One of the main goals of the Gulf Coast Geologic Energy Assessments and Research (GEAR) project is to conduct assessments of undiscovered, technically recoverable petroleum resources of the U.S. Gulf Coast region. This goal is in accordance with the Energy Policy and Conservation Act (EPCA) and is performed in collaboration with the USGS National Oil and Gas Assessment project. These high-quality, scientifically unbiased resource assessments provide crucial information to stakeholders and decision makers at the local, State, and Federal levels.
The hydrocarbon resource assessments in the U.S. Gulf Coast focus on the onshore and State waters portion of this region. The offshore Gulf of Mexico basin outboard of the State-Federal boundary is within the purview of the Bureau of Ocean Energy Management. These geologic-based quantitative assessments use different methodologies for 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 are dispersed throughout the matrix of the host rock unit.
