Characterization of reservoir petrophysical properties provides critical insights into reservoir deliverability and field development strategy. The main objective of this work is to present a comprehensive core-based petrophysical assessment of the Cenomanian Bahariya Formation and the Turonian Abu Roash (AR-D and AR-E, respectively) Members of the Abu Gharadig field situated in the Western Desert, Egypt. The AR-D is water-wet and consists of micro- to mesoporous shallow marine limestone lithofacies with moderate porosity (Φ), poor horizontal permeability (Kh) with poor permeability anisotropy due to the presence of vertical fractures, while the nano- to mesoporous argillaceous limestone lithofacies is very tight. Both the lithofacies exhibit primary and secondary depositional fabrics. Overall, the AR-D member exhibits impervious to poor reservoir quality, and so a suitable stimulation strategy will be essential to produce from this interval. The AR-E interval implies a tidal depositional environment. The calcareous sandstone lithofacies of the AR-E is macro- to megaporous and exhibits moderate to high porosity (> 15%) and excellent permeability (up to 305 mD). The meso- to microporous glauconitic siltstones of the AR-E have poor porosity and permeability. Both lithofacies are characterized by high water saturation, preserve primary depositional fabrics and consist of isotropic pore system along with some connected horizontal pores yielding higher permeability anisotropy. The Bahariya Formation consists of fine to medium grained massive sandstone lithofacies with minor siltstone intercalations, indicating a channel deposit in a coastal or fluvio–deltaic environment. It exhibits high porosity (~ 20%) and permeability (up to 649 mD) but shows very high water saturation. It preserves the primary depositional fabrics with isotropic pore system. The thin siltstone intercalations may act as vertical barriers. Based on the petrophysical assessment, we made recommendations on the reservoir development aspects.

储层岩石物理特性的表征为储层产能和油田开发策略提供了重要的见解。这项工作的主要目的是对位于埃及西部沙漠的 Abu Gharadig 油田的 Cenomanian Bahariya 组和 Turonian Abu Roash（分别为 AR-D 和 AR-E）成员进行基于岩心的综合岩石物理评估. AR-D 为亲水性，由微孔至中孔浅海相灰岩岩相组成，孔隙度适中（Φ），水平渗透率差（Kh) 由于存在垂直裂缝，渗透率各向异性较差，而纳米至中孔泥质灰岩岩相非常致密。两种岩相都表现出初级和次级沉积组构。总体而言，AR-D 段表现出不受储层质量差的影响，因此合适的增产策略对于从该层段进行生产至关重要。AR-E 区间暗示了潮汐沉积环境。AR-E 的钙质砂岩岩相为大孔至大孔，具有中至高孔隙度（> 15%）和优异的渗透率（高达 305 mD）。AR-E 的中孔至微孔海绿石粉砂岩孔隙度和渗透性较差。两种岩相均以高含水饱和度为特征，保留原生沉积组织，由各向同性孔隙系统和一些连通的水平孔隙组成，产生更高的渗透率各向异性。Bahariya 组由细到中等粒度的块状砂岩岩相组成，夹有少量粉砂岩，表明在沿海或河流三角洲环境中存在河道沉积。它表现出高孔隙度（~ 20%）和渗透率（高达 649 mD），但水饱和度非常高。它保留了具有各向同性孔隙系统的原始沉积组织。薄的粉砂岩夹层可以作为垂直屏障。基于岩石物理评估，我们提出了储层开发方面的建议。Bahariya 组由细到中等粒度的块状砂岩岩相组成，夹有少量粉砂岩，表明在沿海或河流三角洲环境中存在河道沉积。它表现出高孔隙度（~ 20%）和渗透率（高达 649 mD），但水饱和度非常高。它保留了具有各向同性孔隙系统的原始沉积组织。薄的粉砂岩夹层可以作为垂直屏障。基于岩石物理评估，我们提出了储层开发方面的建议。Bahariya 组由细到中等粒度的块状砂岩岩相组成，夹有少量粉砂岩，表明在沿海或河流三角洲环境中存在河道沉积。它表现出高孔隙度（~ 20%）和渗透率（高达 649 mD），但水饱和度非常高。它保留了具有各向同性孔隙系统的原始沉积组织。薄的粉砂岩夹层可以作为垂直屏障。基于岩石物理评估，我们提出了储层开发方面的建议。薄的粉砂岩夹层可以作为垂直屏障。基于岩石物理评估，我们提出了储层开发方面的建议。薄的粉砂岩夹层可以作为垂直屏障。基于岩石物理评估，我们提出了储层开发方面的建议。
