Oil Shale Extraction | HowStuffWorks
Oil shale must be mined using either underground- or surface-mining methods. After excavation, the oil shale must undergo retorting . This is when the mined rock is exposed to the process of pyrolysis — applying extreme heat without the presence of oxygen to a substance, and producing a chemical change.

The Scottish Oil-Shale Industry
Oil-shales were predominantly formed in aquatic environments, either seas or lakes, and occur world wide. They are carbonaceous, fine-grained sedimentary rocks, rich in organic matter, which produce shale oil when heated in retorts. Historically they were burnt in domestic fires, like coal, but in the late nineteenth century they were...
