ExxonMobil's affiliate Mobil Exploration Producing Australia Pty Ltd (MEPA) has a 35 per cent interest in the Griffin oil field. Griffin is located in the offshore Carnarvon Basin on the North West Shelf of Australia, almost 70 kilometres north-west of Onslow. The Griffin field was discovered in 1989 and commenced production in January 1994.

Griffin is operated by BHP Billiton and consists of a floating production, storage and offloading facility (FPSO). Oil and gas from the Griffin field is produced through the purpose built vessel named the "Griffin Venture". The vessel processes the fluids, stores the oil, and exports the associated gas through a 68 kilometre pipeline to shore. Oil is also delivered to shuttle tankers via a floating hose.

The produced gas is sold into the Western Australia domestic market.
