Claim 13:
14. A fracturing and tracer-delivery valve assembly for integration within a wellbore string disposed within a hydrocarbon-containing reservoir, comprising:
a valve housing comprising a wall, a passage extending therethrough, and at least one frac port extending through the wall for establishing fluid communication between the passage and the reservoir;
a flow path sub-assembly disposed within the housing and configured to move between at least (i) a first position defining a first fluid pathway whereby fluid is flowable between the passage and the reservoir via the at least one frac port, and (ii) a tracing position defining a second fluid pathway whereby production fluid is flowable from the reservoir into the valve assembly and then up to surface, the flow path sub-assembly being adapted to move from the first position to the tracing position, and from the tracing position to the first position;
a tracer compartment present within and/or in fluid communication with the second fluid pathway in the tracing position, the tracer compartment accommodating a tracer material.
