The borehole yielded a 500’ rock core containing Austin

One charge of the U.S. Geological Survey’s Energy Resources Science Center is conducting field work to
better understand the distribution of hydrocarbon source rocks as input to USGS oil and gas
assessments. This 2015 image is a view to the south-southeast of rocks exposed along an unnamed

USGS researchers drill a research well located on the south side of U.S. 90, 7.1 miles east of Brackettville, 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 borehole, core, and logging
