Summary: Despite advancements in computer methods for analyzing geological data, inadequate understanding of structural geology and improper use of geostatistics and geomechanics computer modeling can still lead to unexpected failures in engineering projects. Proper sub-division of project sites into realistic geological entities and a rigorous geological domaining technique are crucial in improving project-specific geological risk assessment and geomechanical parameter selection for design.

Summary: Drilling-induced fractures (DIFs) play a crucial role in understanding in-situ stresses and variations in stress orientation. They are important for sand production prediction, wellbore stability, fluid circulation, and fracture propagation induced by hydraulic treatments. Distinguishing DIFs from natural fractures is essential for identifying damage zones and modeling fracture networks.

Summary: This article discusses the deformation of planetary bodies, pointing out that Earth is the only planetary body in the solar system that is related to plate tectonics, and the deformation mechanisms of other planetary bodies are yet to be studied. The article mentions that technological advancements and the improvement in planetary space mission data provide an opportunity to study planetary surface deformation, while also highlighting the lack of micro-to-local scale information in planetary structural geology studies. Finally, the article suggests that studying old deformed surfaces of Mercury, the Moon, and Mars can deepen our understanding of the early evolution of Earth tectonics.

Summary: The study on the Mauddud reservoir of the Sabiriyah field in Kuwait reveals that reservoir complexity and permeability heterogeneity are caused by the interplay between sedimentology, diagenesis, and structural evolution. A multidisciplinary approach identified the geological processes responsible for the development of high-permeability elements in the reservoir. Integrated evaluation of static and dynamic information established the 3D distribution of these elements and their impact on reservoir properties.

Summary: This paper investigates the upper limit of ejector performance by constructing an ideal ejector and thermodynamically optimizing its working process to achieve minimal entropy generation. The analytical solutions for optimal mixing pressure and maximal entrainment ratio are deduced for ideal gas working conditions. The thermodynamic upper limits provided in this study offer a more reasonable benchmark for evaluating ejector performance compared to previous models.

Summary: This paper introduces a general hierarchical ensemble-learning framework (ELF) for reliability analysis, which consists of two-layer models and three different phases. A novel method called CESM-ELF is proposed by embedding the classical ensemble of surrogate models (CESM) in the proposed ELF. The research results show that CESM-ELF outperforms CESM in prediction accuracy and is more efficient.

Summary: The project aimed to characterize the engineering properties of Mangking Sandstone Formation in Maran, Pahang, using geological and geomechanical techniques. The RMR system was applied to assess the rock mass quality, with values ranging from 73 to 78, placing the Mangking Sandstone in Class II (good rock). The SMR system was used to evaluate the slope stability, placing the rock slope of Mangking Sandstone in Maran area in Class II (stable slope).
