“…Geochemical studies (Creaney et al, 1994;Li et al, 1998;Fowler et al, 2001) documented that the organic geochemical composition of the Duvernay Formation extracts is quite similar to most of the crude oils found within the Leduc-Nisku intervals along the Rimbey-Meadowbrook and Bashaw reef trends. In fact, geochemical oilsource correlations have demonstrated that the Leduc and Nisku oils are almost all sourced from the Duvernay Formation with probably only a very small contribution of the Nisku source to the Nisku oils (Rostron, 1997;Li et al, 1998;Harris et al, 2003).…”

The rhenium-osmium (Re-Os) geochronometer has been applied to many petroleum systems worldwide. However, it is debated if the Re-Os systematics in petroleum actually records the timing of oil generation. Here, we investigate the Re-Os isotope systematics of the Duvernay petroleum system in the Western Canada sedimentary basin, which has been shown to be a relatively simple petroleum system that is associated with oil generated during the Late Cretaceous-Early Eocene Laramide orogeny from a single source. The organic geochemistry of the Duvernay oils (pristane/phytane ratios of ~1.5, smooth homohopane profile, C 29 >C 27 >C 28 regular sterane distribution, and predominance of diasteranes over regular steranes) strongly suggest the oil source to be that of Type I-II marine organic matter of the Late Devonian Duvernay Formation. The asphaltene fraction Re-Os isotope data of the Duvernay oil yield an age of 66 ± 31 Ma, which is in excellent agreement with the timing of the main-stage hydrocarbon generation of the Duvernay Formation based on basin models. Further, the similarity between the 187 Os/ 188 Os compositions of the Duvernay Formation source rock (0.46 to 1.48) and the oil (0.55 to 1.06) at the time of oil generation supports the hypothesis that the 187 Os/ 188 Os composition of an oil is inherited from the source unit at the time of oil generation, and therefore shows no, or limited influence from interaction with basin fluids. This study supports that the Re-Os isotope systematics of an oil can yield the timing of oil generation, and be used to trace its source.

“…Harris et al [124] reported on the analysis of 27 oils (from central and southern Alberta) using a technique combining SPME and GC/IRMS. Using this technique, the 27 oils could be classified into six groups based on the carbon isotope ratios of individual petrol range compounds (C 5 -C 10 ).…”

“…Early studies of the stable carbon isotopic composition of crude oils, natural gases, and petroleum source rocks suggested that the isotopic compositions of individual petroleum hydrocarbons are generally inherited from the kerogens from which they are derived (Schoell, 1984). However, numerous theoretical, experimental, and field -based studies have since shown that variations in thermal maturity can significantly affect the compound-specific ␦ 13 C composition of petroleum hydrocarbons (Clayton, 1991a;Clayton, 1991b;Clayton and Bjorøy, 1994;Berner and Faber, 1996;Cramer et al, 1998;Lorant et al, 1998;Rooney et al, 1998;Harris et al, 2003). In one instance, Clayton and Bjorøy (1994) found that 50 to 90% of the carbon isotope variation in individual compounds from four North Sea oils was due to differences in thermal maturity.…”
