Gorgon CCS

The Gorgon CCS Project, operated by Chevron Australia with joint venture partners ExxonMobil, Shell, Osaka Gas, Tokyo Gas, and JERA, is located on Barrow Island, Western Australia. Commissioned in 2019, it is one of the world’s largest integrated CCS projects and was designed to capture and inject up to 3.3–4 million tonnes of CO₂ per year from the associated gas fields into the Dupuy Formation, a deep sandstone reservoir sealed by thick marine shales. The project was developed to reduce emissions from the Gorgon LNG facility, with a target of capturing about 80% of reservoir CO₂. Since startup, the project has not yet reached its targeted capture levels, with annual performance ranging from 30–44% of CO₂ removed from the gas stream, equating to about 1.6 million tonnes per year. The variance has been attributed to technical challenges in managing reservoir pressure, leading to ongoing optimization and infrastructure upgrades, including new water extraction and injection wells. The project continues to operate while implementing these adjustments, with the aim of increasing capture rates and improving long-term performance.
