Abstract The Upper Miocene reservoir contributes to present challenge in their effective gas and production in onshore Nile Delta exploration, development & production, through recognition and understanding of the paleo-depositional environment distributions and sand reservoir delineation during the exploration and development phase. An inter-disciplinary workflow was followed in order to characterize the Upper Miocene reservoirs (Qawasim Formation). The workflow combined seismic elastic properties, core description, regional geological context, biostratigraphy, and petrophysical evaluation through the four wells of the study (EW-8, Luzi-2, Dabayaa-2, and Al-Hurani-1) inside West El-Manzala area, onshore, East Nile Delta. In a regional context, Upper Miocene reservoir was deposited post the sealevel DROP in the early Messenian. This sea-level DROP along with the Tortonian rotation led to creating a complex drainage system in the Early Messenian time. The incised valleys were primarily filled with fluvial dominated deposits then with fluvio-marine complex afterward then. These incisions were flooded by sea water in transgressive period |
