Abstract
In one aspect, an apparatus for use in a wellbore is disclosed that may include a transmitter placed on an electrically-conductive member at a first location in the wellbore configured to induce electromagnetic waves that travel along an outside of the conduit and a receiver placed on the electrically-conductive member at a second distal location in the wellbore configured to detect the electromagnetic waves induced by the transmitter.
