The US supermajor said it has made the discovery at the Pontus-1 well on the WA-37-L block in the Greater Gorgon Area of the Carnarvon basin.

Chevron has struck 30 metres of net gas pay at the well which was drilled to 5054 metres in 210 metres of water.

The oil giant said the discovery will help contribute to development of the larger Gorgon gas project on the field.

The latest well is situated about 65 kilometres north-west of Barrow Island off Western Australia.

Chevron is operator of the block with a 47.3% share while ExxonMobil and Shell each sit on 25%. Japanese outfits Osaka Gas, Tokyo Gas and Chubu Electric Power hold 1.25%, 1% and 0.42% respectively.
