PDF A methodology for conducting national-scale alluvial diamond resource potential and production capacity assessments, with a focus on artisanal mining [More info]
Geologic evidence, combined with geographical data and analyized through a geographic information system allows us to compare production statistics with likely resource estimates.
PDF An estimate of undiscovered conventional oil and gas resources of the world, 2012 [More info]
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.
An evaluation of the science needs to inform decisions on Outer Continental Shelf energy development in the Chukchi and Beaufort Seas, Alaska [More info]
We need refined regional understanding of climate change, effective oil-spill risk assessment, preparedness, and response, an analysis of cumulative effects (natural and human), better geospatial data for the area, in an integrated approach.
PDF Assessment of Gas Hydrate Resources on the North Slope, Alaska, 2008 [More info]
We estimate that there are about 85 trillion cubic feet (TCF) of undiscovered, technically recoverable gas resources within gas hydrates in northern Alaska.
PDF 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.
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.
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 shale oil and tight sandstone gas resources of the Assam, Bombay, Cauvery, and Krishna-Godavari Provinces, India, 2013 [More info]
Using a well performance-based geologic assessment methodology, we estimated a technically recoverable mean volume of 62 million barrels of oil in shale oil reservoirs, and more than 3,700 billion cubic feet of gas in tight sandstone in this area.
