Gorgon Carbon Dioxide Injection project
The Gorgon Carbon Dioxide injection project is an important part of the historically significant Gorgon Project, which will develop the Greater Gorgon Area gas fields off the northwest coast of Western Australia.
The Project is expected to be the largest long term carbon dioxide storage project in the world, and plans to inject about 3.3 to 4 million tonnes of carbon dioxide per year into a geological layer known as the Dupuy Formation, about 2.5 kilometres beneath Barrow Island. A range of monitoring, reservoir management and uncertainty management activities are planned to monitor the movement of carbon dioxide in the subsurface.
The project was granted approval by Premier Colin Barnett (as the Barrow Island Act Minister) on 14 September 2009. The Barrow Island Act 2003 (WA) was the first legislation regulating carbon dioxide storage (geosequestration) in the world.
In the lead up to the final approval of the project in 2009, the project arguably experienced the most stringent scrutiny of its kind. The Department of Mines and Petroleum, on behalf of the Western Australian Government, outsourced four phases of reviews for due diligence purposes. The due diligence teams, comprising international carbon capture and storage experts, highly praised the project proposal, and made many technical recommendations to be considered in the Gorgon Joint Venture’s ongoing work during the Phase III and Phase IV due diligence reviews.
A fifth due diligence review of the implementation of previous recommendations was completed in 2013. It concurred the majority of the recommendations from previous reviews were addressed adequately by the Gorgon Joint Venturers, and did not identify any concerns with the project that were not directly related to at least one of the previous recommendations.
The project started construction on 15 September 2009. The carbon dioxide injection wells were spudded in mid-2013, and injection operation is expected to be commissioned in the first half of 2017.
