Rules for Flight Paths and Time of Flight for Flows in Porous Media with Heterogeneous Permeability and Porosity

Figure 15

The pressure distributions for different permeability and viscosity. The corresponding pressure range is given in Table 3. (a) Pressure distribution of the base case model with uniform permeability of 100 mD and the viscosity of water and oil is 0.5 cp and 2 cp, respectively. (b) Permeability is 50 md; other parameters are the same as in the original model. (c) Viscosity for water/oil is 1 cp/4 cp; other parameters are the same as in the original model. (d) Permeability is 25 md; other parameters are the same as in the original model. (e) Viscosity for water/oil is 2 cp/8 cp; other parameters are the same as in the original model.
