This PhD position is part of the MSCA Doctoral Network MiningBrines (https://miningbrines.eu/), which aims to develop sustainable strategies for the extraction and valorization of critical raw materials, energy gases, and geothermal energy from geothermal brines.
The research of this position focuses on assessing the impact of fluid extraction and CO₂ capture and reinjection on the thermo-hydro-mechanical and geochemical conditions of geothermal reservoirs in sedimentary basins. The work includes the development of integrated geological models, geochemical and petrophysical characterizations of the reservoir and brines, and numerical simulations to evaluate fluid flow, stress redistribution, and water–rock interaction processes.
The methodological approach used in this investigation combines field work, laboratory analyses, and numerical modelling. The candidate will benefit from secondments at partner institutions, including industrial partners, within an international and interdisciplinary research environment.
