Australia Greenhouse Gas Acreage Bid Rounds

TGS has been active in Australia since 1998, building up an extensive database that consists of 2D, 2Dcubed and 3D seismic data, gravity and magnetics data, and Facies Map Browsers. Our data can help identify carbon storage opportunities in GHG lease blocks.

2023 Australia GHG Lease Round Announced

The Offshore Petroleum and Greenhouse Gas Storage Act 2006 established a system to assess and permit areas for CO₂ storage, and three subsequent release rounds were held in  2009, 2014, and 2021. On August 28, 2023, following a request for nominations by the Australian government, additional prospective CO₂ storage areas were announced to potential bidders.

Final submissions for work-bid applications closed on November 28, 2023. Applicants were required to perform a detailed assessment of the work they would be performing to determine the suitability of each storage area. These assessments needed to contain all the proposed engineering enhancements for injection and assessments of the geological and geotechnical characteristics of the formations that may influence the storage potential of the reservoir. In addition to the technical evaluation concerning the storage potential of various formations within the lease area, the applicants were required to provide environmental assessments to mitigate any interference with fishing or other nautical navigation and propose strategies to conserve marine geography and ecology.
