Abstract
Described herein are methods and techniques that utilize molecular geochemistry and isotopic signatures to monitor microbial enhanced gas and oil recovery operations. The methods and techniques utilize multiply substituted isotopologue signatures, clumped isotope signatures, and/or position-specific isotope signatures of one or more byproducts of the microbial stimulation techniques to determine the effectiveness of a microbial stimulation technique.
