Abstract
A system and method for providing redundant wired pipe-in-pipe telemetry is described. The redundant wired pip-in-pipe telemetry system includes an outer pipe and an inner pipe disposed within the outer pipe. Within the outer pipe, two or more conductive elements may be provided as well as a wired path controller that may selectably switch between available conductive paths. The wired path controller may identify conductive paths with good electrical characteristics and select those paths for transmission. If a conductive path develops a fault, the wired path controller may select one of the alternative redundant conductive paths for transmission to avoid the fault. The wireless controller may further transmit information about the location of faults to a drill operator at the surface.
