Western Australia regulator launches probe into repeated methane leaks at Chevron's Gorgon LNG project
The Western Australian Department of Water and Environmental Regulation confirmed it is investigating large methane emissions from Chevron's Gorgon LNG complex on Barrow Island. Satellite observations from the UN‑linked Tanager‑1 have recorded five plumes since November 2022, the latest showing an emission rate of about 7.8 tonnes per hour near the acid‑gas removal units. Chevron is cooperating with the state agency but has not formally responded to UN warnings. The plant can produce roughly 15.6 million tonnes of LNG each year.
Why it matters
The investigation could lead to compliance actions or fines that may affect Chevron's operating costs and reputation in a key export asset. Investors should monitor any regulatory outcomes that might impact the project's long‑term production outlook.
