Division approves CINGSA 2025 POD
Kristen Nelson Petroleum News
The Alaska Department of Natural Resources' Division of Oil and Gas has approved the Cook Inlet Natural Gas Storage Alaska LLC 2025 plan of development for gas storage lease ADL 391627, submitted Jan. 31.
In its April 2 approval the division said the 2025 POD is approved for April 3 through April 2, 2026.
The division said CINGSA converted the Sterling C1-C2 sandstone in the Cannery Loop unit into a natural gas storage reservoir in 2012. The reservoir covers some 1,272 acres within the Hilcorp Alaska-operated Cannery Loop unit, with CINGSA surface operations on two gravel pads. CINGSA owns the surface land where the Plant Pad is located and the state owns the surface land where the Well Pad is located.
CINGSA drilled five injection/withdrawal service wells and in early April 2012 began injection of free flow gas, followed by injection with compression at the end of that month, and initial withdrawals in early November 2012.
In 2014, CINGSA drilled two additional injection/withdrawal service wells.
During the 2024 POD, CINGSA injected some 5,585,904 thousand cubic feet of natural gas and withdrew some 5,453,126 mcf.
In December 2024 the Alaska Oil and Gas Conservation Commission allowed CINGSA's maximum storage volume to increase from 18 billion cubic feet to 20 bcf, with 7 bcf of the maximum being base gas.
New storage wells In 2024 CINGSA drilled the CLU S-6 and CLU S-7 using Nordic Calista RG37-04. The division said perforation and completion were delayed awaiting availability of a coil tubing unit, but during the March 12, 2025, technical meeting on the 2025 POD, CINGSA said the wells had been perforated and completed.
Other work completed under the 2024 POD included:
*April and September semiannual shut-ins for maintenance;
*Two new compressor skids installed, including expansion of compressor building;
*Surface piping installed for new wells;
*Installation of additional DEHY purification train begun; and
*Plant pad expansion near compressor building and warehouse to accommodate new equipment and building expansions.
Under the 2025 POD, in addition to continuing storage operations and doing semi-annual maintenance in April and September, CINGSA will commission a gas purification system and expand the existing warehouse.
Storage operations will continue in CLU S-7, put into service in February, and flow testing will continue for CLU S-6, "with the intention to put this well into service by the end of calendar year 2025," the division said.
