1. A method for completing a subterranean formation having a borehole and a production structure, comprising:
conveying a perforator assembly into a borehole drilled in the subterranean formation, wherein the perforator assembly includes at least one shaped charge and at least one tracer package, wherein the tracer package includes at least one fluid production tracer material and a tracer injector, wherein the tracer injector includes a gas generating material;
forming at least one tunnel in the production structure by detonating one or more shaped charges;
initiating the gas generating material using an activation energy released by the detonation of the shaped charges; and
injecting the at least one fluid production tracer material into the formation using a high-pressure gas generated by the gas generating material, wherein the at least one production tracer material is configured to physically associate with at least one resident fluid in the subterranean formation.
