Abstract
This invention includes methods of recovering hydrocarbons from oil shale, and sub-surface oil shale recovery arrangements for recovering hydrocarbons from oil shale. In one implementation, a sub-surface oil shale recovery arrangement for recovering hydrocarbons from oil shale includes a bore hole extending upwardly from a subterranean room into oil shale, with at least an upper part of the room being received within the oil shale and includes a wall through which the bore hole extends. The bore hole includes a lowest portion within the oil shale and an upper portion within the oil shale. A heating energy source extends from the subterranean room into the bore hole along the lowest portion and along the upper portion, insulation and/or cooling is received radially about the heating energy source extending along the lowest portion. Other aspects are contemplated.
