• Borehole Camera and Water Well Camera

    DefinitionPrimarily found in Oil & Gas and Mining applications, Borehole Cameras are meant to cover long distances. Borehole Cameras usually come on a spool or a reel, as Insertion Tube or Insertion Probe lengths can exceed hundreds of meters. Closely related to Drain Cameras, Pipe Cameras, or Sewer

  • Electrical resistivity tomography (ERT)

    Electrical resistivity tomography (ERT) or electrical resistivity imaging (ERI) is a geophysical technique for imaging sub-surface structures from electrical resistivity measurements made at the surface, or by electrodes in one or more boreholes. Electrical Resistivity Tomography (ERT) is an advance

  • Induced Polarization (IP)

    Induced Polarization (IP) is a geophysical method used extensively in mineral exploration and mine operations. The IP survey is very similar to electrical resistivity tomography (ERT). Resistivity and IP methods are often applied on the ground surface using multiple four-electrode sites. In an IP s

  • Electrical Resistivity Measurements in the field

    The resistivity of homogeneous, isotropic ground that would give the same voltage-current relationship as measured.
