Woodside Petroleum and its partners have approved $2bn expansion of North West Shelf in Australia to extract more gas.

Greater Western Flank Phase 2 (GWF-2) The project called Greater Western Flank Phase 2 (GWF-2) will be a part of North West Shelf, and designed to develop 1.6 trillion cubic feet of raw gas using subsea pipeline infrastructure to the existing Goodwyn A platform.

The project will develop hydrocarbon resources of the combined Keast, Dockrell, Sculptor, Rankin, Lady Nora and Pemberton fields located within the North West Shelf, northwest of Karratha, Western Australia (WA).

Planned to be commissioned in the second-half of 2019, the project will initially deliver gas from five wells in the Lady Nora, Pemberton, Sculptor and Rankin fields, followed by the remaining three wells in the Keast and Dockrell fields in first half of 2020.

Other project development partners include BHP Billiton Petroleum, BP Developments Australia, Chevron Australia, Shell Australia and Japan Australia LNG (MIMI) which is a joint venture between Mitsubishi and Mitsui.

All the partners equally own the Woodside Petroleum-operated project.

Woodside said that the GWF-2 Project represents the fourth major gas development in the past seven years for the NWS Project.

Woodside CEO Peter Coleman said that the GWF-2 is an economically robust project and is expected to provide significant value by leveraging Woodside’s experience in delivering major subsea tieback projects.

Coleman added: "The GWF-2 Project continues a series of NWS Project subsea tiebacks that are commercializing its gas reserves in a timely and efficient manner to extend plateau production."

In February 2015, Woodside awarded a front end engineering and design (FEED) contract to Wood Group Kenny (WGK) for the GWF-2 development project.
