Title: Petrology and Depositional Environment of Mitchell Member, Rodessa Formation (Lower Cretaceous), West Bradley Field, Lafayette County, Arkansas: ABSTRACT

Author(s): Donald Lee Huguley, Jr.


Previous studies of the Lower Cretaceous Rodessa Formation in southern Arkansas have interpreted it as nearshore, transitional marine. Many of the Rodessa members are hydrocarbon productive. Cores from the Sun Whittington wells and Lake Ronel Oil Co. wells in and near the West Bradley field, Lafayette County, Arkansas, were studied to identify a model for deposition of the oil-productive Mitchell sand interval. The Mitchell is sandwiched between the upper and lower Gloyd members of the Rodessa Formation. These two limestone members are productive in other areas of the Arklatex.

A thorough investigation of the sands, using core samples, geophysical log correlation, drilling reports, thin sections, scanning electron microscopy, and x-ray diffraction yields data necessary for establishing the nature of deposition. This information will promote interest and further development of the hydrocarbon potential of the Mitchell member in the Arklatex.
