Hydrogeology and Hydro-Geothermal Energy

Hybrid seismic surveying is optimally suited in the development of ground water resources in stratified aquifers and for the exploration of mineral and thermal water in jointed rock aquifers.

Key benefits

  • Multi-disciplinary geophysical characterization of the subsurface structures by using mechanical and electrical rock properties
  • Enhancement of the interpretation reliability due to minimization of ambiguities
  • Facilitates the positioning of boreholes and thereby reduces their number to a bare minimum
  • Recording two intersecting seismic lines prior to drilling a well provides valuable information about zones of higher permeability of the aquifer
  • Cost efficient measure for financial risk mitigation

Examples

Example 1: Prospection and protection of ground water in a stratified aquifer
