Viscoelastic fluids are efficiently utilized in flooding subterranean reservoirs by first flooding a porous medium representative of the reservoir rock with the formation fluids at the desired velocity of the oil recovery process, then flooding a similar porous medium with the viscoelastic fluid at the same velocity and observing the viscosity thereof and thereafter designing the oil recovery process based on this viscosity. It has been observed that the viscosity of viscoelastic fluids is dependent on the velocity. Examples of useful viscoelastic fluids include micellar solutions, aqueous solutions of polyacrylamides, etc.
