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.

Abstract: A generating system or transmission system for imparting and transmitting electrical power onto a continuous long electrical conductor for use related to drilling and fluid piping operations. The transmission system may include a power generator/transmitter, voltage transformers, a movable transmission line including the rotational (tubing, piping, casing, liner hanger, drill string, etc.) a receiving circuit/receiver that may be tuned for impedance matching and a converting device to output the transmitted power at a predetermined voltage to be either used immediately by a power consuming device or to be stored in a energy harvesting array such as but not limited to batteries.
