2024 Kenai Gas Field
Hilcorp Alaska, LLC February 12, 2025 Mr. Brett Huber, Commissioner Alaska Oil and Gas Conservation Commission 333 W. 7th Avenue, Suite 100 Anchorage, AK 99501 Re: Kenai Gas Field SIO #7 2024 Sterling Pool 6 Annual Performance Evaluation Dear Commissioner Huber: Attached for your review is the 2024 Annual Performance Evaluation for the Sterling Pool 6 Gas Storage Reservoir according to SIO #7. This report covers the primary production and injection period through the 2024 gas storage operations. Injection wells continue to act as expected based on an injectivity index. Real time downhole pressure monitoring is possible with shut in tubing pressures (SITP) of KU 34-31 corrected to reservoir pressure. Exhibit #4 graphically shows the P/Z data during the 2024 calendar year. In that exhibit, it appears the Pool 6 pressure [as measured from KU 34-31] increased at a higher rate than in previous injection periods. This may be due to a hysteresis effect caused by the lower injection rates or lower mean yearly pressure in 2020 thru 2024. For the annual period ending 12/31/2024 the total volume injected into Sterling Pool 6 was 3.99 BSCF and total production was 5.69 BSCF. The native gas was determined to be fully depleted as of November 2017. All Pool 6 gas production throughout 2024 was considered 100% storage gas. The maximum reservoir pressure recorded in Pool 6 based on the KU 34-31 monitoring well SITP was 201 psig or a reservoir pressure of 235 psia. This pressure is expected to be distributed consistently throughout the productive area of Pool 6 and is below the maximum reservoir pressure of 400 psi as established by rule #6 of SIO 7A.
