Forward Stratigraphic Modeling of a Restored Cross Section from Apulia to Gavrovo

Abstract

Summary Building a coherent model, consistent with different events and processes over a long geological time frame is not an easy task. In this case study, The challenge was to model a 400 km long restored section in the Ionian zone (NW Greece), reproducing the main observations at wells and the key features seen on seismic and wells, in a single and reliable model of evolution of a Thethysian margin over more than two hundreds and fifty millions years. Furthermore, once the global conditions and the sedimentary dynamics of the evolution of this Passive Margin were defined by Forward Stratigraphic and Structural Modeling, a set of computation of Marine Organic Parameters was launched to address the main characteristics of the Source Rocks, improving the constrains on the Petroleum System. This large-scale integrated study brings notable and valuable information on the architecture of all the elements of the Petroleum System, from depositional conditions of Organic Rich layers to Reservoir size, continuity, connectivity, quality and EOD, and Seals thickness and efficiency. Finally, the Marine Organic Matter simulation helped to identify and characterize possible relevant Source Rocks layers.
