The numerical result comparison between 4 m and 15 m formation thickness with a 60-degree approaching angle: (a) the injection pressure history at the injection location; (b) damage factor (SDEG) contours with a 4 m formation thickness (deformation scale factor is 100); and (c) SDEG contours with a 15 m formation thickness.
