Modelling of geological subsurface utilization in terms of chemical or thermal energy storage as well as hydrocarbon production and storage are required to ensure a safe and sustainable energy supply. Utilization of the geological subsurface, however, may induce changes in the recent hydraulic, thermal, mechanical and chemical regimes. Our session aims at the integration of experimental and numerical modelling methods for quantification and prediction of the potential impacts resulting from geological subsurface utilization including:

• Site characterization and determination of site-specific geological and process data.

• Development of static geological models.

• Integration of experimental data into static and dynamic models as well as application of numerical models for experimental design and interpretation.

• Development and benchmarking of modelling tools.

• Model and parameter upscaling techniques.

• Model coupling addressing the interaction of thermal, multi-phase flow, geochemical and geomechanical processes in the fluid-rock system.

• Application of modelling tools for site characterization and prediction of potential impacts.

• Methods for risk assessment and efficient site operation.
