Low-side traps may have very different fault seal risk compared with high-side traps. In [[:file:evaluating-top-and-fault-seal_fig10-12.png|Figure 3]], a map shows that dip leakage in the hanging wall limits fill (shaded) to the structurally independent closure. Dip seal in the footwall allows fill in excess of the independent closure. The footwall contains purely fault-dependent traps. The hanging wall relies upon independent closure for entrapment. | Low-side traps may have very different fault seal risk compared with high-side traps.
