Abstract:
A flow control assembly includes a cylindrical body that defines an interior and openings provided through a wall of the body. An inner sleeve is positioned within the interior of the body and defines recessed pockets on an outer radial surface that coincide with the openings, and sleeve orifices are defined in the inner sleeve at each recessed pocket. A cartridge choke assembly is received within each opening and operatively coupled to the inner sleeve at one of the recessed pocket. The cartridge choke assembly includes a choking module that defines choke orifices alignable with the sleeve orifices. A flow control device is movably disposed within the body between a fully open position, where the one or more sleeve orifices are exposed, and a fully closed position, where the one or more sleeve orifices are occluded.
