Eastern Energy Resources Science Center


The Eastern Energy Resources Science Center (EERSC) addresses national and global energy geoscience issues and conducts interdisciplinary research on energy systems.

What We Provide

The Center provides earth-science information and interpretations essential to building a framework for the identification and assessment of economically stable and environmentally sound resources of petroleum, natural gas, and coal.

What We Address

The Center addresses the economic and environmental effects of energy production and studies unconventional resources including gas hydrates, geothermal resources, uranium, oil shale, and bitumen and heavy oil.

USGS Releases A New Assessment Methodology for Carbon Dioxide Enhanced Oil Recovery and Associated Carbon Dioxide Retention

The U.S. Geological Survey has developed a new assessment method to estimate how much oil and gas could be produced by injecting carbon dioxide into petroleum reservoirs. The methodology also includes a way to estimate the amount of carbon dioxide remaining in the reservoir after the production of oil and gas is complete.

Characterization of the unconventional Tuscaloosa marine shale reservoir in southwestern Mississippi, USA: Insights from optical and SEM petrography

This study presents new optical petrography and electron microscopy data, interpreted in the context of previously published petrophysical, geochemical, and mineralogical data, to further characterize the Tuscaloosa marine shale (TMS) as an unconventional reservoir in southwestern Mississippi. The basal high resistivity zone has a higher...

Origin and geochemistry of formation waters from the lower Eagle Ford Group, Gulf Coast Basin, south central Texas

The lower Eagle Ford Group (LEFG) is one of the most productive continuous hydrocarbon plays in the United States but few associated produced waters data and minimal interpretation have been published. This effort focuses on results from compositional and isotopic data from 39 produced water samples collected from horizontal wells producing from...

Conceptual framework and approach for conducting a geoenvironmental assessment of undiscovered uranium resources

This report presents a novel conceptual framework and approach for conducting a geologically based environmental assessment, or geoenvironmental assessment, of undiscovered uranium resources within an area likely to contain uranium deposits. The framework is based on a source-to-receptor model that prioritizes the most likely contaminant sources,...
