Woodside Energy Ltd. is operator of the $27 billion North West Shelf Venture NWSV).
The broader Greater Western Flank (GWF) area consists of 16 fields located to the south west of the Goodwyn A (GWA) platform, estimated to hold up to 3 Tcf of recoverable gas and up to 100 MMbbl of recoverable condensate.
The GWF Phase 1 Project will develop the Goodwyn GH and Tidepole fields, via a subsea tie-back to the existing GWA platform and represents the next major development for the North West Shelf Project.
The six GWF Phase 1 Project participants are: Woodside Energy Ltd. (Operator 16.67%); BHP Billiton Petroleum (North West Shelf) Pty Ltd (16.67%); BP Developments Australia Pty Ltd (16.67%); Chevron Australia Pty Ltd (16.67%); Japan Australia LNG (MIMI) Pty Ltd (16.67%); and Shell Development (Australia) Proprietary Limited (16.67%).
The total investment for the GWF Phase 1 Project is about A$2.5 billion (Operator’s estimate; 100% cost) with project start-up expected early 2016.
Five wells will be drilled in the Goodwyn H and Tidepole fields. Subsea facilities will be installed at each wellhead to regulate well stream flows.
Rigid spools will link the flowbases and pipeline tie-in points and manifolds. The pipeline will be 16-inch and approximately 16 km in length. An electro-hydraulic open loop control system will provide control of production, tree valves and chokes and monitoring of well parameters.
A retrofitted riser will bring fluids on board GWA, where the gas/condensate production will initially treated in the high pressure train (T100) prior to entering the compression train (T200).
The processed gas will be exported via existing facilities to the onshore gas plant.
