<h1>Greater Western Flank Phase 2 Oil and Gas Project (Western Australia,Australia)</h1>
<p>The Greater Western Flank Phase 2 (GWF-2) is an offshore conventional oil and gas project in Western Australia,Australia,operated by Woodside Energy. It forms part of the North West Shelf production system. The project develops six fields—Keast,Dockrell,Sculptor,Rankin,Lady Nora,and Pemberton—via subsea wells tied back to the Goodwyn Alpha platform. Production commenced in October 2018,ahead of schedule. Gas and condensate are processed through the Karratha Gas Plant.</p>

<h2>Project Overview</h2>
<p>GWF-2 is a gas and condensate development within the North West Shelf Project offshore Western Australia. It commercializes six fields—Keast,Dockrell,Sculptor,Rankin,Lady Nora,and Pemberton—through a subsea tie-back to the Goodwyn Alpha platform. The development comprises eight production wells arranged across four drill centres,connected by a subsea pipeline of approximately 35 to 36 kilometres. Produced gas and condensate are routed through Goodwyn Alpha to the Karratha Gas Plant for LNG and domestic gas supply.</p>
<p>The project was approved by the North West Shelf participants in December 2015 and started production in October 2018,six months ahead of schedule and US$630 million under budget. GWF-2 is an example of a brownfield subsea tie-back that uses existing offshore and onshore infrastructure to develop nearby resources.</p>
<h2>Location and Basin</h2>
<p>GWF-2 is located offshore Western Australia in the North West Shelf area,within the Northern Carnarvon Basin. The fields lie in production licences WA-5-L,WA-6-L,WA-24-L,and WA-51-R in Commonwealth waters. The development is approximately 135 to 175 kilometres north-west of Dampier,depending on the reference point. Water depths range from approximately 79 to 130 metres.</p>
<p>The proximity to Goodwyn Alpha is the key development advantage. The six fields are not developed as standalone platforms; instead,production is gathered subsea and transported to the existing host facility.</p>
<h2>Ownership and Operatorship</h2>
<p>Woodside Energy operates GWF-2 on behalf of the North West Shelf joint venture. The equity holders as of the final investment decision included Woodside Energy Ltd,BHP Billiton Petroleum (North West Shelf) Pty Ltd,BP Developments Australia Pty Ltd,Chevron Australia Pty Ltd,Japan Australia LNG (MIMI) Pty Ltd,and Shell Australia Pty Ltd,each with 16.67%. NOPSEMA materials also list China National Offshore Oil Corporation North West Shelf Private Limited among the titleholders. Revenue from GWF-2 flows through the broader North West Shelf system,supporting both LNG export and domestic gas supply.</p>

<tr><th>Milestone</th><th>Year</th><th>Details</th></tr>
<tr><td>Final investment decision</td><td>2015</td><td>The North West Shelf Project participants approved GWF-2 in December 2015. Mitsubishi Corporation and Mitsui & Co. confirmed the FID,citing eight production wells,a 35 km subsea pipeline,and recoverable reserves of 1.6 Tcf gas and 43 MMbbl condensate.</td></tr>
<tr><td>Production start</td><td>2018</td><td>Woodside reported that GWF-2 commenced production in October 2018,six months ahead of schedule. Initial production came from five wells in Lady Nora,Pemberton,Sculptor,and Rankin fields,with remaining wells in Keast and Dockrell following later.</td></tr>

<h2>Infrastructure and Facilities</h2>
<p>GWF-2 is a subsea tie-back to the Goodwyn Alpha platform. The verified infrastructure includes eight subsea production wells in four drill centres,subsea manifolds,umbilicals,subsea structures,spool pieces,and a 35 to 36 kilometre subsea pipeline. Subsea 7’s project material describes installation of a 33.4 km steel tube umbilical laid in four sections between Goodwyn Alpha and the Lady Nora drill centre,four manifolds,five subsea structures,and 18 spool pieces. Water depth in the field area is about 79 to 130 metres.</p>
<p>Goodwyn Alpha receives gas and condensate from the subsea wells and transports production to the Karratha Gas Plant onshore. No new FPSO,FLNG,LNG train,or standalone processing plant was built for GWF-2. The development relies entirely on existing North West Shelf infrastructure.</p>
<h2>Production and Reserves</h2>
<p>GWF-2 is an operating gas and condensate project. Production started in October 2018. At the time of final investment decision,recoverable reserves were reported as 1.6 trillion cubic feet of natural gas and 43 million barrels of condensate. Current project-specific production rates are not separately reported; output is integrated into the Goodwyn Alpha and North West Shelf system.</p>
<h2>Recent Developments</h2>
<p>In 2025,Woodside approved the Greater Western Flank Phase 4 (GWF-4) project,a five-well subsea tie-back to the North West Shelf with start-up targeted for 2028 and capital expenditure of approximately US$700 million. Australia also granted environmental approvals to extend the North West Shelf Project operating life to 2070,affecting the system into which GWF-2 delivers production. No new FID or major expansion has been announced specifically for GWF-2.</p>
