Gulf Coast Geologic Energy Assessments and Research Project
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.
The Gulf Coast GEAR project is part of the USGS Energy Resources Program with staff in Reston, Virginia at the Geology, Energy & Minerals Science Center and the Florence Bascom Geoscience Center; Denver, Colorado at the Central Energy Resources Science Center; and Anchorage, Alaska at the Alaska Science Center.
