摘要

This study focuses on the Neogene-Quaternary subsurface sedimentary succession of the Kamose field, Offshore North Sinai Concession, Egypt, to discover new natural gas resources by integrating all the available seismic data that was processed and analyzed using the PETREL software, with the available well-logging data from the A-1 well at the Kamose field, to evaluate reservoir potential. The seismic interpretation divided the investigated succession into two Mega-sequences: the Pre-Messinian and Post-Messinian mega-sequences, with the targeted reservoir intervals belonging to the Post-Messinian sequence. Several structural features are identified, including Growth faults, listric faults, roll-over fold and salt diapir, with a dominant NW–SE structural trend.

The detailed petrophysical analysis of the A-l well logs data revealed two sandstone intervals interpreted as gas-bearing zones. The quantitative petrophysical evaluation indicates favorable reservoir properties, characterized by low shale volume (23–29%), high total porosity (36–38%), high effective porosity (30–31%), low water saturation (23–42%), and low bulk volume of water (0.07–0.12). The direct hydrocarbon indicator technique (DHI) highlights one of these intervals (zone-1) as a prominent bright spot, attributed to its considerable thickness of approximately 74 m.

Furthermore, the comparative analysis between the newly delineated seismic bright spots and those encountered in the drilled A-1 well suggests a significantly high probability of successful gas prospect identification within the Pliocene–Pleistocene interval of the North Sinai Concession. Overall, this study applies an integrated seismic–petrophysical workflow on post-Messinian reservoirs in the Kamose Field, providing new insights into the gas potential of Pliocene sandstones offshore the Nile Delta, supporting future development planning.
