In the upper Miocene-Pliocene post-rift phase of the evolution of the Pannonian basin, several interconnected interior sags developed accompanying the thermal cooling of the lithosphere. In the Hungarian part of the these interior sags, commercial scale oil and gas production began in 1937. More than 6,500 wells were drilled, equivalent to a total of 13 million m combined footage. In the last few years, several areas in the Pannonian basin were subjected to more detailed and modern exploration than in previous years. Both up-to-date seismic reflection profiling and detailed sedimentological and geochemical analysis guided the drilling of several deep (more than 4,000 m) holes. Geochemical modeling of source rock maturation indicates that the Paleozoic-Mesozoic rocks reached the oil window in the Neogene, and these add to the already known Neogene-age hydrocarbon resource potential of the Pannonian basin. Furthermore, seismic stratigraphic interpretations revealed the characteristics of prodelta-delta plain sequences in the Neogene fill, that also have source rocks associated with them. The presentation, using seismic profiles and paleogeographic maps, will introduce and discuss the Neogene structural-stratigraphic evolution of the Pannonian Basin in regard to source rocks reservoirs, seals, and traps. Modeling generation and migration of hydrocarbons was used to rank the seismically identified structural and stratigraphic prospects. Using these new approaches and models, new exploration targets have emerged in the Pannonian basin that may be explored for many more years.
