Claim 9:
10. A method of fracturing a formation and tracing production fluid via a single downhole multifunctional valve assembly, comprising:
deploying the valve assembly within a wellbore provided in a hydrocarbon- bearing formation, the valve assembly being configured to define:
a fracturing fluid pathway into the formation; and
an enclosed tracer compartment comprising a tracer material sealed therein;
delivering fracturing fluid into the wellbore and through the fracturing fluid pathway to enter and fracture the hydrocarbon-bearing formation;
closing the fracturing fluid pathway after fracturing;
opening the tracer compartment to provide a tracing fluid pathway for production fluid to flow from the hydrocarbon-bearing formation, along the tracer compartment to allow contact with and release of the tracer material, and then into the wellbore to enable flow up to surface.
