“…The Thermal boundary condition assessment for the October oil field (NO124-1 well) including the palaeo water depth (PWD, in meter), the synthesized sediment-water interface temperature (SWIT, in C), and the palaeo-heat flow (HF, in mW/m2) specified for each geologic event using the tectonic framework and crustal evolution of the Gulf of Suez, Egypt [Colour figure can be viewed at wileyonlinelibrary.com] is considered the main cause of a higher heat flow rate (Awadalla, Hegab, Ahmed, & Hassan, 2018).…”

“…Alternatively, the sedimentation rate in the syn-rift represented high sedimentation and rapid subsidence than the pre-rift one. Finally, the subsidence of the early post-rift, which occurred through the Middle-Late Miocene is characterized by a slow to moderate rate because of relative tectonic quiet on the whole Red Sea rift system (Awadalla et al, 2018). During the burial history, the source rock is suffering from increasing temperatures.…”

Geochemical studies were applied to evaluate the possible source rocks of Cretaceous-Eocene formations in the October oil field, including pyrolysis analysis data such as total organic carbon (TOC %), generating source potential (S2), production index (PI), oxygen, and hydrogen indices (OI, HI) and (Tmax). Three source rocks are characterized by fair to good and very good TOC%, which are Thebes, Duwi, and Abu Qada formations with kerogen type I and type II, respectively, and some samples are in the type III region reflecting the degree of maturation and can generate oil and gas. 1D basin models were constructed for five wells to simulate the multi-tectonic phases and multiple burial histories, migration path, and event chart in the study area. The sedimentation rates from Cretaceous to Palaeocene age are characterized by low burial rate sedimentation, low to medium in the Eocene age, and high burial rate and rapid sedimentation in the Miocene and post-Miocene age. The petroleum system of the October oil field was studied, and two petroleum systems can be recognized, according to the integration studies between the source rock evaluation and petroleum basin modelling.

To predict distribution of diagenetic stages of Xihu Sag Huagang Formation sandstone reservoir and secondary pore development zone, and research original pore reservation and secondary pore increase and decrease in reservoir evolution process, combining traditional diagenesis research and numerical simulation technique, and based on interaction model and effect model, this paper establishes a aggregative model on numerical simulation of diagenetic stages. In diagenesis simulation process, based on process response principle, and restricted by current diagenetic stage distribution and type, diagenetic stage distribution and type of reservoir during geological historical evolution period is back stripped through diagenetic temperature. Taking single well diagenetic stage data as constraint condition, and combining with research area burial history, ground temperature history, and diagenetic stage division basis, and scheme, plane distribution of diagenetic stages of the whole research area during each geological historical period is finally obtained.

Burial history and thermal evolution of the field was inferred by Awadalla et al (2018). Organic-rich pre-Miocene Thebes Formation is the prominent source rock in the Abu Rudeis-Sidri field (Mostafa and Ganz 1990;Mostafa et al 1993;Awadalla et al 2022).…”

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.
