Previous HitSequenceNext Hit Stratigraphic and Petroleum Geologic Model of the Brakish and Nonmarine (Late Middle Miocene - Pliocene) Strata of the Pannonian Basin, Hungary

Gabor A. Vakarcs, Peter R. Vail, Ferenc Horvath

The Pannonian Basin became isolated from the world sea at 11.5 Ma and formed a large lake. It offers a good opportunity to show the distribution of depositional Previous HitsequencesNext Hit, source rocks and reservoirs within a lacustrine basin.

The Middle Miocene-Pliocene infill of the back-arc Pannonian Basin of Hungary involved the advance of deltas from the basin margins. Twelve composite depositional Previous HitsequencesNext Hit were identified, based on interpretation of 7000 km 2D multifold seismic sections and 130 hydrocarbon exploration and production wells. The number and the age of these depositional Previous HitsequencesNext Hit, dated by magnetostratigraphic data, correspond well to that of the published global eustatic curve. All of the depositional Previous HitsequencesNext Hit are complete Previous HitsequencesNext Hit, containing braid or self margin, transgressive and highstand systems tracts. These Previous HitsequencesNext Hit are mostly Type-1 depositional Previous HitsequencesNext Hit and are built up from order Previous HitsequenceNext Hit and/or parasequence sets. The identified depositional Previous HitsequencesNext Hit were correlated to create paleogeogra hic maps.

The lacustrine depositional Previous HitsequencesNext Hit show the same stratal patterns as the marine ones. However, deposited within slightly separated subbasins, these lacustrine Previous HitsequencesNext Hit are more sensitive to changes in tectonic subsidence, eustasy, sediment supply and climate, in a lateral direction. There are several identified fourth-order Previous HitsequencesNext Hit in which Type-1 and Type-2 behavior can be seen in the same Previous HitsequenceNext Hit. These are "apparent Type-2 Previous HitsequencesNext Hit", developed in response to variations in sediment supply.

Using Previous HitsequenceNext Hit stratigraphy to recognize Previous HitsequenceTop boundaries, stratigraphic traps and source rocks and effects of late-stage compression, has resulted in enhanced input data to simulate the subsidence, thermal, and maturation histories of the Pannonian Basin.
