What is oil shale?
Oil shale is a kind of rock that contains kerogen, a waxy substance that gives off liquid when heated. Not all oil comes from oil wells that bring oil up from underground pools.
Much of the world’s supply of oil is found in a kind of rocks formed of tightly packed clay, mud and slit. This rocks is called oil shale.
Actually, this shale does not contain oil. It contains “kerogen” a waxy material which, when heated, gives off a liquid oil.
To get the oil from the kerogen in the oil shale, the shale “ore” is mined and crushed. Then it is heated in a furnace called a retort. One ton of oil shale may yield from 10 to 50- or-more gallons of crude oil.
When it has been refined, the oil can be separated into gasoline and other petroleum products, just as oil from oil from oil wells is separated.
Shale oil is not widely used because it is expensive to make. But as the world ‘s supply of oil diminishes, oil shale may someday provide an important source of oil for all of our machinery. – Dick Rogers
