Summary: The study investigates the diagenetic impacts on reservoir properties of sandstones in the Early Cretaceous Lower Goru Formation in the Lower Indus Basin of Pakistan. The results reveal that chlorite is the dominant diagenetic constituent affecting the porosity of the sandstones. Different diagenetic events like compaction, cementation, dissolution, and mineral replacement have significantly altered the original rock properties and reservoir characteristics of the sandstones.

Summary: An integrated approach was used to analyze the role of depositional and diagenetic controls on reservoir quality in the Lower Goru Formation in Pakistan's Middle Indus Basin. It was found that high permeability and high porosity reservoirs are associated with well-sorted and medium-grained sandstones, while chlorite coating and quartz cementation are the major controlling factors. This study provides valuable insights for exploration and field development planning in stratigraphic traps.

Summary: This study investigated the relationship between chlorite rims and porosity evolution in the Chang 7 sandstones of the Upper Triassic Yanchang Formation in the Ordos Basin in northcentral China. The results showed that chlorite rims inhibited the formation of quartz cementation, but other factors such as compaction and other cements also controlled the porosity evolution of sandstones. Chlorite rims only played an important role in porosity preservation when quartz cementation was the main process of porosity destruction.

Summary: This study investigates the geochemical system of the Rosebank field in the Faroe-Shetland Basin, focusing on the dissolution and precipitation effects at the basalt-sandstone interface. The results show that the dissolution and precipitation processes control the basalt dissolution rate, while diffusion has minimal impact on reservoir quality.

Summary: This study focuses on the Early Cretaceous Lower Goru sand intervals in the Lower Indus Platform area. By using a third-order sequence stratigraphic framework, the depositional architecture and reservoir geometries of the Lower Goru Formation are understood. The research suggests that the Lower Goru Formation was deposited in river-dominated deltas and there may be different river lobes due to auto-cyclic switching of river distributaries. Proven reservoir intervals of the formation are concentrated in lowstand system tracts, and the net sand and porosity maps, gross depositional map, and depositional cross section provide insights into potential sandstone reservoirs and their geometries.

Summary: The analysis of Talhar shale in well 2 of Nur-dep#1 in the Southern Lower Indus Basin, Pakistan, reveals the presence of smectite and illite, with increasing illite content with depth. Different components such as chlorite, kaolinite, and illite show variations in distribution and quantity with depth changes.

Summary: This study investigates the impact of illitization on sandstone reservoir properties by examining the diagenetic history of the Mt. Simon reservoir complex. Illite was identified as the major clay component in all samples, with illitic clay coatings in the lower Mt. Simon reservoir identified as a major control on reservoir properties. Two major events of illitization were identified throughout the Mt. Simon with varying ages attributed to mineralogy controlled by depositional changes and evolution of the greater basin.

Summary: This study investigated the impact of chlorite and microquartz grain coatings on the overgrowth of quartz and feldspar. The experimental results showed that the volume of precursor chlorite plays a significant role in the formation of the coatings. The findings provide quantitative data for describing diagenetic changes in mesodiagenetic environments.

Summary: The turbidite sandstone of the Agat Formation is an important hydrocarbon reservoir in the Norwegian North Sea, and its reservoir quality is greatly influenced by diagenesis. Early diagenesis results in the formation of chlorite coatings, which control the reservoir quality. Calcite cementation and K-feldspar dissolution in late diagenesis affect the permeability of the reservoir.

Summary: This study examines the cementation characteristics and their impact on sandstone reservoir quality in selected fields in the Euphrates Graben area, Syria. The presence of quartz, kaolinite, and carbonate cements, as well as different lithofacies, influence porosity and permeability in the studied formations. The Post Judea Sandstone Formation is predicted to have the best reservoir quality due to extensive cementation resulting in high porosity and permeability.

Summary: This study focuses on the characteristics and abundance of chlorite in deep sea turbidites and its impact on reservoir quality. The results show that grain replacing chlorite, clay replacing chlorite, and chlorite coatings are observed in both reservoirs but with different textural configurations. These findings are important for understanding the diagenetic process and the influence of material provenance on reservoir properties.

Summary: The study investigated the impact of diagenesis on pore systems in different lithofacies of Wufeng-Longmaxi shale from Sichuan Basin, China. Different lithofacies showed varying diagenetic pathways and evolution of pore systems under the same burial history. Diagenesis played a crucial role in determining the final status of the initial pore space and controlling the distribution of migrated OM, influencing the development of dominant OM pores in the entire pore spectrum.

Summary: This study focuses on the diagenetic evolution of the reservoir in the E(3)w(3) member of the Oligocene Weizhou Formation in Beibuwan Basin, northern South China Sea. The occurrence states and effects of different clay minerals, including chlorite, illite, kaolinite, and quartz cement, are analyzed. The study identifies three different occurrences of chlorite and three major types of diagenetic kaolinite. The presence of chlorite coating has a significant effect on quartz overgrowth.

Summary: This study used a rock physics template (RPT) approach to model the impacts of mechanical compaction and chemical diagenesis on porosity reduction in the Barail Sandstone. This study also analyzed the effects of diagenesis, rock frame constituents, and pore fluids on seismic amplitude response using a probabilistic amplitude variation with angle (AVA) approach.
