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.
Claims8
1-10. (canceled)
A method for preparing and using a polymer-based well tracer, comprising:
- synthesizing at least one fluoropolymer having a fluorinated group,
- wherein the at least one fluoropolymer is synthesized from a polymer and a fluorinated compound;
- introducing the at least one fluoropolymer and a fluid into a formation of a well,
- wherein upon reaction with water and degradation of the at least one fluoropolymer, at least one fluorinated compound is released;
- detecting the at least one fluorinated compound at a surface of the well;
- and
- evaluating at least one property of the well based on detection of the at least one fluorinated compound.
