OIL SHALE

Oil shale is a fine-grained sedimentary rock, containing significant amounts of kerogen (a solid mixture of organic chemical compounds), from which liquid hydrocarbons can be manufactured. The name oil shale is something of a misnomer as the rock is not necessarily a shale and the hydrocarbon in it is not truly oil. Deposits of oil shale are located around the world, including major deposits in the United States. Global deposits are estimated as equivalent to 2.9–3.3 trillion (2.9–3.3 x 1012) barrels of recoverable oil.

Noun
1. shale from which oil can be obtained by heating
(hypernym) shale

Underground formation of a fine-grained sedimentary rock containing varying amounts of kerogen, a solid, waxy mixture of hydrocarbon compounds. Heating the rock to high temperatures converts the kerogen to a vapor, which can be condensed to form a slow flowing heavy oil called shale oil. See kerogen, shale oil.

A brown or black clastic source rock containing kerogen.
