The aim of this chapter is to describe the key elements of the petroleum systems responsible for the accumulation of hydrocarbons as well as the most significant discoveries in the Ukrainian Carpathian Foredeep. The petroleum potential of the foredeep is contained in the Jurassic to Miocene sedimentary rocks. A total of 40 gas fields, 4 gas-condensate fields, and 2 oil fields have been discovered in the foredeep to date. Several of the most typical fields have been described in this chapter. These fields produce from the Upper Jurassic to middle Miocene reservoir rocks, sealed by the rocks occurring throughout the Mesozoic-Cenozoic sedimentary column. The traps can be summarized as follows: stratigraphic trapping beneath unconformity; stratigraphic trapping above unconformity; thrust-related trapping; and normal-fault-related trapping. Recently, the basin is at a mature stage of exploration, but new exploration opportunities continue to exist.

This volume of 30 chapters authored by 107 geologists and geophysicists from Austria, Czech Republic, Hungary, Poland, Romania, Slovakia, Ukraine, United Kingdom, and the USA provides a comprehensive and understandable account of geology and hydrocarbon resources of the entire Carpathian system from northeastern Austria to southern Romania, including the Neogene foredeep, the foreland platform both in front and beneath the thrust belt, the Carpathian thrust belt, and the late and post orogenic intermontane basins. Principal chapters on regional geology are supplemented by thematic contributions on geodynamic reconstructions, regional geophysical investigations, hydrocarbon systems, and case studies of major oil and gas fields. To date, close to 7 billion barrels of oil and more than 53 trillion cubic feet of natural gas have been produced from the entire Carpathian system. Additional new reserves may be found, especially at deeper structural levels below the Neogene foredeep and the thin-skinned Carpathian thrust belt. Seventeen chapters of Memoir 84 have been printed in full. The remaining chapters have been printed as abstracts only, with the full paper for all 30 chapters as .pdf files on the CD-ROM in the back of this publication. The publication is intended as a source of information to schools, governmental and private institutions, oil companies, and potential investors.
