Description
Bell (1941) mapped the structure of the Herrin Coal Member (Pennsylvanian) in western Clinton County and provided two alternative structural interpretations of the Bartelso Oil Field. In one interpretation, a single dome was mapped. In the other, two separate domes, Bartelso Dome on the south and Beckemeyer on the north, were indicated. Bell's control points were widely spaced and some may have been unreliable. The dome at Bartelso subsequently was found to be a Silurian reef and is discussed under that heading. The Beckemeyer Gas Field contains two wells that produced gas from Chesterian sandstones; tests of Silurian strata have not yielded hydrocarbons or encountered reef facies. The current Beech Creek ("Barlow") Limestone map (ISGS open files) indicates a terrace on a southeast-plunging anticlinal nose in the area of Bell's Beckemeyer Dome (fig. 4). No closure is shown on this map, which has abundant control points and a 20-foot (6.1 m) contour interval. The use of the name Beckemeyer Dome, therefore, should be discontinued.
