| Title of Invention | A SYSTEM TO PROVIDE POWER TO A DOWNHOLE DEVICE IN A PETROLEUM WELL |
|---|---|
| Abstract | The; present invention relates to a petroleum well (20) for producing petroleum products that incorporates a system adapted to provide power to a downhole device (50) in the well (20). The system comprises a current impedance device (70) and a downhole power storage device (112). The current impedance device (70) is positioned such that when a time -varying electrical current is transmitted through the portion of a piping structure (30 or 40) a voltage potential forms between one side (81) of the current impedance device (70) and another side (82) of the current impedance device (70). The device (112) is adapted to be electrically connected to the piping structure (30 or 40) across the voltage potential formed by the current impedance device (70) is adapted to be recharged by the electrical current and is adapted to be electrically connected to the downhole device (50) to provide power to the downhole device |
