 The focus of this contribution is twofold: (1) analysis of tectonic patterns of the entire Vienna Basin and its subthrust level which includes autochthonous Jurassic sediments; (2) further geological and palynofacial characterization of Mikulov Upper Jurassic marls with ultimate aim to get new insights into unconventional prospects within the Moravian part of the Basin. The deposition here has been largely controlled by strike-slip reactivations within faults of the principal displacement zone. Liquid and gaseous hydrocarbons generated within the Mikulov source rock formation supplied several conventional oil and gas plays in the Miocene reservoirs mostly laterally but also vertically. Vertical migration of hydrocarbons took place via releasing jogs or “windows” appeared in thrust belt damage zone because of transtensional reactivations of en échelon arranged fragments of the principal displacement zone. Our model suggests presence of considerable unconventional gas resource play existing in deep overpressured Mikulov compartment sealed by impermeable combination of overlapping flysch and multiple the Carpathian thrust belt’s sheets.
