Sažetak
The southern, marginal part of the Pannonian Basin, located in the Republic of Croatia is a hydrocarbon producing area consisting of gas, gas-condensate and small oil-gas fields. Research of chemical components and isotopic composition of carbon and hydrogen of the natural gases shows that they are predominantly thermogenic. With respect to source organic facies, there are two main types of gases: condensate-associated gases, with - 41.8 to - 31.1‰ of  13C and with -157 to -167‰  D originating mostly from Lower-Middle Miocene clastic source rocks and petroleum-associated gases generated from Badenian to Pannonian source rocks with sapropelic organic matter, with – 47.9 to -46, 3‰ of  13C and heavier than -170‰ of  D. Mineralogical composition of reservoir rocks and specific thermodynamic conditions have a crucial impact on the formation of CO2 and H2S that are associated with most hydrocarbon accumulations.
