Supercritical Geothermal Systems - A Review of Past Studies and Ongoing Research Activities
International audience Supercritical geothermal systems are very high temperature geothermal systems that are located at depths near or below the brittle-ductile transition zone in the crust where the reservoir fluid is assumed to be in the supercritical state, e.g., for pure water temperature and p...

International audience Supercritical geothermal systems are very high temperature geothermal systems that are located at depths near or below the brittle-ductile transition zone in the crust where the reservoir fluid is assumed to be in the supercritical state, e.g., for pure water temperature and pressure are respectively in excess of 374°C and 221 bar. These systems have garnered attention in recent years as a possible type of unconventional geothermal resource that could yield much higher well productivities due to their very high enthalpy fluids. Supercritical conditions are often found at the roots of volcanic-hosted hydrothermal systems.
