Abstract

The results of carbon isotope ratio measurements for 79 natural gas occurrence of Hungary were interpreted. On the base of carbon isotope ratios characteristic to methane and its distribution with depth genetic groups were determined which differ from each other in the character of the generation process and the type of organic material. The change of carbon isotope ratio with depth and the degree of transformation can be attributed to the common effect of kinetic isotope effect and vertical migration in the case of the methane component of natural gases of thermogeneous origin arising from the same type of organic material and trapped in Neogene reservoir rocks. Carbon isotope ratios referring to strong vertical migration are in general in connection with the high carbon dioxide content of natural gases. It could have been established from the carbon isotope ratios of carbon dioxide that the bulk of carbon dioxide originated from the deeper zones of the lithosphere as a consequence of regional metamorphism of carbonate rocks.
