- Abstract
The Oligocene Tard and Kiscell formations represent classical source rock examples in the Hungarian part of the Danube Basin. Similar sediments recorded in the Slovak part of the Danube Basin were studied by Rock-Eval pyrolysis in this paper, while their stratigraphic position was supported by the foraminiferal and nannoplankton biostratigraphy. Result obtained from MOD-1 and MOD-2 wells show that the Oligocene sediments are immature (Tmax < 432 °C). They contain mixed kerogen type II/III as well as coaly matter and show lower hydrocarbon potential (TOC 1.38–1.57 wt %; HI 164–345 mg HC/g TOC; PP 4.60–5.59 mg HC/g rock). Composition of organic matter confirms correlation with Hungarian Kiscell Fm. The Neogene sediments are immature and have a poor petroleum potential. One exception is present in Pannonian sediments with kerogen type II/III, relatively high TOC (0.98 wt %) and hydrogen index (HI= 424 mg HC/g TOC). Fair petroleum potential (PP 4.36 mg HC/g rock) shows that some horizons (Tortonian) can be potentially perspective in the deeper buried part of the basin.
