The use of the subsurface as a thermal, electrical or material storage could alter the geological subsurface. The understanding of the impact is critical for a realisation of a subsurface storage.
The geophysical contribution includes:
- the description of the geological structure,
- the characterisation of geological units and faults and
- the development of a monitoring scheme for a thermal storage.
Several experiments were conducted:
- active seismic and geoelectrical measurements at to tests sites with possible faults
- geoelectrical and GPR measurements in labortory and in the GeoModel.
