... Abstract The ratio between the viscous and capillary forces, commonly denoted the Capillary Number Nc, is crucial in determining the remaining oil saturation. The impact on residual oil saturation by a systematic increase in Nc is determined in homogeneous chalk at wettabilities varying from...

... as angular capillaries of variable polygon shapes provides a valid physical basis for corner flow. The fluid distribution above the gas/oil contact is influenced by in-situ capillary force but more by the fluid dynamics. Numerical simulation of the film/corner flow was conducted for various cross sectional...
