Fig. 6.12. (Upper) A conceptual cross-section through part of the Statfjord Formation (Triassic) petroleum
reservoir in the northern North Sea showing the complex arrangement of reservoir sands, and nonreservoir
shales. A blanket shallow marine sand at the top of the reservoir presents no problem, but note the problems
of correlating and predicting sand continuity in the lower fluvial part of the section. In such reservoirs a probabilistic approach must be used. (Lower) Stochastic and other statistical methods are employed to produce a
reservoir simulation model to compute the way in which the reservoir will produce petroleum (From Johnson
and Stewart, 1985, by courtesy of the Geological Society of London).
