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, before the conduit is deployed downhole. The electric cable is inserted into the conduit at the surface and is permitted to buckle in a manner so that the electric cable buckles and uniformly contacts an interior surface of the conduit at a plurality of locations along the entire length of coiled tubing to prevent longitudinal movement of the electric cable within the conduit. An electric submergible pumping system is then connected to the conduit, and the electric cable is connected to an electric motor of the electric submergible pumping system. The electric submergible pumping system and the conduit are inserted into the wellbore.

Description

CROSS REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit under 35 U.S.C. §119(e) of U.S. Provisional Patent Application Ser. No. 60 / 495,663, entitled “CONDUIT HAVING A CABLE THEREIN,” filed Aug. 15, 2003.BACKGROUND OF INVENTION [0002] The present invention relates generally to the field of cables, and more particularly to a device and method for providing a cable in a conduit. [0003] An electric submergible pump (ESP) may be suspended in a well from coiled tubing with an electric cable to power the pump inside the coiled tubing. Produced fluid is pumped up the casing to coiled tubing annulus. Since the electric power cable has low tensile strength, the length of power cable that can be freely suspended in inclined tubing is limited. Therefore, the cable may be clamped, banded or strapped to the outside of the tubing at intervals, as disclosed in U.S. Pat. No. 4,681,169, which is hereby incorporated herein by reference. Alternatively, the cable may be dispos...
