The effects of microbiological degradation on several conventional pooled oils and on oil sand bitumens were studied. Samples of a Prudhoe Bay (PB) crude were examined for comparison with Lower Cretaceous pooled oils such as Bellshill Lake (BH) and Lloydminster (L1) along with oil sand bitumens from the Cold Lake (CL), Peace River (PR) and Athabasca oil sands. The gas chromatography-mass spectroscopy processes reveal close similarities between the biodegradation products of the oil from Prudhoe Bay and the oil sands and heavy oils of Alberta. A common source for all of these oils is not postulated although they probably share a similar origin and diagenetic history. These results do not give a direct indication as to the maturity and thermal history of the Alberta oil sands but they do support the hypothesis that the oil sands, and some conventional crude oils found in the reservoirs of the Lower Cretaceous formation of Alberta share a common origin and are related by their degrees of biodegradation.
