Abstract
A battery charging arrangement including a communication borehole having a conductive component, a subject borehole having a conductive component, a surface conductor electrically connecting the communication borehole and the subject borehole, an inducer of a voltage difference between the communication borehole and the subject borehole, a portion of a formation in which the communication borehole and the subject borehole are defined, having a resistivity conducive of creation of a circuit, and a battery in one of the communication or subject boreholes configured to be charged using current from the circuit. A method for charging a battery in a downhole environment including electrically connecting at least two boreholes to one another, inducing voltage in the boreholes, creating a circuit through the boreholes and through a portion of a formation, charging the battery with the circuit.
