  • What is Electrical Resistivity?

    2017-08-16 19:10:55

    The electrical resistivity method allows the determination of the spatial distribution of the resistive characteristics of the subsurface. This property is affected by lithology, pore fluid chemistry, and water content. The method can be ap...[more]

  • What is Electromagnetic method?

    2017-08-16 19:09:24

    Electromagnetic methods are sensitive to variations in electrical properties of subsurface materials and can map out regions with enhanced conductivity because of the presence of fluids, metals, or other variations. Electromagnetic inductio...[more]
