Using a geology-based assessment methodology, we estimated means of 565 billion barrels of conventional oil and 5,606 trillion cubic feet of undiscovered conventional natural gas in 171 priority geologic provinces of the world, exclusive of the U.S.
We need refined regional understanding of climate change, effective oil-spill risk assessment, preparedness, and response, an analysis of cumulative effects (natural and human), better geospatial data for the area, in an integrated approach.
