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.
Using the Fischer assay measure of oil yield, we estimated a total of 1.44 trillion barrels of oil in three assessed units. There is currently no economic method to recover oil from this geologic unit.
