Description

The Parkersburg Dome was defined on the basis of subsurface contouring on the Beech Creek ("Barlow") Limestone and the Levias Limestone Member of the Renault Formation (Chesterian). Easton (1943) showed that the dome trends slightly east of north and is about 5 miles (8 km) long by 2 miles (3 km) wide. The current Beech Creek structure map (lSGS open files), based on numerous control points not available to Easton, indicates no closure in this area. Parkersburg Dome and the adjacent Blackoak Dome, as mapped by Easton, actually are parts of an irregular terrace that lies along the east flank of a broad syncline east of the Clay City Anticline. The Parkersburg Consolidated Oil Field has been developed along this terrace. Its cumulative production, mainly from stratigraphic traps in the Cypress and Bethel Sandstones and Ste. Genevieve and Salem Limestones, is more than 12.8 million barrels. Use of the name Parkersburg Dome should be discontinued.
