Exploration potential of the Rough Creek Fault System

The Rough Creek Fault System is a complex tectonic element which from its W. end at Hart's Store in Pope County, Illinois, passes generally eastward, entering Kentucky opposite Shawneetown and continuing eastward along a sinuous course north of and roughly parallel to the axis of the Moorman Syncline until losing definition in Hart County. It is similar to and subparallel to a fault system in Marion, Boyle, and Lincoln counties which butts against the Kentucky River Fault System in Lincoln County and may be a westward extension of the Kentucky River Fault System. Geologically, the system consists of normal and reverse faults along which recurrent movement may be proved and which in some places are crowded into a strongly faulted anticline and in other places are spread out into a sytem of fault blocks. The vicinity of the Rough Creek Fault System is relatively untested, except in portions of McLean County, as compared with areas explored to the north and south. However, the abandoned Concord Church pool, occupying only 80 acres in a single fault sliver, accumulated a quarter of a million barrels of oil from the Devonian and is stratigraphically the deepest of any clearly commercial field in W. Kentucky.
