Abstract
Described is a polymer-based well tracer. The polymer-based well tracer is a fluoropolymer having a fluorinated group. The fluoropolymer may be formed into a particle, a coating for proppant particulates, or encapsulated in a polymeric resin. Upon degradation or hydrolysis of the fluoropolymer, the fluorinated group having a fluorinated compound is released within the well.
