Abstract
A completion system for use in the well includes a liner for lining the well, where the liner has a first inductive coupler portion. An electric cable extends outside an inner passage of the liner. The completion system further includes a second inductive coupler portion and an electrical device inside the liner and electrically connected to the second inductive coupler portion. The first and second inductive coupler portions enable power to be provided from the electric cable outside the inner passage of the liner to the electrical device inside the liner.
Claims8
A completion system for use in a well, comprising:
- a liner for lining the well, the liner having a first inductive coupler portion;
- an electric cable extending outside an inner passage of the liner;
- a second inductive coupler portion;
- and
- an electrical device inside the liner and electrically connected to the second inductive coupler portion,
- wherein the second inductive coupler portion is positioned proximate the first inductive coupler portion to enable power to be provided from the electric cable outside the inner passage of the liner to the electrical device inside the liner;
- and
- wherein the liner has a housing in which a longitudinal conduit is embedded, wherein the electric cable extends through the longitudinal conduit.
A completion system for use in a well, comprising:
- a tubing to provide flow of fluid to or from an earth surface from which the well extends, wherein the tubing has a housing defining a longitudinal bore embedded in the housing;
- an electric cable in the longitudinal bore;
- an electrical device for positioning in the well;
- and
- an inductive coupler to communicate electrical energy between the electric cable and the electrical device.
