We estimated a total of 1.525 trillion barrels of oil are in place in seventeen oil shale zones in this area using a geology-based assessment methodology.
Using a geology-based assessment methodology, we estimated a total of 1.32 trillion barrels of oil in place in eighteen oil shale zones in this Eocene geologic unit.
Estimates of additional energy resources present within known oil and gas fields using statistical analysis that includes geology and engineering practices in addition to growth trends in production data.
We used mathematical models to estimate the likely increases in the estimates of the amount of oil and gas technically recoverable from existing known large fields outside the US.
We estimated potential, technically recoverable oil and gas resources for source rocks of the Alaska North Slope. Estimates range from zero to 2 billion barrels of oil and from zero to nearly 80 trillion cubic feet of natural gas.
We estimated means of 4.7 billion barrels of undiscovered oil and 227 trillion cubic feet of undiscovered natural gas in three major offshore petroleum basins using a geology-based assessment methodology.
We estimated means of 19 billion barrels of technically recoverable undiscovered conventional oil and 370 trillion cubic feet of undiscovered conventional natural gas resources in this area using a geology-based assessment methodology.
We estimated mean volumes of undiscovered conventional resources in this area at 14.9 billion barrels of oil, 87.6 trillion cubic feet of natural gas, and 1.4 billion barrels of natural-gas liquids using a geology-based assessment methodology.
We estimated means of 126 billion barrels of oil and 679 trillion cubic feet of undiscovered natural gas in 31 geologic provinces of South America and the Caribbean using a geology based assessment methodology.
We estimated means of 86 billion barrels of oil and 336 trillion cubic feet of undiscovered natural gas resources in this area using a geology-based assessment methodology.
