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. ## Claims ### Claim 1 A redundant wired telemetry system, comprising: an outer pipe; an inner pipe disposed within the outer pipe, wherein the outer pipe axially supports the inner pipe; a first conductive element coupled to the inner pipe and disposed within an annulus between the inner pipe and the outer pipe; and a second conductive element disposed within the outer pipe. ### Claim 2 (depends on 1) The redundant wired telemetry system of claim 1, further comprising a wired path controller coupled to at least one of the first conductive element and the second conductive element. ### Claim 3 (depends on 2) The redundant wired telemetry system of claim 2, wherein the first conductive element comprises a first upper portion and a first lower portion; and the second conductive element comprises a second upper portion and a second lower portion. ### Claim 4 (depends on 3) The redundant wired telemetry system of claim 3, further comprising a first signal pathway through the wired path controller. ### Claim 5 (depends on 4) The redundant wired telemetry system of claim 4, wherein the first signal pathway comprises one of the following combinations: the first upper portion and the first lower portion; the second upper portion and the second lower portion; the first upper portion and the second lower portion; and the second upper portion and the first lower portion. ### Claim 6 (depends on 4) The redundant wired telemetry system of claim 4, further comprising a second signal pathway through the wired path controller. ### Claim 7 (depends on 6) The redundant wired telemetry system of claim 6, wherein the wired path controller includes a switch that selects at least one of the first signal pathway and the second signal pathway. ### Claim 8 (depends on 7) The redundant wired telemetry system of claim 7, wherein the wired path controller selectably switches between the first signal pathway and the second signal pathway in response to a fault in one of the first upper portion, the second upper portion, the first lower portion, and the second lower portion. ### Claim 9 (depends on 2) The redundant wired telemetry system of claim 2, wherein the wired path controller includes a signal repeater. ### Claim 10 (depends on 1) The redundant wired telemetry system of claim 1, further comprising a third conductive element disposed within the outer pipe. ### Claim 11 A method for redundant wired pipe-in-pipe telemetry, comprising: introducing an outer pipe into a borehole; positioning an inner pipe within the outer pipe, wherein the outer pipe axially supports the inner pipe; coupling a first conductive element to the inner pipe, wherein the first conductive element is disposed within an annulus between the inner pipe and the outer pipe; coupling a second conductive element to the outer pipe, wherein the second conductive element is disposed proximate to the outer pipe; and transmitting telemetry data through at least one of the first and second conductive element. ### Claim 12 (depends on 11) The method of claim 11, further comprising providing a wired path controller coupled to at least one of the first conductive element and the second conductive element. ### Claim 13 (depends on 12) The method of claim 12, further comprising detecting faults in at least one of the first and second conductive elements using the wired path controller. ### Claim 14 (depends on 13) The method of claim 13, further comprising switchably selecting between the first and second conductive elements using the wired path controller. ### Claim 15 (depends on 14) The method of claim 14, wherein the wired path controller may switchably select the first and second conductive elements as parallel conductive paths. ### Claim 16 (depends on 13) The method of claim 13, further comprising transmitting information about the location of faults to an operator. ### Claim 17 (depends on 16) The method of claim 16, further comprising assigning the wired path controller a network identification number. ### Claim 18 (depends on 12) The method of claim 12, wherein the wired path controller includes a signal repeater. ### Claim 19 (depends on 11) The method of claim 11, further comprising providing a third conductive element within the outer pipe. ### Claim 20 A wired telemetry system, comprising: an outer pipe, wherein the outer pipe comprises a shoulder disposed on an inner surface; an inner pipe disposed within the outer pipe, wherein the inner pipe comprises a projection that is axially supported by the shoulder; a first conductive element coupled to the inner pipe and disposed within an annulus between the inner pipe and the outer pipe; and a second conductive element disposed within the outer pipe.
