Abstract

A signal transmission device transmits power and / or data between one or more surface devices and one or more downhole devices positioned in a wellbore. The signal transmission device includes at least one conductive element that electrically couples to one or more downhole devices and electrically couples at a surface end to the one or more surface devices. The conductive element is also coupled to the wellbore tubular to form a conductive circuit. The conductive element can also include a bore for conveying fluid from a surface source.
