Experimental studies on reactive transport processes in Enhanced Geothermal Systems (EGS)

Reactive transport processes are crucial in various geological settings, driving rock alteration, ore deposit formation, CO2 sequestration and Enhanced Geothermal Systems (EGS). In EGS, these processes, triggered by chemical stimulation, result in dynamic changes in mineral composition and petrophysical properties.
