Abstract
Systems and methods for wireless power transmission in a well, wherein first and second structural members of a well completion are electrically connected to form an electrical circuit, with first and second toroidal transformers positioned around the second structural member at different axial locations. A power source coupled to the first toroidal transformer is configured to generate an output voltage which is applied to the first toroidal transformer, inducing a corresponding electrical current in the electrical circuit. This in turn induces a second voltage on the second toroidal transformer, which is provided to a downhole tool. The tool may include conditioning circuitry, which rectifies the received power and charges a battery. The downhole electric tool is then operated using the received power.
