The exploration risk for geothermal wells is high, as the desired flow rates can often not be achieved due to insufficient permeability of the rocks in production horizons. Processes are already known from the oil and gas industry that can in principle be used to increase the permeability of a reservoir.
However, the conditions, which are typical for oil and gas reservoirs, cannot simply be transferred to geothermal reservoirs. These are often formations of hard rock where the water jet technology used in the RJD process has no or too low drilling performance.
In the Micro Turbine Drilling (MTD) project, a method is to be developed with which the permeability can be increased even in very hard production horizons of geothermal wells. The solution is based on the principle of RJD. Preliminary tests carried out with functional prototypes confirm the basic functionality and thus the great potential of the technology.
