The [[Mandal-Ekofisk(!) petroleum system]] 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.
