Demaison and Huizinga:<ref name=ch03r4>Demaison, G., Huizinga, B., J., 1994, Genetic classification of petroleum systems using three factors: charge, migration, and entrapment, in Magoon, L., B., Dow, W., G., eds., The Petroleum System—From Source to Trap: AAPG Memoir 60, p. 73–89.</ref> divide petroleum systems into vertically and laterally drained. An earlier section of this chapter describes the Mandal-Ekofisk(!) petroleum system, which is a vertically drained system. Vertically drained systems are generally found in rifts, deltas, wrenches, and overthrust provinces where migration is controlled by faults and fractures. Faults and fractures limit the size of the fetch area available to traps, so a number of small- and medium-sized accumulations abound.
