The Alam El Bueib 3C Field is located in the eastern part of the Dahab-Mireir sedimentary basin in the north Western Desert of Egypt. The Lower Cretaceous Alam El Bueib Sandstone reservoir is a potentially producing reservoir in the field. Lithostratigraphic correlation and ditch cutting description have helped in stratigraphically locating the potential sandstone reservoirs within the basal part of Alam El Bueib 3A Bed and locally dividing it into three potential separate reservoirs. Qualitative analysis of borehole depth imaging logs helped in revealing the stratigraphic trap style of Basal Alam El Bueib sandstone reservoirs and detection of deposition paleoenvironment as a shallow marine environment of wave-dominated estuary channelized system. Structural seismic interpretation for available Pre-Stack-Depth-Migrated 3D seismic data has revealed that AEB 3C Field structure is a four-way dip anticlinal closure that trends north east-south west. A better understanding of the geological nature of the Alam El Bueib 3A sandstone reservoirs combined with the structural-stratigraphic trap style has led to a lower risk exploratory/development plan for Alam El Bueib potential sandstone reservoirs in the Alam El Bueib 3C field. Borehole depth imaging analysis results, integrated with seismic structural interpretation maps and information from conventional electrical well logs, represented a high-quality workflow that showed remarkable efficiency in a better understanding of reservoir distribution in the case of present heterogeneous Alam El Bueib sandstone reservoirs and providing the optimum solution for similar geological conditions in other areas.

将钻孔深度成像和地震反射结果整合到储层圈定中:以埃及北部西部沙漠 Alam El Bueib 3C 油田为例

Alam El Bueib 3C 油田位于埃及西北部沙漠的 Dahab-Mireir 沉积盆地东部。的下白垩Alam的埃尔Bueib砂岩储层是该领域的潜在生产储器。岩性地层对比和沟渠切割描述有助于在地层上定位 Alam El Bueib 3A 床层底部的潜在砂岩储层,并将其局部划分为三个潜在的独立储层。钻孔深度成像测井的定性分析有助于揭示 Basal Alam El Bueib 砂岩储层的地层圈闭类型,并有助于检测沉积古环境作为波浪主导的河口渠道化系统的浅海海洋环境。结构的地震解释可用的叠前深度迁移 3D 地震数据显示 AEB 3C 场结构是一个四向倾斜的背斜闭合,趋势为东北-西南。更好地了解 Alam El Bueib 3A 砂岩储层的地质性质,结合构造地层圈闭样式,已导致对 Alam El Bueib 3C 油田中 Alam El Bueib 潜在砂岩储层的风险较低的勘探/开发计划。钻孔深度成像分析结果,结合地震构造解释图和常规电测井信息,
