Title: South-North Cross Section from Pecos County Through Ector County, Texas, to Roosevelt County, New Mexico

Author(s): W. C. Fritz (2), James Fitzgerald, Jr. (2)


The section from Shell-Kirby University No. 1 in central Pecos County, Texas, to Franklin Gephart No. 1 in northern Roosevelt County, New Mexico, extends generally along the eastern part of the Central Basin platform. It traverses most of the Upper Castile basin of deposition and shows its northern limit. Through Crane, Ector, and Andrews counties, the cross section is along the strike of the beds of the Whitehorse group. It shows the progressively increasing depth of the porous and producing zones from the Whitehorse group into the San Andres group, although the only oil wells shown on the section are producing from the San Andres or older beds. Some idea of the magnitude of the unconformity at the base of the Permian is indicated in the first ten wells in the section. T e suspected relationship of the Glorieta (base of San Andres group) with the undifferentiated Permian of the southern part of the Central Basin platform is also shown.
