Abstract
Flow control assemblies for downhole operations and systems and methods including the same are disclosed herein. The systems include a flow control assembly that is configured to control a fluid flow between a casing conduit and a subterranean formation. The flow control assembly includes a housing that includes a housing body that defines at least a portion of the casing conduit. The housing also includes an injection conduit, which extends between the casing conduit and the subterranean formation, and a ball sealer seat, which defines a portion of the injection conduit. The flow control assembly further includes a hydraulically actuated sliding sleeve that controls a fluid flow through the injection conduit. The methods include pressurizing a portion of the casing conduit, transitioning the hydraulically actuated sliding sleeve from a closed configuration to an open configuration, stimulating the subterranean formation, and receiving a ball sealer on the ball sealer seat.
