| Summary: | The drilling exploration in the SW part of the Carpathian Foredeep, in the vicinity of the gas deposit and UGS Dolní Dunajovice encountered the influx of gas, water and oil in Carpathian, Eggenburgian sandstones and Upper Jurassic carbonates. Similar shows were observed in the region at the base of the Jurassic and Miocene in older exploration wells. The new interpretations of 3D seismic and 2D profiles provide a new geological model integrated with petrophysical properties and geochemistry. A molecular and isotopic composition of gas indicates its mixed bacterial and thermal origin. Biomarkers in the new oils suggest a close genetic relationship to the Upper Jurassic marls and economically successful oil accumulations in the southern part of the south-eastern margin of the Bohemian Massif. The new findings increase the prospects of finding new structures with oil and gas accumulations in this region. |
