The modern industrial hydrocarbon exploration started in the Boryslav-Pokuttya zone in 1904. In 1905, the well Oil City produced approximately 30001 of oil/day and 900,000 m3 (31.8 mmcf) of gas per day from the Oligocene Boryslav sandstone, a very significant amount at the beginning of 20th century. After the Second World War, the Dolyna and Bytkiv-Babche oil fields were discovered. The Boryslav-Pokuttya unit in the Ukrainian Carpathians is interpreted as a complex thrust system consisting of the five north-verging folded thrust sheets. The stratigraphic column of this zone includes the Upper Cretaceous deposits, but the Paleogene reservoirs contain almost 95% of the total recoverable hydrocarbons. These deep-marine deposits form the bodies of genetically related mass-flow and turbidity currents. A series of palinspastic maps interpreting the main depositional features was prepared to illustrate the distribution of main turbiditic systems. Traps in all fields are structural or combined structural-stratigraphic, dominated by faulted anticlines bounded by the detachments. Three major fields are described in detail as the classic Eastern Carpathian hydrocarbon accumulations with the long history of exploration and production.
Figures & Tables
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.
