  • Isotopic identification of production by individual formations in commingled gas wells
    Patent number: 8316934
    Abstract: A computer system and computerized method for allocating production among multiple formations produced by a hydrocarbon well, using isotopic concentration analysis. According to an aspect of the system and method, multiple single-formation isotopic concentration measurements of multiple hydrocarbon gases are taken from each formation. Within each formation, groups of similar isotopic concentration values are defined, and are mapped to geographic regions of the formations. Mixing equations are developed between regions of the different formations, for use in allocating production for a well intersecting those regions. According to another aspect of the system and method, allocation among three or more formations is performed using Monte Carlo analysis of an underspecified mixing equation, and at a measured isotopic concentration value for the commingled flow from the well.
