Multiple control line travel joint with injection line capability

Abstract

A multiple control line travel joint is disclosed having at least one non-coiled, fluid control line and at least one internal control line, such as a hydraulic, electrical, or fiber optic control line. The fluid control line can include an upper control line that enters the travel joint at a top port and a lower control line that exits out a bottom port of the travel joint. The top port and bottom port can be fluidly coupled through a sealed chamber in the travel joint. The second control line can be coiled within the sealed chamber. As the travel joint expands and contracts, the sealed chamber expands and contracts while remaining sealed, maintaining sealed fluid coupling between the top port and the bottom port.

Dependencies are inferred from the claim text.
