Gorgon gas project
Gorgon gas project is a project for developing Greater Gorgon gas fields in the Carnarvon Basin in the North West Shelf off Western Australia, and for construction of a LNG plant on Barrow Island.
Gas fields
Greater Gorgon gas fields are located approximately 60km offshore from Barrow Island and approximately 200km west of Dampier on the Australian mainland. To the north is the North West Shelf Venture which was established in 1984.
To date, five significant fields have been discovered: Gorgon, Chrysaor, Dionysus, West Tryal Rocks and Spar.
It is a joint venture of Chevron, Shell and ExxonMobil and which is developing a number of major liquefied natural gas reserves known collectively as Greater Gorgon [1] LNG reserves in the Greater Gorgon fields are estimated to exceed 40 trillion cubic feet (1,100 km3).
Technical features
The project is currently in the planning stage and will involve:
- development of up to 30 subsea wells in water depths from 200 to 1,300 metres
- construction of subsea pipelines to Barrow Island
- three, 5 million tonne per annum LNG trains on Barrow Island
- LNG shipping facilities
- Assessment of a domestic gas plant and pipeline to the mainland
- Greenhouse gas management using carbon sequestration into geological formations beneath Barrow Island
Project company
Chevron, with a 50% interest, is the operator of the development on behalf of the Venture partners. ExxonMobil and Shell each hold 25% stakes. In 2000, Chevron inherited the assets of WAPET, an early Western Australian oil exploration operation. The Gorgon field was found in 1980, following the discovery of the West Tryal Rocks field in 1973 by WAPET.
