The table below reports reserves by estimated amount of shale oil. Shale oil refers to synthetic oil obtained by heating organic material (kerogen) contained in oil shale to a temperature which will separate it into oil, combustible gas, and the residual carbon that remains in the spent shale. All figures are presented in barrels and metric tons.
The United States has the largest known deposits of oil shale in the world, according to the Bureau of Land Management and holds an estimated 2.175 trillion barrels (345.8 km 3) of potentially recoverable oil. [21] Oil shale does not actually contain oil, but a waxy oil precursor known as kerogen. There is significant commercial production of ...
The Reserves were initially under the control of the U.S. Department of the Interior, but in 1920, the U.S. Navy's Fuel Oil Office assumed responsibility for the Reserves. A year later, President Warren Harding placed the Reserves back under the Department of Interior, only to have the Teapot Dome Scandal force control back to the U.S. Navy. In ...
The United States Navy and the Office of Naval Petroleum and Oil Shale Reserves started evaluations of oil shale's suitability for military fuels, such as jet fuels, marine fuels and a heavy fuel oil. Shale-oil based JP-4 jet fuel was produced until the early 1990s, when it was replaced with kerosene-based JP-8. [32]
(The data below does not seem to include shale oil and other unconventional sources of oil such as tar sands. For instance, North America has over 3 trillion barrels of shale oil reserves, [ citation needed ] and the majority of oil produced in the US is from shale, leading to the paradoxical data below that the US will finish all its oil at ...
Accordingly, shale oil produced from oil shale should not be confused with tight oil, which is also frequently called shale oil. [ 3 ] [ 4 ] [ 5 ] A 2016 estimate of global deposits set the total world resources of oil shale equivalent of 6.05 trillion barrels (962 billion cubic metres) of oil in place . [ 6 ]
Global technically recoverable oil shale reserves have recently been estimated at 2.8 to 3.3 trillion barrels (450 × 10 ^ 9 to 520 × 10 ^ 9 m 3) of shale oil, with the largest reserves in the United States, which is thought to have 1.5–2.6 trillion barrels (240 × 10 ^ 9 –410 × 10 ^ 9 m 3).
This is a list of countries by recoverable shale gas based on data collected by the Energy Information Administration agency of the United States Department of Energy. [1] Numbers for the estimated amount of recoverable shale gas resources are provided alongside numbers for proven natural gas reserves .
