Abstract
A method for completing a subterranean formation includes conveying a perforator assembly into a borehole drilled in the subterranean formation. The perforator assembly includes at least one shaped charge and at least one tracer package that includes at least one fluid production tracer material and a tracer injector. The method further includes forming at least one tunnel in a production structure by detonating one or more shaped charges and injecting the at least one fluid production tracer material into the formation using the tracer injector after the detonation of the at least one shaped charge. The at least one production tracer material physically associates with at least one resident fluid in the subterranean formation.
