Summary: This study explored the carbonate platform system of Turonian sediments in the Gulf of Suez and highlighted the significance of channelized reservoirs in oil production. The research analyzed facies change, depositional environment, and petrophysical characteristics to predict the distribution and discrimination of fluvial channel reservoirs. With the integration of petrography and petrophysics, the study identified optimal reservoir discrimination and rock typing, providing guidelines for future exploration and production in the basin.

Summary: The research focuses on examining the role of sedimentary cycles and tectonics in the quality of the Ahwaz Bangestan Reservoir, and identifying rock typing units. Understanding the relationship between interpretive data, diagenetic events, sedimentary cycles, and reservoir quality is crucial. The study reveals the impact of meteoric diagenesis and burial cement process on reservoir quality, and identifies different facies associations and their dynamic behavior.

Summary: The accurate characterization of shoal sediments is important due to erosion and difficulty in calculating the real thickness of granular shoals. This study describes the type and distribution range of carbonate rock shoal facies using the shoal-to-strata ratio. It concludes that platform margin shoals have the highest shoal-to-strata ratio and greater exploration potential. The shoal-to-strata ratios are more accurate than using shoal thickness to characterize sedimentary facies. The planar distribution diagram of the shoal-to-strata ratio can be used as a supporting map for sedimentary facies mapping.

Summary: This study investigates the distribution and reservoir characteristics of microbial carbonates in the upper submember of the Middle Triassic Leikoupo Formation in the western Sichuan Basin. It identifies high-quality reservoirs in the central area (regressive microbialites) and northern area (intraclast dolograinstone). The study proposes a depositional framework for microbialites and evaluates its control on reservoir quality, which is significant for further research on microbial carbonate reservoirs.

Summary: This study investigated the evolution of reefs and carbonate platforms in the Wan'an Basin, southwest of the South China Sea, and its significance for oil-gas exploration. Four evolutionary phases were identified based on seismic profiles and well data. The study found that crustal tectonic activity and eustasy played important roles in the growth and distribution of reefs and platforms.

Summary: Large areas of high-quality reservoirs in shallow-water lacustrine delta sand bodies in the early stage of retreating delta-front system are found in the central depression of the Songliao Basin. The reservoir quality changes during delta-front retrogradation are influenced by factors such as sedimentary facies, diagenesis, and mineral composition.

Summary: The study of Barremian-Cenozoic depositional sequences in the northern Orange Basin, SW, South Africa, using seismic stratigraphy principles revealed the distribution of potential hydrocarbon reservoirs and the interplay of tectonics and sedimentary processes. Seven depositional sequences were mapped, identifying potential stratigraphic reservoirs in Barremian-Aptian and Albian sequences based on seismic-lithofacies modelling.

Summary: The eastern sector of the Mesozoic Iberian basin belongs to the 'Mediterranean type' Triassic, characterized by a stratigraphic record with two carbonate Muschelkalk units. The evolution of the platform morphology from an epicontinental platform to a lower energy rimmed shelf is depicted through the deposition of shallow-water carbonates and tidal/lagoon environments.

Summary: This study re-evaluates the reservoir characteristics and facies identification of the Sui Main Limestone in the Qadirpur field of Pakistan's Middle Indus Basin using petrophysical analysis and rock physics modeling. The study finds that the limestone exhibits micro-fractures and well-connected secondary pores, and the clean carbonate intervals have the potential for hydrocarbon accumulation. This research is significant for improving reservoir quality prediction in heterogeneous carbonate reservoirs and optimizing field development.

Summary: This study analyzed the outcrops in the Wushi area of the northwestern margin of Tarim Basin to reveal the main types and controlling factors of platform margin reef-shoal reservoirs. Relative sea-level change, palaeosource, and paleogeomorphy were identified as the main controlling factors for the development of platform margin reef-shoal reservoirs.

Summary: The Upper Carboniferous sandstone reservoir in the Ordos Basin is crucial for natural gas exploration. This study analyzed 157 Jinci sandstone samples to understand the reservoir's material composition and pore structure. The results showed that the reservoir is mainly composed of quartz arenite and sublithic arenite, with quartz being the dominant detrital particle. The cement consists of siliceous material, clay minerals, and carbonate. Different pore-throat structures and radius distributions were identified. Factors such as deposit composition and diagenetic modification were found to influence the reservoir's pore structure. The study also predicted the reservoir quality based on lithological characteristics and diagenetic-controlled pore-throat evolution patterns.

Summary: The objective of this study is to analyze the facies, depositional environment and reservoir quality of the Early Cambrian Xiaoerbulake Formation in the Tarim Basin. The study shows that the deposits of the Xiaoerbulake Formation occurred in a ramp setting, with seven facies associations and ten facies types. High-quality reservoirs were found in the high-energy shoal environments, characterized by different pore space types. This research contributes to our understanding of the stratigraphic framework, sedimentary-facies evolution, and high-quality reservoir distribution, aiding in hydrocarbon exploration and production.
