The 4 townships making up the SE. quarter of Marion County, Illinois, contain 7 relatively small oil pools. The major portion of the oil produced from these pools was trapped in oolitic limestones and sandstones of the Ste. Genevieve Formation. The oil appears to be accumulated in stratigraphic traps, as no significant structural closure is evident. A reconstruction of the geologic history of the area, aided by the technique of trend-surface fitting, suggests that structural folding was, however, an important factor in trapping the oil. Subsequent tilting of the area has removed the closure of the structures, but the oil did not escape because of permeability pinch outs of the reservoir beds.
