A recently granted patent (Publication Number: US11885216B2) discloses a method and apparatus for completing a subterranean formation with a borehole and production structure. The method involves conveying a perforator assembly containing shaped charges and tracer packages into the borehole to form tunnels in the production structure. By detonating the shaped charges, the gas generating material is initiated, allowing for the injection of fluid production tracer materials into the formation using high-pressure gas. These tracer materials are designed to physically associate with resident fluids in the subterranean formation, aiding in marking specific locations.

The patent claims detail the use of a propellant material as the gas generating material, with the fluid production tracer material either dispersed within the propellant or physically separate from it. The apparatus described includes shaped charges that release thermal energy and shock waves upon detonation, along with a tracer package containing fluid production tracer materials and a tracer injector. This injector, powered by the gas generating material, injects the tracer materials into the subterranean formation using high-pressure gas, ensuring accurate marking of selected locations within the formation.
