SERVICES

The geophysics laboratory can provide services in various areas that include the design and execution of surveys and monitoring using geophysical techniques.

The geophysical methods available are:

  • seismic and tomographic both surface and borehole (DHT and CHT);
  • seismic for 1D, 2D and 3D surface waves;
  • georadar surveys on the ground or in surface waters;
  • electrical resistivity and chargeability tomographies on the surface and in the borehole;
  • electromagnetic measurements in the time domain (TDEM) and in frequency;
  • magnetometer measurements.

Data processing and inversion are conducted using state-of-the-art commercial codes and proprietary calculation codes that implement advanced methodologies resulting from the group's research activities.
