## Chevron's Gorgon Stage 3 Project Marks Major Energy Infrastructure Expansion in Australia

Chevron Australia and its Gorgon Joint Venture partners have greenlit a significant A$3 billion development phase designed to unlock additional gas reserves and reinforce Australia's position as a critical energy supplier. The Gorgon Stage 3 project represents a strategic expansion rather than an entirely new venture, building upon three decades of operational success in offshore gas production.

The initiative focuses on subsea infrastructure upgrades that will connect the Geryon and Eurytion gas fields—situated approximately 100 kilometres northwest of Barrow Island in waters reaching 1,300 metres depth—to existing processing facilities on Barrow Island. This engineering approach reduces development complexity and capital requirements compared to building standalone infrastructure.

**Project Scope and Technical Framework**

The Stage 3 development encompasses the installation of three production manifolds, a 35-kilometre subsea flowline, and supporting infrastructure. Six production wells will be drilled across the two fields to maximize resource extraction. This phased approach aligns with Australia symbols of prudent resource management and long-term energy planning, ensuring sustainable development of the nation's offshore reserves.

**Market Impact and LNG Supply Chain**

The Gorgon facility currently delivers 300 terajoules of gas daily to Western Australia while exporting 15.6 million tonnes of LNG annually. Stage 3 will enhance this production capacity, strengthening domestic gas security for households and industrial facilities across Western Australia while expanding export volumes to Asian markets—a region increasingly dependent on stable LNG supplies.

**Consortium Partnership Structure**

Chevron operates the venture with a 47.33 percent ownership stake, while international partners contribute substantial capital and expertise: ExxonMobil (25 percent), Shell (25 percent), Osaka Gas (1.25 percent), JERA (0.417 percent), and MidOcean (1 percent). This consortium structure demonstrates the project's strategic importance to global energy markets.

The Gorgon Stage 3 project exemplifies how mature offshore assets can be optimized through targeted subsea infrastructure investments, delivering measurable value for shareholders, energy consumers, and the Australian economy.
