摘要：Abu Madi Formation is a gas fertile rock unit in Nile Delta basin and the main gas production rocks in Baltim fields which located in the Mediterranean sea, north of Baltim city, Egypt. This rock unit in the study area contains two gas productive sand zones; these are zone III main and zone III lower. The lithologic components of Abu Madi Formation that defined from the dia-porosity (density–neutron) cross-plot and the tri-porosity (RHOMAA–DTMAA) cross-plot, showing that, Abu Madi Formation consists mainly of sandstone, shale, shaly sandstone in some parts and calcareous material. The resultant petrophysical parameter values, revealed that, both zone III main and zone III lower in the area under investigation show potential in their petrophysical characteristics, as a fertile gas reservoir. Zone III lower shows the most advanced petrophysical characterisation as a desired reservoir, with lower value of shale volume of 4%, good effective porosity of 17% and higher value of hydrocarbon saturation of 70%. Finally, these reservoirs are bounded by two normal faults with remarkable displacement. The first fault located at south, strike E - W and dips toward the North, the other fault located north, trending NE- SW and dips to the north.
