To commercialise the gas reserves of the Wheatstone and Iago gas fields, in the Western Carnarvon Basin off the north-west coast of Western Australia, an LNG plant will be built at Ashburton North, 12 km south-west of Onslow.
Natural gas resources at Wheatstone are anticipated to be large enough to fill two LNG processing trains, each with a capacity of 4.3 million tonnes of LNG per annum and a domestic gas plant. This will provide Australia with increased energy security and help to meet growing demand for cleaner energy, with greenhouse emissions from LNG significantly lower than those produced by conventional coal-fired electricity.
“Drawing on all the human energy in Chevron, including at the Global Technology Centre in Perth, will help make Wheatstone the most advanced, environmentally responsible LNG project in the world,” said Senior Environmental Engineer for Golder Associates, Peter Reeves.
Golder will provide geotechnical consultation for the design and construction of the LNG plant and associated infrastructure.
A four month field program of geotechnical investigations will utilise four onshore drill rigs, two nearshore jack up barges, in-situ down-the-hole pressuremeter testing, down-the-hole seismic testing, cone penetration tests and test pitting.
Chevron discovered Wheatstone in August 2004 and announced their intention to develop the gas resource at a greenfield onshore LNG and domestic gas project in March 2008.
