GE Electric will provide power generation and undersea equipment for Chevron's Gorgon natural gas project, the utility has announced.
Under the contract, GE will supply wellheads and pipes to extract natural gas from wells drilled more than 4,000ft below the surface of the Indian Ocean, off the northwest coast of Australia.
GE will also supply gas turbines to generate power at the project's Barrow Island gas treatment and liquefaction facilities.
GE has previously been awarded a $400m contract to supply compressors to cool the gas into a liquid form and to pump CO2 removed prior to liquefaction back into the wells from which the gas is released.
Chevron and partners ExxonMobil and Royal Dutch Shell estimate it will cost about $39bn to build out the Gorgon gas wells.
The Gorgon project is one of the world's largest untapped natural gas fields, which also features one of the world's largest ever CO2 sequestration technology projects.
