Abstract : This project aims at assessing the feasibility of the CO2-DISSOLVED concept, combining injection of dissolved CO2 and recovery of the geothermal heat. The objective here was to identify and to quantify the thermo-hydro-geochemical processes induced by a massive injection of dissolved CO2 into a carbonated aquifer and a clastic reservoir. For that purpose, several simulations were performed using the MARTHE-PHREEQC and MARTHE-REACT reactive transport codes. Simulation results corroborate the expected great reactivity of the carbonated reservoir under the injection of CO2-rich brine. Numerical results provide new arguments confirming the feasibility of the CO2-DISSOLVED approach.
