Natural Gas Stable Isotope Analysis

13C / 12C and 2H / 1H

The most robust and detailed characterization of hydrocarbon gas molecules available is accomplished using stable isotope analysis. Hydrocarbon gas composition analysis is combined with stable isotope analyses to characterize the genetics of the gas. The naturally occurring hydrogen and carbon isotopic tracers of C1 - C5 hydrocarbon gas molecules are remarkably useful because the relative abundance of 12C and 13C or 2H and 1H in a gas depends on the various processes involved in the generation and subsequent migration or alteration of the hydrocarbon gases. For thermogenic gases, these data have been correlated extensively to the isotopic composition of the organic source material and the thermal maturity at which those molecules were generated, which is critical to the understanding of a petroleum system and the carbon cycle itself. (James, 1990; Clayton, 1991; Schoell, 1983; Whiticar, 1994).
