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).
