The concept is that the viscosity of injected supramolecular system will be maintained at initially low values for easy injection and pumping, and then increased by means of an external pH stimulus just before or upon contacting oil. Our promising lab-scale preliminary studies have indicated that such supramolecular systems possess not only reversible pH-responsive properties but also very tolerant against high salinities and temperatures. Supramolecular solutions can adapt to the confining environment. For instance, when a height molecular weight polymer macromolecules are forced to flow into narrow channels and pores, molecular scission processes may take place. Supramolecular solutions can have significant impact on the cases where thermal methods cannot be used for some viscous oils due to thin zones, permafrost conditions and environmental constraints. This project is primarily aimed at developing novel supramolecular assemblies with adjustable viscosity and interfacial properties that have robust tolerance against high temperatures and salinities. Such supramolecular assemblies will be used to significantly improve the feasibility and cost-effectiveness of displacement fluids used in EOR. Overall, there is a significant potential for application of supramolecular solutions in the US and throughout the world.
