Summary Understanding physico-chemical interactions and quantification of reaction kinetics during dynamic processes in multi-phase systems and their impact on the electric conductivity can help to interpretation EM-monitoring data. Therefor a multistage experimental setup was developed and performed on different reactive and non-reactive rock-fluid-gas systems.
The results shows that the real part of the el. conductivity decreases by about -90% in the dewatered states and after imbibition the el. conductivity increases differently depending on material and measuring height. A combination of reactive materials show the strongest conductivity changes after cycles of dynamic processes.
