Abstract
A tracer system is disclosed which is especially useful for following fluid flow in underground reservoirs. Metal chelates, preferably derived from EDTA and containing a functional group which reacts with a fluorogenic agent, are used as tracers. Liquid chromatography and fluorescense spectroscopy are used to detect the metal chelates.
