    Constructions of multi-scale 3D digital rocks by associated image segmentation method by Haiyan Wang, Xuefeng Yang, Cong Zhou, Jingxu Yan, Jiaqi Yu, Kui Xie

    Published 2025-01-01
    “…Digital rocks constructed from micro-CT image at a single-resolution face limitations in accurately identifying the entire pore space and mineral components of tight sandstones, due to their high content of nanoscale pores and clay. Consequently, the porosity values derived from such digital rocks are significantly lower compared to those obtained through laboratory measurements, resulting in discrepancies between the measured and calculated petrophysical properties. …”
