This paper describes a material balance method for deriving interblock water-oil pseudo-functions for application in coarsely gridded areal reservoir models. The method is shown to be effective in pattern waterflood simulation. This technique differs from previous methods in (a) explicitly accounting for grid orientation by deriving directionally dependent pseudos, (b) combining a dispersion control scheme with the pseudo derivation, and (c) matching fractional flow in pattern models through a material balance. The pseudo-functions are derived from fine grid pattern models and account for various effects, including: (1) anisotropic formation properties, (2) dominant displacement forces (viscous or gravitational), and (3) grid orientation (correcting for preferential directional flow).
