World Oil and Gas Resource Assessments Active
The USGS World Energy Project conducts geologic studies that provide an understanding of the quantity, quality, and geologic distribution of world oil and gas resources. Our geologic studies are conducted in an impartial manner and are performed in collaboration and partnership with energy experts within and outside government. Through synthesis and improved understanding of global oil and gas data, we shall establish a geologic basis for predicting energy production trends, we shall discuss logical implications and consequences of energy occurrence for public policy, and we shall provide for the education of society about energy issues.
Assessment Overview
The USGS assesses potential for undiscovered oil and gas resources in priority geologic provinces in the World. This website highlights conventional and unconventional (continuous) oil and gas resources (such as shale gas) for more than 170 basins.
