California Resources Corporation and its carbon management business, Carbon TerraVault (CTV), announced on December 20th that the U.S. Environmental Protection Agency (EPA) released draft Class VI well permits for underground carbon dioxide (CO2) injection and storage in CTV’s 26-R reservoir located within the CTV I carbon capture and storage (CCS) vault at the Elk Hills Field in Kern County, California.
This marks an important step in advancing the development of clean energy projects in the state.
The proposed wells are California’s first draft permits for underground CO2 sequestration, as well as the first draft permits utilizing a depleted oil and natural gas field in the U.S.
“This is a significant milestone for California as it moves to attain its ambitious climate goals,” said Francisco Leon, CRC President and Chief Executive Officer. “We are committed to supporting the state in reaching carbon neutrality and developing a more sustainable future for all Californians.”
The 26-R reservoir at Elk Hills has an expected injection rate of 1.46 million metric tons (MT) per annum and a total estimated capacity of up to 38 million MT. The reservoir is part of CTV I which has a total estimated storage of up to 46 million MT. The Elk Hills Field spans nearly 75 square miles and is of particular focus for future CCS projects due to its significant storage potential through multiple depleted hydrocarbon reservoirs and its industrial location.
The California Energy Commission has referred to the Elk Hills Field as “one of the premier CO2 sequestration sites in the U.S. …an optimal site for the safe and secure sequestration of CO2.” CTV has partnered with several clean technology companies to develop greenfield projects at Elk Hills. These projects are expected to generate new jobs in new clean energy industries that will rely on the CTV I storage reservoirs.
The draft EPA Class VI permits are available for public review and comment for the next 90 days.
