ABSTRACT:
A method of suspending an electric submergible pumping system within a wellbore includes inserting an electric cable within a conduit, such as coiled tubing. One end of the conduit is sealed with one end of the electric cable extending out therefrom. The conduit is filled with a fluid of sufficient volume and sufficient density to float the electric cable within the conduit when the conduit is disposed within a wellbore. An electric submergible pumping system is connected to the conduit, and the electric cable is connected to an electric motor of the electric submergible pumping system. Thereafter, the electric submergible pumping system and the conduit are inserted into the wellbore. Since the cable is floating, i.e., self supporting, within the conduit there is no need for cable anchors or other devices to transfer the weight of the cable to the conduit.
