TGS has entered into an agreement with deepC Store to carry out subsurface well location planning, storage resource verification and evaluation for carbon storage in the G-14-AP permit area in the Browse Basin, offshore Australia. The assessment will take place throughout 2025 on the permit, which is co-owned by deepC Store and Azuli (Australia). This collaboration marks a notable step in accelerating carbon capture and storage (CCS) initiatives in the Asia Pacific region, reinforcing Australia’s commitment to reducing carbon emissions and advancing sustainable energy solutions.

The G-14-AP permit is one of the two offshore CO₂ storage acreages awarded to deepC Store and Azuli by the Australian Commonwealth Government in August 2024, alongside the G13-AP permit. 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 (1 billion tonnes) in the permit area. The integration of TGS’ advanced subsurface data and deepC Store’s expertise in CCS project development will be essential in assessing the feasibility and long-term security of carbon storage in the Browse Basin.

Commenting on the contract award, TGS EVP New Energy Solutions, Will Ashby, said: “We are delighted to see our collaboration with deepC Store evolve into actionable projects and services, following the recent award of Carbon Storage acreage in Australia. We are eager to contribute TGS’ world-class expertise and advanced site characterisation services to this significant initiative. This project underscores Australia’s vast potential while reaffirming TGS’ commitment to supporting global climate goals and enabling CCS developers to make tangible progress.”

deepC Store’s Managing Director Daein Cha said: “We are very pleased to work with TGS for progressing one of its key technical activities for G-14-AP.  This relationship is an essential component of our world-class CO₂ storage development.  This work demonstrates our ongoing commitment to establish CStore1 as the first offshore floating CCS hub project in the Asia Pacific region, and to advance Australia’s strategic position in the CCS business.”
