Fine-grid intermediate scale simulations were conducted with the effective-fingering model for domains with different degrees of heterogeneity. Coarse-grid simulations were run to determine the shape factor (one of the effective-fingering model...

... as it moves away for the wellbore (the inlet point). This size change can be clearly seen for the case at injection rate of 6 bpm, where the blue area is large close to the wellbore and smaller in the stages that have moved further away from wellbore. In the next simulations, the viscosity ratio of the two...

... coreflood experiments in which the displacement front could be unstable, for instance due to adverse viscosity ratio. The method proposed here modifies the JBN technique, and hence is referred to as modified JBN (MJBN), by including a viscous fingering term (η) in the oil fractional flow. In order...

... Darcy-type modeling of fluid flux is not predictive under unstable conditions (very small displacing to displaced phase viscosity ratios) at small displacement rates. A fractal analysis is convenient and appropriate. Using statistical theories and concepts of fractal geometry, we derive scaling power...
