Abstract
A wired tubular string includes a first joint having an axial bore, a box end, a pin end, a concentric inner conductor, and a concentric outer conductor; a second joint having an axial bore, a box end, a pin end, a concentric inner conductor and a concentric outer conductor; a joint-to-joint connection formed at the connection of the pin end of the second joint with the box end of the second joint; and an isolation assembly positioned at the joint-to-joint connection to operationally connect the corresponding concentric inner conductors and the correspond concentric outer conductor across the joint-to-joint connection and electrically isolate the inner conductor from the outer conductor.
