Hearn, C L

In fluid-injection projects, such as waterflooding, vertical permeability variation may have a significant effect on sweep efficiency. A method has been developed for calculating pseudo relative permeability curves which reflect the reservoir stratification. These curves can be used in 2-dimensional areal reservoir simulators to approximate the 3-dimensional solution. The pseudo relative permeability curves are based on a mathematical model for calculating the vertical displacement efficiency using a stratified reservoir concept. Equations for calculating the pseudo relative permeability curves, are presented, and theoretical concepts leading to their development from the stratified model are discussed. A field case example illustrates use of the curves in reservoir simulation. It is pointed out that use of relative permeability curves which do not describe vertical effects in the reservoir can lead to incorrect results when used in 2-dimensional areal models.
