An electrically stimulated electrode system 100 may comprise injection and return electrodes 110, 112 and a power supply 120 for causing electrical current to flow through a subterranean formation 104. An electronic system 200 for the injection electrode may include: a power harvester 210 for extracting electrical power from current flowing in the injection electrode, or a current control 300 for the current flowing through the injection electrode, or a sensor 400 of the injection electrode and/or the formation, or a telemetry 400 for receiving a parameter relating to the injection electrode and/or the formation, or any combination thereof. A sensor 210e, 400 may comprise: a pair of spaced apart electrodes 212e, a power conversion device 220 connected to the pair of spaced apart electrodes for providing electrical power, and a processor 420 for providing a representation of a current. The electronic system 100 may include: a power harvester 200, a commandable and/or programmable current control 300; and a control system 130, 400 for commanding and/or programming the current control, whereby the current flowing in the injection electrodes 110 may be independently controlled and/or sequenced in time. |
