Abstract
Heavy oil from underground oil sands or tar sands is liquified with recirculation of superheated water and when brought to the ground surface is then wet oxidized for its heat value. The sulphur content of the products of wet oxidation is then wet reduced to elemental sulphur for by-product. The carbon dioxide gas generated as a product of wet oxidation is injected back to wells for its value as a diluter of the oil. Heat produced from wet oxidation is used for useful work at wells site.
