Oil shale - The Full Wiki

Oil shale, an organic-rich fine-grained sedimentary rock, contains significant amounts of kerogen (a solid mixture of organic chemical compounds) from which technology can be used to extract liquid hydrocarbons. The name oil shale is a misnomer as geologists would not necessarily classify the rock as a shale, and its kerogen differs from crude oil.
