Abstract:
Tracing subterranean fluid flow includes providing a first polymeric tracer to a first injector, collecting a first aqueous sample from a first producer, and assessing the presence of the first polymeric tracer in the first aqueous sample. The first polymeric tracer includes a first polymer formed from at least a first monomer. The presence of the first polymeric tracer in the first aqueous sample is assessed by removing water from the first aqueous sample to yield a first dehydrated sample. pyrolyzing the first dehydrated sample to yield a first gaseous sample, and assessing the presence of a pyrolization product of the first polymer in the first gaseous sample. The presence of the pyrolization product of the first polymer in the first gaseous sample is indicative of the presence of a first subterranean flow pathway between the first injector location and the first producer location.

Claim (Index 2):
The method of  claim 1 , wherein providing the polymeric tracer comprises providing the polymer tracer to the injector location to flow through the subterranean formation from the injector location to the producer location, and wherein the polymeric layer comprises polyethyleneimine (PEI) or a crosslinked carbohydrate-based coating.
