Abstract
A proppant composition comprises a non-radioactive, detectable tracer at least partially embedded in a ceramic composition. The composition may be prepared by agglomerating granules of the ceramic material and granules of the non-radioactive, detectable material to produce the particle by compression. Backflow of proppants in a fractured subterranean formation into which a plurality of particles of the proppant composition have been introduced may be tracked by analyzing a sample of the backflow by detecting for presence of the tracer in the sample.
