Affordable gravity prospection calibrated on improved time-to-depth conversion of old seismic profiles for exploration of geothermal resources

The world energy strategy for a sustainable development promotes the use of renewable energies. Among them, middle-enthalpy geothermal energy may be used to supply heat to service industries and urban centres. However, the costs for the acquisition of high-resolution geophysical data are still high compared to the economical return of the energy eventually extracted. This study proposes a method applied to the Greater Geneva Basin, Western...
