A process is described of producing water gas and extracting oil from oil shale which consists in igniting a confined body of shale at its upper surface, admitting air for combustion above the confined ignited body, drawing the steam and combustion gases downwardly through the shale body to decompose the carbonaceous matter and kerogen contained within the shale by the heat treatment to produce water gas and hydrocarbon vapors. The water gas is used to generate the steam. The oil released from the shale by the heat treatment is collected, and the hydrocarbon vapors from the water gas are condensed. The water gas is collected. The admission of air for combustion to the upper surface of the confined body is controlled in accordance with the temperature of the water gas.
