank deposits that provided a marshy substrate on which plant debris accumulate'd and gradually became coal. The coals of the Tyonek Fm tend to be thicker and much more persistent laterally than those of the adjacent formations, which makes them very useful correlation markers. Within the framework of the coal markers, it has become convenient to vertically subdivide the Tyonek Fm into zoneswhich have been named alphabetically within the field. The "A" Zone is the shallowest and the "G" Zone the deepest. Within the "A" through "D" Zones, an interval with an approximate thickness r~nging between 3050 and 3800 ft, there are 11 tested gas sands plus 17 more that are considered by log analysis to be capable of production. This whole interval is' called the "Grayling Gas Sands." Each sand exhibits unique rock and fluid properties and they all have separate gas/water interfaces as well. . At the base of the Tyonek Fm, which in some places may be transitional with the Hemlock Conglomerate, there is a sequence of six "G" Zone oil sands. They too behave as separate reservoirs quite different from the units above and below. TBU G-33 is the field "type log" for the "G" Zone oil sands, and Figure 9 shows the representative lithology. The approximate average original oil/water interface of the "G" Zone oil sands occurs at 8900 ft subsea (see Fig. 7). Again, this is sufficiently different from that of the Hemlock Conglomerate to demonstrate that a vertical permeability barrier exists between them. The unique average reservoir pressure of 2600 ps£a measured at 8850 ft subsea corroborates this observation. Subsurface Formation Water Content Investigations of formation water content over the years have relied quite heavily upon chemical analyses of fluid samples recovered during well testing. This approach, while fraught with uncertainty, was necessitated by a technological limitation. The tests were expensive which discouraged efforts to build a large enough database to be statistically reliable. It is also difficult to obtain uncontaminated samples as often as they could be used. In addition, one must be extremely confident that the test interval is completely isolated from adjacent zones~ When the sample is obtained. Because this is not always possible, reliability suffers. Fluid analysis reports, particularly from older wells, commonly fail to adequately identify the zone that was sampled. ~ ' Fortunately, computer techniques are now available to obtain statistically meaningful data and still circumvent many of the problems presented by analyzing what appears to be actual formation water. The electrical response of a formation that is continuously measured during logging operations is a function of the lithology and the contained fluid.. Unlike fluid samples, it is much easier to obtain rock samples at a known depth by taking cores during drilling. Through core analysis, it is possible to identify the electrical characteristics of the rock itself. The remainder can reasonably be inferred to result from the contained fluid. The salinity of the formation (in ppm equiValent NaC1) is just such a parameter. By comparing the icg responses within a given sand between all wells in a field such as McArthur River where a large number of wells (over 100) have been drilled, meaningful patterns in the data are discernible from statistical scatter. One. result of an intensive in-house'study of the Grayling Gas Sands 'was the identification of physical and electrical properties unique to each of these sands. From this study, it can be shown that the fluid salinity for each sand' in the Tyonek "A" through "D" Zone interval falls within a range between 6,900 and 68,650 ppm equivalent NaC1. For comparison, the salinity of normal seawater is approximately 35,000 ppm equivalent NaC1. It should also be noted that the salinity values for each sand are not predictably distributed with depth. . Within the Municipality of Anchorage, Alaska, the maximum allowable salinity for potable water is 500 ppm equivalent NaC1 and the salinity of naturally occurring groundwater is less than 5% of the upper limit. It should be clear that even as shallow as the Grayling Gas Sands in McArthur River Field, the naturally occurring formation waters are at least fourteen times more saline than the highest locally acceptable limit for potable water. In the McArthur River Field area, there are a few untested sands generally above 1~00 ft subsea, which appear from log analysis to contain fresher waters than are found in the deeper Grayling Gas Sands. Examples of these wells are the following: Depth at Base of Zone Well Measured Subsea Approx. Salinity Range Through Zone (ppm 6quiv NaCl) ARCO McArthur State ~1 1250 ft 1221 ft IBU K-1 1320 ft 1220 ft TBU G-4 1220ft 1121 ft 905 to 21,338 3142 to 34,821 2196 to 10,280 From the salinity data described above, it is obvious that fluid communication does not exist between the Grayling Gas Sands and the very shallow fresher water (?) sands close to the surface. Because each of the gas sands behaves as a separate reservoir, this entire interval represents multiple permeability barriers that effectively isolate the oil reservoirs several thousand feet deeper from the surface. The oll reservoirs themselves exhibit salinities within the same range as the Grayling Gas Sands and thus are in no way associated with freshwater aquifers. Water-Injection Prooram Maximizing hydrocarbon recovery requires that reservoir pressure not be allowed to fall below the bubble point (i.e., the pressure below which gas, normally in solution, will begin to evolve). A standard reservoir engineering practice is to inject water to replace produced hydrocarbons while simultaneously maintaining reservoir pressure within desired limits. This technique is very satisfactorywhere there is no fluid communication with freshwater aquifers. In so doing, it is important that the injection pressure be held below the threshold at'which artificial fracturing could occur to avoid inadvertently establishing communication between adjacent reservoirs where it would not normally exist. After. determining that formation waters within the producing reservoirs at McArthur River Field are far too deep and much toosaline to have any value as freshwater sources, a peripheral water-injection program was initiated within the Hemlock interval i~ May of 1968. Its success led to establishment of a similar program for the "G" Zone oil sands in November of 1973. From fracture stimulation treatments, estimates of a fracture gradient between 0.9 and 1.2 psi/ft have been confirmed. The current injection pressure of 3000 psi yields a fracture gradient of 0.77 psi/ft which assures a very safe margin well below the critical fracture pressure. . ,1. As predicted, there have been no environmental problems, such as contamination of freshwater zones resulting from water-injection to date. The effective long-term pressure maintenance and increased sweep efficiency of the "G" Zone and Hemlock oil reservoirs shows that the same technique applied to the West Foreland oil sands should also significantly extend their productive life without additional risk to the environment.

This testing includes, but is not limited to; drill stem tests and sample analyses, drilling pressure integrity tests (leakoff tests) to determine fracture gradient, injection tests and log analyses for physical rock properties and the presence of hydrocarbons. Information will continue to be collected on all production and injection zones located within the McArthur River Field, Trading Bay Unit boundary. Well logs will be: taken to Obtain additional information on the rock and fluid properties of the reservoir. As required by AOGCC, reservoir pressure will be monitored on a continuing basis over the extent of the injection/producing areas. In well's which have been fracture-stimulated, fracture extension pressures have varied from 0.85 psi/ft to 1.15 psi/ft, This equates to surface injection pressures from 3900 psi to 6750 psi. ATTACHMENT STIMULATION PROGRAM 40 CFR 146.24 (b) (2) Stimulation of Class II Injection Wells within the boundaries of the Trading Bay Unit may be performed; however, not on a routine basis. Stimulation may include acidization to treat damage and/or reperforation and possibly controlled fracturing to increase injectivity of the injection zone. In addition, small amount of fluid may be injected into various zones as a result of routine maintenance and stimulation. These operations may include: 1.) 2.) 4.) 7.) 8.) 9.) Acid treatments. Mud-acid treatments. Solvent washes. Corrosion inhibitor treatments. Fracturing stimulation. Diverting (plugging) agents. Well killing operations. Cement squeezes. Cement plugging.

Union Oil has and will continue to construct and convert all injection wells in accordance With the rules of the Alaska Oil & Gas Conservation Commission and Commission Order #80. All wells, both producers and injectors, are drilled and cased in essentially the same manner. All casing is cemented to assure no migration of formation fluids is possible. There will be some differences between wells regarding the size .of pipe used.and the depth at which the pipe is set. The difference between the types of wells is in the method of completion. Aproducing well is completed with gas lift mandrels in the tubing string. The injection wells are completed without gas'lift mandrels and with filtered inlet brine in the tubing-casing annulus. The brine used as annular fluid in some injection wells is treated with a corrosion inhibitor. Attachment L/M-1 provides information on a typical drilling program for the Trading Bay Unit.

Drilling Program: Pull 4-1/2" completion string from the existing G-22RD wellbore and kickoff at 5500' MD. Directionally drill 12-1/4" hole to top of G-Zone in the SW 1/4 of the NW 1/4 of Section 32, TgN, R13W (SM). A 9-5/8" casing string will be set and 8-1/2" hole will be drilled to TD with 7" liner to be set frbm ~750' MD to TD. Reason for Drilling: To provide a new injector that will increase the sweep efficiency for G-Zone and Hemlock reservoir sands On the Main Feature. It is expected that this well will enable recovery of at least 1,O00,O00 BO from the G-Zone plus 1,~O0,O00 BO from the .Hemlock that would not be produced from existing wells. Logging Program: DIL-BHC-GR-SP and CNL-LDT-GR-Cal from KOP to TD and CBL-VDL-GR inside 7" liner. Logs will be recorded on tape and film. A multishot gyroscopic survey will be run from surface to TD after casing is set. Coring Program: Sidewall samples may be obtained from intervals to beselected by electric log evaluation.

While at the well, the operator routinely checks the condition of controls, the annulus pressure and other well parameters. In case of a well failure where environmental impact is occurring at the surface as a result of such a well failure, spill prevention control and countermeasure (SRCC) plans are available on the platform. These documents provide information on the maximum quantities of fluids likely to be encountered ina spill,, flow direction of spilled liquids and other pertinent information necessary to control a spill. Also, an oil spill contingency plan is available, .which provides additional guidance on spill containment and clean-up procedures. In case of a well failure where below surface environmental impact is occurring as a result of such a well failure, all available data will be reviewed and the appropriate steps taken to eliminate the problem. Depending on the circumstances, actions such as pumping of "kill" weight fluid into the wellbore, setting of plugs in the wellbore, shutting in the well until repairs can be made, or other remedial actions will be performed.

Dear Mr. Johnston: TRADING BAY UNIT STATE OF ALASKA APPLICATION FOR AMENDMENT TO CONSERVATION ORDER NO. 80, RULE 2A Union Oil Company of California (Unocal), as Operator of the Trading Bay Unit and on behalf of the Working Interest Owners, request through the Oil and Gas Conservation Commission's Administration approval process to Amend Conservation Order No. 80, Rule 2A as follows' Rule #2A Casinq and Cementing Requirements' Surface casing shall be landed at a true vertical depth of not less than 1350 feet and cement shall be circulated to the seafloor. Casing and control equipment shall be hydrostatically tested to not less than 1000 pounds per square inch pressure before drilling the shoe. As you may recall, the AOGCC amended (May 12, 1988) C. O. #228 by adding Rule #4 as requested by Union. This Rule allows for an auxiliary casing string to be run above gas bearing sands when these sands exist above a true vertical depth of 2000', allOwing blowout prevention equipment to be installed. This Rule addition was made as a direct result of the Steelhead blowout and was meant, initially, as a proper means of drilling the relief well. Since that time, the Rule has led to Mr. David W. Johnston, Chairman February 7, 1991 Page 2 other problems in drilling the shallow gas production wells from the Steelhead platform. The specific problem is that the next string of casing after the auxiliary string is called surface casing and by AOGCC regulations, the surface casing cannot be produced through. The ultimate effect of Union's requested amendment would be to allow Marathon to properly case their shallow Steelhead wells, give the TBU owners more flexibility in well design for the other platforms and reduce the extra paperwork of additional amendments. In addition to the requested Rule change we also propose that Rule 4 of C.C. #228 be eliminated as being no longer necessary. Your favorable consideration of the application is requested.

Very truly yours; ............ Wayn~/Rodges Enclosure TWELVETH SEMIANNUAL PROGRESS REPORT TO THE STATE OF ALASKA OIL AND GAS CONSERVATION COMMITTEE CONSERVATION ORDER NO. 80 PRESSURE MAINTENANCE PROJECT McARTHUR RIVER FIELD - HEMLOCK OIL POOL DATA TO JANUARY 1, 1975 Prepared by: TRADING BAY UNIT - ENGINEERING & PLANNING GROUP INTRODUCTION In compliance with Conservation Order No. 80, Rule No. 4, this Twelveth Semiannual Progress Report is submitted to the State of Alaska Oil and Gas Conservation Committee. PROJECT OPERATIONS One Hemlock producing well, G-21, has been completed since the last progress report. Two producing wells, D-8 and D-14, have been redrilled to u~structure locations and one producing well, K-4, has been sidetracked during the same period of time. One producing well, G-16, has been con- verted to water injection. As of the date of this report, there are 43 producing wells, 2 inactive wells and 17 injection wells completed in the Hemlock Reservoir. Currently, one injection well, D-24A, is being drilled to replace an injector, D-24, which was abandoned with collapsed casing. A Hemlock producing well, G-23, is being drilled at an upstructure location on the main geologic feature. A co-mingled "G" Zone and Hemlock producing well, K-10, has been abandoned and is being redrilled to a more productive location on the crestal portion of the NW feature of the reservoir. RESULTS From the start of the project to January 1, 1975, cumulative withdrawls of oil, gas and Water were 240,393,443 stock tank barrels or 282,710,619 reservoir barrels. Cumulative injection has been 281,994,541 barrels or 99.7 percent of reservoir withdrawals. The latest estimated average pressure is reflected in the attached exhibits. The attached Exhibit I depicts the best current estimate of reservoir pressure as a function of cumulative oil production. Exhibit II depicts production rate and average reservoir pressure versus time. Exhibit III summarizes pertinent data as of January 1, 1975. Exhibit IV summarizes the last 12 months production and injection data. Exhibit V is a structure map drawn on top of the Hemlock. :; :. · ..:: :: : , · ., i ; ' .
