This patent describes an improved method for producing hydrocarbonaceous fluids from oil shale where the oil shale is hydrotreated under hydrotreating conditions in a reactor in the presence of a hydrogen donor solvent. The method includes (a) conducting the hydrotreating reaction within a reactor in a substantially air free atmosphere which produces hydrocarbonaceous fluids and an oil shale containing a hydrogen donor modified organic content; (b) separating the hydrocarbonaceous fluids, including the hydrogen donor, from the oil shale containing the hydrogen donor modified organic content; (c) contacting the oil shale with an aqueous chemical water-flooding fluid which removes the modified organic content from the shale by flotation; (d) recovering the modified organic content from the aqueous waterflooding fluid; (e) separating the modified organic content from the aqueous surfactant; and (f) mixing the modified organic content with a hydrocarbonaceous solvent which reduces the viscosity of the modified organic content to facilitate transportation.
