Giant energy firm Chevron Corporation revealed on Friday that it has discovered fresh gas deposits on its Carnarvon Basin offshore project in Western Australia where the company is developing two huge liquefied natural gas LNG facilities.

The US company reported that it has stumbled surprise gas reservoir near its Brederode-1 well, which is still within its 50 percent owned WA-364-P permit area, and initial tests yielded and estimated 15 metres or 49 feet of net gas pay.

Chevron said that the discovery site is nearby its previous Kentish Knock gas finds and just west of BHP Billiton Ltd's Thebe discovery as it noted that the permit is 50-percent co-owned by Shell.

Chevron Asia Pacific Exploration and Production Co president Jim Blackwell is excited that the new discovery would further extend the company's offshore gas resources and consequently increase its Australian gas portfolio.

Mr Blackwell said that the Brederode-1 find "expands the resource potential in the Carnarvon Basin frontier and demonstrates our long-term commitment to developing Australia's world-class natural gas resources."

However, Chevron opted not to clarify if the company's new discovery would be tapped into existing projects and pump more supplies to its Gorgon and Wheatstone LNG facilities.
