Geophysical Resistivity Survey-Vertical Electrical Sounding

- Nov 25, 2019-


A Vertical electrical sounding (or VES) is a 1D resistivity method that provides deep information of the subsurface with minimal equipment and personnel. It is one of the oldest methods for acquiring resistivity and one of the least expensive to conduct per unit depth.


Vertical Electrical Sounding (VES) was the dominant geophysical resistivity method. It has been used all over the world for three primary purposes: geotechnical investigation, groundwater exploration, and mineral exploration.


VES applications:

  • Aquifer description

  • Bedrock depth

  • Mapping geological boundaries

  • Identification of fractures in the bedrock

  • Mapping of sand and gravel deposits

  • Sol / Strate unconsolidated

  • Mineral Exploration

  • Geological mapping

  • Mapping groundwater depth

  • Mapping spots brine

  • Groundwater Contamination

  • Inorganic pollutants leak detection

  • Leaking landfill

  • Maps of saline soils

  • Identify wells

  • Old settlements

  • Depth mapping rocks
