AOG: The biggest project in the state's history is set for a third stage of development, five years after Chevron committed $US5 billion for Stage 2.
The biggest project in the state's history is set for a third stage of development, five years after Chevron committed $US5 billion for Stage 2.
US-based Chevron operates three LNG trains at Gorgon on Barrow Island, backed by partners including ExxonMobil and Shell.
Gorgon is the most expensive project built in Western Australia, with a price tag coming in at more than $US50 billion.
Since the facility shipped its first LNG cargo in 2016, Chevron has announced two further capital investment drives: Gorgon Stage 2 and the subsea Jansz-Io Compression project.
Both are under way, with total spending of more than $10 billion.
At an industry briefing on its forward works program during the AOG Conference in Perth, Chevron said a third stage of the project was in planning.
The company said it was running a tender process for engineering work.
That package will help Chevron assess the likely scope and cost of the development.
Further works packages are set to go to market in the year ahead, including for a drilling rig, well construction, pipeline installation and offshore services.
Gorgon is intended to have a multi-decade lifespan, which means new gas sources will be needed as existing fields deplete.
Last year, Business News reported the array of options Chevron will have for new fields.
Likely toward the top of the list were the Chrysaor and Dionysus fields in the northern Carnarvon basin, with up to six wells to be ready as early as 2027.
That would be followed by a further six wells at Geryon and Eurytion to be in production by around 2031.
An alternative would be the Clio-Acme fields, although they have previously been slated as a supply option for the North West Shelf Venture, where Chevron holds a 16.7 per cent stake.
