<h1>Browse to North West Shelf Oil and Gas Project,Western Australia,Australia</h1>
<p>The Browse to North West Shelf Oil and Gas Project is a proposed offshore development in Western Australia. It is intended to develop the Brecknock,Calliance,and Torosa gas and condensate fields in the Browse Basin and deliver gas to the existing North West Shelf Project infrastructure. Woodside Energy is operator for the Browse Joint Venture. Woodside describes Browse as Australia’s largest undeveloped offshore gas resource,with a project capacity of 11.4 million tonnes per annum for LNG,LPG,and domestic gas. The proposed development concept includes two FPSO facilities and a long offshore gas pipeline to the North West Shelf system’s Karratha Gas Plant. The project is pre-production and has not reached a final investment decision.</p>

<h2>Location and Operating Area</h2>
<p>The project is located offshore Western Australia in the Browse Basin,approximately 425 km north of Broome. The project coordinates are approximately 13.99°S,121.98°E. The blocks are WA-30-R,WA-31-R,and WA-32-R. The remote offshore location requires floating production facilities,subsea infrastructure,and a long gas pipeline to existing North West Shelf facilities.</p>
<h2>Operator and Ownership</h2>
<p>Woodside Energy operates the project on behalf of the Browse Joint Venture. Participating interests are Woodside Browse Pty Ltd (30.60%),BP Developments Australia Pty Ltd (44.33%),Japan Australia LNG (MIMI Browse) Pty Ltd (14.40%),and PetroChina International Investment (Australia) Pty Ltd (10.67%). Parent companies include BP PLC,Woodside,PetroChina,and the Mitsubishi and Mitsui groups. In May 2026,Reuters reported that Inpex had agreed to acquire PetroChina’s 10.67% stake,subject to regulatory approval and partner consent. Woodside was assessing pre-emption rights.</p>
<h2>Development History</h2>
<p>The Browse fields have a long development history. Earlier concepts included an onshore LNG plant at James Price Point and floating LNG. The current Browse to North West Shelf concept routes gas to the Karratha Gas Plant. The project is classified as discovered and advanced,but a final investment decision has not been publicly confirmed. In September 2025,the Australian federal government approved the North West Shelf Project Extension,which allows the Karratha Gas Plant to operate until 2070,subject to conditions. Legal challenges have been filed against that approval.</p>
<h2>Infrastructure</h2>
<p>The proposed development includes two FPSO facilities with capacities of 1,100 million standard cubic feet per day,an 85-kilometer inter-field spur line,and a main pipeline to existing infrastructure near the North Rankin Complex. Gas would be processed at the Karratha Gas Plant. Condensate will also be produced. Detailed design is not finalized as the project is pre-FID.</p>
<h2>Production and Reserves</h2>
<p>The project is not in production. Woodside describes the resource as Australia’s largest undeveloped offshore gas resource. Public summary materials estimate the Brecknock,Calliance,and Torosa fields contain approximately 13.9 trillion cubic feet of dry gas and 390 million barrels of condensate. These are resource estimates,not production data.</p>
<h2>Recent Developments</h2>
<p>In September 2025,the North West Shelf Project Extension received federal approval with 48 additional conditions. Legal challenges were filed in October 2025 on environmental and cultural grounds. In May 2026,Reuters reported Inpex’s agreement to acquire PetroChina’s stake and Woodside’s assessment of pre-emption rights. The project remains pre-production.</p>
