Abstract: One embodiment includes generating a polymer partitioning model that determines a concentration of the polymer in a brine phase of the microemulsion system and a concentration of the polymer in an aqueous component of a microemulsion phase of the microemulsion system. The embodiment includes determining a viscosity of the brine phase of the microemulsion system using the concentration of the polymer in the brine phase of the microemulsion system, determining a viscosity of the aqueous component of the microemulsion phase of the microemulsion system using the concentration of the polymer in the aqueous component of the microemulsion phase of the microemulsion system, and determining a viscosity of the microemulsion phase of the microemulsion system using the viscosity of the aqueous component of the microemulsion phase of the microemulsion system. The embodiment includes using determined viscosities to determine performance of a chemical enhanced oil recovery process scenario.
