Abstract
A technique is provided to facilitate gravel packing in a well. A conduit surrounded by a screen is deployed in an isolated lower wellbore region. The conduit cooperates with one or more valves that can be selectively opened to relieve wellbore pressure resulting from advancement of the beta wave during the gravel packing procedure. A control system enables dependable and timely opening of the one or more valves to relieve wellbore pressure and protect the surrounding formation.
