Abstract
A system for deep deployment of electric submersible pumps is described. In an implementation, an electric submersible pump (ESP) power cable has a strength member that enables the ESP power cable to support itself when lowered deep into a well inside a coiled tubing. The self-supporting ESP power cable frees the coiled tubing from having to carry the weight of the ESP power cable, thereby permitting longer runs of coiled tubing to be suspended into the well. The ESP power cable and the coiled tubing can be anchored independently to a wellhead, and a computing device can monitor the weight loads on the ESP power cable and on the coiled tubing.
