Abstract
Flow control assemblies comprise a housing that includes a housing body that defines a housing conduit, an injection conduit that extends through the housing body, and a ball sealer seat. The ball sealer seat defines a portion of the injection conduit, is defined on an inner surface of the housing, and is sized to receive a ball sealer to restrict fluid flow from the casing conduit through the injection conduit. The flow control assemblies further include a sliding sleeve that is located within the housing conduit and defines an isolation ball seat. The flow control assemblies also include a retention structure that is configured to retain the sliding sleeve in a first configuration and to selectively permit the sliding sleeve to transition from the first configuration to a second configuration.
