Using a combination of techniques to control or direct the use of resources and limit population size to reach a predetermined goal, such as sustainability.
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.
The electric power generation potential from identified geothermal systems is 9,057 Megawattselectric (MWe), distributed over 13 states. Undiscovered resources are estimated to provide an additional 30,033 MWe.
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 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.
