Abstract
In this study a new mathematical model was developed that considers thermal effects, dispersion, effective concentration, elastic behavior of viscoelastic polymers, polymer retention, permeability reduction of aqueous phase, salt effects, inaccessible pore volume, and equivalent shear rate in porous media to predict oil recovery of core-flood experiments in process of viscoelastic polymer flooding as a tertiary stage of enhanced oil recovery. The model was found highly reliable when compared to material balance and experimental data. Displacement performance of core-flood tests could be predicted by presented model, therefore, experimental costs will be decreased significantly.
