Geophysics in Geothermal Exploration

21 The authors Éric LASNE Geologist with a PhD in hydrogeology, Éric Lasne has held project management and management positions at Compagnie Française de Géothermie since 1992. As such, he has extensive knowledge of the challenges of the subsoil in terms of all the applications and uses of geothermal resources. On the technical side, Éric Lasne has worked on several low-energy geothermal projects in France (Dogger in the Paris Basin, Aquitaine Basin, Alsace, Centre Region, etc.) and for electricity generation in the French overseas territories (Guadeloupe, Martinique, La Réunion) and abroad (Azores – Portugal, Dominica, Indonesia, China, Russia, etc.). Involved in the development of CFG’s activities, he is also active in professional organizations dedicated to the promotion and development of geothermal energy. A representative of one of the founding members of AFPG, Éric Lasne is also a member of the geothermal energy committee of the French Renewable Energy Union (SER). Vincent MAURER Dr Vincent Maurer is a senior geophysicist specialized in seismology with skills in design and installation of seismic networks for monitoring induced micro-seismicity. He was graduated in 2009 with a PhD on geophysics at ETH-Zürich in Switzerland. From 2010 to now, he worked for geothermal industry at Électricité de Strasbourg Géothermie (ÉSG) as a geophysicist and is responsible for the seismic monitoring of the Soultz-sous-Forêts and the Rittershoffen geothermal plants. In parallel, he is involved in many geophysical surveys for geothermal exploration in Alsace: 2D/3D seismic acquisition, 3D MT/CSEM survey, aeromagnetic and gravity campaigns, and passive seismology. He also contributed to the interpretation of the geophysical acquisition to design well trajectories. At ÉSG, he is currently involved in several industrial geothermal projects in Northern Alsace. He contributed to national R&D projects and EU research projects dealing with geothermal energy. He is author or co-author of many international scientific publications.
