The Clio-3 discovery well, which is the third consecutive discovery on the Clio structure, is located in the WA-205-P permit area approximately 150km northwest of Onslow. The well is situated in 971mt of water and drilled to a depth of 4,309mt and penetrated approximately 79mt of net gas pay.

Chevron, through its Australian subsidiary, has a combined 66.66% interest, while Shell Development (Australia) holds the remaining interest. The company is conducting more tests on data gathered from the discovery well to determine the extent and commercial viability of the discovery.

George Kirkland, vice chairman of Chevron, said: “We are continuing to invest in a significant exploration program to underpin the long-term growth of our Australian business. Our continued success underscores the quality of our Australian portfolio and our technical competence.”

Jim Blackwell, president of Chevron, Asia Pacific, said: “Western Australia will play a key role in our long-term plans to build a leading natural gas business to supply energy safely and reliably to Australia and the Asia Pacific.

“We expect this discovery, together with our previous discoveries in this permit area, to underpin expansion opportunities at the Wheatstone liquefied natural gas hub.”
