Abstract:
1. A control system for use in a subterranean well, the system comprising: a control line within the subterranean well; a hydraulic line within the subterranean well; a power generation device positioned within the subterranean well, the power generation device being configured to receive hydraulic pressure applied from surface via at least one of the control line and the hydraulic line and to generate electrical power from the applied hydraulic pressure; and an electrically activated valve positioned within the subterranean well, wherein the electrically activated valve is adapted to receive electrical power generated by the power generation device thereby enabling the valve to selectively allow hydraulic pressure to be applied via the hydraulic line to a hydraulically activated downhole tool positioned within the subterranean well for the selective operation of the downhole tool.
