Influence of pore water on the heat mining performance of supercritical CO2 injected for geothermal development

Utilization of supercritical CO2 as heat transmission fluid for geothermal development associated with geological storage can achieve the double wins of economic benefits and environmental protection. The advantages of supercritical CO2 in thermodynamics and injectivity have been recognized widely. The main concerns of this technology are focused on the water production process at the beginning of CO2 injection and the long-term complicated...
