Map view of the 3D reservoir model of the heterogeneous Delft Sandstone. The injection well is indicated in blue and the production well indicated red, well spacing is 990 m. Each cell is 30 m by 30 m by 2.5 m (x, y, z). The vertical fault is indicated by the purple line (shown here with a permeability of 0.75 mD), has a width of 30 m and extends throughout the domain along the x-axis. The different fault permeability values used in the analysis are listed in Table 3
