This study utilizes well logs dataset and 2D seismic from Port Fouad marine (PFM) ‎Field to investigate reservoir lithofacies, rock-types as well as the associated gas ‎chimneys, pockmarks, bright anomalies of escaping fluids in the seafloor, and high-‎faulted zones caused by the chimney’s developments. petrophysical analyses revealed ‎that the Upper Miocene Wakar Formation hosts scattered, thin gas pay zones (<10m) ‎with low hydrocarbon saturation values, high water saturation, and high shale volume. ‎These poor reservoir characteristics prevented accumulation of thick gas zones, ‎thereby several gas escape features (e. vertical chimneys) are observed in the region. ‎The 3D structural model reveals the presence of four major normal faults (F1, F2, F3, ‎and F4) oriented NW-SE and WNW-ESE, creating grabens and half grabens. These ‎major faults are directly related to the inverted tectonics during the Cretaceous-‎Paleogene compression (Syrian Arc phase). A link between these structural patterns ‎and gas escape zones is proposed, and the absence of good reservoir facies likely ‎promoted an active phase of gas seepage in the study region. In addition, such gas ‎escape chimneys can create catastrophic events on the seafloor and are considered ‎direct evidence for the presence of gas generation and failure in accumulation.‎
