Abstract
A system for deploying a power cable within a coiled tubing includes a power cable operable to power an electrical submersible pump, the power cable extendable through a coiled tubing. A plurality of anchor assemblies are spaced along a length of the power cable, each of the anchor assemblies secured to the power cable and having a gripping element. The gripping element is moveable between a retracted position and an extended position in response to an applied stimuli, wherein the gripping element is sized to engage an inner diameter surface of the coiled tubing when the gripping element is in the extended position.
Claims18
A system for deploying a power cable within a coiled tubing, the system comprising:
- a power cable operable to power an electrical submersible pump, the power cable extendable through a coiled tubing;
- a plurality of anchor assemblies spaced along a length of the power cable, each of the anchor assemblies secured to the power cable and having a gripping element;
- wherein
- the gripping element is moveable between a retracted position and an extended position in response to an applied stimuli applied to the gripping element, wherein the gripping element is sized to engage an inner diameter surface of the coiled tubing when the gripping element is in the extended position;
- and
- the gripping element includes a two way shape memory effect material.
A system for providing power to an electric submersible pump, the system comprising:
- a coiled tubing extending within a subterranean well;
- a power cable located within the coiled tubing;
- a plurality of anchor assemblies spaced along a length of the power cable, each of the anchor assemblies secured to the power cable with a split collar and having a gripping element;
- wherein
- the gripping element is secured to the split collar;
- the gripping element is moveable between a retracted position and an extended position in response to an applied stimuli applied to the gripping element, wherein the gripping element is sized to engage an inner diameter surface of the coiled tubing when the gripping element is in the extended position and to have a reduced outer diameter when the gripping element is in the retracted position;
- and
- the gripping element includes two way shape memory effect material.
A method for deploying a power cable within a coiled tubing, the method comprising:
- providing a power cable with a plurality of anchor assemblies spaced along a length of the power cable, each of the anchor assemblies secured to the power cable and having a gripping element that includes a two way shape memory effect material, wherein the power cable is operable to power an electrical submersible pump;
- extending the power cable through a coiled tubing;
- applying a stimuli to the two way shape memory effect material to move the gripping element radially outward from a retracted position to an extended position, so that the gripping element engages an inner diameter surface of the coiled tubing.
