Gorgon Project development plan
Joint Venture comprising of Chevron 50%, Shell 25% and ExxonMobil 25%
3 x 5 MTPA LNG trains and a carbon dioxide injection project on Barrow Island
A domestic gas plant with capacity of 300 terajoules per day
LNG shipping facilities to transport products to international markets

The Gorgon Story
Situated 130 km off the North West Coast of Australia lies the Greater Gorgon Area
A world class resource containing more than 40 trillion cubic feet of gas – the equivalent of producing 6.7 billion barrels of oil
Gorgon is the modern-day equivalent of the Snowy Mountains Scheme
A long-term, technically-complex energy development that will mark a step-change and dramatic advancement of engineering
Barrow Island Class A nature reserve is the home of Gorgon and Australia’s oldest and largest onshore oilfield
Award-winning example of development co-existing with biodiversity protection

What is LNG?
LNG is Liquefied Natural Gas is natural gas (predominately methane, CH4), that has been chilled to make it easy to store or transport
When liquid, LNG takes about 1/600th the volume of its original volume
LNG is the cleanest burning carbon fuel

Carbon dioxide injection project
One of the world’s most greenhouse gas efficient LNG developments
Cutting-edge carbon capture and storage technology will create one of the world’s largest carbon dioxide injection reservoir
Project emissions expected to be reduced by approximately 40% (~3.4 MTPA CO2)
About A$2 billion investment

Australia’s largest subsea development
It will be the country’s largest subsea development
Subsea infrastructure will produce, gather and transport reservoir fluids from the fields to Barrow Island
Up to 30 subsea wells will be drilled in water depths from 200 to 1,350 metres
Once complete, there will be more than 180 kilometres of carbon steel pipeline laid and 12 kilometres of onshore line to the LNG Plant
Pipelines from Jansz-Io will cross an underwater escarpment that rises several hundred metres on the way to Barrow Island

Modularisation
Project is working hard to ensure that opportunities for local contractors are realised
The Industry Capability Network of Western Australia (ICNWA) provides an important interface to Australian industry
The modularisation will be similar to the North West Shelf Train 5 Project but involve many more modules
Up to 150,000 tonnes of module packages
Largest module about 7,000 tonnes

Gorgon Fast Facts
1,000 pieces of major equipment for the downstream facilities
2,100 kilometres of electrical and instrument cable
50 modules, the heaviest of which weighs 7,000 tonnes
2 LNG storage tanks with 180,000 cubic metres capacity
4 condensate tanks with 35,000 cubic metres capacity
120 million tonnes of carbon dioxide to be sequestered

Gorgon’s economic impact
The $43 billion Project is the biggest ever single private sector construction investment in Australia.
Greater initial investment than total North West Shelf Venture
ACIL Tasman study found in the first 30 years Gorgon will deliver:
Peak direct and indirect construction employment in WA of ~10,000 with more than 3,500 direct and indirect jobs sustained throughout the life of the Project
Around $33 billion (today’s dollars) flowing to locally purchased goods ands services
Boost to Australia’s GDP of $64 billion Government revenue of ~$40 billion (today’s dollars)
Gorgon’s massive infrastructure and investment will transform WA into a SE Asian regional petroleum service hub
