Pushing the limits of geothermal deep drilling
Exploring the potential of high-temperature hydrothermal systems in Iceland
A conventional geothermal production utillizes „only“ the uppermost parts of the geothermal systems. A typical depth of a geothermal well is around 2.5 km and the temperature of the formation is around 240°C–330°C and the fluid there is at boiling point curve in the hottest part of the system. The deeper parts of the geothermal systems are not well known. Direct measurements are only available from the uppermost 2-3 km of the formation where wells have been drilled. One can however assume that there is a lot of hot rocks below the conventional system and beeing able to mine the heat from there would make huge resources available for power production.
