Petrothermal Geothermics

Independent from the existing water volume petro-thermal systems take advantage of hot rocks acting as natural recuperators. According to the natural available water volume and in conjunction with the required flow volume additional water is pumped from the surface into the heat reservoir. Via a still existing or induced system of fractures and fissures the water flows to the production well which is being heated. After having flown through a plant on the surface the water is then returned into the rock body where it is re- heated.

In regard to the term petro-thermal systems it is distinguished between Enhanced Geothermal Systems (EGS) and Hot-Dry-Rock-Systems (HDR).


The prospection and exploration of natural resources comprises both the finding and specification of potential deposits. Precondition for the implementation of any prospection activities within a designated field is an exploration licence.
