Geological Characteristics of the Oil Fields in the Sloven ian Part of the Pannonian Basin

In the Slovenian part of the Pannonian basin the oil-gas field Petišovci, the gas fields Dolina and Gančani, and the oil fields Filovci, Bakovci and Bukovci were discovered. With the exception of Petišovci, the mentioned fields arecurrently not productive. On this basis, and as a consequence of recent results of oil geological investigations, the lithostratigraphic description of the Neogene beds of this part of the Pannonian basin is presented, together with occurrences or source rocks in the given stratigraphic horizons, as well as the structural charactcristics or the territory. The results highlight the somewhat higher potential of certain areas, which is also of importanceeconomically.
