The Wolfberry play in West Texas combines favorable geology with innovative completion practices to form one of the largest unconventional oil plays in the United States. Wolfberry wells produced almost 55 million barrels of oil in 2011, and that figure could double in a few years.

This report provides a detailed review of the stratigraphic and structural attributes and controls on productivity and future potential of the Cleveland Formation and Marmaton Group by integrating chronostratigraphic, depositional-facies, and play analysis.

This publication helps scientists quickly sort through the entire spectrum of knowledge of salt tectonics, isolate relevant information, and find pathways to more-detailed information.

This six-sheet set of oversize colorful geologic maps and cross sections presents new interpretations on the outcrop pattern and complex structure within the Upper Cretaceous Del Rio, Buda, Boquillas, Pen, Aguja, Javelina, and Cretaceous-Tertiary Black Peaks Formations of Big Bend National Park.

Although the mature, supergiant East Texas field on the west flank of the Sabine Uplift has been producing from the Upper Cretaceous (Cenomanian) siliciclastic Woodbine Group for more than 75 years, no modern comprehensive geologic study of it has been completed.
