Summary: The Nile Delta region in Egypt is the main province for gas production, with Late Miocene sediments being the target for drilling. A study on the Messinian Qawasim Formation at El Tamad Field revealed two main facies: clastic and carbonate, with the sandstones showing excellent reservoir potential for hydrocarbons due to their depositional and diagenetic features. The microfacies of the sandstones exhibit characteristics such as well sorting, open packing, poor cementation, and enhanced porosity from diagenetic processes like dolomitization and grain cracking.

Summary: This study conducted a comprehensive geochemical assessment of Oligocene-Pliocene source rocks in the onshore part of the Nile Delta Basin. The results showed fair to good organic richness with gas-prone kerogen types. The organic matter was deposited under suboxic to anoxic nearshore marine or lacustrine settings with contributions from various sources. The pre-Miocene source rocks were suggested as the most probable candidates for hydrocarbons in the area.

Summary: The Upper Messinian Abu Madi Formation in the Nile Delta is a result of sediment deposition during the final stage of the Messinian salinity crisis. The presence of soft-sediment deformation structures (SSDS) suggests the role of earthquakes in causing liquefaction processes and deformation. Pressure disequilibrium is observed throughout the Abu Madi Formation, indicating the influence of seismic activity. The heterolithic nature of the sediments and lack of bioturbation contribute to the preservation of seismically induced deformation.

Summary: This study investigates the sedimentological analysis and petrophysical properties of the Messinian Abu Madi reservoir in the offshore Nile Delta Basin, aiming to determine how facies heterogeneities control reservoir quality. The study combines core data and wireline logs to identify different clastic facies and their petrophysical characteristics. The results show that the reservoir quality is strongly influenced by the original composition and primary depositional facies, with the best reservoir quality occurring in massive sandstones. The study also reveals the high potential of Abu Madi sandstones as gas-bearing reservoirs in the offshore Nile Delta Basin.

Summary: The Messinian incised-valley fill sediments of the Abu Madi Formation are the most prospective hydrocarbon-bearing reservoirs in the Nile Delta, where an integrated seismic-stratigraphic, sedimentological and petrophysical approach is applied to identify factors controlling reservoir heterogeneity. The study interprets two separate channelized systems reflecting flow dynamics and depositional energy variations, highlighting the impact of sedimentological and compositional controls on pore-scale heterogeneity and reservoir quality. Different reservoir rock types with varying lithological and compositional characteristics were identified, each displaying different petrophysical flow properties.

Summary: The objective of this study was to evaluate the petrography and petrophysical properties of the shallow marine clastic reservoirs in the Central Gulf of Suez Basin. The Matulla and Wata reservoirs exhibit good porosity and pore connectivity, with the presence of secondary porosity from feldspar dissolution. However, diagenetic processes such as quartz overgrowth and cementation have affected the porosity. The wireline logs and gas chromatography data support the presence of oil in the reservoirs.

Summary: This study assesses the reservoir properties of incised-valley sandstones in the Nile Delta Basin gas fields. The findings show that extensional faults played a significant role in the deposition of the sandstones, and the northernmost portion of the study area exhibits the most promising location for gas exploitation. The sandstones exhibit a fining upward trend with a relatively clean composition, and petrophysical investigations indicate favorable reservoir conditions. The presence of well-connected channels within the estuarine sandstones enhances reservoir productivity.

Summary: This study evaluates the reservoir quality and rock type zonation in the Belayim Land Oil Field, Gulf of Suez, Egypt, using integrated petrographical analysis and petrophysical estimation. Four reservoir rock types and hydraulic flow units were identified, with RRT1 and RRT2 showing the best reservoir zones. Capillary pressure tests confirmed the pore structure characteristics of different reservoir rock types. The study's findings aligned with other zonation methods in terms of porosity-permeability relationships and reservoir quality index.

Summary: This study evaluates the reservoir quality of the Nubia Formation sandstone in southwest Sinai, Egypt using hydraulic flow units (HFU) and electrical flow units (EFU). The analysis shows that the sandstones are mainly quartz arenite and are affected by diagenetic processes. Parameters for discriminating HFUs include permeability and porosity relationship, while EFUs are differentiated based on the relationship between formation resistivity factor and porosity.

Summary: This study demonstrates the use of neural networks in predicting hydraulic flow units by integrating well logs, routine core data, and minerals analysis. The model built using an artificial neural network connects x-ray diffraction analysis data and electrofacies model results to assess clay occurrence in each hydraulic flow unit. By dividing the reservoir into different hydraulic flow units using cored well data, the impact of clay on reservoir permeability can be evaluated.

Summary: This study conducted a spatial assessment and mapping of flood hazards in the Sekondi-Takoradi Metropolis (STM) of Ghana using the Analytical Hierarchy Process (AHP) and geographical information system. The results indicate that about 12% of STM lands are in very high flood zones and 24% are in high flood zones. The lower portions of STM are identified as the most susceptible to inundation. These findings provide valuable insights for effective flood planning and prevention in STM.

Summary: The carbonatites from the Richat dome in Mauritania are unique and underdocumented geological features. This study provides insight into the mineralogy and petrogenesis of the carbonatites, revealing three identified types and their association with spinel-bearing peridotite. The geochemical characteristics of the Richat carbonatites are similar to other Cretaceous alkaline carbonatite occurrences in different regions, suggesting a common geological process. The reactivation of a deep pan-African lineament is considered a fundamental factor in the formation of the Richat carbonatites.

Summary: Twenty-one gastropod species have been identified in the Cenomanian deposits of Bellezma-Aures mountains, eastern Saharan Atlas, Algeria, with four of them recorded for the first time in the Batna mountains. These gastropods are mainly found in the 'Marnes de Smail' Formation, and their community changes may be attributed to minor sea-level fluctuations, sedimentation rate variations, and hydrodynamics. The paleobiogeographic distribution of these gastropod assemblages indicates a tethyan affinity and faunal exchange during that time interval.
