10 REGIONAL STRUCTURAL-PARAMETRIC 3D MODEL OF THE SZCZECIN TROUGH – DATA INTEGRATION, METHODOLOGY AND LIMITATIONS ABSTRACT: A regional structural-parametric 3D model of the Szczecin Trough (NW Poland), covering more than 12,500 km², was constructed using the Corner Point Grid approach. The model integrates 346 wells, 2D seismic data in both time and depth domains, interpreted struc- tural horizons, and legacy regional models. The final grid consists of approximately 1.54 bil- lion cells with a uniform lateral resolution of 100 × 100 m and includes ten stratigraphic se- quences from the Cenozoic to the Zechstein. Shale volume (Vsh) was modeled using Ordinary Kriging and Sequential Gaussian Simulation (10 realizations), allowing assessment of deter- ministic and stochastic approaches at the regional scale. The study discusses key methodologi- cal challenges related to data integration, structural simplifications, computational constraints, and uncertainty associated with uneven spatial data coverage. The resulting model provides a consistent regional framework for further geothermal, CO₂ storage, and petrophysical anal- yses.
