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

Abstract Lower Miocene rift sediments of the Nukhul Formation are one prominent hydrocarbon producers in Gulf Suez basin. In this study, we focused on oil producing sandstones Abu Rudeis-Sidri Field, located east central Suez. is characterized by low amplitude seismic reflectors and represents youngest identified reflector (Lower Miocene) study area. Petrophysical assessment was carried out using wireline logs to infer reservoir characteristics. The sandstone exhibits lower shale volume (< 0.1 dec dominantly), 0.07–0.16 total porosity effective up 0.13 within interval. Bulk density-neutron cross plot infers primarily matrix with influence carbonates, which characterizes studied as calcareous sandstones. Spectral gamma ray data indicates montmorillonite principal clay phase along minor kaolinite illite. calculated water saturation zone three productive wells ranges between 0.17 0.34 (i.e., equals 0.66–0.87 dec). A small range bulk (0.011–0.03 dec) superior quality hydrocarbon-bearing intervals. Absence sands wells, drilled hanging wall implied structural control accumulation This provides crucial insights regarding quantitative petrophysical characteristics, distribution potential clastic reservoir.
