Assessment of the petrophysical properties and hydrocarbon potential of the Lower Miocene Nukhul Formation in the Abu Rudeis-Sidri Field, Gulf of Suez Basin, Egypt
Lower Miocene rift sediments of the Nukhul Formation are one of the prominent hydrocarbon producers in the Gulf of Suez basin. In this study, we focused on the oil producing Nukhul sandstones of the Abu Rudeis-Sidri Field, located in the east central Gulf of Suez. Nukhul Formation is characterized b...

Nukhul Formation is characterized by the prominent low amplitude seismic reflectors and represents the youngest identified reflector (Lower Miocene) in the study area. Petrophysical assessment was carried out using wireline logs to infer the reservoir characteristics. The Nukhul sandstone reservoir exhibits lower shale volume (< 0.1 dec dominantly), 0.07–0.16 dec total porosity and effective porosity up to 0.13 dec within the Nukhul sandstone interval. Bulk density-neutron porosity cross plot infers primarily sandstone matrix with the influence of carbonates, which characterizes the studied reservoir as calcareous sandstones. Spectral gamma ray data indicates montmorillonite as the principal clay phase along with minor kaolinite and illite. The calculated water saturation of the reservoir zone in the three productive wells ranges between 0.17 and 0.34 dec (i.e., the hydrocarbon saturation equals 0.66–0.87 dec). A small range of bulk volume of water (0.011–0.03 dec) indicates superior quality of the hydrocarbon-bearing sandstone intervals. Absence of productive sands in one of the studied wells, drilled in the hanging wall implied structural control on hydrocarbon accumulation in the study area. This study provides crucial insights regarding the quantitative petrophysical characteristics, reservoir quality distribution and hydrocarbon potential of the Lower Miocene Nukhul clastic reservoir.
Highlights
This study presents the quantitative petrophysical characterization of the Lower Miocene Nukhul sandstones.
The reservoir sandstones are calcareous in nature and consist of montmorillonite as the dominant clay phase.
Reservoir exhibits very high hydrocarbon saturation with high lateral variations in porosity and shale volume.</description><identifier>ISSN: 2363-8419</identifier><identifier>EISSN: 2363-8427</identifier><identifier>DOI: 10.1007/s40948-023-00572-w</identifier><language>eng</language><publisher>Cham: Springer International Publishing</publisher><subject>Bulk density ; Carbonates ; Clay ; Effective porosity ; Energy ; Engineering ; Environmental Science and Engineering ; Foundations ; Gamma rays ; Geoengineering ; Geophysics/Geodesy ; Geotechnical Engineering & Applied Earth Sciences ; Hanging walls ; Hydraulics ; Hydrocarbons ; Illite ; Illites ; Kaolinite ; Miocene ; Montmorillonite ; Montmorillonites ; Oil and gas exploration ; Oil exploration ; Porosity ; Reflectors ; Reservoirs ; Sandstone ; Saturation ; Sedimentary rocks ; Sediments ; Shale ; Shales</subject><ispartof>Geomechanics and geophysics for geo-energy and geo-resources., 2023-12, Vol.9 (1), Article 36</ispartof><rights>The Author(s) 2023</rights><rights>The Author(s) 2023.
