This site highlights the assessments of the Gulf Coast Petroleum Systems Project. Scientifically robust assessments of undiscovered, technically recoverable hydrocarbon resources are published in a variety of USGS publications. This project also conducts research on the processes that impact the formation, accumulation, occurrence and alteration of hydrocarbon energy resources. The Gulf Coast Petroleum Systems Project focuses on the onshore and State waters portion of the Gulf Coast basin.
The Gulf Coast Petroleum Systems Project is part of the USGS Energy Resources Program, with staff in Reston, Virginia at the Eastern Energy Energy Resources Science Center and Denver, Colorado at the Central Energy Resources Science Center. Our mission is to conduct scientifically robust assessments of undiscovered, technically recoverable hydrocarbon resources and to conduct research on the processes that impact the formation, accumulation, occurrence and alteration of hydrocarbon energy resources. The Gulf Coast Petroleum Systems Project focuses on the onshore and State waters portion of the Gulf Coast basin. The offshore Gulf of Mexico Basin outboard of the State-Federal boundary (map) is within the purview of the Bureau of Ocean Energy Management (BOEM).
The project conducts geologic-based quantitative assessments of undiscovered, technically recoverable oil and gas resources across the Gulf Coast basin, and we conduct research on petroleum systems elements that provides the underlying data and interpretations for each assessment. Different methodologies are used for assessments of conventional and continuous oil and gas accumulations. Conventional oil and gas accumulations develop through migration of generated hydrocarbons into a porous and permeable rock unit, while continuous accumulations are regional accumulations of oil and/or gas that is dispersed throughout the matrix of the host rock unit (see Schmoker (2005) and Schmoker and Klett (2005) for more information).
Listed below are the publications related to the most recent assessment results for the Gulf Coast; upcoming assessments and older assessment results and publications are also listed.
