Fluid system evaluation with multiple chemical tracers

摘要

Multiple chemical tracers are provided in a fluid system, and measured to evaluate parameters of the system. The multiple chemical tracers include at least one reactive chemical tracer that provides a measurable signal with an intensity that changes as the reactive chemical tracer reacts in the fluid system. The signals of the multiple chemical tracers are compared to each other to evaluate a system parameter, such as temperature, pH, or system events.
