Because of governmental changes an entire region of Central Europe has received exploration scrutiny not possible during the past 40-50 years. This entire area - Hungary, Czechoslovakia, Romania, Bulgaria, Yugoslavia, Albania, Poland, and East Germany - is tectonically related. Yugoslavia, although not under the same restrictions, is also considered in the same tectonic setting. Therefore, these countries can be expected to reflect some of the same stratigraphy, source rock, reservoir, trap and field types, and production history. Much of the region can be considered frontier while other parts mature. Production from all is about 55,000 T/D, 380,000 BO/D and 63.1 Bm{sup 3}/yr, 2,203 Bft{sup 3}/yr. Major source rocks have been identified as Tertiary-Oligocene, Miocene-Mesozoic, Triassic, Jurassic, and Cretaceous. Carboniferous coal sequences are considered source for the Permian. The East European platform and Tethyian plates are the foundation of the Central Europe states. Plate collisions during the late Mesozoic and into the Tertiary affected the Carpathian, Balkans, Dinarides, and Helenide Mountain chains. Mesozoic and Tertiary foredeep deposits have been proven productive from normal-, thrust-, and wrench-faulted anticlinal structures. Paleozoic, Mesozoic erosional remnants, and Tertiary lacustrine and deltaic stratigraphic deposits are the major productive reservoirs in the Pannonian basin. Permian shelf andmore » reefal deposits are found in such areas as the Permian Shelf in Eastern Germany and Poland. Reefal plays may be found in Bulgaria and Romania offshore.« less
