The Woodside Petroleum Ltd.-led Greater Western Flank project Phase 2 on the North West Shelf off Western Australia has been given the go ahead.
The GWF-2 development will tap 1.6 tcf of 2P raw gas reserves from a total of six medium-size gas fields using subsea infrastructure.
The fields—Keast, Dockrell, Sculptor, Rankin, Lady Nora, and Pemberton—will be connected by a 35-km, 16-in. pipeline to the existing Goodwyn A platform for initial processing before being fed into the main trunkline to the North West Shelf LNG and domestic gas facilities on Burrup Peninsula.
Total investment in GWF-2 is estimated to be $2 billion. The project is scheduled to be brought on stream during second-half 2019.
Initial production will come from a total of five wells in Lady Nora, Pemberton, Sculptor, and Rankin fields and followed during first-half 2020 by a total of three wells in Keast and Dockerell fields.
Woodside says GWF-2 is the fourth major gas development within the North West Shelf gas project in the last 7 years. It is described as a robust project that will deliver significant value as a tie-back to the main NWS facilities and extending the plateau production.
NWS project participants are Woodside, BHP Billiton Petroleum, BP Developments Australia, Chevron Australia, Japan Australia LNG (MIMI), and Shell Australia, all with 16.67% interest.
