Abstract
A method is described for selecting an additive for enhanced recovery from a subterranean hydrocarbon reservoir including the steps of using a set of parameters to determine, at a first level of molecular dynamic modeling, an effect of the additive on interfacial tension between a hydrocarbon and water/brine; using the effect of the additive on interfacial tension derived from the first level of molecular dynamic modeling to determine, at a second coarser level of molecular dynamic modeling wettability effects; and using the effect of the additive on interfacial tension derived from the first level of molecular dynamic modeling and the wettability effects derived from the second level of molecular dynamic modeling to determine at a third coarser level of molecular dynamic modeling imbibition or drainage effects.
