Original Abstract Submitted
described is a system for identifying a leak in a casing-casing annulus of a well. the system includes a chemical tracer spool positioned at a casing-casing annulus of a wellbore. the chemical tracer spool includes a porous layer with a polymer media and a chemical tracer molecule embedded in the porous layer. an inner surface of the porous layer defines a flow channel configured to allow fluid flow of a fluid. the chemical tracer molecule has a chemical affinity for oil, gas, or water, and is configured to diffuse into the fluid flow. a collection point is configured to collect a sample of the fluid.
