    Abstract: A method of quantifying zonal flow in a multi-lateral well is described. A first taggant is flowed to a first lateral, and a second taggant is flowed to a second lateral. A first produced fluid that includes the first taggant is flowed from the first lateral into a production tubing. A second produced fluid that includes the second taggant is flowed from the second lateral into the production tubing. A produced stream including the first produced fluid and the second produced fluid is flowed uphole through the production tubing. An amount of the first taggant and an amount of the second taggant in the produced stream are measured. Production of fluid from the multi-lateral well proceeds without ceasing throughout the method.

    Abstract: A method of treating a subsurface formation with a coated proppant includes introducing the first hydraulic fracturing composition into a wellbore and the subsurface formation through a first zone of the plurality of zones of the subsurface formation; propagating at least one subsurface fracture in the first zone with the first hydraulic fracturing composition, and wherein the hydraulic fracturing composition includes a fluid medium and a first coated proppant dispersed within the fluid medium, the first coated proppant including: a particulate substrate; a first polymeric layer surrounding the particulate substrate, the first polymeric layer including a first chemical additive; and a second polymeric layer surrounding the first polymeric layer, the second polymeric layer including a first chemical tracer, the first chemical tracer including barcoded degradable polymers, fluorescent dyes, quantum dot nanoparticles, paramagnetic nanoparticles, up-conversion phosphors, long-persistent phosphors, or time-resolved fluorescence resonance energy transfer polymer-nanoparticles (TR-FRET).

    Abstract: A method, system, and taggants (tracers) for quantifying zonal flow in a multi-lateral well having a wellbore with a first lateral and second lateral. The technique includes flowing first produced fluid from a formation via the first lateral into production tubing providing a first taggant through a first dosing tubing to the first lateral, and flowing second produced fluid from the formation via the second lateral into the production tubing and providing a second taggant through a second dosing tubing to the second lateral. A produced stream having the first produced fluid and the second produced fluid flows uphole through the production tubing and discharges from the wellbore. The produced stream may be analyzed to measure an amount of the first taggant in the produced stream and an amount of the second taggant in the produced stream.

    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.
