chevron Greenlights $3 Billion Gorgon Stage 3 Expansion, Securing Australian Gas Supply to 2070
PERTH, AUSTRALIA – December 5, 2025 – Chevron and its partners have approved a significant $3 billion investment in the Gorgon Stage 3 growth project, located off the north-west coast of Western Australia. The expansion aims to bolster the existing LNG export facility and ensure a long-term domestic gas supply for the region, potentially extending the field’s lifespan to 2070.
The Gorgon Joint Venture, comprised of Chevron’s Australian units, ExxonMobil (XOM), Shell (SHEL), Osaka Gas (9532), JERA, and MidOcean, collectively owning 97.3% of the project, reached the final investment decision on Friday.
Stage 3 will focus on connecting the Geryon and Eurytion offshore natural gas fields to the existing Gorgon infrastructure on Barrow island. The project involves drilling six wells across the two fields as part of a broader series of planned subsea tie-ins.
The project received environmental approval from the Offshore Environmental Regulatory Authority in November, following a public comment period initiated by Chevron in August 2024.
“Along with LNG exports, the project will enable the long-term supply of domestic gas to Western Australian households and industry,” stated Balaji Krishnamurthy, Chevron Australia president. This commitment aligns with the state’s 15% domestic reserve policy for all LNG projects.
Currently, the Gorgon Project boasts a capacity to produce 300 terajoules per day of gas for the Western Australian market and 15.6 million tonnes of LNG annually. chevron’s filings with the regulator indicate plans for a maximum of 40 wells across seven fields, suggesting a robust and enduring energy source for decades to come.
This approval follows closely on the heels of the regulator’s acceptance of Shell’s plans to develop the Crux field, also located off northern Australia, signaling continued investment in the region’s significant natural gas reserves. the Gorgon Stage 3 expansion underscores australia’s critical role in global energy markets and its commitment to meeting both international and domestic energy demands.

Chevron’s $2 Billion Gorgon LNG Investment: Fueling Australia’s Energy Future
Chevron Australia has received approval for a notable $2 billion investment into the Gorgon LNG project, located off the coast of Western Australia. This substantial financial commitment signals continued confidence in the long-term viability of the project and its role in the global Liquefied Natural Gas (LNG) market. The investment is poised to enhance operational efficiency, expand export capabilities, and solidify Gorgon’s position as a major energy supplier.
Understanding the Gorgon LNG Project
The Gorgon LNG project is one of the world’s largest natural gas projects. Operated by Chevron, it involves the growth of gas fields located in the Carnarvon Basin. Key aspects of the project include:
* Gas Fields: Gorgon and Jansz-Io gas fields are the primary sources of natural gas.
* Processing Facilities: Located on Barrow island, Western australia, these facilities liquefy the natural gas for export.
* Export Capacity: The project boasts a three-train LNG plant with a combined capacity of 15.6 million tonnes per annum (mtpa).
* Ownership: Chevron holds a 47.3% stake, ExxonMobil 25%, Shell 25%, Osaka Gas 7.5%, and Tokyo gas 10%.
Breakdown of the $2 billion Investment
The $2 billion investment isn’t a single allocation; it’s strategically distributed across several key areas to maximize impact. While specific details are often proprietary, industry analysis suggests the following allocation:
* Infrastructure Upgrades (approx.$800 million): Modernizing existing infrastructure, including pipelines, processing units, and loading facilities, to improve reliability and reduce downtime. This includes potential upgrades to the LNG plant itself.
* Technological Advancements (approx. $600 million): Implementing cutting-edge technologies to enhance gas recovery rates, optimize energy consumption, and minimize environmental impact. this could involve digital twins, advanced analytics, and automation.
* Drilling and Well Development (approx. $400 million): Funding further exploration and development of gas reserves within the Gorgon and Jansz-Io fields, extending the project’s lifespan.
* Sustainability Initiatives (approx. $200 million): Investing in projects aimed at reducing carbon emissions, improving water management, and protecting the surrounding marine habitat.
Impact on LNG Exports and Global Markets
This investment directly impacts Australia’s position as a leading LNG exporter.
* Increased Export Capacity: While not necessarily expanding the total capacity of the three trains instantly, the upgrades will improve operational efficiency, leading to higher sustained production and more reliable exports.
* meeting asian Demand: The majority of Gorgon’s LNG is exported to key Asian markets, including Japan, China, south Korea, and Singapore. This investment ensures a stable supply to meet growing energy demands in the region.
* Energy Security: LNG plays a crucial role in diversifying energy sources and enhancing energy security for importing nations. Gorgon’s contribution is significant.
* LNG Pricing: Increased supply, even incrementally, can influence global LNG spot prices, potentially offering benefits to consumers.
Technological Innovations Driving Efficiency
Several technologies are likely to be central to the investment:
- Digital Twins: Creating virtual replicas of physical assets allows for predictive maintenance,optimized performance,and reduced operational costs.
- Advanced Analytics & AI: Utilizing data analytics and artificial intelligence to identify patterns, optimize processes, and improve decision-making.
- Enhanced Gas Recovery Techniques: Implementing advanced drilling and completion techniques to maximize gas extraction from existing reservoirs.
- Carbon Capture, Utilization, and Storage (CCUS): While large-scale CCUS at Gorgon has faced challenges, further investment in this area could be part of the sustainability initiatives.
- Automated Inspection & Robotics: Deploying robots and drones for inspection and maintenance tasks, reducing human risk and improving efficiency.
Environmental Considerations and Sustainability
The Gorgon LNG project has faced scrutiny regarding its environmental impact. This investment includes a dedicated portion for sustainability initiatives, addressing concerns around:
* Greenhouse Gas Emissions: reducing methane leakage and exploring options for carbon capture.
