Procesy generowania i ekspulsji węglowodorów – rola siarki organicznej: zastosowanie metody dla potrzeb poszukiwań naftowych

Determination of organic sulphur content in kerogen is necessary element for precise assay of its genetic type and for modelling of time position of "oil window" and other hydrocarbon generation phases for individual source rocks during geological development of petroleum basin. Presence of organic sulphur in kerogen within clayey-mudstone Menilite strata of the Flysch Carpathians and carbonate Main Dolomite strata of the Polish Lowlands prove that within these source rocks early process of generation of liquid hydrocarbons on lower stage of kerogen transformation was possible. Up to now this immature kerogen was considered incapable for generation of liquid hydrocarbons. Presence of type II-S kerogen in Menilite strata of Skole unit of the Flysch Carpathians indicates that oil was generated during sedimentation stage of development of basin of the tectonic unit.
