By letter dated February 3, 2025, Hilcorp Alaska, LLC (Hilcorp), in its capacity as operator of the Tyonek Undefined Gas Pool in the former Sterling Unit (SU) requests an order approving an exception to the spacing requirement of 20 AAC 25.055 to drill, test, and operate as a gas development well the proposed Sterling Unit 43-10 (SU 43-10) well in the Tyonek Undefined Gas Pool within 1,500 feet of property lines where ownership or landownership change. 2. In accordance with 20 AAC 25.055(d), Hilcorp sent, by certified mail, notice of the application to all owners, landowners, and operators of all properties within 3,000 feet of the SU 43-10 well and provided the notice, addresses to which the notices were delivered, and certified mail receipts to the AOGCC. 3. Pursuant to 20 AAC 25.540, the AOGCC scheduled a tentative public hearing for March 13, 2025. On February 5, 2025, the AOGCC published notice of the hearing on the State of Alaska’s Online Public Notices website, the AOGCC’s website, and the AOGCC electronically transmitted the notice to all persons on the AOGCC’s email distribution list. On February 9, 2025, the notice was published in the ANCHORAGE DAILY NEWS. 4. The AOGCC received no comments or requests to hold the proposed hearing. The scheduled hearing was vacated. 5. Hilcorp’s application, additional information submitted by Hilcorp, AOGCC’s records, and publicly available information are sufficient to make an informed decision. PURPOSE AND NEED FOR THIS ORDER: Well spacing regulations protect the oil and gas rights of adjacent landowners and maximize resource recovery by establishing default limits on how close, under the land's surface, oil and gas wells can be to property lines where ownership changes. These limits are set forth in Regulation 20 AAC 25.055. Operators must abide by the default well spacing limits (referred to as statewide spacing requirements) unless they apply for, and obtain, an exception to those limits. Although exceptions to the default well spacing requirements are not unusual, AOGCC carefully evaluates each application, and typically grants them only when actual geologic conditions demonstrate that the proposed subsurface location of a well is necessary to reach otherwise unreachable oil or gas, Conservation Order 826 July 16, 2025 Page 2 of 5 the rights of adjacent landowners are upheld, and underground sources of drinking water can be protected. As a general matter, AOGCC does not have extensive authority over surface impacts such as noise, emissions, or construction. FINDINGS: 1. Sterling Unit History: The SU, comprising 2,760 acres, was approved as a federal oil and gas unit on July 7, 1961. Discovered and first tested by exploratory well Sterling Unit 23-15 in 1961 and 1962, the six wells drilled and completed within the unit produced a total of 14,466,724,000 cubic feet of natural gas between May 1962 and April 2015 from the following Undefined Gas Pools (in descending stratigraphic order): Sterling, Upper Beluga, Beluga, Lower Beluga/Tyonek, and Tyonek. In 2013, Hilcorp was designated operator for this unit. Since May 2015, wells within SU have not produced paying quantities of any unitized substance. Accordingly, on December 15, 2017, the Federal Sterling Unit Agreement (AA050887) was terminated by the U.S. Bureau of Land Management.1 2. Owners: Affected landowners are Cook Inlet Region, Inc. (CIRI), the State of Alaska (SOA), Alaska Mental Health Trust Authority (MHTA), and private entities for the properties traversed by, or within 1,500 feet of, the proposed SU 43-10 well path. CIRI is landowner for lease C- 061723, which contains the proposed surface and target locations. The proposed well traverses a portion of MHTA lease 9300101, and the proposed bottom-hole location lies near the boundary of lease 9300101 and in SOA lease ADL 394293. Hilcorp is 100% working interest owner for all tracts within 1,500’ of SU 43-10. 3. Operator: Hilcorp is Operator for this proposed onshore gas development well, which is located within Kenai Peninsula Borough on the east side of the Cook Inlet Basin and about 3 miles northeast of Soldotna, Alaska. 4. Well Location: The proposed SU 43-10 well, shown in Figure 1 below, will be located as follows. Surface Location: 2327' FSL, 526' FEL, Section 9, T5N, R10W, Seward Meridian (SM) Target Location (Estimated): 1706' FSL, 1187’ FWL, Section 10, T5N, R10W, SM Bottom Hole Location: 900' FSL, 1754’ FEL, Section 10, T5N, R10W, SM 5. Governing Well-Spacing Rule: Regulation 20 AAC 25.055(a)(2) governs well spacing for the undefined gas pools within the former SU. Portions of proposed well SU 43-10 will lie within 1,500’ of property lines where ownership and / or landownership changes. 6. Exception Justification: SU 43-10 targets unproven reserves in the Tyonek Undefined Gas Pool. These reserves cannot be reached and efficiently developed by conforming to applicable statewide spacing regulations because of the narrow, discontinuous, and lenticular nature of the Tyonek reservoir sands and their most prospective locations on the subsurface structure. 1 U.S. Bureau of Land Management, Alaska State Office, Decision: Federal Oil and Gas Unit Terminated, Leases Extended, dated April 10, 2018. Conservation Order 826 July 16, 2025 Page 3 of 5 Figure 1. Map of Planned Hilcorp SU 43-10 Wellbore Displaying the 1,500’ and 3,000’ Buffers Surrounding the Proposed Well Path (Source: Hilcorp Alaska, LLC) Conservation Order 826 July 16, 2025 Page 4 of 5 7. Freshwater Protection and Waste Prevention: If conducted as required, drilling, completion, testing, and operation of SU 43-10 will not cause waste or result in an increased risk of fluid movement into freshwater. 8. No Conflict of Ethics Act Determination: AOGCC Commissioner Wilson is surface owner of a property that lies within 1,500’ of the proposed well SU 43-10. Commissioner Wilson is not a mineral rights owner, has no financial interest in Hilcorp’s proposed well, and does not have a personal relationship with any of the mineral rights owners potentially affected by Hilcorp’s proposed activities. In response to Commissioner Wilson’s Ethics Supervisor Determination Form, the Office of Governor in consultation with the Department of Law determined that there is not an Ethics Act conflict that would restrict participation in this matter and confirmed that “this does not or would not violate AS 39.52.110-.190.” Copies of that form, a property location map, and the Ethics Act Determination are included in the record for this decision. CONCLUSIONS: 1. An exception to the well spacing provisions of 20 AAC 25.055 is necessary to allow drilling, completion, testing, and operation of SU 43-10 as a gas development well within the Tyonek Undefined Gas Pool. 2. It is unlikely that a well conforming to the spacing provisions of 20 AAC 25.055 would be able to access and efficiently produce the targeted reservoir sands. 3. If constructed and operated as required, SU 43-10 will not cause waste or result in an increased risk of fluid movement into freshwater. 4. Correlative rights of landowners of any uncommitted tracts that lie more than 1,500’ from SU 43-10 will be protected by adhering to the well spacing requirements of 20 AAC 25.055. 5. Granting an exception to the well spacing provisions of 20 AAC 25.055 will not result in waste or jeopardize correlative rights of adjoining or nearby owners, is based on sound engineering and geoscience principles, and will not result in an increased risk of fluid movement into freshwater. 6. The Office of Governor, in consultation with the Department of Law, determined that Commissioner Wilson has no Ethics Act conflicts that would restrict participation in this matter. NOW, THEREFORE, IT IS ORDERED: The AOGCC grants Hilcorp’s February 3, 2025, application for an exception to the well spacing provisions of Regulation 20 AAC 25.055(a)(2) to allow the drilling, completion, testing, and operation of SU 43-10 as a gas development well in the Tyonek Undefined Gas Pool. Hilcorp may proceed and must comply with all applicable laws and all other legal requirements. Conservation Order 826 July 16, 2025 Page 5 of 5 DONE at Anchorage, Alaska and dated July 16, 2025. Jessie L. Chmielowski Gregory C. Wilson Commissioner Commissioner RECONSIDERATION AND APPEAL NOTICE As provided in AS 31.05.080(a), within 20 days after written notice of the entry of this order or decision, or such further time as the AOGCC grants for good cause shown, a person affected by it may file with the AOGCC an application for reconsideration of the matter determined by it. If the notice was mailed, then the period of time shall be 23 days. An application for reconsideration must set out the respect in which the order or decision is believed to be erroneous. The AOGCC shall grant or refuse the application for reconsideration in whole or in part within 10 days after it is filed. Failure to act on it within 10-days is a denial of reconsideration. If the AOGCC denies reconsideration, upon denial, this order or decision and the denial of reconsideration are FINAL and may be appealed to superior court. The appeal MUST be filed within 33 days after the date on which the AOGCC mails, OR 30 days if the AOGCC otherwise distributes, the order or decision denying reconsideration, UNLESS the denial is by inaction, in which case the appeal MUST be filed within 40 days after the date on which the application for reconsideration was filed. If the AOGCC grants an application for reconsideration, this order or decision does not become final. Rather, the order or decision on reconsideration will be the FINAL order or decision of the AOGCC, and it may be appealed to superior court. That appeal MUST be filed within 33 days after the date on which the AOGCC mails, OR 30 days if the AOGCC otherwise distributes, the order or decision on reconsideration. In computing a period of time above, the date of the event or default after which the designated period begins to run is not included in the period; the last day of the period is included, unless it falls on a weekend or state holiday, in which event the period runs until 5:00 p.m. on the next day that does not fall on a weekend or state holiday.

BACKGROUND INFORMATION On February 4, 2025, Hilcorp applied for an exception to 20 AAC 25.055(a)(2) to drill, complete, test, and operate the SU 43-10 gas development well in the Tyonek Undefined Gas Pool. The Tyonek Formation was specified as the intended target within 1,500’ of property lines where the owners or landowners are not the same on both sides of the line. Notification of affected owners, landowners, operators, and the public was conducted in accordance with 20 AAC 25.055 and 20 AAC 25.540 and a public hearing was tentatively scheduled. No comments or requests for the tentatively scheduled public hearing were received, and that hearing was vacated. On July 16, 2025, AOGCC issued CO 826 granting an exception to 20 AAC 25.055(a)(2) allowing Hilcorp to drill, complete, test, and operate SU 43-10 in the Tyonek Undefined Gas Pool. 1 Although well names in this area historically include the terms “Sterling Unit” or “SU”, this may cause some confusion. On December 15, 2017, the Federal Sterling Unit Agreement (AA050887) was terminated by the U.S. Bureau of Land Management. Accordingly, the Sterling Unit no longer exists as a formal entity. However, existing and proposed well names that include the terms “Sterling Unit” or “SU” are retained by AOGCC because, under Regulation 20 AAC 25.005(f), each well is identified by a unique name designated by the operator. See also U.S. Bureau of Land Management, Alaska State Office, Decision: Federal Oil and Gas Unit Terminated, Leases Extended, dated April 10, 2018. CO 826.001 December 10, 2025 Page 2 of 5 CURRENT APPLICATION Hilcorp’s application requests AOGCC expand vertically the spacing exception granted in CO 826 to include shallower geologic strata. In accordance with 20 AAC 25.055(d), Hilcorp sent by certified mail notice of their October 6, 2025 application to all owners, landowners, and operators of all properties within 3,000 feet of the SU 43-10 well. Hilcorp provided AOGCC copies of the notices and addresses to which the notices were delivered. No comments or requests for public hearing have been received in response to Hilcorp’s current notice to amend CO 826. Hilcorp’s only requested change is to amend the restriction in CO 826 that limits completing, testing, and operation of SU 43-10 to the Tyonek Undefined Gas Pool. This application to extend CO 826 does not require granting a new exception to the spacing regulation, which necessitates tentatively scheduling a public hearing. Rather, it only seeks to remove a restriction included in CO 826. Therefore, 20 AAC 25.556(d) allows the AOGCC to administratively amend CO 826 without a hearing in this instance. Hilcorp’s application, additional information submitted by Hilcorp, AOGCC’s records, and publicly available information are sufficient to make an informed decision. PURPOSE AND NEED FOR THIS ORDER Well spacing regulations protect the oil and oil rights of adjacent landowners and maximize resource recovery by establishing default limits on how close, under the land's surface, oil and gas wells can be to each other and to property lines where ownership changes hands. These limits are set forth in a regulation 20 AAC 25.055. Operators must abide by the default well spacing limits (referred to as spacing requirements) unless they apply for, and obtain, an exception to those limits. Although exceptions to the default well spacing requirements are not unusual, AOGCC carefully evaluates each application, and typically grants them only when actual geologic conditions demonstrate that the proposed subsurface location of a well is necessary to reach otherwise unreachable oil or gas, the rights of both adjacent landowners are upheld, and underground drinking water can be protected. As a general matter, AOGCC does not have extensive authority over surface impacts such as noise, emissions, or construction. FINDINGS SU 43-10 will be located as follows (unchanged from CO 826; see Figure 1, below). Surface Location: 2327' FSL, 526' FEL, Section 9, T5N, R10W, Seward Meridian (SM) Target Location (Estimated): 1706' FSL, 1187’ FWL, Section 10, T5N, R10W, SM Bottom Hole Location: 900' FSL, 1754’ FEL, Section 10, T5N, R10W, SM Hilcorp requests AOGCC amend CO 826 to include potential reserves that may be encountered at depths shallower than the Tyonek Undefined Gas Pool. Natural gas may have accumulated in undefined pools within the following additional overlying geologic strata (in descending depth order): Sterling, Upper Beluga, Beluga, and Lower Beluga/Tyonek. These potential gas reserves CO 826.001 December 10, 2025 Page 3 of 5 were omitted in Hilcorp’s previous application and accordingly are not currently included in CO 826. Hilcorp seeks to amend CO 826 only to include those additional, shallower strata. No other changes or additions are proposed. Figure 1. Map of Planned Hilcorp SU 43-10 Well Displaying the Proposed Well Path and 1,500-Foot Buffer. (Source: Modified from Hilcorp Alaska, LLC) CO 826.001 December 10, 2025 Page 4 of 5 Regulation 20 AAC 25.055(a)(2) governs well spacing for the undefined gas pools within the Sterling Gas Field. Figure 1 depicts the proposed SU 43-10 well path. The solid red boundary represents the 1,500’ buffer surrounding the well that is specified in 20 AAC 25.055(a)(2) for a gas well. Portions of proposed well SU 43-10 will lie within 1,500’ of property lines where ownership and / or landownership changes. Hilcorp has affirmed that Hilcorp is the sole Working Interest Owner for all tracts within 1,500’ of SU 43-10.2 On Figure 1, the surface location for the well is depicted by the red-colored dot, and the top of the Tyonek Undefined Gas Pool is indicated by the green-colored “X”, both of which lie within Cook Inlet Region, Inc. (CIRI) lease C-061723. The points at which SU 43-10 will intersect successively shallower strata lie progressively further to the west along the proposed well path. Accordingly, the only affected landowners within 1,500’ of these intersection points with shallower strata are CIRI and Mental Health Trust (adjacent MHT lease No. 9300101). If conducted as required, drilling, completion, testing, and operation of SU 43-10 as an injection well will not cause waste or result in an increased risk of fluid movement into freshwater. AOGCC Commissioner Wilson is surface owner of a property that lies within 1,500’ of the proposed well SU 43-10. Commissioner Wilson is not a mineral rights owner, has no financial interest in Hilcorp’s proposed well, and does not have a personal relationship with any of the mineral rights owners potentially affected by Hilcorp’s proposed activities. In response to Commissioner Wilson’s Ethics Supervisor Determination Form submitted for CO 826, the Office of Governor in consultation with the Department of Law determined that there is not an Ethics Act conflict that would restrict participation in this matter and confirmed that “this does not or would not violate AS 39.52.110-.190.” Copies of that form, a property location map, and the Ethics Act Determination are included in the record for CO 826. CONCLUSIONS An exception to the well spacing provisions of CO 826 is necessary to allow drilling, completion, testing, and operation of SU 43-10 as a gas development well within the following Undefined Gas Pools: Sterling, Upper Beluga, Beluga, Lower Beluga, and Tyonek. It is unlikely that a well conforming to the spacing provisions of 20 AAC 25.055 would be able to access and efficiently produce the targeted reservoir sands. If constructed and operated as required, SU 43-10 will not cause waste or result in an increased risk of fluid movement into freshwater. Correlative rights of landowners of any uncommitted tracts that lie more than 1,500’ from SU 43- 10 will be protected by adhering to the well spacing requirements of 20 AAC 25.055. 2 Suchecki, L., 2025, Hilcorp email to S.

The Office of Governor, in consultation with the Department of Law, determined that Commissioner Wilson has no Ethics Act conflicts that would restrict participation in this matter. NOW THEREFORE IT IS ORDERED The AOGCC grants Hilcorp’s October 6, 2025 application to amend CO 826 for an exception to the well spacing provisions of Regulation 20 AAC 25.055(a)(2) to allow the drilling, completion, testing, and operation of SU 43-10 as a gas development well in the Sterling, Upper Beluga, Beluga, Lower Beluga, and Tyonek Undefined Gas Pools.

Gas Pool”). Background On February 4, 2025, Hilcorp applied for an exception to 20 AAC 25.055(a)(2) to drill, complete, and produce the SU 43-10 specifying the Tyonek formation of the Sterling Field as the intended target, within 1,500’ of property line(s) where the owners or landowners are no the same on both sides of the line. On July 16, 2025, the AOGCC granted an exception to 20 AAC 25.055(a)(2) via CO 826, allowing Hilcorp to drill, complete, test and operate the SU 43-10 well in the Tyonek Und. Gas Pool of the Sterling Field. Discussion Hilcorp desires to amend CO 826 to include those potential reserves that may be encountered in the shallower depths above the Tyonek Und. Gas Pool that were previously omitted, being more particularly (in descending order): Sterling, Upper Beluga, Beluga, and Lower Beluga/Tyonek reservoir sands. Granting such an amendment would allow Hilcorp to produce said sands in the event they prove to be prospective; thereby promoting the conservation of natural gas, preventing waste, and protecting the correlative rights of the previously identified parties. The additional, shallower reserves can neither be explored for, nor efficiently developed by conforming to applicable statewide spacing regulations because of the thin, discontinuous nature of the prospective reservoir sands. 3800 Centerpoint Dr., Suite 1400 Anchorage, AK 99503 Direct: (907) 777-8432 Email: luke.suchecki@hilcorp.com By Samantha Coldiron at 11:01 am, Oct 06, 2025 Pg. 2 Application to Amend CO 826 SU 43-10 Other than the request to grant an exception to those additional, shallower sands, there are no other changes from the application for the exception to 20 AAC 25.055(a)(2) dated February 4, 2025. x The SU 43-10’s Surface Hole Location, (Estimated) Target Location, and Bottom Hole Location remain unchanged from CO 826. x All tracts within 1,500’ (red convex hull in Exhibit A-1) of the SU 43-10’s wellbore trajectory are currently leased, with Hilcorp being the sole Working Interest Owner. 20 AAC 25.055(d) In accordance with 20 AAC 25.055(d)(2), a map of the location of the SU 43-10 and its relationship to adjoining properties, along with a Tract Ownership Schedule, are attached to this application as Exhibits “A-1” and “A-2”, respectively.

According to the land plats provided with Hilcorp’s exception applications, the mineral estate owners are predominantly CIRI, the State of Alaska (SOA), and the Mental Health Trust Authority (MHT). So that the record and draft decision orders are complete, could Hilcorp please provide revised land plats on which the lease numbers are labeled for the various properties owned by CIRI, SOA, and MHT? I also note that there are other affected landowners who were also notified by certified mail. On those revised land plats, could Hilcorp also please outline and label the properties owned by each of these parties?

Herein are the materials discussed to explain the DISCLOSURE to avoid the appearance perceived conflict regarding the Hilcorp Alaska LLC request for a spacing exception on gas wells they plan to drill in the currently nonproductive Federal Sterling Unit near Soldotna, Alaska. The NOTICE topic reads: Hilcorp Alaska, LLC (Hilcorp), by letter dated February 3, 2025, filed an application with the Alaska Oil and Gas Conservation Commission (AOGCC) for an exception to the spacing requirements of 20 AAC 25.055 to allow for the drilling, completion, testing, and operation of the proposed Sterling Unit 43-10 development gas well in the Sterling Unit Sterling and Upper Beluga Pool within 1,500 feet of an external property line where the owners and landowners are not the same on both sides of the line, pursuant to 20 AAC 25.055(d). The hearing process is intended to provide notice to mineral rights owners of the intended activity and an opportunity to voice their concerns either written or orally during the hearing. The hearing has been properly noticed and there have been no requests for a hearing. As such, the AOGCC intends to vacate the hearing. The DISCLOSURE is as follows: Unless otherwise directed, I (Commissioner Wilson) intend to participate in the hearing. I am surface owner of my personal residence at 42125 Aviator Too Dr. within the boundaries of the currently nonproductive Federal Sterling Unit. My property is in close proximity to the aforementioned planned drilling activity (see map below and attached). Note that I am not a mineral rights owner and have no financial interest in the Hilcorp activity, nor will it in any way affect the use of my property or any of the comforts it affords. Nor do I have a personal relationship with any of the mineral rights owners potentially subject to the activity. As stated, none of these owners have requested a hearing or provided comments. To avoid even the appearance of impropriety, the AOGCC intends to identify the disclosure in its order. As you know, the AOGCC currently has just two commissioners, the minimum required for quorum.

However, only a few of the parcels are numbered on the maps. Who are the landowners for these properties? Were they all notified in accordance with the requirements of 20 AAC 25.055? In the past, your predecessors Cody Terrell and David Duffy provided tract maps that were labeled with tract numbers for each parcel and accompanied by an associated exhibit that detailed landownership, acreage, working interest ownership, and other information. Here is an example screenshot from the AOGCC’s CO 701A file that is available online through our Document Search application. Could Hilcorp please provide a similar map and ownership listing for SU 43-10? A similar coded map and similar ownership listing is also needed for SU 43-10RD, if any privately help parcels fall within the 3,000’ notification buffer.

However, only a few of the parcels are numbered on the maps. Who are the landowners for these properties? Were they all notified in accordance with the requirements of 20 AAC 25.055? In the past, your predecessors Cody Terrell and David Duffy provided tract maps that were labeled with tract numbers for each parcel and accompanied by an associated exhibit that detailed landownership, acreage, working interest ownership, and other information. Here is an example screenshot from the AOGCC’s CO 701A file that is available online through our Document Search application. Could Hilcorp please provide a similar map and ownership listing for SU 43-10? A similar coded map and similar ownership listing is also needed for SU 43-10RD, if any privately help parcels fall within the 3,000’ notification buffer. CAUTION: External sender.

According to the land plats provided with Hilcorp’s exception applications, the mineral estate owners are predominantly CIRI, the State of Alaska (SOA), and the Mental Health Trust Authority (MHT). So that the record and draft decision orders are complete, could Hilcorp please provide revised land plats on which the lease numbers are labeled for the various properties owned by CIRI, SOA, and MHT? I also note that there are other affected landowners who were also notified by certified mail. On those revised land plats, could Hilcorp also please outline and label the properties owned by each of these parties?

Per discussion, please see the respective, additional commentary of the requests from meeting: Attached are further updated, separate plats that address small the portion of acreage in the SE1/4 of Section 10-T5N-R10W, S.M., AK, not initially displayed as leased in prior plats by mapping error. Please note, the legend indicates unleased Tracts through hatching patterns, while leased Tracts are represented in beige. Currently, only Tract 004 is leased. Public records indicate Tract 004’s mineral ownership to be split between The Estate of Robert J. Mackey, c/o Robert Nyden (99.00%) and the Heirs or devisees of John F. McFarland (1.00%) via the attached copy of that Oil and Gas Royalty Deed, between Robert J. Mackey and John F. McFarland and Aletha A. McFarland dated May 5, 1958. Hilcorp noticed (and leased) Tract 004 Owner - Robert Nyden, as said deed reserved the right to lease for oil and gas and receive rentals to Grantor. As such, Tract 004 – Owner, Heirs or devisees of John F. McFarland was not noticed because the ownership is a non-executive mineral interest. As of today, Tract 042 – James W. Ziehler and Nancy J. Ziehler is the only Notice that has not been delivered (U.S.P.S. Tracking No. 9489017898203021081480). Communication has been established with the Owner via lease proposal by mail and telephone correspondences. Tract 042 Owner has verbally expressed the desire to lease; however, has been delayed. Tract 005 Owner, W.B. Gann & Co., communicated the desire to execute an oil and gas lease with Hilcorp on May 2, 2025. Hilcorp proposes to allocate production on an acreage basis; being the proportionate Tract Acreage within the Total Acreage that is determined to lie within the 1,500’ drainage area. Please note that the Tract Acreage calculation shall be rendered from the As-Drilled final survey plat for the SU 43-10. Should Tract 005 Owner not lease prior the SU 43-10’s completion, Hilcorp will establish and maintain, without costs to the non-participating owners and landowners, an interest-bearing escrow account for the non-participating owners and landowners and will provide documentation to the AOGCC that said escrow account has been established. Upon technical analysis from the completion of the well, Hilcorp will allocate production in accordance with the State of Alaska – Division of Oil and Gas unit and participating area decisions. I hope to have supplied you with the pertinent information to satisfy your requests. Please contact me with any questions.

Per discussion, please see the respective, additional commentary of the requests from meeting: Attached are further updated, separate plats that address small the portion of acreage in the SE1/4 of Section 10-T5N-R10W, S.M., AK, not initially displayed as leased in prior plats by mapping error. Please note, the legend indicates unleased Tracts through hatching patterns, while leased Tracts are represented in beige. Currently, only Tract 004 is leased. Public records indicate Tract 004’s mineral ownership to be split between The Estate of Robert J. Mackey, c/o Robert Nyden (99.00%) and the Heirs or devisees of John F. McFarland (1.00%) via the attached copy of that Oil and Gas Royalty Deed, between Robert J. Mackey and John F. McFarland and Aletha A. McFarland dated May 5, 1958. Hilcorp noticed (and leased) Tract 004 Owner - Robert Nyden, as said deed reserved the right to lease for oil and gas and receive rentals to Grantor. As such, Tract 004 – Owner, Heirs or devisees of John F. McFarland was not noticed because the ownership is a non-executive mineral interest. As of today, Tract 042 – James W. Ziehler and Nancy J. Ziehler is the only Notice that has not been delivered (U.S.P.S. Tracking No. 9489017898203021081480). Communication has been established with the Owner via lease proposal by mail and telephone correspondences. Tract 042 Owner has verbally expressed the desire to lease; however, has been delayed. Tract 005 Owner, W.B. Gann & Co., communicated the desire to execute an oil and gas lease with Hilcorp on May 2, 2025. Tract 005 Owner, W.B. Gann & Co., executed oil and gas lease with Hilcorp on May 12, 2025; attached, please find recorded Memorandum of Oil and Gas Lease recorded on May 28, 2025, as Instrument No. 2025-003543-0 in the Kenai Recording District. Hilcorp proposes to allocate production on an acreage basis; being the proportionate Tract Acreage within the Total Acreage that is determined to lie within the 1,500’ drainage area. Please note that the Tract Acreage calculation shall be rendered from the As-Drilled final survey plat for the SU 43-10. Should Tract 005 Owner not lease prior the SU 43-10’s completion, Hilcorp will establish and maintain, without costs to the non-participating owners and landowners, an interest-bearing escrow account for the non-participating owners and landowners and will provide documentation to the AOGCC that said escrow account has been established. Upon technical analysis from the completion of the well, Hilcorp will allocate production in accordance with the State of Alaska – Division of Oil and Gas unit and participating area decisions. I hope to have supplied you with the pertinent information to satisfy your requests. Please contact me with any questions. Luke Suchecki Hilcorp Alaska, LLC CAUTION: External sender.

According to the land plats provided with Hilcorp’s exception applications, the mineral estate owners are predominantly CIRI, the State of Alaska (SOA), and the Mental Health Trust Authority (MHT). So that the record and draft decision orders are complete, could Hilcorp please provide revised land plats on which the lease numbers are labeled for the various properties owned by CIRI, SOA, and MHT? I also note that there are other affected landowners who were also notified by certified mail. On those revised land plats, could Hilcorp also please outline and label the properties owned by each of these parties?

Per discussion, please see the respective, additional commentary of the requests from meeting: Attached are further updated, separate plats that address small the portion of acreage in the SE1/4 of Section 10-T5N-R10W, S.M., AK, not initially displayed as leased in prior plats by mapping error. Please note, the legend indicates unleased Tracts through hatching patterns, while leased Tracts are represented in beige. Currently, only Tract 004 is leased. Public records indicate Tract 004’s mineral ownership to be split between The Estate of Robert J. Mackey, c/o Robert Nyden (99.00%) and the Heirs or devisees of John F. McFarland (1.00%) via the attached copy of that Oil and Gas Royalty Deed, between Robert J. Mackey and John F. McFarland and Aletha A. McFarland dated May 5, 1958. Hilcorp noticed (and leased) Tract 004 Owner - Robert Nyden, as said deed reserved the right to lease for oil and gas and receive rentals to Grantor. As such, Tract 004 – Owner, Heirs or devisees of John F. McFarland was not noticed because the ownership is a non-executive mineral interest. As of today, Tract 042 – James W. Ziehler and Nancy J. Ziehler is the only Notice that has not been delivered (U.S.P.S. Tracking No. 9489017898203021081480). Communication has been established with the Owner via lease proposal by mail and telephone correspondences. Tract 042 Owner has verbally expressed the desire to lease; however, has been delayed. Tract 005 Owner, W.B. Gann & Co., communicated the desire to execute an oil and gas lease with Hilcorp on May 2, 2025. Tract 005 Owner, W.B. Gann & Co., executed oil and gas lease with Hilcorp on May 12, 2025; attached, please find recorded Memorandum of Oil and Gas Lease recorded on May 28, 2025, as Instrument No. 2025-003543-0 in the Kenai Recording District. Hilcorp proposes to allocate production on an acreage basis; being the proportionate Tract Acreage within the Total Acreage that is determined to lie within the 1,500’ drainage area. Please note that the Tract Acreage calculation shall be rendered from the As-Drilled final survey plat for the SU 43-10. Should Tract 005 Owner not lease prior the SU 43-10’s completion, Hilcorp will establish and maintain, without costs to the non-participating owners and landowners, an interest-bearing escrow account for the non-participating owners and landowners and will provide documentation to the AOGCC that said escrow account has been established. Upon technical analysis from the completion of the well, Hilcorp will allocate production in accordance with the State of Alaska – Division of Oil and Gas unit and participating area decisions. I hope to have supplied you with the pertinent information to satisfy your requests. Please contact me with any questions.

However, only a few of the parcels are numbered on the maps. Who are the landowners for these properties? Were they all notified in accordance with the requirements of 20 AAC 25.055? In the past, your predecessors Cody Terrell and David Duffy provided tract maps that were labeled with tract numbers for each parcel and accompanied by an associated exhibit that detailed landownership, acreage, working interest ownership, and other information. Here is an example screenshot from the AOGCC’s CO 701A file that is available online through our Document Search application. Could Hilcorp please provide a similar map and ownership listing for SU 43-10? A similar coded map and similar ownership listing is also needed for SU 43-10RD, if any privately help parcels fall within the 3,000’ notification buffer.

Sterling Unit 43-10 Sterling Unit Kenai Peninsula Borough, Alaska Hilcorp Alaska, LLC (Hilcorp), by letter dated February 3, 2025, filed an application with the Alaska Oil and Gas Conservation Commission (AOGCC) for an exception to the spacing requirements of 20 AAC 25.055 to allow for the drilling, completion, testing, and operation of the proposed Sterling Unit 43-10 development gas well in the Sterling Unit Sterling and Upper Beluga Pool within 1,500 feet of an external property line where the owners and landowners are not the same on both sides of the line, pursuant to 20 AAC 25.055(d). Surface Location: 2327' FSL, 526' FEL, Section 9, T5N, R10W, Seward Meridian (SM) Target Location (Estimated): 1706' FSL, 1187’ FWL, Section 10, T5N, R10W, SM Bottom Hole Location: 900' FSL, 1754’ FEL, Section 10, T5N, R10W, SM Well spacing regulations protect the oil and gas rights of adjacent leaseholders and landowners and maximize resource recovery by establishing default limits on how close, under the land's surface, oil and gas wells can be to property lines where ownership changes hands. These limits are set forth in a regulation, 20 AAC 25.055. Operators must abide by the default limits unless they apply for, and obtain, an order approving an exception to those limits. Although exceptions to the default limits are not unusual, AOGCC carefully evaluates each application, and typically grants them only when actual geologic conditions demonstrate that the proposed subsurface location of a well is necessary to reach otherwise unreachable oil or gas and that both the rights of adjacent leaseholders and landowners and underground drinking water can be protected. As a general matter, AOGCC does not have extensive authority over surface impacts such as noise, emissions, or construction. This notice does not contain all the information filed by Hilcorp. To obtain more information, contact the AOGCC’s Special Assistant, Samantha Coldiron, at (907) 793-1223 or samantha.coldiron@alaska.gov. The AOGCC has tentatively scheduled a public hearing on this matter for March 13 2025, at 10:00 a.m. via Microsoft Teams. The hearing, which may be changed to full virtual, if necessary, will be held in the AOGCC hearing room located at 333 West 7th Avenue, Anchorage, AK 99501. The audio call in information is (907) 202 7104 Conference ID: 160 146 389#. Anyone who wishes to participate remotely using MS Teams video conference should contact Ms. Samantha Coldiron at least two business days before the scheduled public hearing to request an invitation for the MS Teams. To request that the tentatively scheduled hearing be held, a written request must be filed with the AOGCC no later than 4:30 p.m. on February 24, 2025. If a request for a hearing is not timely filed, the AOGCC may issue an order without a hearing. To learn if the AOGCC will hold the hearing, call (907) 793-1223 after February 25, 2025. In addition, written comments regarding this application may be submitted to the AOGCC, at 333 West 7th Avenue, Anchorage, AK 99501 or samantha.coldiron@alaska.gov. Comments must be received no later than 4:30 p.m. on March 10, 2025, except that, if a hearing is held, comments must be received no later than the conclusion of the March 13, 2025, hearing. If, because of a disability, special accommodations may be needed to comment or attend the hearing, contact Samantha Coldiron, at (907) 793-1223, no later than March 6, 2025. Jessie L.

The SU 43-10 will target the Tyonek in a slightly downdip location from the SU 43-15 Tyonek producer. We believe this area to have higher net sand while still staying above the LKG from offsets. Subsurface analysis indicates additional remaining reserves to be produced. All Tertiary reservoirs in the Cook Inlet Basin are fluvial and the reservoir quality sands are thin, lenticular, and discontinuous. If the location was moved to adhere to spacing requirements, then the dry hole risk is greatly increased.
