Figure 6. Galimov-type plot of δ13C-isotopic composition. Typical standard deviations of carbon isotopic composition are ±0.1‰. Data fields for Berea and Ordovician oils from Ohio (OH) are from Cole et al. (1987). Samples are identified by well name and depth in feet. Modified from Parris et al. (2019) with permission of Kentucky Geological Survey. VPDB = Vienna Peedee belemnite.
