Geological and petrophysical research focused on reservoir properties of Upper Jurassic carbonate deposits was carried out in the central part of the Carpathian foreland, also taking into consideration facies development and diagenetic processes. Petrophysical analyses of porosity, permeability (intergranular and fracture), and capillary pressure measurement were conducted on samples from 28 boreholes. Types and ranges of permeability and porosity were correlated with diagenetic processes (such as karst phenomena) on the basis of extracted lithofacies and regional tectonics. The best petrophysical properties are connected with organogenic buildups of the Upper Jurassic rocks. High values of intergranular permeability only occur on this type of rocks. Dual porosity-fracture permeability and fractures dominate other rocks. The karst phenomena improved storage and filtration properties of rocks.

Deformation, Fluid Flow, and Reservoir Appraisal in Foreland Fold and Thrust Belts
Several topics are covered including: *the use of hydrocarbon-bearing fluid inclusions and apatite fission tracks as paleothermometers for reconstructing P-T evolution of subthrust reservoirs *the use of hydrocarbon-bearing fluid inclusions and apatite fission tracks as paleothermometers for reconstructing P-T evolution of subthrust reservoirs *the coupling of kinematic and thermal modeling performed to trace the burial (P-T) evolution of potential source rocks and reservoirs in three cases studies in the southern Apennines, Colombia, and Pakistan *analytical results and integrated studies, which link deformation and fluid circulation in various fold and thrust belts, with the Sierra Madre in Mexico, the Central Brooks Range, the Arctic in Alaska, the Coastal belt in northern Spain, and the Ukraine featured. Links between deformation, fluid flow, diagenesis, and reservoir characteristics are discussed in depth and descriptions of petrographic techniques integrated with basin modeling are discussed in case studies for carbonate reservoirs in the Apennines, the Canadian Rockies, and the Polish Carpathians, and for sandstone reservoirs in Eastern Venezuela. Sixteen of the twenty-one chapters illustrate the influence of thrust-belt evolution on regional petroleum systems. The petroleum potential in the Tunisian Atlas and in Sicily, close to where the Hedberg Conference and post-conference field trip were held, is described. An older example is documented, for the Gaspé Appalachians, where multiphase Paleozoic deformation had a strong control on the burial history of potential source rocks, petroleum generation and migration, and oil charge of the traps. As the first in the brand-new Hedberg Series of publications, this volume is a comprehensive look at understanding petroleum systems in fold and thrust belts.
