Summary:
The investigated lithological profiles were subdivided into three lithofacies: sandstone, mudstone and shale. Every subdivision was assigned different compaction curve which corresponds to the suitable porosity - depth relation. Moreover, due to intensive Neogene thrusting and faulting movements, the profiles were divided into tectonic zones. Core data and dipmeter measurements helped to distinguish particular deformation events. Earlier studies have highlighted the separate, different from each other NTCL for single tectonic zone. Pore pressure/effective stress impact on sediments pore space were also noted. The result of these works is detailed pore pressure profiles within the study area and identification of top of overpressured zone which is confirmed by well tests.
