I. Supervisor FROM: Guy Cook SUBJECT: Unmanned Flowback Petroleum Inspector Milne Point Unit H-21 Hilcorp Alaska LLC PTD 2250600; Sundry 325-611 10/15/2025: I arrived on site and met with Derick Weglin with Hilcorp. We visually inspected the temporary hardline set-up for flowing the well unmanned. The well’s normal safety valve system was in place and functional. Temporary 2-inch and 3-inch hardline takes the place of a welded/flanged production lateral line and power fluid line. All looked good with no issues noted. This well will be an injector when the temporary flowback set up is done being used.

Per Statute AS 31.05.030(d)(2)(B) and Regulation 20 AAC 25.071, composite curves for all well logs run must be submitted to the AOGCC within 90 days after completion, suspension, or abandonment of this well, or within 90 days of acquisition of the data, whichever occurs first. The permit is approved subject to full compliance with 20 AAC 25.055. Approval to produce or inject is contingent upon issuance of a conservation order approving a spacing exception. The Operator assumes the liability of any protest to the spacing exception that may occur. See CO 477B.001. This permit to drill does not exempt you from obtaining additional permits or an approval required by law from other governmental agencies and does not authorize conducting drilling operations until all other required permits and approvals have been issued. In addition, the AOGCC reserves the right to withdraw the permit in the event it was erroneously issued. Operations must be conducted in accordance with AS 31.05 and Title 20, Chapter 25 of the Alaska Administrative Code unless the AOGCC specifically authorizes a variance. Failure to comply with an applicable provision of AS 31.05, Title 20, Chapter 25 of the Alaska Administrative Code, or an AOGCC order, or the terms and conditions of this permit may result in the revocation or suspension of the permit. Sincerely, (SFHPSZ $. 8JMTPO Commissioner DATED this 31st day of July 2025. Gregory C. Wilson Digitally signed by Gregory C. Wilson Date: 2025.07.31 15:48:07 -08'00' JLC 7/31/2025 Gregory C.
