‘Where to drill the next well?’ and ‘How to operate a geothermal system in the most efficient and safe manner?’
These are the most important and urgent questions after a geothermal resource has been identified. The drilling success in geothermal systems can be enhanced through a better understanding of the subsurface. Here, the location of permeable fluid pathways is a key strategic step. Once the geothermal system is running, the sustainable operation is most essential also for the payback. The sustainability is mainly depending on the interaction between fluids, rocks and layout of powerplant components. Additionally, every geothermal project highly depends on the perception in the public. Factors influencing the perception are, among others, media and politics.
