Chevron has revealed plans to invest AUD 3 billion ($2 billion) in a backfill project that will connect the offshore Geryon and Eurytion gas fields to Gorgon’s existing subsea infrastructure and processing facilities on Barrow Island.
This development, known as the Gorgon Stage 3 project, is part of the original Gorgon plan and marks the first phase of a series of subsea tiebacks. It will complement the Jansz-Io compression project and the earlier Gorgon Stage 2 infill development.
The project includes the installation of three manifolds and a 35 km production flowline, along with other necessary infrastructure. Additionally, six wells will be drilled in the Geryon and Eurytion fields, located approximately 100 km northwest of Barrow Island in around 1,300 meters of water.
Chevron Australia president Balaji Krishnamurthy said this development would help sustain production at Gorgon, ensuring a reliable supply of domestic gas for Western Australian households and industries, as well as liquefied natural gas (LNG) for international markets in Asia.
“By adding the Geryon and Eurytion fields to the existing Gorgon and Jansz-Io fields, we can ensure a steady energy supply, support thousands of skilled jobs in Australia, contribute to regional WA communities, and generate revenue for the government,” Krishnamurthy said.
Gorgon has the capacity to produce 300 terajoules per day of gas and 15.6 million tonnes of LNG annually.
