Effects of Different Penetration Patterns on a Fault during Underground Fluid Injection

Figure 6

Pore pressure distribution along the interface between caprock and reservoir from the injection well to the fault (between point and point ) at different times. (a), (b), and (c) present the pore pressure distribution on the interface in Scenario 1, Scenario 2, and Scenario 3, respectively. is the crosscutting point of the fault, and is the crosscutting point of the injection well in all three scenarios. Red dots P1, P2, and P3 locate at 200 m, 400 m, and 600 m, respectively, from the injection well.
