ABSTRACT:
A well control system for providing surface control of downhole production tools in a well. The well control system is capable of detecting well conditions and of generating command signals for operating one or more well tools. An electric conductor transmits electric signals, and a hydraulic line containing pressurized hydraulic fluid provides the power necessary to operate downhole tools. The invention provides a unique system for providing redundant conductors and redundant hydraulic lines to the well tool to continue operation if an electric conductor or hydraulic line becomes disabled. The well control tool also permits the selective operation of multiple production zones in a producing well.
