Glossary

Enhanced Geothermal Systems is a variant of petro-thermal geothermics. Subsurface water is found but its amount or the required rock permeability, essential for a sufficient water flow, is not adequate for geothermal exploitation. Stimulation activities artificially improve initial conditions for potential exploitation.

Within a designated exploration licence The Federal German Mining Law grants the exclusive right to prospect and explore natural resources to its holder. This right is initially temporary but it can be extended if there are no uniquely defined reasons contradicting the specifications of the Federal German Mining Law.
