Monitoring and detecting seal integrity with tracers

Abstract

Methods and systems are provided for monitoring a tracer within a monitored system that includes at least three barrier layers and at least three corresponding tracers. The barrier layers—referred to as a first, second, and third barrier layer—may each have an initial association with a different one of the three tracers. The methods and systems may further enable detection, such as after the monitoring step, of a tracer at a location outside its initial associated barrier layer, where the detected tracer may be one of the three tracers. In certain embodiments, additional barrier layers and/or additional tracers may be employed, and interactions between and/or among them may allow determination of the location, concentration, amount, and identity of one or more traced compositions, including, for example, identification of breaches, within sealable monitored systems.
