Oil shale - Wikipedia
Oil shale is an organic-rich fine-grained sedimentary rock containing kerogen (a solid mixture of organic chemical compounds) from which liquid hydrocarbons can be produced, called shale oil.Shale oil is a substitute for conventional crude oil; however, extracting shale oil is more costly than the production of conventional crude oil both financially and in terms of its environmental impact.
