  • System and method for determining natural hydrocarbon concentration utilizing isotope data
    Patent number: 11867682
    Abstract: A method for determining a hydrocarbon concentration from drilling fluid includes pumping the drilling fluid into a wellbore and circulating a sample of the drilling fluid uphole from the wellbore so that ?13C isotopic signatures can be determined for one or more hydrocarbon components and for methane in the sample where the methane includes natural methane originating from the earth formation and artificially-produced methane caused by drill bit metamorphism (DBM). A processor is adapted to determine the concentration of the natural methane in the sample based in part on the ?13C isotopic signatures which may be performed during the drilling of the wellbore.
    Type: Grant
