摘要

The West Delta Deep Marine (WDDM) concession is among the most prolific hydrocarbon regions in the Mediterranean Sea. Its formation and evolution were shaped by a series of tectonic events spanning from the Pre-Cretaceous to the Early Pliocene. Accordingly, this study aims to enhance the understanding of the structural elements and tectonic fabrics that have contributed to the development of these features. Tectonic evolution started with Early Mesozoic rifting linked to Neotethys opening and Afro-Arabian–Eurasian plate divergence, forming the Rosetta Fault, an extensional feature with variable seismic displacement. Miocene compression from African–Eurasian convergence produced the Nile Delta Offshore Anticline (NDOA).Tectonic phases formed a positive inversion structure influencing the Herodotus Basin. Combined with deep submarine channel morphology, they control sedimentation, hydrocarbon trapping, and migration. This study also aims to reconstruct subsurface geometries and evaluate Abu Madi Reservoir quality through the integration of high-resolution 2D seismic reflection data, well log analysis, and 3D structural modeling. The 3D static reservoir model reveals significant heterogeneity and net pay thicknesses within the Abu Madi Formation, suggesting high-quality reservoir zones associated with Messinian-age carbonates, evaporites, and clastic sequences. These findings contribute to a more refined understanding of hydrocarbon migration pathways and accumulation mechanisms in the Herodotus Basin and adjacent areas, with implications for future exploration strategies.
