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

Figure 6

Three-dimensional color map surface of oil recovery percent of reserves when the water injection well has fracture. (a) Reservoir permeability k_x : k_y is 1 : 1; (b) reservoir permeability k_x : k_y is 3 : 1; (c) reservoir permeability k_x : k_y is 6 : 1; (d) reservoir permeability k_x : k_y is 10 : 1.
