The North West Shelf (NWS) operator Woodside Petroleum and its partners have approved the $1.2billion Persephone project.
It is the third major gas development for the NWS project, which is off the north-west coast of Australia.
The project will involve a two well, 7km subsea tieback from the Persephone field to the existing North Rankin complex.
Woodside said the project start-up was expected in early 2018.
Peter Coleman, chief executive of Woodside, said the project would leverage Woodside’s core capabilities to unlock undeveloped resources and help maintain offshore supply to the Karratha gas plant.
He said: “The NWS Project celebrated 30 years of domestic gas production and 25 years of LNG exports earlier this year and the approval of Persephone is the next step in continuing this success story.”
The Persephone project participants are its operator Woodside Energy, BHP Billiton Petroleum, BP Developments Australia, Chevron Australia, Japan Australia and Shell Development.
