Oil shale formation takes place in a number of depositional settings and has considerable compositional variation. Oil shales can be classified by their composition (carbonate minerals such as calcite or detrital minerals such as quartz and clays) or by their depositional environment (large lakes, shallow marine, and lagoon/small lake settings).
(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 ...
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 ...
Oil shale retorting followed in 1881 by utilization of "D" retorts. The plant closed before 1900. [6] By 1892, about 100,000 tonnes of oil shale were being processed In Australia annually. [7] In 1896, the New South Wales Shale Oil Company expanded its activities to Torbane near Capertee, New South Wales.
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).
As the crisis in Syria reaches the boiling point, sending oil higher, it's time to rethink America's energy independence. It's estimated that 30% of the country's undiscovered oil and gas reserves ...
That equates to an estimated two-thirds of the country's shale oil reserves. The 1,750 square-mile formation is in central California which could make it a bit more difficult to recover, given ...
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 .
