Underground Laboratories

Geothermal-Research-Platform Groß Schönebeck

The Geothermal Research Platform Groß Schönebeck is a reference laboratory for the development of geothermal technologies in hydrothermal reservoir rock with low permeability. Two research wells form a geothermal doublet and give access to water-bearing horizons at depths between 3,9 and 4,4 km at temperatures of 150 °C.

KTB Deep Crustal Lab

The KTB Deep Crustal Laboratory of GFZ Potsdam (KTB-DL) is a worldwide unique research site for a wide variety of experiments, tests and measurements under in-situ borehole conditions. The constellation of two very deep boreholes in crystalline rocks close to each other (200 m) with easy accessibility and full technical infrastructure allows deep borehole experiments at reasonable costs. The KTB site is located in Windischeschenbach, Oberpfalz, Bavaria in southeastern Germany.

GFZ-Underground-Lab Freiberg

The GFZ Underground-Lab in the research and education mine "Reiche Zeche" in Freiberg offers the possibility to run series of experiments to develop underground applications. With respect to the known geological background, market-ready systems can be realized.


The Operational Support Group of the International Continental Scientific Drilling Program, ICDP, situated at GFZ, provides downhole logging services and access to utilize the ICDP instrument pool for PIs of successful ICDP proposals.
