Chevron Corp. has received a greenhouse gas (GHG) assessment permit for a nearly 8,500-sq-ft block being evaluated to become part of an emissions storage hub offshore Western Australia, the company said on Aug. 22.

With the permit, the company gains an opportunity to build on its carbon capture and storage (CCS) portfolio working with partner Woodside Energy Ltd.

“Together with the Chevron-operated Gorgon CCS project, one of the world’s largest integrated facilities, coupled with our existing GHG assessment permits, this new award has potential to expand Chevron’s portfolio of CCS assets in Australia,” said Chris Powers, vice president of CCUS & Emerging for Chevron New Energies.

Chevron will be the operator of the joint venture for the permit and will hold a 70% participating interest, while Woodside will hold a 30% participating interest, according to a news release. Chevron said it has agreed to farm down 5% of its equity in the permit to GS Caltex of Korea, if regulatory approvals and others conditions are met.

The G-18-AP Block, where water depths range from 50 m to 1,100 m, adds to Chevron’s non-operated interests in three other blocks off Australia. Chevron said its Gorgon CCS has captured and stored more than 10 million tonnes of CO2 equivalent. The system, which injects carbon emissions into a large sandstone formation 2 km beneath Barrow Island for permanent storage, is part of Chevron Australia’s Gorgon LNG facility.
