ABSTRACT:
The invention comprises a method and apparatus for recovering oil from so-called depleted oil fields and also from tar sands. A pressurized, heated, non-aqueous gas, such as carbon dioxide, is continuously flowed through a channel which is in heat exchange relationship with an oil-bearing matrix, thus reducing the viscosity and mobilizing the oil in the sensible boundary region. Mobilized oil flows to a collection reservoir from which it is then produced.
