Assessment of Undiscovered Petroleum Resources of Southern and Western Afghanistan, 2009 [More info]: We estimated mean undiscovered resource volumes of 21.55 million barrels of oil, 44.76 billion cubic feet of non-associated natural gas, and 0.91 million barrels of natural gas liquids in the western Afghanistan Tirpul Assessment Unit.
Assessment of Undiscovered Petroleum Resources of the Barents Sea Shelf [More info]: We estimated mean undiscovered, conventional, technically recoverable petroleum resources in the Barents Sea Shelf to be more than 76 billion barrels of oil equivalent using a geology-based assessment methodology.
Assessment of Undiscovered Petroleum Resources of the North and East Margins of the Siberian Craton, Russian Federation [More info]: We estimated the mean undiscovered, conventional petroleum resources at 28 billion barrels of oil equivalent, including approximately 8 billion barrels of crude oil, 106 trillion cubic feet of natural gas, and 3 billion barrels of natural gas liquids.
Assessment of in-place oil shale resources of the Green River Formation, Greater Green River Basin in Wyoming, Colorado, and Utah [More info]: 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.
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.
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 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.
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.
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.
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.
