Purpose. The research is aimed at evaluating the petrophysical characteristics of the Late Cretaceous Matulla Formation in the central part of the Gulf of Suez in order to detect its hydrocarbon reservoir potential. Methods. Well logs from five wells (Muzhil-1, -2, -4, -7, -8) were used to evaluate the Matulla reservoirs based on a computerized approach. Petrophysical parameters and fluid types were calculated, verified using core data, and represented vertically as lithosaturation cross plots and laterally as isoparametric variation maps.. Findings. Evaluation of total porosity (Φt), effective porosity (Φe), shale content (Vsh), water saturation (Sw), permeability (K), bulk volume of water (BVW), and net pay characteristics of Matulla Formation in the Muzhil wells showed the following weighted average values: 18-23%, 15-19%, 21-40%, 20-100%, 1.1-281 mD, 3-21% and 0-83 ft, respectively. The Log-derived lithology identification indicates that the major matrix component of the Matulla Formation is quartzose sandstone with minor shale and carbonate contents. The upper zone is a poor reservoir, while the middle and lower zones are considered good reservoirs in all studied wells. It is expected that Muzhil-2 will produce oil without water; however, Muzhil-1 and Muzhil-4 will produce oil with water; while Muzhil-7 and Muzhil-8 will produce water only. Originality. Detailed log-derived petrophysical evaluation, verified by core analysis and well tests (DST and MDT), construction of lithosaturation cross plots for each well and isoparametric petrophysical maps are performed for the first time for Matulla Formation in the Muzhil field. Practical implications. The obtained results on lithosaturation and petrophysics have expanded the knowledge about the characteristics of the Matulla Formation sediments, hosting promising reservoir intervals, and should be taken into account in future exploration and development of the Muzhil field.

“…The rifting of the Gulf of Suez started during the Lower Miocene due to the divergent movement between the African plate and the Arabian plate which created a series of NW-SE to NNW-SSE trending normal faults (Patton et al 1994;Omran 1995;Abul Karamat and Meshref 2002;Bosworth et al 2005). The faulted blocks of the Gulf of Suez are bounded mainly by NW normal faults and connected to each other by WNW-, NNE-and NE-oriented faults (Abd-Allah et al 2014). The syn-rift Miocene deposit in the Gulf of Suez province changes laterally from clastic sediments to more deeply buried sediments towards the rift axis (Bosworth and McClay 2001).…”

“…The syn-rift Miocene deposit in the Gulf of Suez province changes laterally from clastic sediments to more deeply buried sediments towards the rift axis (Bosworth and McClay 2001). Due to the tilt of the pre-rift blocks, the Miocene rocks overlying the different pre-rift units vary in lithologies and thicknesses (Abd-Allah et al 2014). The structure of Abu Rudeis-Sidri area is an asymmetrical NW-SE trending anticlinal feature separated by a number of NW-SE fault systems and formed during the late Oligocene-Early Miocene time (rifting phase) (Zahra and Nakhla 2016b).…”

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 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.

Nukhul Formation is one of the primary oil reservoirs in the Gulf of Suez Basin. Rabeh East is an oil producer field located at the southern border of the Gulf of Suez. The present work deals with the geophysical investigation of Nukhul Formation in Rabeh East field using seismic lines and well log data of four wells, namely RE-8, RE-22, RE-25 and Nageh-1. The interpreted seismic profiles display that the RE-8 Well is the only well drilled within the up-thrown side of a significant horst fault block bounded by two normal faults. However, the other wells penetrated the downthrown side. The qualitative interpretation of the well logging data for RE-8 Well delineated two intervals have good petrophysical parameters and ability to store and produce oil. These zones locate between depths 5411.5 and 5424 ft (zone I) and between 5451 and 5459.5 ft (zone II). The calculated petrophysical parameters for zone I display water saturation (22–44%), shale volume (10–23%), total porosity (18–23%), effective porosity (12–20%) and bulk volume of water (0.04–0.06). Zone II exhibits water saturation (13–45%), shale volume (10–30%), total porosity (18–24%), effective porosity (11–20%) and bulk volume of water (0.03–0.05). This analysis reflects excellent petrophysical characteristics for the sandstones of Nukhul Formation in Rabeh East oil field for producing oil if the wells drilled in a suitable structural closure.
