Description

Early researchers defined the Staunton Dome on the basis of limited well data on Pennsylvanian horizons. Bell (1941) used borehole data and surveys in underground mines to outline an enclosed high covering most of Section 14, T7N, R7W. To the north is a very irregular structural depression. Gas was produced from Pennsylvanian sandstone partially on the high; but little is known about the influence of structural versus stratigraphic factors for trapping gas because of the low-quality logs. The structure map of Nelson (1987b) shows that the Staunton Gas Field is situated on an irregular high having about 20 feet of closure on the Herrin Coal Member. The structure is too poorly defined and the high too subtle and irregular to merit naming.
