Abstract: Compositions and methods for determining the origin location of a subterranean rock sample. Compositions include a nanoparticle tag with a fluorescent core and a polymer shell. The fluorescent core can include up-converting nanoparticles, rare earth element doped oxide, long persistent fluorescent materials, or encapsulated lanthanide complexes. Methods include mixing a nanoparticle tag into a fluid, flowing the fluid through a work string into a subterranean formation, recovering subterranean rock samples from the subterranean formation, and determining an origin location of the subterranean rock sample by detecting the presence of the nanoparticle tag on the sample.

Abstract: A technique of utilizing waste as an interwell tracer. The waste includes pharmaceutical, personal care product (PPCP) waste or nanoplastic (NP) waste, or both. The system and method includes injecting an injection fluid including water and the waste at an injection well into a subterranean formation, producing produced fluid including water at a production well from the subterranean formation, measuring concentration of the waste in the produced fluid, and comparing the concentration of the waste in the produced fluid with the concentration of the waste in the injection fluid.
