<p>A control system for use in a subterranean well comprises at least one power generation device positioned within the subterranean well, the at least one power generation device adapted to supply electrical power to at least one apparatus positioned within the subterranean well and at least one control line positioned in the subterranean well. The at least one control line connects each power generation device to surface and is adapted to supply a hydraulic pressure applied from surface to the at least one power generation device from which the at least one power generation device generates the electrical power to be supplied to the at least one apparatus.</p> |
