Abstract
A method and system for deploying electric submersible pumps in oil wells using reeled tubing, comprising providing reeled tubing (10), providing an electric submersible pump (20) and connecting it to one end of the reeled tubing (10), providing electric cable (22) and connecting one end of it to the electric submersible pump (20), aligning the electric cable (22) with the reeled tubing (10), using clamps (28) to attach the electrical cable (22) to the reeled tubing (10), inserting the electric submersible pump (20) into a wellbore (18), and injecting sufficient reeled tubing (10) and electrical cable (22) into the wellbore (18) to lower the electric submersible pump (20) to a desired level.
Claims6
A method for deploying an electric submersible pump on reeled tubing in a subterranean wall, said method comprising the steps of:
- providing reeled tubing;
- providing an electric submersible pump;
- operatively connecting the electric submersible pump to the reeled tubing;
- providing electrical cable;
- operatively connecting one end of the electrical cable to the electric submersible pump;
- aligning the electrical cable substantially parallel to the reeled tubing;
- attaching the electrical cable to the outside of the reeled tubing at a plurality of longitudinally spaced locations;
- inserting the electric submersible pump into a well bore;
- and injecting sufficient reeled tubing and electrical cable into the well bore to lower the electric submersible pump to a desired level.
A method for pumping liquids from a subterranean well, said method comprising the steps of:
- providing reeled tubing;
- providing an electric submersible pump;
- operatively connecting the electric submersible pump to the reeled tubing;
- providing electrical cable;
