  • Geoelectrical surveys

    The measurement of electrical resistivity of the subsurface is one of the oldest geophysical methods (VES). It was developed during the late 1980s and the early 1990s as an electrical 2D and 3D imaging method for mapping the resistivity distribution in the subsurface CVES/ERT. Electrical resistivity is effective for shallow subsurface mapping at a ...
