Response surface results for the \(\epsilon _\mathrm{{r}}\) using the polynomial method. The blue dots show the detailed model runs using the simulator. The contour lines show the response surface fitted to these detailed model runs and projected into the various subspaces of factor space. The reservoir’s length and the dip angle have the maximum effect on the \(\epsilon _\mathrm{{r}}\). At high dip angles, the permeability has the least effect on the \(\epsilon _\mathrm{{r}}\)
