According to Demaison and Huizinga<ref name=ch03r4 />), laterally drained petroleum systems have a laterally continuous seal overlying a laterally continuous reservoir. This reservoir/seal couplet is generally contained within a long, uninterrupted ramp. Provinces with these systems have low to moderate structural deformation. Tectonic stability is critical for maintaining seal integrity. Laterally drained systems are most commonly found in fore-deep and cratonic sag basins. Plunging low-amplitude arches are necessary for connecting traps to the pod of active source rock. The Ellesmerian(!) petroleum system is an example of a laterally drained system.

* The largest accumulation is usually found early in the drilling history of the system. After that, mostly small accumulations are found (J. Armentrout, personal communication, 1997).
