HIGH FREQUENCY OR MULTIFREQUENCY RESISTIVITY TOOL

摘要

A system and method for determining material resistivity. A current of one or more frequencies is generated using a circuitry (225). The one or more frequencies is directed using one or more electrodes (215) into a surrounding material. The resistivity of the material surrounding the electrodes (215) and a drilling tool (210) is measured by detecting the current at the one or more frequencies.
