Geological media are a strategic resource for the forthcoming energy transition and their use for geo-energy technologies is increasing to mitigate the adverse effects of climate change. Subsurface engineering applications such as deep geothermal resource exploitation, Carbon Capture and Sequestration (CCS), natural gas or hydrogen storage, involve multi-physical processes in the porous and fractured rock, including fluid flow, solute and heat transport, rock deformation and geochemical reactions, which occur simultaneously and impact each other. The safe and efficient deployment of such geo-energy technologies is bounded to the adequate understanding of these coupled thermo-hydro-mechanical-chemical (THMC) processes, and predictive capabilities heavily rely on the quality of the integration between the input data (laboratory and field evidence) and the mathematical models describing the evolution of the multi-physical systems.
This session is dedicated to studies investigating some of these THMC interactions by means of mathematical, experimental, numerical, data-driven and artificial intelligence methods, as well as studies focused on laboratory characterization and on gathering and interpreting in-situ geological and geophysical evidence of the multi-physical behavior of rocks. Welcomed contributions include approaches covering applications of carbon capture and storage (CCS), geothermal systems, gas storage, energy storage, mining, reservoir management, reservoir stimulation, fluid injection-induced seismicity and radioactive waste storage.
