Abstract
The disclosed embodiments include gravel pack assemblies, method to bypass a fluid restrictor during gravel packing operations, and methods to control fluid flow during and after gravel packing operations. In one embodiment, a gravel pack assembly including a flow restrictor that is coupled to a downhole string that is deployed in a borehole is disclosed. The flow restrictor forms a first fluid passageway from the borehole to an internal cavity of the string. The gravel pack assembly includes a fluid bypass portion having a first chamber, a sealing member inserted into the first chamber; and an actuation assembly operable to actuate the sealing member. The fluid bypass portion forms a second fluid passageway from the borehole to the internal cavity of the downhole string prior to actuation of the actuation assembly. After actuation of the actuation assembly, fluid flow through the second fluid passageway is restricted by the sealing member.
