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: Functionalized fluorescent tracers, methods of making the tracers, and methods of using the tracers are provided. In some implementations, the fluorescent tracers include a functionalized fluorescent dye. The functionalized fluorescent dye includes an isothiocyanate-containing dye functionalized with a functional group that includes a primary amine. In some implementations, a method of tracing fluid flow in a subterranean formation includes mixing the functionalized fluorescent tracer into a fluid, flowing the tracer fluid into a subterranean formation, recovering a sample from a subterranean formation, and analyzing the sample for a fluorescent signal and a barcode functional group.

Abstract: Methods and systems for generating a nanofluidic chip as a reservoir model are provided. In an example described herein, a nanofluidic chip for reservoir modeling includes a microfluidic chip that includes microchannels etched in a substrate. Silica spheres are assembled in the microchannels to form nanochannels. A carbonate coating is disposed over the surfaces of the nano channels and the silica spheres.

Abstract: A carbonate microfluidic model with controllable nanoscale porosity and methods are described. The method for fabricating a carbonate nanofluidic micromodel with controllable nanoscale porosity for studying fluid behaviors in an underground oil-reservoir environment includes: disposing a plurality of polymer spheres into a transparent flow cell; initiating crystallization of the plurality of polymer spheres to form a template with an opal structure; filling the transparent flow cell with a calcium-based solution and a carbonate-based solution to form nanocrystals in voids of the opal structure; and removing the template formed by crystallization of the plurality of polymer spheres from the transparent flow cell leaving an inverse opal structure with a plurality of nanoscale pores and a carbonate surface. The model includes: a transparent flow cell including a first end defining an inlet and a second end defining an outlet; and an inverse opal structure of carbonate inside the transparent flow cell.

Abstract: A blocking material is injected into a microfluidic chip that includes microscale-porosity microchannels etched in a substrate, filling at least a portion of the microchannels. Silicon dioxide spheres are injected into the microfluidic chip. The blocking material prevents the silicon dioxide spheres from entering the portion of the microchannels filled with the blocking material. The silicon dioxide spheres form a region of nanoscale porosity in a portion of the microchannels not filled with the blocking material. A solvent is injected into the microfluidic chip, the solvent operable to dissolve the blocking material and thereby providing a region of microscale porosity adjacent to the region of nanoscale porosity.

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.
