Zusammenfassung: | A system is provided for providing power and/or communication to/from a downhole device by inductively coupling a coupling conductor within a receiver to a core conductor of a tubing encased conductor (TEC). The receiver has an elongated housing arranged physically proximate or touching an outer surface of the TEC. A coupling conductor is disposed within the housing, extends substantially parallel to a longitudinal axis of the housing, and further extends longitudinally and in close proximity to a core conductor housed within the TEC when the housing is arranged physically proximate or touching the outer surface of the TEC. This exposes the coupling conductor to a magnetic field formed externally to the TEC to excite a current in the coupling conductor. In one or more embodiments, the receiver further includes a coupling to electrically couple the downhole device to the coupling conductor and deliver the current to the downhole device. |
