ABSTRACT:
A technique is provided to control operation of well tools deployed in a wellbore. The technique utilizes a completion with at least one well tool actuated by fluid input. An electronic trigger system is associated with each well tool and is designed to respond to a unique series of pressure pulses. Upon receiving the unique series of pressure pulses, the electronic trigger system actuates to enable flow of actuating fluid to the well tool for operation of the well tool.
