Abstract

Immiscible fluid displacement through a porous medium has many critical applications, such as oil recovery from reservoirs by water injection. These processes are controlled by many important factors such as oil and water relative permeability and fluid viscosity. This research's primary objective is to study the performance of displacing fluid (water) to displace oil depending on the water to oil viscosity and relative permeability. Analytical works based on fractional flow equations have been used with different viscosity ratios and mobility ratios, as the displacing fluid's viscosity is necessary for oil recovering operations. The following data are required in this study, and they are obtained from one Iraqi oil field from a limestone reservoir. The relative permeability ratio for water-oil flow is water saturation in the porous medium used and the water-oil viscosity ratio. In this study, fractional flow equations are derived, and water cut is calculated and plotted versus water saturation for different cases of viscosity ratio μo/μw. Other parameters such as mobility ratio, average water saturation at breakthrough, and endpoint of relative permeability are calculated for accomplishing the study.
