Abstract
Abstract A coiled tubing system deploys an electric submergible pump system within a wellbore. The coiled tubing system includes an internal power cable for providing power to a submergible motor. Additionally, a control line, such as a hydraulic line, is disposed within the hollow interior of the coiled tubing to provide an input to the submergible pumping system. The control line is preferably routed through an interior space of a connector unit disposed between the coiled tubing and the submergible motor.
