Abstract: Lower Cretaceous Carbonate Rocks of Central South Texas

J. W. Wooten, W. E. Dunaway

Recent research on the Albian and Lower Cenomanian Edwards shelf margin along the Gulf of Mexico has disclosed a narrow band of biogenic growth consisting of reefs, banks, bars, and islands. In light of evidence obtained from Sligo tests within the study area, the shelf-margin theory derived from this research is assumed to apply to the Aptian Sligo shelf-margin as well.

Utilizing good-quality modern CDP seismic data in areas of adequate well control, we can relate the major facies and structural components of the model to certain geophysical criteria common to several hundred miles of seismic dip control. Selected seismic sections demonstrate that these criteria are valid in defining the shelf, shelf margin, and shelf slope of each formation, as well as their relation to one another. Through the correlation of these geophysical criteria with existing well control, detailed structural configuration and facies distribution have been obtained, as well as a prime fairway for hydrocarbon accumulation for both the Edwards and Sligo.
