Abstract
With the depletion of oil reserves and increase in oil price, enhanced oil recovery methods such as polymer flooding to increaseoil production from waterflooded fields are becoming moreattractive. Effective design of these processes is challengingbecause the polymer chemistry has a strong effect on reaction andfluid rheology, which in turn has a strong effect on fluidtransport. Polymer flow characteristics modeled in the UT-AustinIPARS (Integrated Parallel Accurate Reservoir Simulator) areadsorption on rock surfaces, polymer viscosity as a function of shearrate, polymer and electrolytes concentrations, permeabilityreduction, and inaccessible pore volume. A time-splitting algorithmis used to 'independently' solve advection,diffusion/dispersion, and chemical reactions.
