Lowstand gravity-flow, sand-prone reservoirs occur in basin-floor and slope systems. They are most often encased within marine hemipelagic mudstones, which serve as seal and sometimes potential [[source rock]]. Traps are often stratigraphic, but postdepositional deformation that places the gravity-flow sand deposit in a structurally high position enhances the potential for focused [[migration]] of hydrocarbon fluids to the reservoir facies.<ref name=ch04r69>Mitchum, R., M., Jr., 1985, Seismic stratigraphic expression of submarine fans: AAPG Memoir 39, p. 117–136.</ref>
