    The following project presents geological and geophysical analysis of Miocene deposits in the Ropczyce area. The analysis was carried out using PetroMod 1D v.11 software (Schlumberger). Models were made based on laboratory, seismic and well-logging data from Carpathian foredeep. Thermal history and compaction models were made based on well-logging data from the Góra Ropczycka-1K well and correlated with calculated vitrinite reflectance. In the second part of the project, 1D modeling for synthetic well was designed within the analyzed region. The purpose of the modeling was to reconstruct processes that took place during the basin formation. It has been shown that the transformation of rocks is too low for the presence of high temperature gas, however, the porosity in the miocen sediments is still high and can be an effective reservoir rock.

    The study presents analysis of the Carboniferous-Permian petroleum system. The main emphasis was on the determination of structural and lithologic condition, which led to the accumulation of natural gas in petroleum traps. Most of the gas fields were formed in typical structural traps. The others are located in stratigraphic and structural- stratigraphic traps. Structural traps are related to seismic horizon Z1’ (corresponding to the base of Zechstein). Mapping of seismic horizon Z1’, in general, does not cause any difficulties in the shallower part of the basin, however precise determination of the extent line of porous, permeable Rotliegendes sandstones still encounters problems. This paper describes methodology of petroleum traps interpretation based on seismic cross-section and well data, along with models of the traps and their interpretation.
