ResumoThe carbon isotopic ratios obtained from Athabasca bitumen, asphaltene and maltene have the same value δ13C = −29.6 per ml. The corresponding values in the Cold Lake deposits are −30.6, −30.0 and −31.6 per ml. The ratios determined for methane collected from the oil sand and its fractions are about 15 per ml lower than the above values. It appears that the Athabasca and Cold Lake Reservoirs have similar histories.
