In this work, the petrophysical properties of Abu Madi reservoir in El-Qara Field at northern Nile Delta Basin (NDB) were evaluated depending on well logging data of two wells: El-Qara-2 and El-Qara-3. This evaluation revealed that in El-Qara-2 well, the promising gas zone is detected between depths of 3315 and 3358 m, while in El-Qara-3 well, the best gas interval is detected between depths of 3358 and 3371 m. In addition to the production test parameters (gas rate, condensate rate, gas gravity, condensate gravity, gas-to-oil ratio, flowing tubing head pressure, flowing bottom hole pressure, and static bottom hole pressure), the calculated petrophysical parameters (shale volume, total porosity, effective porosity, and water saturation) for both intervals were relatively similar. This confirms that the investigated wells were drilled at the same reservoir interval within Abu Madi Fm. The depth variation in the examined zones was attributed to the presence of buried normal faults between El-Qara-2 and El-Qara-3 wells. This observation may be supported from the tectonic influence during the deposition of Abu Madi Fm. as a portion of the Messinian syn-rift megasequence beneath the NDB.

在这项工作中，根据两口井的测井数据评估了位于尼罗河三角洲盆地 (NDB) 北部 El-Qara 油田的 Abu Madi 油藏的岩石物理性质：El-Qara-2 和 El-Qara-3。评价结果显示，El-Qara-2井在3315～3358m深度之间检测到有前景的气层，而El-Qara-3井在3358～3371m深度之间检测到最佳气层。除了生产测试参数（气速、凝析油率、气体比重、凝析油比重、气油比、流动油管头压力、流动井底压力和静态井底压力）外，计算的岩石物理参数（页岩）体积、总孔隙度、有效孔隙度和含水饱和度）相对相似。这证实了所研究的井是在 Abu Madi Fm 内的相同储层间隔中钻探的。检查区域的深度变化归因于 El-Qara-2 和 El-Qara-3 井之间存在埋藏的正断层。Abu Madi Fm 沉积期间的构造影响可能支持这一观察结果。作为 NDB 下墨西拿同裂谷大序列的一部分。
