Abstract
A method of tracing flow of hydrocarbon from a subterranean reservoir including forming a dispersion, injecting a hydraulic fracturing fluid containing the dispersion down a well penetrating a hydrocarbon reservoir, thereafter collecting a sample of hydrocarbon fluid flowing from the reservoir, and analyzing the sample to determine whether the tracer compound is present in the sample. The dispersion includes a discontinuous condensed phase having a hydrocarbon-soluble tracer compound and a continuous phase which includes an aqueous liquid.
