2023 Swanson Tyonek
Hilcorp Alaska, LLC February 22, 2024 Mr. Brett Huber, Commissioner Alaska Oil and Gas Conservation Commission 333 W. 7th Avenue, Suite 100 Anchorage, AK 99501 Re: 2023 Annual Material Balance Calculations of Production and Injection Volumes – Swanson River Gas Storage Facility #3 (Tyonek 77-3 sand) Swanson River Field Dear Commissioner Huber: Attached for your review is the annual material balance calculation of production and injection volumes for the Swanson River Gas Storage Facility #3 (SRGSF #3), as required per AOGCC Storage Injection Order #6 (SIO #6). This material balance report covers the primary production period (Jul. 2004 – Nov. 2005), as well as the gas storage operations that have taken place since Dec. 2005. The 77-3 reservoir in the Swanson River field was in active use for all of 2023 and was an important component of total gas deliverability for the Cook Inlet. Three active wells were used for injection and production in 2023: SCU 42-05X, SCU 42-05Y, and SCU 42-05Z. Hilcorp has performed material balance calculations on the 77-3 reservoir to provide assurance of continued reservoir confinement of the gas storage volumes. Supporting data is attached in numerical and graphical form (P/Z plot) for the convenience of the reader. BHP calculations were made for the 2023 storage cycle between January and December. These data points are plotted with the historical data and they conform to the overall curve, indicating continued confinement of the storage gas.
