"ADAPTED SYSTEM FOR PROVIDING POWER FOR A WELL FUND DEVICE, OIL WELL FOR PRODUCING OIL PRODUCTS AND METHOD FOR POWERING A WELL BACKGROUND DEVICE". Oil well (20) for production of petroleum products incorporating a system adapted to power a wellbore device (50) in well (20). The system comprises a current impedance device (70) and a wellbore energy storage device (112). The current impedance device (70) is positioned such that when a time-varying current is transmitted through the portion of a pipe structure (30 and / or 40) a voltage potential between one side (81) is formed. ) of the current impedance device (70) and the other side (82) of the current impedance device (70). The device (112) is adapted to be electrically connected to the pipe structure (30 and / or 40) through the voltage potential formed by the current impedance device (70), and adapted to be recharged with the electric current, and is adapted to be electrically connected to the downhole device (50) to provide power to the downhole device (50) as required.
