Some of these known methods require the mining, crushing and retorting of the oil-containing rocks, whereas in other methods oil is recovered by processing, i.e. by retorting or extracting. Thus, for example, it is known to recover kerogen from oil shale by retorting, which can be performed like the swealing of coal.
