CGG Releases White Paper on Potential of Offshore Geothermal Energy as a Future Global Resource

Paris, France | Feb 13, 2024

CGG, a global technology and Earth science leader, has released a white paper outlining the potential of offshore geothermal energy as a green energy resource of global significance and setting out a framework for its responsible development.

Research by CGG scientists strongly indicates the existence of vast, untapped geothermal resources along the magmatically active ocean floor spreading centers and adjacent flooded rift systems occurring in all the world’s major oceans. These offshore areas could be optimal locations to harvest geothermal resources for power in conjunction with the co-production of freshwater, Green Hydrogen, and ammonia, collectively creating an alternative set of rapidly scalable green energy solutions. CGG has a published patent application for a novel combination of geological, geophysical, and engineering technologies to support research into and the exploration, development and monitoring of offshore geothermal resources.

With more than 25 years’ experience using its multi-disciplinary geoscience expertise and technology to undertake projects across the geothermal value chain, CGG is well placed to responsibly identify and assess the most prospective and suitable offshore geothermal locations and work with partner organizations to develop these resources. More specifically, its global geothermal data curation expertise, industry-leading subsurface imaging technology, and geological interpretation capabilities leveraging machine learning will play a key role in optimizing offshore geothermal well placement and production.

Peter Whiting, EVP Geoscience, CGG, said:We strongly believe that geothermal energy as a baseload resource has a greater role to play in the future energy mix. The opportunity offshore geothermal resources present could be a game-changer in supporting the United Nations Development Programme’s 2023 Sustainable Development Goals including clean energy, climate action, and partnerships for sustainable development. While the patent application recognizes the exceptional work of our Geothermal experts, our motivation for seeking it is to ensure that there can be rapid, responsible, and equitable development of these resources. We are delighted to publish this white paper and I’m proud that CGG will play an active role in supporting the development of this important global resource.”
