Abstract:
1. A communications module for downhole operations along a completion interval of a wellbore, comprising: an inner mandrel; at least one alternate flow channel along the inner mandrel to provide a route for gravel slurry to partially bypass the communications module during a gravel packing operation and enable gravel packing below the communications module; a transmitter-receiver for (i) receiving a signal, and (ii) in response to the received signal, sending a separate instruction signal; an electrical circuit programmed to (i) receive a signal and, in response to the received signal, deliver an actuating command signal; and a control line configured to reside entirely within the completion interval of the wellbore, the control line conveying the actuating command signal provided by the electrical circuit; wherein the communications module is configured to connect to a tubular joint in a wellbore.
