The main target of the present study is determination of the properties of Upper Miocene reservoirs, that help us to predict the distribution and quality of these reservoirs. The study area is located in the northeastern part of the onshore Nile Delta, between Latitudes 31° 11' 00" and 31° 15' 00", and Longitudes 31° 50' 00", 31° 53' 00", and 31° 54' 00", where the total area is approximately 8.73 Km². The present study focuses on using the available geological information, well log and core data to evaluate the Upper Miocene Abu Madi sand bodies' reservoir, through the interpretation and integration of the electrical logs with core data, to find out the connections between the geological information and the well logging deductions. The results confirm that, the sandstone content exists as a main lithology in the Abu Madi Formation, at South Abu El Naga-2 and South Abu El Naga-9 wells. The best quality sandstone appears in the Upper Abu Madi section at South Abu El Naga-9 well (SAEN-9) and in the Lower Abu Madi section at South Abu El Naga-2 well (SAEN-2). The clastics in Abu Madi formation have good physical properties, in which the central part of the study area is the best area, as net pay and quality of Abu Madi reservoir and northeastern part is lowest quality.
