Abstract
A petroleum well for producing petroleum products that incorporates a system adapted to provide power to a downhole device in the well. The system includes a current impedance device and a downhole power storage device. The current impedance device is positioned such that when a time-varying electrical current is transmitted through the portion of a piping structure and/or a voltage potential forms between one side of the current impedance device and another side of the current impedance device. The device is adapted to be electrically connected to the piping structure and/or across the voltage potential formed by the current impedance device, is adapted to be recharged by the electrical current, and is adapted to be electrically connected to the downhole device to provide power to the downhole device as needed.
