Claim One:
1. A method of producing hydrocarbons comprising: (a) obtaining one or more samples from a well in a region of interest; (b) analyzing the one or more samples to determine a baseline isotopic signature, wherein the baseline isotopic signature comprises one or more of multiply substituted isotopologue signatures, clumped isotope signatures, and position-specific isotope signatures; (c) performing a microbial stimulation operation on the region of interest; (d) obtaining one or more post-stimulation samples from the well; (e) analyzing the post-stimulation sample to determine an induced isotopic signature, wherein the induced isotopic signature comprises multiply substituted isotopologue signatures, clumped isotope signatures, and/or position-specific isotope signatures; (f) comparing the baseline isotopic signature and the induced isotopic signature; (g) using the comparison to determine whether the type of hydrocarbons being produced from the well has changed, wherein the type of hydrocarbons being produced from the well comprises thermogenic hydrocarbons, biogenic hydrocarbons, and induced biogenic hydrocarbons; and (h) updating or refining the microbial stimulation operation based on the type of hydrocarbons being produced from the well.
