The US$2 billion backfill development will connect the offshore Geryon and Eurytion natural gas fields in the Greater Gorgon Area to Gorgon’s existing subsea gas gathering infrastructure and processing facilities on Barrow Island.
The development will 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.
Part of the original development plan for Gorgon, Gorgon Stage 3 is the first in a series of planned subsea tiebacks.
The development involves the installation of three manifolds and a 23-mile (35-km) production flowline among other associated infrastructure.
Six wells will be drilled in the two fields located about 62 miles (100 km) northwest of Barrow Island in water depths of about 4265 ft. (1300 m).
The Chevron-operated Gorgon Project is a joint venture between the Australian subsidiaries of Chevron (47.33%), ExxonMobil (25%), Shell (25%), Osaka Gas (1.25%), MidOcean (1%), and JERA (0.417%).
Gorgon is one of the world’s largest LNG projects and the largest single resource project in Australia’s history. Located on Barrow Island, Gorgon comprises a three-train, 15.6 MTPA LNG facility and a domestic gas plant with the capacity to supply 300 terajoules of gas per day to Western Australia.
The Gorgon Project is located on Barrow Island, 37 miles (60 km) off the northwest coast of Western Australia.
