Bedding features in the core from the USGS Gulf Coast #4 Bonham borehole, in the Eagle Ford Group mudstones from a depth of about 401 feet, Fannin County, Texas. The Eagle Ford Group lies underneath the Austin Chalk and serves as the source rock for much of the Austin Chalk's petroleum.

Did you know there are more than 57,000 wind turbines in the United States? In this video, we'll show you how you can get to know each and every one of them with our U.S. Wind Turbine Database and viewer, which we've assembled in partnership with the U.S. Department of Energy, DOE’s Lawrence Berkeley National Laboratory and the American Wind Energy Association.

USGS scientists drill a research well near Waco, Texas, as part of the assessment of oil and gas resources in the Eagle Ford Group.  Cores like these provide information on the various rock layers, such as their make-up, their age, etc.
