Abstract
The present invention relates to a novel method for improving the recovery of hydrocarbon fluids from oil shale. The method comprises treating a mixture of oil shale and hydrocarbon fluid at a temperature below the retorting temperature of the shale and for a period of time sufficient to recover product hydrocarbon fluids in amount equivalent to at least 100 percent Fischer Assay.
