Summary: This study focused on the sedimentary rocks of the Lower Cretaceous in the Euphrates Graben area, using various techniques like core description, thin section observations, and electron microscopy. The research identified different types of dolomites in the Judea Formation, indicating a two-stage diagenetic history for the sediments, which led to improved reservoir properties by enhancing porosity.

Summary: The dissolution dynamics of carbonate rocks in shallow burial are important for the formation of high-quality reservoirs, with associated minerals playing a significant role in the dissolution processes. Metal ions in acidic fluids have been found to influence fluid properties and dissolution processes, impacting reservoir quality. Additional studies are needed to further understand the impact of associated minerals on the dissolution dynamics of carbonates.

Summary: This study investigates the formation mechanism(s) of dolostone in the Nanpanjiang Basin. It finds that dolostone formation consists of three phases, with the first phase formed by the reflux of platform-top evaporated seawater in the Early Triassic. The second and third phases of dolostone are interpreted to have formed at elevated temperatures during or after Late Triassic platform burial. The study also suggests that the same dolomite sample may retain well-preserved or altered data depending on the specific geochemical proxy used.

Summary: Understanding the development of syn-rift carbonate systems is complex, and their facies distributions can sometimes be difficult to predict due to key factors such as tectonics, eustasy, palaeogeography and climate. The study in SE Dahra Platform demonstrates that synsedimentary faults control reservoir architecture and predict heterogeneous distributions of carbonate facies, with local tectonic deformations and sea-level changes being primary controls on platform geometry and facies distributions.

Summary: This research characterizes fractures in the Judea Formation using a combination of available data. The limestone zone has more induced fractures compared to the dolomite zone, while the dolomite zone has frequent naturally occurring fractures that are open or partially filled. The fractures in the limestone zone are primarily caused by fracture of the limestone matrix and plastic deformation of the soft carbonate host rocks, while the fractures in the dolomite zone are primarily associated with dolomitization processes.

Summary: The study focuses on the Bonnevaux section in the Jura inner platform of France during the Middle Oxfordian period. It reveals that a sequence composed of microporous limestones can exhibit a wide range of original microfacies associated with different depositional environments. The reservoir qualities and transport properties of these microporous limestones show spatial evolution at the platform scale, with an increase in total porosity and permeability, and a decrease in trapped porosity. The increase in permeability is correlated with changes in the pore access radii and the control of meteoric pore-fluid flows by microporosity during burial diagenesis.

Summary: This study investigates the impact of mechanical layering and fractures on flood-related erosional undercutting and rapid recession of a spillway. It was found that the size of rock blocks, the orientation of fractures, and the occurrence of toppling collapse played a significant role in the process. The combination of mechanical contrasts between layers and natural fractures in competent layers contributed to exceptionally high rates of headward erosion.

Summary: Understanding fracture distribution and fault impedance across different lithologies is crucial for estimating flow properties in fractured reservoirs. This study focused on Cretaceous carbonate platform in Maiella Mountains, identifying two mechanical boundary types and applying outcrop findings to the subsurface. The identified mechanical boundaries were then used to implement reservoir static model in the subsurface for controlling vertical fluid flow in fractured reservoirs.

Summary: Identifying reservoir fractures, especially in highly complex carbonate reservoirs, has been a challenge. In this study, machine learning methods were used to classify fracture zones in the Asmari carbonate reservoir in the Middle East, with the support vector machine (SVM) outperforming other classification methods. The results showed that SVM-GWO offered superior accuracies in different population of algorithms, indicating its effectiveness in fracture detection.

Summary: The study indicates the presence of a dual permeability system in the Middle Permian Maokou limestone reservoir in the southern Sichuan Basin, mainly formed by karstification in the late Maokouan Age. Shoal facies, paleotopography, and syndepositional faults are the primary factors controlling the development and distribution of karst features within the reservoir. The highland edges, western lower slopes, and eastern upper slopes are identified as potential sweet spots in the reservoir.

Summary: This paper investigates the mechanical energy distribution in dowel-type joints in timber structures when using expansive kits. It was found that the compression caused by the expansive kit increases friction, leading to a higher load capacity of the joint. Through the establishment of a finite element model and validation with experimental results, it was confirmed that using expansive kit reinforcement can slightly improve the load capacity of the joint.

Summary: This article presents a simulation method for acid fracturing in fractured-vuggy carbonate reservoirs. By hierarchically treating the natural fractures and considering the acidization of the fractures in both inactive and activated states, this method effectively simulates the activation, propagation, interaction with natural fractures, and connection with cavities. It provides a stable and efficient approach for simulating acid fracturing in complex fractured-vuggy carbonate reservoirs.

Summary: The study reveals that the seismic events in L'Aquila in 2009 and Amatrice-Visso-Norcia in 2016 were caused by two seismogenic faults, with potential seismic activity in the Campotosto area. The Monte Gorzano Fault, previously considered an active seismic structure, is now suggested to have early geological origins. This new understanding of seismic activity provides valuable insights for earthquake hazard assessment in the region.

Summary: The study focuses on large discordant breccia bodies in the Gargano Promontory of southern Italy and utilizes UAV-based Structure from Motion Photogrammetry to document inaccessible cliff-side exposures. The breccias formed at different times and by different processes, possibly due to solution exploiting pre-existing fracture networks. The findings shed light on the tectonic and gravitational evolution in platform-to-basinal settings and the implications for fluid-flow migration and compartmentalization of tight carbonate reservoirs.

Field surveys revealed surface faulting and secondary effects like liquefaction, sinkholes, and landslides. The dataset collected from 222 observation points will be crucial for future studies on earthquake processes and assessing hazards associated with transcurrent faults.

Summary: Despite their different structural settings, the northern and southern outer Albanides have undergone a common tectonic evolution from detachment-dominated to ramp-dominated thrusting. The thickness of the Triassic evaporites and the rheology of the basement control the decoupling capacity of the upper decollement and the reactivation of the middle crustal decollement, respectively. The original continental margin architecture strongly influences subsequent convergent deformation.

Summary: This study investigates a buried extensional fault zone in southern Apennines, Italy, focusing on its growth mechanisms during the Cenozoic period. By analyzing seismic reflection profiles, well logs, and isochron maps data, the fault zone is identified as consisting of four segments cutting through different chrono-stratigraphic surfaces. The fault segments show scale-dependent geometries and underwent coalescence and fault linkage processes during the Miocene-Pliocene deformation. Pleistocene faulting further influenced the evolution of a coherent fault system.
