* Faults may localize fracturing through the top seal, so evaluate the potential for [[fractured membrane seal leakage]] in the top-seal lithology.

* Faults may localize fracturing through the top seal, so evaluate the potential for [[fractured membrane seal leakage]] in the top-seal lithology.

* Faults must connect to permeable beds higher in the section or to the surface to leak significant amounts of petroleum. If [[growth fault]]s die upsection into a shale interval, leakage may be minimal except where natural [[Natural hydraulic fracturing of top seals|hydrofracture]] ruptures seals.

* Fractures and fault fill may heal by cementation once fault movement stops. Leakage is less likely if trap charge significantly postdates fault movement.

* Fractures and fault fill may heal by cementation once fault movement stops. Leakage is less likely if trap [[Calculating charge volume|charge]] significantly postdates fault movement.

* Conversely, fault movement during or after charge of the trap will always result in some leakage, probably by a form of natural hydraulic fracturing along the fault plane. If charge is sufficient, leakage may be slower than charge, so petroleum may [[Accumulation|accumulate]] and be preserved as long as charging continues.
