Abstract

An apparatus for obtaining resistivity parameters of earth formations (7) uses capacitive coupling (5) for injecting measure currents into the formation through a nonconducting mud. In one embodiment, a modulated electrical current is used. Alternatively, multifrequency measurements may be made to obtain the resistivity parameter. In an optional embodiment, the modulation frequency is in the AF range, making it possible to use prior art circuitry designed to reduce cross talk. Measurements may be made either on a wireline or in a MWD configuration.
