Abstract: Analyzing a fluid extracted from a reservoir includes introducing a first composition featuring a first complexing agent into a reservoir at a first location, extracting a fluid from the reservoir at a second location different from the first location, combining the fluid with a second composition featuring a concentration of a lanthanide ion to form a third composition featuring a concentration of a complex formed by the first complexing agent and the lanthanide ion, exposing a quantity of the complex to electromagnetic radiation for a first time period ending at a time t0, detecting fluorescence emission from the quantity of the complex for a second time period starting at a time t1>t0, where t1-t0 is greater than 2 microseconds, and determining information about a fluid flow path between the first location and the second location.

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: 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 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.
