Effects of clay minerals and organic matter on pore evolution of the early mature lacustrine shale in the Ordos Basin, China

Guanping Wang et al.

Summary: This study investigates the controls of organic matter and clay minerals on the pore structure evolution of the lacustrine organic-rich Chang 7 Shale. The results show that micropores and mesopores contribute to the main storage space in the shale. Organic matter content influences the development of micropores, while total clay content is correlated with mesopores volume. Different clay minerals control pores of different sizes. Thermal maturity has a positive effect on pore volume and porosity. Clay mineral conversions have positive effects on pore volume, except for the smectite-illite conversion which negatively affects pore connectivity. Chlorite also plays a role in controlling macropore volume, porosity, and pore throat radius.

Pore system of the multiple lithofacies reservoirs in unconventional lacustrine shale oil formation

Guanping Wang et al.

Summary: This study systematically analyzed the overall pore system of the Triassic Chang 7 lacustrine shale formation in the Ordos Basin, China, and identified the different effects of rock components and diagenetic processes on the development of multi-lithologic pore systems. The results showed the negative impact of organic matter on pore volume and the positive influence on pore throat, while clay minerals generally played a negative role except for in organic-rich laminated shale. Quartz and feldspar were found to contribute to pore development, while calcite and dolomite had negative effects. Pyrite and siderite facilitated pore throat preservation but inhibited pore space development. This study contributes to a better understanding of sweet spot prediction in lacustrine shale formations.

Geological controls on the pore system of lacustrine unconventional shale reservoirs: The Triassic Chang 7 member in the Ordos Basin, China

Guanping Wang et al.

Summary: The main pore space in the lacustrine Chang 7 Shale is dominated by macro- and meso-pores, while the pores within organic matter are rarely observed. Quartz promotes the development of macro- and meso-pores, while clay minerals show negative effects on their heterogeneity. A critical maturity point of 0.8% Ro is observed for the change of the pore system, and both fractal dimensions and pore structure proxies show inverse trends before and after this point. These findings contribute to a better understanding of pore system evolution and identification of high-quality reservoirs in lacustrine shales.

Lithofacies and pore features of marine-continental transitional shale and gas enrichment conditions of favorable lithofacies: A case study of Permian Longtan Formation in the Lintanchang area, southeast of Sichuan Basin, SW China

Enze WANG et al.

Summary: This study focused on the Permian Longtan marine-continental transitional shale in the southeast of Sichuan Basin. Petrology and geochemical analysis were used to classify the lithofacies types and analyze the key controlling factors of physical properties and gas content. The results showed that the organic-rich argillaceous shale is the most favorable lithofacies, clay mineral content is the main controlling factor of physical properties, and TOC content has the most important effect on gas content. Compared with marine shale, the marine-continental transitional shale has wide distribution range and strong heterogeneity in TOC content, porosity, and pore structure parameters.

Some new thoughts of definitions of terms of sedimentary facies: Based on Miall's paper (1985)

Zeng-Zhao Feng

Summary: Recently, the Journal of Palaeogeography has received manuscripts from authors in China, Pakistan, Lithuania, Morocco, South Africa, etc. These authors have used Miall's paper (1985) as a reference in their studies, selecting rocks from each bed in clastic sections and considering them as lithofacies. However, this approach does not align with the definition of lithofacies. The author of the current paper has written several papers pointing out these problems and hopes to encourage academic discussions and geological practice to gradually solve them.

Study on pore evolution and diagenesis division of a Permian Longtan transitional shale in Southwest Guizhou, China

Xiao Ma et al.

Summary: Organic-rich shales in southern China were studied to investigate the pore evolution and organic matter evolution during diagenesis. The study found that the evolution of pore structure was intermittent and influenced by factors such as maturity and clay mineral composition. The abundance of pores in organic matter and the transformation of clay minerals were key factors affecting the pore structure evolution.

Sedimentary Evolution Characteristics of Fine-Grained Lithofacies under the High-Resolution Isochronous Shelf System: Insights from the Wufeng-Longmaxi Shales in the Sichuan Basin

Guanping Wang et al.

Summary: This study investigated the fine-grained deposition and evolution characteristics of the Wufeng-Longmaxi shales, key targets for Chinese shale gas exploration. The research accurately identified favorable lithofacies for shale gas exploration and discussed the differential evolution of lithofacies in the sedimentary system tract. The study is significant for further exploration of marine shale and improvement of the theory of shelf fine-grained sedimentary systems.

Analysis of Sedimentary Environment Conditions for Lacustrine Fine-Grained Sedimentary Rocks and Its Control of Lithofacies Development: A Case Study of the Lower Submember of Member 3 of Shahejie Formation in FY-1 Well, Dongying Sag, Bohai Bay Basin, China

Jun Peng et al.

Summary: This study focused on the muddy shale of semideep and deep lacustrine facies in the lower submember of Member 3 of Shahejie Formation in the Dongying Sag area in East China. By analyzing geochemical data and utilizing various technologies, the study revealed a cyclical environmental change that influenced lithofacies development, showing transitions in water depth, paleoclimate, paleoredox, and paleosalinity over time. The lithofacies primarily consisted of organic-rich mudstones, lime mudstones, and limestone, with the sedimentary environment controlling mineral composition and content. The cyclical environmental changes also impacted the positioning of lithofacies within the sequence stratigraphic framework.
