    This thesis describes the geological structure of the Cieszyn-Andrychów-Żywiec area, where the Kowale the Carpathian Overthrust between two cities Cieszyn and Bielsko Biała. Data gathered from the borehole Kowale-2 indicate that the Carpathian Flysch reaches 315m depth, subsequently Miocene-Tortonian up to 820 m depth (Dębowiec Conglomerate 741-820m depth), beneath, there is Upper Carboniferous interval up to 1000 m depth. Gas is accumulated within three Miocene horizons, within combination of structurallithological traps. Kowale is a new gas field, in which production testing was very short, with two measured points. The main mineral resource is Miocene biogenic natural gas which originally comes from Upper Carboniferous coal beds. This is dry gas with low concentration of nitrogen and low or none concentration of condensate. Resources of natural gas were evaluated using the volumetric method inside three Miocene horizons. Also the dynamic method was used in order to calculate gas resources inside the first horizon, which is presently in the course of exploitation. The size of gas resources was assumed according to the volumetric method. Primarily, sum of geological resources, C category are 112 mln m3 whereas, recoverable reserves 101 mln m3.
