Relationships between crude oil viscosity, residual oil concentration, WOR, porosity and permeability are described graphically. Residual oil increases as the viscosity of the reservoir crude increases. Use of a polymer flood containing partially hydrolyzed polyacrylamide in Bartlesville sand cores improved coverage (oil recovery) by 24 percent. For a specific polymer flood viscosity, the amount of polymer required decreases as its molecular weight increases. The flood viscosity can be increased by decreasing TDS below 50,000 mg/l and also by decreasing the permeability variation of the reservoir. The recovery efficiency increases as the flood viscosity increases.
