Description
The Centralia Anticline, where the Centralia Oil Field is developed, lies on the upthrown west side of the Du Quoin Monocline. The anticlinal axis curves from a north-south to a northwest trend. As mapped by Brownfield (1954) on the Beech Creek ("Barlow") Limestone, the Centralia Anticline has more than 100 feet (30 m) of closure (fig. 31). It is about 8 miles (13 km) long and up to 3.5 miles (5.5 km) wide.
Using a series of isopach and structure maps, Brownfield showed that arching of the Centralia Anticline began during Silurian or Devonian time and continued through and after the Pennsylvanian Period. The largest movements apparently took place late in the Mississippian Period and early in the Pennsylvanian Period.
The Centralia Oil Field was discovered in 1937. By 1992, it had produced more than 58 million barrels of oil from pay zones in Pennsylvanian, Mississippian, Devonian, and Ordovician strata.
