The waterflood performance of a water-wet, stratified system with cross flow is computed by a finite difference procedure. The effects of 5 dimensionless parameters on the oil displacement efficiency, water-saturation contours, and cross-flow rates are evaluated in the absence of gravity forces. The crossflow due to viscous and capillary forces is shown to exert a significant effect on oil recovery in a field-scale model of a 2-layered, water-wet sandstone. The cross flow is at a maximum in the vicinity of the front advancing in the more permeable layer. Under favorable mobility ratio conditions, the computed oil recovery, with cross flow, always is intermediate between that predicted for a uniform reservoir and that for a layered reservoir with no cross flow.
