A system for use in hydrocarbon recovery from a well, the system comprising a downhole electrical device for use in hydrocarbon recovery, the downhole electrical device disposed downhole in the well, an amplifier coupled to a frequency resonator which is coupled to a pipe extending downhole in the well to provide electrical energy via resonant frequency utilizing the pipe, wherein the pipe is electrically isolated from a ground, a resonator coil coupled to the pipe, and a receiver and a pickup coil coupled to the downhole electrical device. The receiver receives the electrical energy transmitted through the pipe by resonant inductive coupling of the resonator coil with the receiver and the pickup coil is utilized to convert the electrical energy into current to power the downhole electrical device. |
