Claim 8:
9. An apparatus for marking a selected location in a subterranean formation, comprising:
a least one shaped charge configured to generate a perforating jet, wherein detonation of the at least one shaped charge releases thermal energy and shock waves; and
a tracer package including:
at least one fluid production tracer; and
a tracer injector positioned adjacent to the at least one shaped charge, the tracer injector configured to inject the at least one fluid production tracer material into the subterranean formation, wherein the tracer injector includes a gas generating material configured to be initiated by an activation energy released by the detonation of the at least one shaped charge, wherein a high-pressure gas generated by the gas generating material is selected to inject the at least one fluid production tracer material into the subterranean formation.
