Project Profile
Value: US$2.0 billion
Location: north-west coast of Australia, Western Australia
Reserves: 3 trillion cubic feet of gas and 100 million barrels of condensate (phase 2 - 1.6 Tcf of natural gas and 43 million barrels of condensate)
Start-up Year: second half of 2019 (phase 2)
The Greater Western Flank is part of Woodside\'s plan to extend the life of Australia\'s biggest operating LNG facility as current reserves start depleting toward the end of this decade. The project, estimated to contain 3 trillion cubic feet of gas and 100 million barrels of condensate, will help maintain the Shelf\'s current capacity of around 16.5 million metric tons of LNG a year. Woodside has no plans to expand production by adding more processing trains to the Shelf\'s existing five units, the last of which was commissioned in 2008. Instead, the partners are incrementally expanding output by making better use of the existing infrastructure. The Shelf produced 16.5 million tons of LNG in calendar 2010, above its nominal rated capacity of 16.3 million tons. Woodside is operator of the North West Shelf, partnered by BHP Billiton Ltd., Chevron Corp., BP, Royal Dutch Shell and Japan Australia LNG.
In December 2015, the North West Shelf Project (NWS Project) made a final investment decision on the Greater Western Flank Phase 2 (GWF-2) gas fields development project off the north-west coast of Australia. The GWF-2 Project will involve the drilling of eight natural gas production wells in the six gas fields within the development area. The plan calls for connecting these wells to the existing Goodwyn A platform via a 35-kilometer subsea pipeline. The natural gas produced by the project will be transported to the Karratha Gas Plant, where it will be converted into liquefied natural gas (LNG) for shipment and sale to customers or will be provided as domestic gas. Total investment for the project is expected to be approximately US$2.0 billion (Operator\'s estimate; 100% cost), with MIMI\'s equity share amounting to approximately US$330 million. Recoverable reserves are estimated at 1.6 trillion cubic feet (Tcf) of natural gas and 43 million barrels of condensate. Production is scheduled to begin in the second half of 2019.

Wood Group Kenny (WGK): Contract with Woodside to provide the front end engineering design (FEED) of the flowline system, and associated procurement support, for the proposed Greater Western Flank Phase 2 (GWF-2) development for the North West Shelf (NWS) Project, offshore Western Australia. The scope of work includes engineering and procurement support services for the 16\" GWF-2 corrosion resistant alloy rigid flowline system, flowline end termination structures, inline tee assembly structures, mid connection structure and subsea tie-in spools. The primary engineering focus of the GWF-2 flowline FEED is to develop the flowline system for the final investment decision planned for the second half of 2015.
Subsea7: Contracted for subsea tie-back of adjacent fields to the GWA platform, including the installation of manifolds, umbilicals and spool pieces, together with the pre- commissioning of the system. Project management and engineering will commence immediately from Subsea 7\'s office in Perth, Australia, with offshore operations scheduled to commence in 2018. (December 2016)
