  • Coal Exploration and Geophysical Logging, with Insitu

    Logging through the rods has been done since 1976 when advances in tool design reduced the size of these tools. Logging open hole before that carried with it a risk of loosing an expensive tool and a radio active source down the hole. There are no problems with logging through the rods. A geophysical log provides a graphic profile of a coal seam.

    Many methods used a century ago are still in use, but with the addition of refinements. So looking at how large and small deposits were found will change over time. (Simple example of that would be that Romans and their contemporaries didn't use geophysics, but they did find major copper deposits in Spain.) Deposits are getting harder to find.

  • Resistivity

    Consider current flowing through the unit cube of material shown to the right: resistivity is defined as the voltage measured across a unit cube's length (Volts per metre, or V/m) divided by the current flowing through the unit cube's cross sectional area (Amps per meter squared, or A/m 2). This results in units of Ohm-m 2 /m or Ohm-m.
