Abstract: Compositions and methods for extracting tracers from subterranean fluids are provided. The compositions include a media for solid phase extraction. The media includes a homogenous mixture of a first and second sorbent. The first sorbent includes a crosslinked polystyrene divinyl benzene copolymer core functionalized with hydroxylated polystyrene divinyl benzene copolymer. The second sorbent includes a crosslinked polystyrene divinyl benzene core functionalized with a copolymer that includes secondary and tertiary amino groups. A solid phase extraction cartridge including a homogenous mixture of the first and second sorbent is also provided. Methods of extracting tracers from subterranean fluids include extracting the tracers with a solid phase extraction column that includes a homogenous mixture of the first and second sorbent.

Abstract: Compositions and methods for determining the origin location of a subterranean sample are provided. Compositions include a polymer-clay composite tag. The tag includes a nanoclay including a plurality of layers, and a polymer intercalated between the layers of the nanoclay. The polymer is functionalized with a fluorescent dye. A method to determine the origin location of a subterranean sample includes mixing a barcoded polymer-clay composite tag into a fluid, flowing the fluid through a work string into a subterranean formation, recovering subterranean samples from the subterranean formation, and determining the origin location of the subterranean sample by detecting the presence of the barcoded polymer-clay composite tag.

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 method includes introducing into a drilling fluid a plurality of tags having a first clay nanoparticle and a first polymer embedded into the clay nanoparticle and circulating the drilling fluid and tags through a well during a drilling operation that creates formation cuttings such that the tags interact with the formation cuttings, creating tagged cuttings. The returned cuttings are collected from the circulating drilling fluid at a surface of the well, and the tags on the returned cuttings are detected to identify the tagged cuttings. The method also includes correlating the tagged cuttings with a drill depth in the well from the drilling operation.

Abstract: Devices for chemical analysis include a first separation element formed on the substrate, the first separation element having a wicking surface that separates water from hydrocarbons in a fluid sample, a hydrophobic barrier at least partially surrounding the first separation element, a second separation element fluidically connected the first separation element, the second separation element configured to trap salts and organic matter present in the fluid sample, and a detection element fluidically connected to the second separation element, the detection element having a surface that binds with one or more analytes that may be present in the fluid sample and thereby emits a signal that is capable of being optically detected by a detector. Methods include providing such a device for chemical analysis, placing the fluid sample on the first separation element, and detecting the signal emitted by the detection element.

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.
