INPEX: Bonaparte CCS Joint Venture achieves robust appraisal results and progresses into pre-FEED to support a large-scale carbon capture and storage (CCS) project

The Bonaparte CCS Joint Venture (INPEX Browse E&P Pty Ltd 53% as Operator; TotalEnergies CCS Australia Pty Ltd 26%; and Woodside Energy Ltd 21%) announced it has commenced preliminary front-end engineering design (pre-FEED) work to support development of the Bonaparte CCS Project, located in the Bonaparte Basin, approximately 260 kilometres offshore Darwin, Australia. The Bonaparte CCS Joint Venture was formed in 2022 to appraise the awarded greenhouse gas storage assessment acreage (title G-7-AP). The decision to progress the project into pre-FEED follows the successful completion of both the selection of engineering concept and a comprehensive appraisal program, which included ~1,800 square kilometres of new three-dimensional seismic surveying and two carbon dioxide (CO2) storage appraisal wells. The appraisal program confirmed the presence of a high-quality saline aquifer reservoir in the Bonaparte Basin together with thick sealing formations considered suitable for safe and permanent long-term carbon storage.

INPEX Managing Director and Country Chair Australia Tetsu Murayama said achieving the Bonaparte CCS pre-FEED milestone is an important step towards a lower carbon future. “The Bonaparte CCS appraisal results are outstanding and have exceeded our expectations. The G-7-AP acreage is proving up to be one of the most promising CO2 storage sites globally. “Bonaparte CCS Joint Venture intends to transport and store CO2 safely and permanently offshore northern Australia in the Bonaparte Basin, which has a potential carbon storage capacity of more than 10 million tonnes per annum, with Ichthys Joint Venture expected to be the anchor customer.

“With a plan to commence CO2 injection around 2030, the proposed Bonaparte CCS project could substantially contribute to decarbonising northern Australia and potentially the wider Indo-Pacific region,” Mr Murayama said.

The Bonaparte CCS Assessment Joint Venture is now conducting detailed analysis of the reservoir appraisal data, to support a Declaration of Identified GHG Storage Formation application in advance of obtaining a greenhouse gas injection licence.
