    The Role of Microfabric and Laminae on Pore Structure and Gas Transport Pathways of Marine Shales from Sichuan Basin, China by Yi Shu, Shang Xu, Feng Yang, Zhiguo Shu, Pan Peng, Senxin Huang, He Zhen

    Published 2020-01-01
    “…This study investigated the effects of microfabric and laminae on the pore structure and gas transport pathways of the Silurian Longmaxi shales from Sichuan Basin. 23 shale samples with varied lithofacies were comprehensively investigated by mineralogy, organic geochemistry, pycnometry, and low-pressure nitrogen adsorption analysis. …”

    Relationship between Tectonism and Composition and Pore Characteristics of Shale Reservoirs by Fuhua Shang, Yanming Zhu, Haitao Gao, Yang Wang, Ruiyin Liu

    Published 2020-01-01
    “…To explore the relationship between tectonism and composition and pore characteristics of shale reservoirs, this research carried out mineralogy tests, organic geochemistry tests, field emission scanning electron microscopy (FE-SEM) experiments, and low-pressure gas adsorption (LPGA, N2 and CO2) experiments on the shale samples of various deformation intensities from Southwestern China. …”

    Gas Chromatography Coupled to High Resolution Time-of-Flight Mass Spectrometry as a High-Throughput Tool for Characterizing Geochemical Biomarkers in Sediments by Hector Henrique Ferreira Koolen, Clécio Fernando Klitzke, Joe Binkley, Jeffrey Patrick, Ana Cecília Rizatti de Albergaria-Barbosa, Rolf Roland Weber, Márcia Caruso Bícego, Marcos Nogueira Eberlin, Giovana Anceski Bataglion

    Published 2018-01-01
    “…GC-HRTofMS reduces both sample preparation time and the number of chromatographic runs compared to traditional methodologies used in organic geochemistry. Particularly, the approach based on in-situ derivatization thermal desorption represents a very simple method that can be performed in-line employing few milligrams of sediment, eliminating the need for any sample preparation and solvent use. …”

    Influence of quartz types on mechanical parameters in the early silurian Longmaxi shale, Sichuan Basin by Qin Zhang, Feng Liang, Qun Zhao, Wen Liu, Weiliang Kong, Wanli Gao, Xinyu Zhang, Guangyin Cai, Tianquan Qu, Zhen Qiu

    Published 2024-12-01
    “…After systematic analysis of organic geochemistry, mineral composition, cathodoluminescence observation, major/trace elements, and log interpretation and calculation of shale mechanical parameters, the genetic mechanism of quartz was analyzed and the percentage of quartz of different origins and the influence on rock mechanical properties were evaluated quantitatively. …”

    Fractal Characteristics of Pore Structure of Longmaxi Shales with Different Burial Depths in Southern Sichuan and Its Geological Significance by Manping Yang, Yanyan Pan, Hongye Feng, Qiang Yan, Yanjun Lu, Wanxin Wang, Yu Qi, Hongjian Zhu

    Published 2024-12-01
    “…We used two groups of Longmaxi samples, outcrop shale and middle-deep shale, to investigate the pore structure fractal features at varying burial depths using a combination of mineralogy, organic geochemistry, scanning electron microscopy (SEM), and low-temperature gas (CO<sub>2</sub>, N<sub>2</sub>) adsorption. …”
