Teleki P.G., Mattick R.E, Kókai J. (eds.) Basin Analysis in Petroleum Exploration. A case study from the Békés Basin, Hungary

Dordrecht: Springer Science+Business Media, 1994. — 330 p. — ISBN: 978-94-010-4412-7.Basin analysis is a comprehensive approach to decipher the geological evolution of a basin by constructing the stratigraphic framework and facies relationships, by mapping and understanding the geological structures in light of their historical development, and by examining the physical and chemical properties of rocks and their sedimentological and petroleum attributes. The purpose of the analysis is to identify potential source rocks and reservoir rocks, and to evaluate the maturation, generation, migration, and entrapment of hydrocarbons in a sedimentary basin. This book is a compendium of chapters reporting on the results of a basin analysis of the Békés basin, a subbasin of the Pannonian Basin system in Hungary. The study, carried out in 1986-87, was conducted at the request of the Hungarian Oil and Gas Company (then called OKGT, and now MOL Ltd.) and the World Bank as part of a broader program designed to improve oil and gas exploration in Hungary. The work was accomplished by a joint effort of the Hungarian Oil and Gas Company and the U.S. Geological Survey.Foreword
