In order to access and extract this energy, drilling of deep wells connected with vast financial investments is unavoidable. Thorough predrilling exploration followed by simulations of heat extraction can help to assess the site’s geothermal energy potential and thus lower the risk of possible financial losses. Extraction of heat enclosed in the deep rock can be simulated with a two-well geothermal system. Through one of the wells cool water is being injected into the reservoir, where it is heating up while travelling towards the production well. If certain conditions are fulfilled, water pumped to the surface carries the amount of energy sufficient for geothermal power production. With simulations of such geothermal systems it is possible to predict their profitability and sustainability. The extensive amount of scientific experiments performed during the Continental Deep Drilling Program (KTB) within the years 1985-1996 yielded a wide database of miscellaneous information concerning the continental crystalline crust. This and the fact that temperatures up to 265°C were measured in the KTB drill hole were the motives to choose the KTB site as case study representative for geothermal reservoirs located in crystalline environments.
