Atlantic Richfield Company, as operator of the North Trading Bay Unit, submitted an application dated November 5, 1971 for exception to Rule 3 of Conservation Order No. 69 which permits a maximum of two completed oil wells per governmental quarter section in the referenced pools and for exception to Title 11, Alaska Administrative Code, Section 2061 (b) which, among other requirements, stipulates a minimum distance of 1000 feet between wells producing from the same pool, for the North Trading Bay Unit No. S-8 well. For the same well, the Atlantic Richfield Company anticipates a second completion in~the West Foreland Formation, which is not unitized and not a de- fined oil pool, requiring an exception to Title 11, Alaska Administrative Code, Sec- tion 2061 (b) which, among other requirements, stipulates a minimum distance of 500 feet to a property line where ownership changes. 2. The North Trading Bay Unit No. S-8 directional well will penetrate the referenced unitized pools near the southwest corner of Section 26, T. 10 N., R. 13 W., S.M. and the West Foreland Formation in the northeast corner of Section 34, T. 10 N., R. 13 W., S.M. 3. Notice of the hearing was published in the Anchorage Daily News on November 17, 1971. A typographical error resulted in the notice reading "Section 2961" in the fourth line instead of the correct "Section 2061." There were no protests to the notice. FINDINGS: 1. All of the production from the Trading Bay "G" NE and Trading Bay Hemlock NE Oil Pools has been unitized within the area of the North Trading Bay Unit and the correla- tive rights of all affected parties are protected. 2. A pressure maintenance project has been approved for the referenced pools within the North Trading Bay Unit. 3. The completion in the defined pools will be at an optimum structural position and should increase the ultimate recovery of oil. #- , -) i ) Conservation Order No. 110 Page 2 November 30, 1971 4. The operator anticipates a second completion in the Hest Foreland Formation at an optimum structural position which may develop additional primary reserves. 5. The referenced well should intersect the West Foreland Formation on lease ADL 17597, jointly owned by Texaco Inc. and the Superior Oil Company, and adequate provi- sions for the protection of correlative rights are required. CONCLUSION: The increase in ultimate recovery from the referenced pools and the possible de~ velopment of additional primary reserves are adequate for exceptions to permit the drilling of this well, and a completion in the West Foreland Formation should be al~ lowed if the correlative rights of all affected parties are adequately protected. NOW, THEREFORE, IT IS ORDERED THAT: 1. The Atlantic Richfield Company be 'permitted to drill the North Trading Bay Unit No. S-8 well to a bottom hole location near the northeast corner of Section 34, T. 10 N., R. 13 W., S.M. and to complete the well in the defined pools. 2. The completion of the North Trading Bay Unit No. S-8 well in the Hest Foreland Formation is approved, subject to receipt of evidence that the correlative rights of all ~ffected parties will be protected.

The proposed bottom hole location is near the NE corner of Section 34, T. 10 N., R. 13 'v., S.M. Notice is hereby given that the Atlantic Richfield Company has petitioned the Alaska Oil and Gas Conservation Committee for an order to permit the drilling and dual completion of the North Trading Bay Unit S-8 well. The oil completion in the Trading Bay "G" NE Oil Pool and the Trading Bay Hemlock NE Oil Pool requires an exception to Rule 3 of Conservation Order No. 69 which permits a maximum of two completed oil wells per governmental quarter section and Section 2061 (b) of the Oil and Gas Conservation Regulations which requires a minimum distance of 1000 feet between wells producing from the same pool. An oil completion below the intervals of the defined pools at the proposed location requires an exception to Section 2061 (b) of the Oil and Gas Conservation Regulations which requires a minimum distance of 500 feet from a lease line where ownership changes. The applicant states that the proposed well is anticipated to develop production in each completion interval at optimum structural positions and should increase the ultimate recovery of oil. Pursuant to Title 11, Alaska Administrative Code, Section 2009, parties who may be aggrieved if the requested order is issued are allowed 10 days from the date of this publication in which to file a protest and request for hearing.

(Exhibit I). This proposed well will require an exception to Rule 3 of Conservation Order #69, dated January 24, 1969, and an exception to the provisions of Item (b) of Section 2061 of the State of Alaska Oil and Gas Conservation Regulations. Rule 3 of Conser- vation Order #69 established an 80-acre well spacing for the Trading Bay Field "G" and Hemlock Northeast Oil Pools. Item (b) of Section 2061 of the State of Alaska Oil and Gas Conservation Regulations established a minimum distance between oil wells, drilling to or capable of producing from the same oil pool, of 1,000 feet. The proposed S-8 well will include within its com- pleted interval the Trading Bay Field "G" and Hemlock Northeast Oil Pool's sections and will be located, at the top of the Hemlock Pool, with respect to adjacent Trading Bay Field "G" and Hemlock Northeast Oil Pool's completed wells, approximate distances as follows: 950 feet from well S-l, 730 feet from well S-2, 950 feet from well TS-l, and 900 feet from well TS-3RD. The attached Exhibit I, a plat drawn to a scale of one inch equaling 500 feet and showing the structure of the Trading Bay Field Hemlock North- east Oil Pool, shows the location of all wells on the property and the well course and bottom hole location of the proposed S-8 well. It is anticipated that the proposed well will develop at a crestal location the Trading Bay Field "G"-Producing and Hemlock Northeast Oil Pools and a deeper, undrained West Forelands oil sand.

The attached Exhibit III, the dual induction laterolog of the Atlantic Richfield Company TBS #1 which is located in Section 26, TION, R13W, S.M., further depicts these objective horizons at this location. The entire producing area of the Trading Bay Field "G" and Hemlock Northeast Oil Pools has been unitized by the North Trading Bay Unit as of an effective date of July 1, 19710 The "G" and Hemlock formation of the unitized land is defined as the stratigraphic equivalent of that occurring between the dual induction laterolog depths of 8,818 feet and 10,174 feet in the Atlantic Richfield Company TBS #1 well (see the attached Exhibit III), as described in Section 3 of the Unit Agreement (For the Development and Operation of the Hemlock and "G" Formation, North Trading Bay Unit Area, State of Alaska) dated June 1, 1971. All correlative rights and equities of the a.ffected interest owners are adequately protected through this unitization and the applicable provisions thereof and of the Unit Operating Agreement (Hemlock and "G" Formations, North Trading Bay Unit, Cook Inlet, Alaska). Property and lease boundary lines within the unit are subject to the philosophy of unitization and may be disregarded for the purpose of drilling the proposed well in the "G" and Hemlock formations as described by that certain Unit Agreement. The further objective of the proposed well is for an oil productive completion within a West Forelands sand that is located between 10,448 feet and 10,484 feet in the Atlantic Richfield Company TBS #1 well (see attached Exhibit III). The entire West Forelands section, and deeper horizons, are not included within the North Trading Bay unitized interval and as such, completion of the proposed well within any sands comprising this interval, at a location in the immediate vicinity of the northeast corner of Section 34, TION, R13W, S.M., is not subject to the philosophy of unitization. As a consequence, the North Trading Bay Unit participants, Atlantic Richfield Company, Texaco Inc., and The Superior Oil Company, are executing an appropriate joint linewell agreement to protect correlative rights of the affected interest owners and to establish equities in the West Forelands oil production. Texaco Inc. and The Superior Oil Company will each furnish a letter of nonobjection to the proposed well. There are no affected operators other than the North Trading Bay Unit participants listed above, each of whom is receiving a copy of this exception application. The anticipated completion of the proposed S-8 well in the "G"- Producing,Hem10ck, and West Forelands intervals will produce from State of Alaska Leases ADL 35431, ADL 18776, and ADL 17597. By letter of October 28, 1971, the State of Alaska, Division of Lands, has been advised of our intention to drill the S-8 well. Atlantic Richfield is negotiating with the Division of Lands a method of allocating production from the non-unitized zone to the affected leases ADL 35431, ADL 18776, and ADL 17597. We have also requested that the Division of Lands furnish a letter of nonobjection. ) ) Alaska Oi~ and Gas Conservation Committee Page 3 November 5, 1971 In support of this application, Atlantic Richfield Company, as Unit Operator, respectfully submits the following reports and exhibits: 1. Geologic and Engineering Report. 2. Exhibit I, a structural contour map showing the top of the Hemlock Pool and the location of the proposed well, S-8. 3. Exhibit II showing schematically the geologic cross- section through well S-8 at the objective sands levels. 4. Exhibit III, the dual induction laterolog of the Atlantic Richfield Company TBS #1 well showing the objective sands for development by the proposed well S-8 at the TBS #1 well location. 50 Exhibit IV, a structural contour map showing the top of the West Forelands section and the location of the proposed well, 8-8. Now, therefore, Atlantic Richfield Company, on behalf of the aforementioned Unit participants, hereby respectfully requests that an order be issued for the purpose of granting exception to Rule 3 of Conservation Order #69, and to Item (b) of Section 2061 of the state of Alaska Oil and Gas Conservation Regulations, thereby authorizing the drilling of the proposed S-8 well at the proposed location described herein. If no objection to the granting of these exceptions is received pursuant to Section 2009 of the State of Alaska Oil and Gas Conservation Regulations, we request that this exception be granted without the necessity of a hearing. If protest is received, we ask that the matter be set for hearing at the earliest convenient date. This application for exception is for well S-8 only.

This proposed well, to be drilled into unitized lands from the Atlantic Richfield Company-owned Platform Spark, will have a bottom-hole location in the immediate vicinity of the northeast corner of Section 34, TION, R13W, S.M. Drilling and completion of the herein proposed well requires an exception to the 80-acre spacing per producing well established by Rule 3 of Conservation Order No. 69 and an exception to the 1,000 feet minimum distance between producing wells in the same pool, as specified by Item (b), Section 2061 of the State of Alaska Conservation Regulations. The proposed well will be located at the top of the Hemlock Pool, with respect to adjacent North Trading Bay Unit "G" and Hemlock completed wells, approximate distances as follows: 950 feet from well S-l, 730 feet from well S-2, 950 feet from well TS-l, and 900 feet from well TS-3RD (Exhibit I). This request for spacing and minimum distance exceptions is for well S-8 only. In support of this application for exception, we respectfully attach the following exhibits: 1. Exhibit I, a structural contour map showing the top of the Hemlock Pool and the location of the proposed well, S-8. 2. Exhibit II, a schematic geologic cross-section through well S-8 at the objective sand levels. 3. Exhibit III, the dual induction laterolog of the Atlantic Richfield Company TBS #1 well showing the objective sands for development by the proposed well S-8 at the TBS #1 well location. 4. Exhibit IV, a structural contour map showing the top of the West Forelands section and the location of the proposed well S-8. The proposed S-8 producing well will be drilled to develop the following intervals: a. The currently producing "G"-Producing and Hemlock interval identified as that interval between 9,660 feet and 10,090 feet at the Atlantic Richfield Company TBS #l well location (Exhibit III). ) GEOLOGIC AND ENGINEER1~G REPORT Fage 2 ) b. The basal Hemlock sand that is not currently completed in any of the North Trading Bay Unit wells and is identified as that interval between 10,090 feet and 10,174 feet at the TBS #1 well location (Exhibit III). c. The objective West Forelands sand that has been penetrated only by the abandoned TBS #1 well at the North Trading Bay Unit, and is identified at this well location as that interval between 10,448 feet and 10,484 feet. d. Possible sand(s) below the. objective West Forelands sand described above. structural contour maps drawn on the top of the Hemlock interval and on the top of the West Forelands section are shown by Exhibits I and IV, respectively. Exhibit II, the schematic geologic cross-section, illustrates the location of the objective horizon to be developed by the proposed S-8 well. Both the currently producing "G"-Producing and Hemlock interval and the basal Hemlock sand objectives of the proposed well are a part of the unitized interval of the North Trading Bay Unit. The North Trading Bay Unit became effective on July 1, 1971, and the unitized interval is defined as the stratigraphic equiva- lent of that occurring between the dual induction laterolog depths of 8,818 feet and 10,174 feet in the Atlantic Richfield Company TBS #1 well (Exhibit III). The objective West Forelands sand and deeper sands are not included in the unitized interval of the North Trading Bay Unit. As a consequence, the North Trading Bay Unit participants, Atlantic Richfield Company, Texaco Inc., and The Superior Oil Company, the only affected parties, are executing an appropriate joint linewell agreement to protect correlative rights and to establish equities in oil production and reserves from the objective West Forelands sand and deeper sands. The anticipated completion of the proposed S-8 well in the "G"-Producing, Hemlock, and West Forelands intervals will produce from State of Alaska Leases ADL 35431, ADL 18776, and ADL 17597 (Exhibit I). By letter dated October 28, 1971, the State of Alaska, Division of Lands has been advised of our intention to drill the S-8 well. Atlantic Richfield Company is negotiating with the Division of Lands a method of allocating production from the non-unitized interval in the proposed well to the affected leases ADL 35431, ADL 18776, and ADL 17597. GEOLOGIC AND ENGINEERING REPORT The anticlinal structure of the Trading Bay Field Northeast Oil Pool is illus- trated in Exhibits I and IV. The structure is described as a slightly asymmetrical anticline with an axis trending approximately N 5° .E and separated in the west by a steep, narrow syncline from an adjacent structural system. A north- south lease line separating Texaco-Superior Lease ADL 17597 from Atlantic Richfield Company Leases ADL 35431 and ADL 18776 runs approximately along the anticlinal crest of the structure (Exhibit I and Exhibit IV). The structure is indicated to be a simple unfaulted one as shown on Exhibit II, the schematic geologic cross-section along the proposed 8-8 well course. As is seen on Exhibit II, stratigraphic layers have a general field-wide uniformity in thickness as is also indicated by the similarity in the two structural maps, Exhibits I and IV. ) GEOLOGIC AND ENGINEER1~G REPORT Page 3 ) Exhibit III depicts the currently producing strata at the North Trading Bay Unit which are the "G"-Producing and Hemlock producing intervals from 9,660 feet to 10,090 feet in the TBS #1 well. The basal Hemlock bed between 10,090 feet and 10,174 feet in the TBS #1 well (Exhibit III) is not completed in any of the North Trading Bay Unit wells. Exhibit III also identifies the objective West Forelands bed between 10,448 feet and 10,484 feet in the TBS #1 well. Well TBS #1 is located downstructure on the east flank of the anticline. It is believed that there is a downstructure deterioration of reservoir quality at the North Trading Bay Unit as is common in other Cook Inlet producing fields. The original oil-water contacts in the "a"-Producing and Hemlock intervals are shown on Exhibit II and are at approximately - 9,700 feet in the "G"- Prodùcing interval and at - 9,900 feet in the Hemlock interval. The oil-water contact in the objective West Forelands sand is estimated to be at - 10,420 feet. The primary development of the Trading Bay Field Northeast Oil Pools has been from the Texaco-Superior Platform A and the Atlantic Richfield Company Platform Spark (Exhibit I) and was conducted prior to the formation of the North Trading Bay Unit on July 1, 1971. The field was developed according to Conservation Order No. 69 which permits no more than two completed oil wells per governmental quarter-section and according to Item (b), Section 2061 of the State of Alaska Oil and Gas Conservation Regulations which prohibits the bottom-hole location of pay opened to the wellbore closer than 500 feet to any property line. Because of these spacing regulations and the orientation of the structure in relation to the lease line separating the Texaco-Superior lease from the Atlantic Richfield Company leases, there have been no wells drilled into the crest of the anticlinal structure. All development wells have been completed downstructure as shown on Exhibits I and IV. As a consequence of this and the location of the original oil-water contact in the Hemlock interval, completion of a well in a full oil productive Hemlock section has not been possible. In addition, and because of the probable downstructure deterioration of the reser- voir rock quality, the objective West Forelands sand interval has not been tested at a structurally optimum location. Effective July 1, 1971, the North Trading Bay Unit was formed. The prime intent of the formation of this unit was to provide for the secondary development of the Trading Bay Field "G" and Hemlock Northeast Oil Pools through a water injection pressure maintenance program. It is planned to inject water into the total "G" -Product i ve and Hemlock intervals to improve the ul t'imate oil recovery from these intervals. Currently Producing "G"-Producing and Hemlock Intervals The proposed S-8 well will improve the secondary recovery sweep efficiency and thereby the ultimate oil recovery and will accelerate the oil recovery from the "G"-Producing and Hemlock intervals. Basal Hemlock Sand The proposed S-8 well will be completed at the structurally optimum point, the anticlinal crest, of the basal Hemlock sand as shown on Exhibits I and II. This sand was fully penetrated by North Trading Bay Unit wells TBS #1, S-l, S-2, S-3, S-4, S-5, TS-3RD, and TS-6 but was found wet or partially wet at all ) GEOLOGIC AND ENGINEERING REPORT Page 4 ') of these downstructure locations. The sand has never been completed at the North Trading Bay Unit. The proposed S-8 well is expected to develop a full oil-bearing section in this sando It is planned to complete the basal Hemlock sand at two currently existing downstructure locations for water injection. Consequently the proposed basal Hemlock sand completion in well S-8 will develop new primary and secondary oil reserves. Objective West Forelands Sand This sand has been drill-stem tested poorly productive in the downstructure abandoned TBS #1 well. Exhibit III details this drill-stem test data. The bed has not been penetrated elsewhere in the North Trading Bay Unit. It is anti- cipated that at the crestal location the proposed S-8 well will develop a full productive oil column in this sand and thereby develop new primary oil reserves. Possible Deep Sands The proposed S-8 well may be drilled up to 700 vertical feet below the objective West Forelands sand, depending upon information obtained from the wells' logs, to test for further oil bearing's,and development. The additional 700 vertical feet represent approximately 500 structural feet deeper than has pre- viously been drilled at the North Trading Bay Unit. We anticipate that with a successful development of West Forelands sand(s) at the proposed S-8 well location, the optimum well completion will be one where the oil from the "G"-Producing and Hemlock formations will be commingled in the wellbore with the oil from the West Forelands sand(s). It is believed that such a compJe t ion will not reduce the ultimate recovery from any of the intervals. In addition, the well completion will permit separate production rate measure- ments of the individual intervals. We are planning to apply for an exception to Section 2154 of the State of Alaska Oil and Gas Conservation Regulations at a later date to permit wellbore commingling of production from the "G"-Producing and Hemlock interval with production from the West Forelands formation of the proposed S-8 wello SUMMARY The location of the current North Trading Bay Unit wells, with all of the wells completed off the crest of the north-south oriented anticline, has prohibited an oil productive completion in the basal Hemlock sand. The high structural position of the proposed S-8 well will permit an oil productive completion in the basal Hemlock sand and will also permit the testing of the objective West Forelands sand and possible deeper sands at the optimum location. The proposed S-8 well will accelerate the oil recovery from the HGH and Hemlock intervals currently produced, develop new waterflood reserves in these intervals, and develop new reserves in the basal Hemlock sand. The proposed well is also expected to develop new reserves in the West Forelands section. u.~ '0 X 10 TO THE INCH 46 0782 n ¡:;;, 7 X 10 INCHES "AO~IN U.S.A, .
