Shale Oil

Mining oil shale can be either surface mining or in situ retorting. In surface mining the oil shale is transported to aboveground facilities. There the oil shale is crushed and loaded into a reactor known as a retort, where the temperature is increased to about 400–500°C to decompose the kerogen and release the shale oil.
