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 has now developed a test rig that simulates downhole conditions at several thousands of meters below the earth’s surface. This will make geothermal engineering more efficient.
