| Abstract | ||||
| Disouq area is located on the onshore western part of the Nile Delta (N.D.); which is one of the most important gas provinces, as its sedimentary succession hides high gas potentiality. The study area is divided into five fields that is: Disouq, Sidi Salem Southeast, South Sidi Ghazy, North Sidi Ghazy, and Northwest Sidi Ghazy. The main reservoir in Disouq field is Abu Madi Formation, a significant reservoir made up of Miocene rock. Through advanced petrophysical techniques and well logging data from specific wells like Disouq-1X, Disouq-2X, Disouq-1-3, Disouq-1-4, Disouq-1-5 and Disouq-1-6 in addition to core data of SSSE-1X well for calibration. Lithologically Abu Madi Formation is composed of sandstone, shale, limestone, and anhydrite layers. Lithology and reservoir deriving mechanisms of Abu Madi reservoir is determined by using the available well-log and pressure data to construct many types of cross plots to reveal the different conditions that control the behavior of fluids within Abu Madi Formation. The evaluation of the reservoir's potential is determined by integrating geological and petrophysical studies, revealing the Abu Madi reservoir's classification into two cycles: each of which represents one phase of reservoir development in the Disouq field tentatively related to Lower and Upper Abu Madi reservoirs. The lower reservoir boundary separates Lower Abu Madi sand from the underlying Qawasim Formation. The hydrocarbon potential is distributed through the higher part of the Upper Abu Madi reservoir in Disouq field. Results of petrophysical analysis are represented vertically in the form of Litho-saturation cross plots and horizontally as Iso-Parametric maps, (hydrocarbon, water saturation, effective porosity, clay volume, net pay thickness), aiding in locating optimal areas for hydrocarbon accumulation and understanding the basin's characteristics. | ||||
