Abstract
In one aspect of the present invention, an induction resistivity tool incorporated into a downhole tool string component comprises an annular radial recess disposed along an outside surface of a tubular wall of the downhole component. At least one electrically insulated induction coil is disposed in the radial recess and adapted to transceive induction signals outward from the tubular wall when carrying an electrical current. The at least one coil is tuned for an optimal signal frequency and an actuator in the downhole component is adapted to put an electrically conductive element into and out of electrical contact with the at least one coil and thereby change the optimal signal frequency.
