Woodside developing North West Shelf gas

By OGJ editors

Woodside Energy Ltd. is expanding development of North West Shelf Project natural gas fields off Western Australia and has begun letting contracts.

The Greater Western Flank (GWF) Phase 1 Project will develop Goodwyn GH and Tidepole gas fields with a subsea tieback to the Goodwyn A platform, which stands in 131 m of water (see map, OGJ, Oct. 17, 2005, p. 35).

The fields lie in 70-130 m of water about 130 km northwest of Karratha. They are among 16 fields southwest of Goodwyn A estimated to hold a total of as much as 3 tcf of recoverable natural gas and 100 million bbl of recoverable condensate.

Woodside expects production from Goodwyn GH and Tidepole to begin early in 2016. It didn’t disclose rates.

The North West Shelf Project encompasses a gas plant and five-train LNG liquefaction and export complex at Karratha and delivers dry gas for domestic use.

For the GWF Phase 1 Project, FMC Technologies Inc. has a contract to design, manufacture, and supply six subsea production trees, six wellheads, two manifolds, subsea and topside controls, and flowline connection systems.

Technip will load out, transport, and install 16 km of 16-in. gas flow line between the Tidepole manifold and Goodwin A platform.

GWF Phase 1 participants are Woodside Energy (operator), BHP Billiton Petroleum (North West Shelf) Pty., BP Developments Australia Pty. Ltd., Chevron Australia Pty. Ltd., Japan Australia LNG (MIMI) Pty. Ltd., and Shell Development (Australia) Pty. Ltd., with 16.67% interests each.
