SINGAPORE, May 3 (Reuters) - Chevron Australia is working to resume full production at its Gorgon gas facility after a mechanical fault affected one liquefied natural gas (LNG) production train, a company spokesperson said on Friday.

"Repair activities have commenced and are expected to take a number of weeks," the spokesperson added.

Domestic gas and the other two LNG trains at Gorgon are unaffected and producing at full rates. (Reporting by Emily Chow Editing by David Goodman )
