Electrical methods
Often used in addition to the seismic methods that we deploy, the electrical methods make it possible to discriminate the electrical conductivity (or resistivity) contrasts of the materials of the subsoil and of the fluids present. By performing electrical resistivity tomography (ERT) and induced polarization (IP) acquisitions, we are able to analyze, interpret and integrate this data to provide added value to your projects.
Electrical resistivity tomography (ERT)
Allows you to identify and map the presence of possible contamination
Can be operated on long lines in remote or difficult to access areas
Ideal for depths 10 - 60m
Allows mapping of stratigraphic units
Induced polarization tomography (IP)
Allows to image the presence of conductors
Can be combined with electrical resistivity tomography in simultaneous measurements
Can be operated on long lines in remote or difficult to access areas
Spontaneous polarization (SP)
Maps the presence of a thermal gradient
Allows to identify areas of change in fluid pressure in the ground (ex: flow)
Ideally combined with other geophysical measurements
