    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
    “…Shale samples with strong deformation have a smaller mesopore volume; but due to the presence of organic-clay aggregates, a larger mesopore-specific surface area embarks on these samples. According to fractal dimension calculations, it is found that in strong deformed shale, more multiple dimensions of the pore system tend to represent rougher pore surfaces and more irregular shapes. …”
