Geothermal energy: Fraunhofer IEG operates simulator for drilling at depths up to 5,000 meters

Research News / October 01, 2020

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. Analyzing these experiments enables operators to optimize drilling during the planning and the operating stage and helps them develop and test new drilling tools, thus minimizing costs and economic risks. This will make geothermal engineering more efficient, helping to accelerate the transition to a new, sustainable energy economy.
