Abstract
Methods and systems are provided for quantifying contributions of gas mixtures in a reservoir compartment by way of isotopic analyses. Differing thermal maturities of the different gas mixtures allow estimation of the relative quantity of each gas mixture present in a total gas mixture. Thermal maturities may be estimated by reference to isotopic analyses of each contributing gas mixture and a commingled gas mixture resulting from commingling each of the individual source gas mixtures. This method may be carried out at various depths to determine relative contributions of each gas mixture to the total gas mixture as a function of wellbore depth. Advantages of certain embodiments include, but are not limited to, higher accuracies and ease of application as compared to conventional methods.
