Table 1 Light hydrocarbon data taken from Whiticar and Snowdon.[2] δ13C values are averages of multiple analyses, δ13C [C6] and δ13C [C7] (the last two columns) were calculated from eqn. (2) and eqn. (3), respectively with coefficients a, b and c calculated from the respective C6 concentrations normalized to 1 and coefficients d, e, and f calculated from the respective C7 concentrations normalized to 1. The amount of 2-MP (in %) was taken from column five of Whiticar–Snowdon's Table 3 labeled 3DMC4 incorrectly. Six oils in Whiticar–Snowdon's set of 42 oils were excluded from this set: Brazeau PA was excluded because of possible thermochemical sulfate reduction (TSR), Fusilier was not included because of low n-alkanes and thus possible biodegradation. Four other oils were excluded because they did not contain the full suite of data required to calculate δ13C [C6] and δ13C [C7]: Brazeau River F, Chester, Foothills 8, and Manyberries.
