Summary: Within the last three decades, Pakistan has experienced twelve major earthquakes, resulting in significant loss of life and billions of dollars in economic damage. Despite the general understanding of seismic hazards in various parts of the country, densely populated cities like Attock still require a detailed vulnerability analysis to mitigate the impact of a major earthquake. This study integrates seismic hazard assessment schemes to evaluate the vulnerability of Attock city and highlights the inconsistency between current building designs and the expected seismic response and soil amplification, emphasizing the need for pre-disaster mitigation strategies.

Summary: The Miocene Salif Formation in the southern Red Sea of Yemen is a promising oil-source rock with high organic carbon content and oil saturation. Integrating geochemical data and geological information, the 1-D modeling suggests that the Salif source rock system is within the late oil-generation window. The models also demonstrate the conversion of kerogen to oil and limited oil expulsion since the Pleistocene, indicating the potential for oil production in suitable reservoir conditions.

Summary: Organic-rich shale samples from the Late Cretaceous Mukalla Formation in eastern Yemen were analyzed to evaluate their organic matter characteristics and gas generation potential. The samples contained high organic matter content and predominantly consisted of hydrogen-poor Type III kerogen, indicating good gas generation potential. Microscopic examination and biomarker measurements confirmed the land-derived organic matter origin in a fluvial deltaic environment under highly oxic conditions. The basin modeling simulations showed that a significant portion of the kerogen has been transformed into gas in the late Miocene until the present-day, suggesting substantial gas exploration potential in the deeper structural units of the Qamar-Jiza Basin.

Summary: This study analyzes the physical and geochemical characteristics of crude oil samples from the Melut Basin in southern Sudan to investigate the source rock properties and depositional environment. The results indicate that most of the oils are not biodegraded, except for one sample. The oils were generated from clay-rich source rocks and deposited in a lacustrine setting. The biomarker maturity and environmental indicators suggest that the Al-Gayger and Galhak formations contributed to these oil samples.

Summary: This study focuses on the litho- and microfacies of the Upper Cretaceous-Miocene sequence in West Esh El Mallaha area, Egypt, with an emphasis on carbonate rocks. The main objective is to understand the impact of facies and diagenetic processes on the storage capacity of the sequence. The studied sequence includes various formations deposited in shallow marine, lagoonal outer ramp, and high energy/open marine environments. Diagenetic processes such as neomorphism, calcite cementation, silicification, compaction, clay mineral alteration, dissolution, fracturing, and dolomitization have been identified. The storage capacity of the rock units is primarily affected by multiple cementation phases, but fracturing, dissolution, and dolomitization enhance the storage capacity.
