Apparat og fremgangsmåte for bestemmelse og avbilding av borehullsresistivitet ved å anvende kapasitiv kopling

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 o...
