DOWNHOLE FLOW CONTROLLER

Abstract: a flow control apparatus for producing hydrocarbon material from a subterranean formation is disclosed. the apparatus includes a housing that defines a housing passage, and a flow communicator that extends through the housing for effecting fluid communication between the housing passage and the subterranean formation. the apparatus includes a flow controller within the housing for modulating flow communication between the housing passage and the subterranean formation via the flow communicator. the flow controller includes a filter medium-defining counterpart and a shroud-defining counterpart, and the filter medium-defining counterpart has a filter medium. the flow controller is configurable for disposition relative to the flow communicator to open, close, or screen the flow communicator. while the filter medium and the flow communicator are not aligned, the housing and shroud-defining counterpart shields the filter medium from the housing passage and the external environment.
