Abstract:
1. A method of coupling segments of a borehole conduit comprising: positioning a first conduit segment at a location selected from a surface location and a downhole location, the first conduit segment having a first end and a second end, the first conduit segment including a first connector at the first end and a second connector at the second end, the first connector being a pin connector, and the first conduit segment including a communication conduit extending within a metal body of the first conduit segment along a length of the first conduit segment between the first connector and the second connector, the communication conduit configured to provide protection for a conductor extending between the first connector and the second connector; orienting the first conduit segment so that the first end is located uphole relative to the second end; and coupling a second conduit segment in operable communication with the first conduit segment, the second conduit segment having a box connector at an end of the second conduit segment that is configured to engage the pin connector of the first conduit segment, one of the pin connector and the box connector including a first transmission element mounted on an outer surface of the pin connector or the box connector and the other of the pin connector and the box connector including a second transmission element located in a recess of the pin connector or box connector, such that coupling the second conduit segment with the first conduit segment inserts the first transmission element of the one of the pin connector or the box connector into the recess of the other of the pin connector or box connector.
