Chevron has pulled the trigger on a $3 billion update to its Gorgon gas project.
The $3 billion backfill development will link the offshore Geryon and Eurytion natural gas fields in the Greater Gorgon Area to the existing subsea gas gathering infrastructure and processing facilities at Gorgon on Barrow Island. The project forms part of the Gorgon Project, operated by Chevron Australia.
Chevron Australia president Balaji Krishnamurthy said the move would maintain production at Gorgon, ensuring a long-term supply of domestic gas for Western Australian households and industry, as well as liquefied natural gas (LNG) for international customers in Asia. “Gorgon is a world-class energy asset which plays a crucial role in supporting the economic development and energy security of millions of people in Australia and across the Asia Pacific region,” he said.
“With the development of the Geryon and Eurytion fields – to join the existing Gorgon and Jansz-Io fields in providing gas supply for the processing facilities – we can continue providing the reliable energy the world needs, maintaining thousands of highly skilled jobs in Australia, supporting regional WA communities and contributing to government revenue.”
The extension, dubbed Gorgon Stage 3, is the first in a planned series of subsea tiebacks. The work involves installing three subsea manifolds and a 35-kilometre production flowline, along with associated infrastructure. Six wells will be drilled across the two new fields, located around 100 kilometres northwest of Barrow Island in waters roughly 1,300 metres deep.
Krishnamurthy described Gorgon Stage 3 as a cost-competitive development that will optimise existing infrastructure and complement the already well-advanced Jansz-Io Compression Project and the previously completed Gorgon Stage 2 infill development.
