Energy intelligence provider TGS entered an agreement with deepC Store Pty Ltd. to carry out subsurface well location planning, storage resource verification and evaluation for carbon storage in the Browse Basin offshore Australia.

The assessment in the G-14-AP permit area will take place throughout 2025 on the permit, which is co-owned by deepC Store and Azuli (Australia) Ltd., according to a Feb. 13 press release.  

The G-14-AP permit is one of the two offshore CO2 storage acreages awarded to deepC Store and Azuli by the Australian government in August 2024.

deepC Store serves as the designated operator of the G-14-AP permit and the associated CStore1 project, with an estimated CO2 storage potential of approximately 1 gigatonne in the permit area, TGS said.

The agreement works to establish CStore1 as the first offshore floating carbon capture and storage hub in the Asia Pacific region, said deepC Store’s managing director Daein Cha.
