Shale Oil an overview ScienceDirect Topics

The most common method of extracting shale oil is by surface mining. The in situ combustion process is used for extracting shale oil from far below the surface. The extracted shale oil then undergoes pyrolysis at 842 to 932°F (450 to 500°C) to produce oil shale (synthetic crude oil), shale gas and residue (solid).
