The Sewell-Eddleman area in Young County, Texas, was discovered in January, 1937. Fifty-nine oil or gas wells have been completed to date and six producing zones have been encountered at depths ranging from 2,300 to 4,500 feet, all in rocks of lower Pennsylvanian age except the lowest zone which is Mississippian in age. The limits of the producing area are not yet defined.
The structure of the area is described as an east-west trending anticline, approximately 6 miles long and 2 miles wide, cutting across the axis of the Bend arch. Evidence now available indicates that folding increases with depth. Subsurface structure maps on two horizons, four cross sections through wells, and supporting, tabulated well data present the principal structural and stratigraphic facts about the area.
