Numerical Simulation Study on Fracture Parameter Optimization in Developing Low-Permeability Anisotropic Reservoirs

Figure 3

Plane distribution of remaining oil saturation at different k_x : k_y and fracture parameters combination. (a) Reservoir permeability k_x : k_y = 1 : 1 with no fractured injection well; (b) reservoir permeability k_x : k_y = 3 : 1 with no fractured injection well; (c) injection well has fractures and reservoir permeability k_x : k_y is 1 : 1; (d) injection well have fractures and reservoir permeability k_x : k_y is 3 : 1.
