| Abstract | As part of a geothermal project lead by ‘Électricité de Strasbourg’, a preliminary survey of seismic reflection was acquired during summer 2015 in the suburbs of Strasbourg area (Alsace, France). In addition, several other geophysical methods have been applied recently. A gravimetric survey was achieved in 2013 with the acquisition of 250 new measure points and during summer 2015, an aeromagnetic campaign, using a helicopter equipped with a magnetometer, was carried out over the same area. All the collected data were initially independently processed to determine sub-soil characteristics and to locate the optimal target for a new geothermal project. The future joint interpretation of these data will lead to an exploration guidance using all these geophysical measurements. |
