Abstract: The present disclosure describes methods and systems for detecting a multi-modal tracer in a hydrocarbon reservoir. One method includes injecting a multi-modal tracer at a first location in a reservoir, wherein the multi-modal tracer mixes with subsurface fluid in the reservoir; collecting fluid samples at a second location in the reservoir; and analyzing the fluid samples to detect a presence of the multi-modal tracer in the fluid samples.

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: Compositions and methods for determining the origin location of a subterranean sample are provided. Compositions include a nanoparticle tag including a superparamagnetic iron oxide core, an intermediate layer including a fluorescent dye, and a polymer shell. The nanoparticles can be synthesized by functionalizing a superparamagnetic iron oxide nanoparticle core and covalently bonding a fluorescent dye to the functionalized nanoparticle core. In some implementations, a polymer is covalently bonded to the functionalized, fluorescent superparamagnetic iron oxide nanoparticle core. The nanoparticle tag can be used to determine the origin location of a subterranean sample by mixing the nanoparticle tag into a fluid, flowing the fluid into a subterranean formation, recovering subterranean samples from the subterranean formation, and separating tagged samples from untagged samples using a magnet. The origin location of the subterranean sample can be determined by analyzing the fluorescent signal of the nanoparticle tag.

Abstract: Systems and methods of surface logging a well use a plurality of polymeric taggants distinguishable from each other. The systems and methods can include adding each of the plurality of polymeric taggants in a repeating sequence to a circulating drilling fluid while drilling the well and taking a sample drill cuttings carried by the circulating drilling fluid. The systems and methods can also include measuring concentrations of individual polymeric taggants attached to the drill cuttings in the sample and identifying a depth associated with the sample based on the measured concentrations of individual polymeric taggants and on the sequence.
