摘要

本研究调查了阿布-罗阿什 F 组元(AR/F)的地球物理特性,该组元是位于阿布-加拉迪格盆地(埃及)东部地区希巴油田的一个潜在非常规油藏。对地震数据的分析表明,在整个研究区域内,存在 ENE-WSW 向反斜坡褶皱和 NW-SE 及 WNW-ESE 向延伸断层,这证明了晚白垩世右旋扳动构造活动的影响。这种构造体系被认为对 AR/F 碳酸盐岩内部微裂缝的形成起到了重要作用,而微裂缝可以通过提高渗透率和孔隙度来增强储层的潜力。岩石物理评估确定了多口井特定深度区间内的有利储层带。这些区域显示出良好的储层质量,其特点是页岩体积小(低于 0.20),这表明储层岩石较清洁,粘土含量较少。此外,较高的总孔隙度(0.20 至 0.25)和适中的有效孔隙度(0.15 至 0.20)表明,岩石的大部分孔隙空间可用于储存碳氢化合物。低水饱和度(介于 0.40 和 0.50 之间)进一步证实了碳氢化合物的存在,因为它表明孔隙中主要不是水。此外,高碳氢饱和度(介于 0.50 至 0.60 之间)证实储层中存在大量碳氢化合物。对所有分析井的这些岩石物理特性进行的定量评估进一步证实了 AR/F 油气层良好的储层质量和潜力。地震和岩石物理数据的整合提供了对储层特征的全面了解,突出表明 AR/F 成员是 Abu Gharadig 盆地东部边界,尤其是 Heba 油田的一个重要油藏。这项研究的结果补充了对该地区含油层的现有认识,表明 AR/F 成员可能是该盆地油气资源的宝贵补充。研究结果强调了进一步勘探和开发 AR/F 成员的重要性,以充分发挥其作为该地区石油生产主要贡献者的潜力。

Geophysical evaluation and petrophysical assessment of the Abu Roash "F" Member: A probable unconventional oil reservoir in Heba Field, eastern Abu Gharadig Basin, Egypt

This study investigates the geophysical properties of the Abu Roash F Member (AR/F) as a potential unconventional oil reservoir in Heba Field, located in the eastern region of the Abu Gharadig Basin (Egypt). Analysis of seismic data reveals the influence of Late Cretaceous dextral wrenching tectonic activity, evidenced by the presence of ENE-WSW anticlinal folds and intersecting NW-SE as well as WNW-ESE extensional faults throughout the study area. This tectonic regime is believed to have played a significant role in the formation of micro-fractures within the AR/F carbonate, which can enhance the reservoir's potential by improving its permeability and porosity. Petrophysical assessment identifies favorable reservoir zones within specific depth intervals across multiple wells. These zones exhibit promising reservoir quality, characterized by low shale volume (below 0.20), which indicates a cleaner reservoir rock with less clay content. Additionally, the high total porosity (ranging from 0.20 to 0.25) and moderate effective porosity (ranging from 0.15 to 0.20) suggest that a substantial portion of the rock's pore space is available for storing hydrocarbons. The low water saturation (between 0.40 and 0.50) further supports the presence of hydrocarbons, as it indicates that the pores are not predominantly filled with water. Furthermore, the high hydrocarbon saturation (ranging from 0.50 to 0.60) confirms the significant presence of hydrocarbons within the reservoir. The quantitative assessment of these petrophysical properties across all analyzed wells further confirms the good reservoir quality and potential of the AR/F Member. The integration of seismic and petrophysical data provides a comprehensive understanding of the reservoir characteristics, highlighting the AR/F Member as a significant oil reservoir in the eastern border of the Abu Gharadig Basin, particularly in Heba Field. This study's findings complement the existing knowledge of oil-bearing formations in the region, suggesting that the AR/F Member could be a valuable addition to the basin's hydrocarbon resources. The results underscore the importance of further exploration and development of the AR/F Member to fully realize its potential as a major contributor to the area's oil production.

期刊介绍: The Journal of African Earth Sciences sees itself as the prime geological journal for all aspects of the Earth Sciences about the African plate. Papers dealing with peripheral areas are welcome if they demonstrate a tight link with Africa. The Journal publishes high quality, peer-reviewed scientific papers. It is devoted primarily to research papers but short communications relating to new developments of broad interest, reviews and book reviews will also be considered. Papers must have international appeal and should present work of more regional than local significance and dealing with well identified and justified scientific questions. Specialised technical papers, analytical or exploration reports must be avoided. Papers on applied geology should preferably be linked to such core disciplines and must be addressed to a more general geoscientific audience.
