Moonrise over Night Drilling for the Eagle Ford
USGS scientists drilling a research core near Waco, Texas. This core was drilled by USGS during field work for an oil and gas assessment for the Eagle Ford of the Gulf Coast Basins. Cores like these provide information on the various rock layers, such as their make-up, their age, etc.
The USGS assesses undiscovered, technically recoverable oil and gas resources for the onshore United States and state territorial waters. Learn more about our Gulf Coast energy research: https://energy.usgs.gov/RegionalStudies/GulfCoast.aspx
