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.

摘要： A wellbore apparatus to control the flow of fluids into the wellbore, comprising: a housing; a passage disposed within the housing; a flow communicator for allowing communication into the passage; a flow control member; and frangible members releasably retaining the flow control member to the housing in a retained position, and configured, while the apparatus is disposed in an operative orientation, for becoming fractured in response to application of a force in a downhole direction to release the flow control member from the housing such that the flow control member becomes displaceable relative to the flow communicator; wherein: the flow communicator and the flow control member are configured such that, while the apparatus is disposed in the operative orientation within the wellbore, the flow control member is disposed uphole relative to the retained position while the flow communicator is disposed in the open condition.
