Contribution of the geothermal deep boreholes of the Soultz-sous-Forêts to the understanding of the reservoir and its exploitation

Abstract : The European experimental project of Soultz was initiated in 1984(Gérard et al., 1984)with the oil and gas crisis which was allow to develop renewable energy and new exploitation concepts. The pilot plantaims to exploit the potential energy of the deep fractured graniteto produce electricity.Based on this site, 30 years of research have permitted to better understand the deep geothermal system and gradually evolve the deep geothermal conceptual model.
