A new generation of tracers for the characterization of interfacial areas during supercritical carbon dioxide injections into deep saline aquifers: Kinetic interface-sensitive tracers (KIS tracer)

► Development of kinetic interface-sensitive tracers for characterization of CO2/brine interfaces. ► Methodology for a molecular target design of suitable tracer substances. ► Synthesis of envisaged tracer compounds and exploitation of interface reaction kinetics. ► Lab experiments and consecutive modeling confirm interface-sensitivity.
