[[:file:migration-of-petroleum_fig7-12.png|Figure 1]] is a hypothetical migration pathway map. The lower map shows the thickness of source rock, the top of the oil and gas windows, and the drainage areas for two traps labeled A and B of the same area shown in the upper map. The drainage areas for traps A and B were made using the migration pathway map.
