CINGSA files 2024 plan of development
Plans with DNR's Division of Oil and Gas for work on gas storage lease 391627, while filings with RCA relate to utility's tariff Kristen Nelson
Cook Inlet Natural Gas Storage Alaska, CINGSA, has filed its 2024 plan of development with the Alaska Department of Natural Resources' Division of Oil and Gas for gas storage lease ADL 391627 at the Sterling C Pool. 2024 plans include the addition of two more wells and additional equipment, including two engine compressor skids.
CINGSA is on the Kenai Peninsula, with compressor station facilities on property owned by CINGSA east of the intersection of Beaver Loop Road and Bridge Access Road, while well facilities are on state property leased by CINGSA between Boat Launch Road and Bridge Access Road.
CINGSA told the division that from the beginning of production until the pool was shut-in in 2012, Sterling C produced some 23 billion cubic feet of gas from one slanted well. The pool is estimated to have initially held 26.5 bcf of gas.
Sterling C is bounded at the top by the base of the B5 coal formation and at the bottom by the top of the Upper Beluga formation.
"Hilcorp Alaska, LLC, as successor in interest to Marathon Alaska Production, LLC, retains working interest ownership of the deeper Beluga Gas and Upper Tyonek Gas Pools, both of which remain in active gas production, as well as any zones above the Sterling C," CINGSA said.
The five existing wells were drilled at the facility in 2011, with perforation and completion begun in January 2012, followed by storage injection in April 2012 and initial withdrawals in November of that year.
POD work 2023 POD work included normal maintenance and operations; installation of compressor building glycol booster pumps and associated piping; installation of well pad piping modifications to allow for future pigging; and installation of manual valves in well pad blow down stack.
CINGSA said it injected 5,050,370 thousand cubic feet of natural gas and withdrew 6,310,217 mcf in 2023.
For 2024, CINGSA said it plans normal maintenance and operations; purification shut down and maintenance in August; and modifying existing piping for tie ins of expansion project.
Expansion plans for 2024 include adding two wells, a second purification/DEHY train and expanding the compressor building to add two more engine/compressor skids.
This will provide expanded storge and throughput, CINGSA said, "while making us more reliable to meet the Greater Cook Inlet gas supply needs now and in the future."
CINGSA is a utility regulated by the Regulatory Commission of Alaska, and as previously reported in Petroleum News, in November CINGSA filed a tariff advice letter with RCA requesting approval of an additional two wells, two new gas compressors and various above-ground facilities.
