[[:file:evaluating-top-and-fault-seal_fig10-32.png|Figure 1]] illustrates how completely a fault can control [[migration pathways]] across a fault. In this fault plane profile of a fault in a [[Gulf Coast]] field, the shale gouge ratio (SGR) was calculated and contoured only on areas of sand-sand juxtaposition. Areas of sand-shale juxtaposition are uncolored. No hydrocarbon [[migration]] will occur across these uncolored regions or across the sand-shale juxtapositions with low SGRs (blue-purple). These high SGR areas are essentially holes for fluid migration in the fault plane. It will only occur across the areas of sand-sand juxtaposition with high SGRs (red-orange).
