Exemplary Micromodel Flooding Experiment

This is the result of an exemplary micromodel flooding experiment summary. The experiments can be performed at reservoir temperature. The micromodels are customized to thin section or CT – images and resemble their respective properties. On request wettability control can be established through surface modification.
