Simulator for drilling at depths up to 5,000 meters

To tap into geothermal reservoirs, boreholes must be drilled deeply into the earth's crust. Due to the extreme pressures and temperatures involved, this is expensive and time consuming. A research team from Fraunhofer IEG ...

Taking the temperature of deep geothermal reservoirs

(Phys.org) —A lot can happen to water as it rises to the surface from deep underground. It can mix with groundwater, for example. This makes it difficult for scientists to estimate the temperature of a geothermal reservoir, ...

Intelligent use of the Earth's heat

Geothermal energy is increasingly contributing to the power supply world wide. Iceland is world-leader in expanding development of geothermal utilization: in recent years the annual power supply here doubled to more than ...
