Method and apparatus for communicating with downhole devices in a wellbore

摘要

A system for use in a well such as an intelligent completion system, includes an electrical cable and a plurality of communication modules positioned in the well. At least a first one of the communication modules is connected to the electrical cable. At least a second one of the communication modules is positioned in a remote location in the well past separately installed downhole equipment. A communications link mechanism that includes an inductive coupler mechanism provides communication between the first and second ones of the communication modules.
