Gulf Coast Geologic Energy Assessments

View Assessments

The Gulf Coast Geologic Energy Assessments and Research (GEAR) project assesses and characterizes undiscovered, technically recoverable domestic petroleum resources. It focuses on the onshore and State waters portion of the Gulf Coast basin. The primary goal of this project is to meet the needs of Congress and other stakeholders for timely and robust assessments of petroleum resources in the Gulf Coast region. The Gulf Coast GEAR project also conducts associated research on the processes that impact the formation, accumulation, occurrence, and alteration of hydrocarbon energy resources.

Correlation of the Eagle Ford Group, Woodbine Group, and equivalent Cenomanian-Turonian Mudstones using regional wireline-log cross sections across the Texas Gulf Coast, U.S.A.

As part of the U.S. Geological Survey’s 2018 hydrocarbon assessment of the Eagle Ford Group and associated Cenomanian-Turonian strata, a series of regional wireline-log cross sections were constructed to examine geologic characteristics of this stratigraphic interval across the Texas Gulf Coast from Mexico to Louisiana. The cross sections were used to help define six continuous...

Estimating thermal maturity in the Eagle Ford Shale petroleum system using gas gravity data Estimating thermal maturity in the Eagle Ford Shale petroleum system using gas gravity data

Basin-wide datasets that provide information on the geochemical properties of petroleum systems, such as source rock quality, product composition, and thermal maturity, are often difficult to come by or assemble from publicly available data. When published studies are available and include these kinds of properties, they generally have few sampling locations and limited numbers and types...

Geochemical and mineralogical characterization of the Eagle Ford Shale: Results from the USGS Gulf Coast #1 West Woodway core Geochemical and mineralogical characterization of the Eagle Ford Shale: Results from the USGS Gulf Coast #1 West Woodway core

The Eagle Ford shale is a major continuous oil and gas resource play in southcentral Texas and a source for other oil accumulations in the East Texas Basin. As part of the U.S. Geological Survey’s (USGS) petroleum system assessment and research efforts, a coring program to obtain several immature, shallow cores from near the outcrop belt in central Texas has been undertaken. The first of...
