Del Ghianda 5.1 Context In a context of energy transition to limit greenhouse gas emissions, which have a deleterious effect on the climate, geothermal energy is playing an important role on the energy scene. After decades of development, operating technologies are now well mastered. However, one of the main obstacles to the development of this sector remains the investment cost, which can be broken down into several phases, including the discovery of a sufficient and sustainable thermal resource, the installation of the production plant, and its monitoring and maintenance. Locating a suitable and sustainable source of heat in the subsoil involves a high degree of geological risk and uncertainty. Geological risk, i.e. the risk of incorrectly positioning a borehole due to a lack of information about the subsoil and its properties, can be reduced by geophysical surveys that are suitably selected according to the geological context © EDP Sciences, 2025 DOI: https://doi.org/10.1051/978-2-7598-3752-6.c005
