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.

Abstract
The structural deformation and the petroleum system of the southern Apennines thrust belt (SATB) are studied along a regional cross section traversing the Monte Alpi–Tempa Rossa fields. The SATB is interpreted as a system of three major structural blocks incorporating the basement and the sediments up to the Apulian platform deposits beneath an allochthonous complex. The Thrustpack® software has been used to reconstruct the successive geometries and their progressive burial under foredeep sediments and the allochthonous complex. The bottom of the Apulian platform and the basement are involved in the deformation, and the thickness of the Permian interval, drilled in the foreland, is extended regionally. The timing of the deformation is constrained by the ages of the Pliocene foredeep sediments drilled on top of the Apulian platform. This record was also instrumental to propose a flexure scenario of the migrating foredeep-forebulge system, in which the slope of the topography had to be maintained to a realistic value. These assumptions and boundary conditions were tested by successive, two-dimensional kinematic and thermal reconstructions until a satisfactory match could be obtained with the available temperatures and vitrinite reflectance data. A final good thermal calibration has been obtained for the structural blocks of Monte Alpi and Tempa Rossa. However, the relatively poor quality of the temperature and vitrinite data available for the most hinterland structure questions the conclusions about the validity of our proposed geometry and assumed accumulated thrust displacement. The methodology used in this work is a useful tool in exploration, because it forces one to improve and update structural scenarios and to provide the grounds for highlighting important data gathering to further enhance an evaluation of the hydrocarbon potential at a basin scale. This latter point will be described in a companion chapter.
