Abstract

Summary

The central Hungarian Paleogene Basin has been a focus of hydrocarbon exploration for more than hundred years and numerous pools have been discovered. The basin is filled by up to ∼4km of Eocene to Pliocene strata resting unconformably a seismic basement of Triassic limestones and Paleozoic metasediments. Eocene to Oligocene source rocks expulse hydrocarbons into fractured Triassic and Jurassic limestones, as well as Eocene, Oligocene and Miocene clastics. The main objective of this evaluation was to improve the understanding of the structural styles, the structural timing and, ultimately, to identify exploration opportunities.

We present new seismic interpretations, new static structural models, new kinematic restorations, new core and outcrop observations. The following data was used: Digital terrain data, newly merged and reprocessed 3D seismic data, newly reprocessed 2D seismic data, well data from ∼50 wells (formation tops, petrophysical data), outcrop data and core data.

The key results are a more detailed understanding of the structural architecture and of the linkage between first order structures and prospective second-order structures. Kinematic restorations reveal that part of the structural relief was in place at Oligocene times, was overprinted during Mio-Pliocene times and was affected to a minor degree by widespread neotectonic activity.
