Chevron Australia and the Gorgon joint venture participants have taken a final investment decision (FID) to proceed with Gorgon Stage 3 development off the northwest coast of Western Australia (WA).
The $3-billion (Aus.) backfill development will connect offshore Geryon and Eurytion natural gas fields in the Greater Gorgon Area to Gorgon’s existing subsea gas gathering infrastructure and processing infrastructure on Barrow Island, the company said in a release Dec. 5.
Chevron Australia president Balaji Krishnamurthy said the development would maintain production at Gorgon, enabling the long-term supply of domestic gas for WA, 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.”
Gorgon Stage 3 is part of the original development plan for Gorgon and is the first in a series of planned subsea tiebacks.
Development involves installation of three manifolds and a 35-km production flowline among other associated infrastructure.
Six wells will be drilled in the two fields, which lie about 100 km northwest of Barrow Island in water depths of about 1,300 m.
“Gorgon Stage 3 is a cost-competitive development which will optimize existing infrastructure and complement the well-progressed Jansz-Io Compression Project and previously completed Gorgon Stage 2 infill development,” Krishnamurthy said.
