A study of the deeply buried (>10,000 ft [>3,050 m]) Tertiary section in the Gulf of Mexico, which makes use of whole cores from 12 wells in Louisiana and Texas, provides a framework for interpreting depositional origin and demonstrates that relative position within the sequence-stratigraphic framework and facies tract can exert powerful c

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.
