The Gorgon LNG Project off the north-west coast of Western Australia will include what could be one of the world’s largest carbon capture and storage projects. Operator Chevron and its partners ExxonMobil and Shell received state approvals and licences for the overall project – which has an estimated lifespan of at least 40 years – in September 2009.

The commercial-scale CCS demonstration project will capture and store between 3.4 and 4 million tonnes of CO2 per year – a total of 120 million tonnes over the project’s lifetime, and 40 per cent of its emissions. When completed, the Gorgon and Collie South West CO2 Hub projects will have a combined potential to store more than eight million tonnes of CO2 per annum, or around 11% of Western Australia's annual current emissions.

The CO2 will be captured directly from the gas field before being liquefied and transported by 7km pipeline to the injection site, the Dupuy saline aquifer 2.3 km beneath Barrow Island. It was announced in October 2012, that the project was on track to begin CO2 injection in 2015, with nine injection wells expected to be drilled. The project includes long-term monitoring of the stored CO2 via a number of surveillance wells and repeated seismic surveying.

In October 2010, the Gorgon project was formally recognised by international agency, the Carbon Sequestration Leadership Forum, at its annual meeting in Warsaw, Poland. It is one of just six CCS projects worldwide currently under construction, and satisfies the seven criteria established by the G8 nations to assess whether the goal of having 20 CCS projects in operation by 2020 is achievable.

The Gorgon project operates under a State Agreement Act as there was no greenhouse gas storage legislation at the time of its development.


The overall cost of the first phase of Gorgon LNG is A$43 billion. The Gorgon Carbon Dioxide Injection Project represents an investment of about A$2 billion. In November 2006, the Australian government announced funding support of A$60 million from its Low Emissions Technology Demonstration Fund (LETDF) for the CCS part of the project. The FID was made in September 2009.

Since 2003, the venture has invested over AU$150 million in storage appraisal. This included drilling a data well, extensive well testing and acquisition of a new 3D seismic survey.


The project is well into a five-year construction programme, with first gas scheduled for 2016, according to Shell. Data wells have been drilled and a major sub-surface study has been carried out. One of the first contracts to be awarded was for the detailed design, construction and assurance testing of six CO2 injection compressor trains at a cost of AU$415 million. The first compressor module is due to arrive on Barrow Island in the second half of 2013.
