Figure 1. Stable carbon isotopic composition of propane vs. ethane for gases from Mamm Creek field and a kinetic isotopic fractionation model for gases from a sample of the Cameo coal in the Upper Cretaceous Williams Fork Formation. The model results indicate a second source of gas with depleted carbon isotopic composition (possibly from the Mancos shale).
