Abstract: Systems and methods for analyzing groundwater samples with multiple organic tracer species from a petroleum containing reservoir include obtaining the sample, isolating an aqueous fraction of the groundwater sample, separating the aqueous fraction into a plurality of components, where each component corresponds to a different one of the organic tracer species, combining each of the separated components with at least one lanthanide element to form a plurality of component solutions, where a ratio of the at least one lanthanide element to the separated component in each component solution is 5:1 or greater, and analyzing each component solution to determine a relative amount of each organic tracer species in the groundwater sample.

Abstract: The present disclosure describes methods and systems for detecting a tracer in a hydrocarbon reservoir. One method includes injecting a tracer at a first location in a reservoir, wherein the tracer mixes with subsurface fluid in the reservoir; collecting fluid samples at a second location in the reservoir; mixing a magnetic surface-enhanced Raman scattering (SERS) particle with the fluid samples; applying a magnetic field to the mixed fluid samples; and analyzing the fluid samples to detect a presence of the tracer in the fluid samples.

Abstract: Spherical grains and sacrificial particles are mixed in a suspension. The sacrificial particles are larger than the spherical grains. The suspension is injected into a channel in a microfluidic chip, and the spherical grains form microporous structures in the channel. The microporous structures are sintered in the channel. A solvent is injected into the channel, and the solvent dissolves the sacrificial particles and forms macropores between at least some of the microporous structures, thereby forming a mixed-porosity microfluidic chip.
