Abstract
A method for two-way communication for controlling production from a formation having at least one producing well and a plurality of producing zones. In one embodiment, the method comprises installing a flow control device with a controller proximate each of the producing zones, where each controller has a predetermined communication address, and each controller is adapted to act as a repeater on command from a surface controller; connecting each controller to a transmission bus where the transmission bus is connected to the surface controller; transmitting a command message from the surface controller to a predetermined downhole controller, where the command message determines a predetermined path along the transmission bus according to a predetermined protocol; receiving the command message by the predetermined controller; and executing the command message to control the flow control device. Transmitting a response message back along the predetermined path.
