US supermajor Chevron has revealed plans to invest AUD 3bn ($2bn) in a backfill development that will connect the offshore Geryon and Eurytion natural gas fields to Gorgon’s existing subsea gas-gathering infrastructure and processing facilities on Barrow Island.
This so-called Gorgon Stage 3 project, part of the original development plan for Gorgon, is the first in a series of planned subsea tiebacks. This phase will complement the Jansz-Io compression project and previously completed Gorgon Stage 2 infill development.
The development involves installing three manifolds and a 35 km production flowline, along with associated infrastructure.
Six wells will be drilled in the two fields located about 100 km northwest of Barrow Island in water depths of about 1,300 m.
Chevron Australia president Balaji Krishnamurthy said the development would maintain production at Gorgon, enabling the long-term supply of domestic gas for WA households and industry, and liquefied natural gas (LNG) for international customers in Asia.
“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,” he said.
Gorgon has the capacity to produce 300 terajoules per day of gas and 15.6m tonnes of LNG per year.
