Abstract
A system and method for determining material resistivity. A current of one or more frequencies is generated using a circuitry. The one or more frequencies is directed using one or more electrodes into a surround-ing material. The resistivity of the material surrounding the electrodes and a drilling tool is measured by detecting the current at the one or more fre-quencies.
