    摘要: 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.

    摘要: A valve assembly for integration within a wellbore string disposed within a hydrocarbon-containing reservoir is provided. The valve assembly includes a valve housing having a plurality of frac ports for establishing fluid communication between a central passage and the reservoir. The valve assembly includes a bottom sleeve operatively mounted within the valve housing configured to selectively open the frac ports, and a top sleeve operatively mounted within the valve housing slidable between (i) a first position defining a first fluid pathway whereby fluid is flowable down into the central passage and into the reservoir via the frac ports, and (ii) a tracing position defining a second fluid pathway whereby fluid is flowable from the reservoir into an annulus defined between the top sleeve and the housing. The valve assembly also has a tracer compartment defined within the annulus forming part of the second fluid pathway and accommodating a tracer material.
