  Waterflood displacement efficiency is affected by the viscosity ratio of the displaced to the displacing fluid. Therefore, the oil recovered in a water flooding process is largely determined by the viscosity ratio. This paper presents a quantitative analysis of the viscosity effects on oil recovery in a linear system using Buckley-Leverett equation and other related mathematical models to simulate the effects on two stages: Case one, when the viscosity of the displaced fluid was varied from 5cp to 300cp and that of the displacing fluid remained constant at 1cp. And case two, when the viscosity of the displaced fluid was at 2cp and that of the displacing fluid varied from 2cp to 10cp with the assumption of miscibility between the viscous water and the interstitial water or previously injected water. With the aid of the fractional flow curves, the value for .. View More»
