A process and apparatus for recovering oil from an oil-bearing formation which comprises the steps of injecting into the oil-bearing formation a heated aerosol fog of organic chemicals which are soluble in oil, the fog preferably being at an elevated temperature and pressure. The heated aerosol fog penetrates the formation dissolving caked oil and oil trapped within the formation thereby increasing its permeability. The dissolved oil is extracted from the formation along with the injected chemicals and the chemicals are thereafter separated from the oil.
