What is resistivity ?

Resistivity surveying has proven to be one of the most useful geophysical techniques. It is widely and successfully employed in groundwater investigation, mineral exploration and engineering studies.

In most cases, simple interpretation methods enable to deduct the number, thickness and electrical resistivity of the miscellaneous subusurface layers. These elements provide key information to determine the nature of these layers.
