Abstract
A discharge head for an electrical submersible pump allows the pump assembly to be supported on coiled tubing. The discharge head has a cable passage through which the power cable passes. A motor lead extends from the motor alongside the pump and to the discharge head. The discharge head has flow passages that are offset relative to the longitudinal axis of the discharge head. An annulus seal mounted to the discharge head seals the annulus surrounding the discharge head. A power cable extends through the coiled tubing in one embodiment and is strapped to the coiled tubing in another embodiment.
