Abstract

The Makó trough in Hungary is a sedimentary depression formed in the extensional Pannonian basin during the last 15-20 Ma. It represents a young HT/HP system with >6 km thick basin fill and has been recognized as the location of major unconventional hydrocarbon resources. Such accumulations are regarded as “unconventional” when economic production is only possible by means of some sort of stimulation technique, usually hydraulic fracturing. Hydrocarbons in this setting do not accumulate conventionally in structural or stratigraphic traps, but in pervasive cells. Due to the geological setting of the Makó trough, the hydrocarbon cell forms a relatively continuous zone marked by considerable internal lithological and petrophysical variability. Due to its novelty and complexity, the exploration of this unconventional resource demands the concurrent application of a wide range of geological and geophysical methods. Evaluation of such petroleum systems strongly rely on the reconstruction of the tectonosedimentary evolution of the host basin, the understanding of the subsidence, burial, thermal and maturation history, and the timing and mechanism of hydrocarbon generation and related abnormal pressure development. In this contribution, highlights are on the latest models for basin evolution and petroleum system development are presented.
