Areas susceptible to inundation during landfall of Hurricane Rita are assessed by comparing lidar-derived dune elevations to simulated storm surge values. Results shown on pictorial maps.
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 mean volumes of 13.4 trillion cubic feet of potential technically recoverable shale gas and 0.5 billion barrels of technically recoverable shale oil resources in this area using a performance-based geologic assessment methodology.
Using a performance-based geologic assessment methodology, we estimated a technically recoverable mean volume of 6.1 trillion cubic feet of potential shale gas in these areas.
The mean total volume of potential additional oil resources that might be added using improved oil-recovery technologies was estimated to be about 2.7 billion barrels of oil.
The mean total volume of potential oil reserves that might be added in the nine fields using improved oil-recovery technologies was estimated to be about 6.5 billion barrels of oil.
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 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.
