“…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). A stratigraphic chart is presented in (Fig.…”

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.

“…The available interpreted seismic sections and well data in the area under study were collected from different published sources [e.g. Mokhles et al, 2003;Zahra et al, 2015Zahra et al, , 2016. Sixteen seismic sections were obtained covering the northern, central and southern parts of the study area in addition to a single geologic cross section for the southeastern part of the area.…”

The present study aims to identify promising oil and gas bearing objects in the eastern part of the Gulf of Suez. Three-dimensional (3D) modelling of the study area using Petrel software was carried out. The basement layer was created using airborne magnetic data through 3D modelling using GM-SYS-3D software. The sedimentary succession was generated using interpreted seismic sections and well data, and then the data was localised and digitised using Petrel software to be used in the building of the model. The lithology and age of each layer were accurately determined to be used in building the petroleum system model. Data about the temperature gradient and thermal conductivity were obtained for different wells along the Gulf of Suez and the eastern shoulder of the Gulf. In addition to that, heat flow values of the study area have been computed and the heat flow map was created to be used in predicting oil and gas accumulation in the study area. Information about hydrocarbon masses and volumes generated and expelled from the source rocks as well as the amount that has migrated and accumulated in reservoirs were computed through running forward simulation using PetroMod software. Accumulations of oil and gas are modelled in the different reservoir layers in the study area. New accumulations of oil and gas were generated within the study area; these accumulations have not been discovered yet. The study area needs more detailed 2D and 3D investigation in the predicted promising locations, where the probability of the existence of hydrocarbon is high. In the southeastern part of the area no activity has been done and according to the results of the petroleum system model, hydrocarbon accumulation area could be discovered in this area in different reservoirs.

This research focuses on the structural study of three folded horizons of Fat'ha, Jeribe, and the Euphrates in Judaida structure, Northern Iraq. Depth contour maps for three horizons using the time and velocity data called from seismic surveys. Seismic interpretation suggests that Judaida structure is a positively inverted structure. It is an anticline on the level of Tertiary and the top and an extensional structure on the level of pre-Tertiary sequence. Judaida structure is an asymmetrical longitudinal anticline; its Northeastern limb is steeper than its Southwestern limb. The axis of the anticline and the major normal faults are both trending toward the Northwest. The normal fault picked influencing only the pre-Late Cretaceous sequence where is the folding affected the whole sequence; of the extension forces, it affected the region during that period. Late Pliocene compressions resulted in folding and reverse faulting of the whole sequence and inversion of movement along the pre-existing normal faults. The resulted faults are called inverted faults.
