The kinetic interface-sensitive (KIS) tracer experiment is a newly developed method to
quantify the fluid-fluid interfacial area (FIFA) during drainage processes. The concentration
breakthrough curves, obtained by measuring reaction product concentration in brine/water
samples after breakthrough, are interpreted with a specialized numerical model to determine
the FIFA. However, this method has its own limitations since the volume of the usable water
sample (after breakthrough), based on which the analysis takes place, is often insufficient …

The kinetic interface-sensitive (KIS) tracer test is a newly developed tracer approach to
measure the fluid-fluid interfacial area (IFA) during dynamic two-phase flow in porous media.
This new tracer approach can be applied for multiple geological applications, where
dynamic two-phase flow is involved, eg monitoring the plume during geological storage of
carbon dioxide. The obtained concentration breakthrough curves by measuring reacted
tracer concentration in water samples are interpreted with a specialized Darcy-scale …
