Within the framework of SCCER and in agreement with the Swiss plan for the sustainable development of renewable energies this project will generate innovative ideas for geothermal reservoir stimulation, provide a quantitative understanding of geothermal resources in the Great Geneva Basin and test cost-effective geophysical exploration methods for geothermal systems. GENERATE proposes an interdisciplinary work-package articulating around the hypothesis that incoming seismic energy with specific central frequencies may affect pore pressures in the reservoir unclogging pore throats and ultimately allowing a more effective fluid flow at depth. To achieve this goal GENERATE asks funding to support two PhD studentships, two PostDoc positions and instrumentation.GENERATE proposes to combine numerical simulations and geophysical methods with the ultimate goals of assessing the geothermal potential of the Great Geneva Basin and identifying target areas for drilling. GENERATE will focus on the Canton of Geneva and will use the natural laboratory of the Rio Sucio Fault System, Costa Rica, as a proxy to asses the effects of incoming seismic waves (i.e. seismic external forcing) on geothermal systems. The acquired knowledge will be fundamental for a better understanding and optimization of the Swiss study case.The Great Geneva Basin is characterized by a moderate heat flow but the advanced geophysical exploration conducted in the area represents an unprecedented geological and geophysical basis for the development of a geothermal assessment of the area. In this framework GENERATE will advance research and development by addressing four specific major questions:- Is it possible to build a large-scale fluid flow model of the Great Geneva Basin to quantitatively assess the geothermal potential of the area?- Is it possible to stimulate a geothermal system (i.e. the Great Geneva Basin) by means of seismic energy?- What is the nature of the interaction between passing seismic waves and induced heat and mass transport?- Is it possible to use passive seismic methods as a reliable and cost-effective technique for the exploration of a geothermal system?These questions will be addressed by four complementary projects, which will answer more specific problems for both the short- and long-term planning. GENERATE follows SCCER’s philosophy and has the potential to produce applied and fundamental findings while delivering novel research across various disciplines of earth sciences. Most notably, GENERATE will provide an important contribution for the development of geothermal energy in Switzerland.
