Chevron Discovers More Gas Off West Australian Coast

Published at 10:11AM - 02/05/15

Chevron Australia has made another significant natural gas discovery in the Greater Gorgon area of the Carnarvon Basin, offshore north-west Australia.

Chevron’s Isosceles-1 exploration discovery well has discovered approximately 134 metres (440 feet) of net gas pay at a water depth of 968 metres (3,175 feet) in the Triassic Mungaroo Sands.

President of the Chevron Asia Pacific Exploration and Production Company, Melody Meyer, said ‘This discovery is a continuation of our exploration success and further positions our company as a key supplier for future liquefied natural gas (LNG) demand in the Asia-Pacific region.’

The find is located in the WA-392-P permit area, which Chevron Australia operates and in which it holds a 50% stake; Shell Australia and Mobil Australia Resources each holds 25% in the permit.

WA-392-P is around 95 miles from Barrow Island, where Chevron is currently constructing a 15.6 million tonne per annum liquefied natural gas (LNG) plant – part of its massive Gorgon Project.


Chevron describes the Gorgon Project as one of the world’s biggest natural gas projects and the largest single-resource development in Australia’s history. The project will develop the Gorgon and Jansz-Io gas fields, both located within the Greater Gorgon area, which is between 130 and 220 kilometres off Western Australia’s northwest coast and has proven hydrocarbon reserves of 13.8 Tcf.

As well as the LNG plant, Gorgon will feature a 2.1 kilometre-long loading jetty for transporting LNG to international markets, and a natural gas plant from which gas will be piped to the mainland for the domestic market.
