[[:file:evaluating-top-and-fault-seal_fig10-15.png|Figure 1]] is a simple example of a fault plane profile. The sand reservoirs in the hanging wall (dark gray) and footwall (light gray) are shown on the same cross section drawn in the plane of the fault. In this example, all hydrocarbon [[accumulation]]s (black) are limited by [[Cross-leaking_faults#Juxtaposed_lithology_leak_points|JLLPs (juxtaposed lithology leak points)]]. Hydrocarbons cross-leak from the footwall sands into the hanging wall sands.

The fault cross-leaks along its entire surface at sand/sand juxtapositions. At each sand/sand juxtaposition, a JLLP spills the hydrocarbons across the fault. There is sufficient charge to fill all closures to a fault-dependent leak point. Potential reservoirs with JLLPs at the crest are [[dry. The percent fill for other sands is constrained by the JLLPs.<ref name=ch10r2 /> If bed dips in the hanging wall allow entrapment against the fault, hydrocarbons could be trapped in both the hanging wall and footwall reservoirs. With sufficient charge, common hydrocarbon contacts could exist.
