Polymer-based well tracers with tunable release profile
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.
1. A polymer-based well tracer, comprising: a fluoropolymer having a fluorinated tracer covalently bonded with a polymer, wherein upon reaction with water and degradation of the fluoropolymer, the fluorinated tracer comprising a fluorinated compound is released.
2. The polymer-based well tracer of claim 1 , wherein the fluoropolymer is a polyester.
3. The polymer-based well tracer of claim 1 , wherein the fluorinated compound is a fluoro diol.
4. The polymer-based well tracer of claim 1 , wherein the fluoropolymer is synthesized from fluoro carboxylic acids.
5. The polymer-based well tracer of claim 1 , wherein the fluoropolymer is formed into a particle.
6. The polymer-based well tracer of claim 1 , wherein the fluoropolymer is coated onto proppant particulates.
7. The polymer-based well tracer of claim 1 , wherein the fluoropolymer is encapsulated in a polymeric resin.
