PDF Assessment of potential additions to conventional oil and gas resources in discovered fields of the United States from reserve growth, 2012 [More info]
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.
PDF Assessment of potential additions to conventional oil and gas resources of the world (outside the United States) from reserve growth, 2012 [More info]
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.
Assessment of potential coastal impacts: Hurricane Rita [More info]
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.
PDF Assessment of potential oil and gas resources in source rocks of the Alaska North Slope, 2012 [More info]
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.
PDF Assessment of potential shale gas and shale oil resources of the Norte Basin, Uruguay, 2011 [More info]
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.
PDF Assessment of potential shale gas resources of the Bombay, Cauvery, and Krishna-Godavari Provinces, India, 2011 [More info]
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.
PDF Assessment of potential unconventional Carboniferous-Permian gas resources of the Liaohe Basin eastern uplift, Liaoning Province, China, 2011 [More info]
We estimated a mean of 448 billion cubic feet of potential technically recoverable unconventional natural gas in this area.
PDF Assessment of remaining recoverable oil in selected major oil fields of the Permian Basin, Texas and New Mexico [More info]
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.
PDF Assessment of remaining recoverable oil in selected major oil fields of the San Joaquin Basin, California [More info]
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.
PDF Assessment of undiscovered conventional oil and gas resources of Bonaparte Basin, Browse Basin, Northwest Shelf, and Gippsland Basin Provinces, Australia, 2011 [More info]
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.
