Petrographic and petrophysical characterization of the Eagle Ford Shale in La Salle and Gonzales counties, Gulf Coast Region, Texas
The Eagle Ford Shale is an organic-rich marine carbonate-dominated mudrock located in the Gulf Coast Region, Texas. This mudrock was deposited during the Late Cretaceous and is composed of two main members: the lower and the upper Eagle Ford, which are associated to marine transgression and regression episodes respectively. Petrographic analysis of two cores from wells located in Gonzales (Well #1) and La Salle (Well #2) counties indicates that the Eagle Ford Shale has a strong cyclic character. Eight different facies and six microfacies were recognized at different well depths. A paleontologic ...
