Large expectations are put on deep geothermal energy for electricity production in order to reduce fossil fuel consumption and curb greenhouse gas emissions.

However, we currently do not know how to properly engineer deep underground exchangers that are sufficiently productive over many years while being seismically safe.

Rock physics and mechanics can help us understand and constrain short- and long-term deformation in deep geothermal reservoirs. In particular, a good understanding of the thermo-hydro-mechanical couplings on the deformation processes operative within these reservoirs is of crucial importance for better reservoir production economics and safety. In this session, we invite novel contributions based on laboratory experiments, numerical modelling and field work (or a combination of these) covering (but not exclusive to) the following aspects of deep geothermal energy:

- New developments in hot reservoir characterization (measurements, interpretation techniques etc.)

- Transfer of technologies from oil and gas (completion systems, stimulation techniques etc.)

- Characterization and control of the induced seismicity risk

- Long term processes (chemistry, fluids & mechanics) and their importance for the economics of deep geothermal reservoirs production

- Thermo-hydro-mechanical couplings in reservoirs

We particularly welcome contributions from early career scientists.
