Abstract
A process for recovering carbonaceous organic material from a subterranean formation containing carbonaceous organic material which comprises introducing into the formation a cyclohexene or cyclohexadiene, maintaining contact between the carbonaceous organic material and the cyclohexene or cyclohexadiene for a time and at a temperature sufficient to obtain carbonaceous organic material of reduced viscosity and then recovering carbonaceous organic material of reduced viscosity.
