In this project, the Mauerstätten drilling will be used as a test environment for the further development of the novel BMWi-funded drilling technology "Micro Turbine Drilling - MTD". This method allows for cost-effective long, small-diameter deflection drilling from an existing cased/uncased borehole into hard rock formations, thereby increasing permeability in cases of insufficient productivity and minimizing the risk of finding productive zones. This technology will create entirely new opportunities for geothermal resource development and has generated significant interest in the industry.
