    Reflections on the role of chemical osmosis mechanisms on the long-term behavior of a collapsed salt cavity by Ledoux, Emmanuel, Hertz, Emmanuel, Robinet, Jean-Charles, Combes, Pierre

    Published 2022-10-01
    “…Recent work on chemical osmosis in clay media, motivated by research on the geological storage of nuclear waste in a clay layer, raises questions about the role of this mechanism on the long-term behavior of the system.Based on a bibliographical approach, the article presents a brisk synthesis of the theory of chemical osmosis and discusses its application to the case of clayey rocks which can constitute imperfect membranes capable of generating osmotic pressures.First, the article presents the equations representing the flow of the fluid and the solute transport according to a simplified formulation adapted to the geometry of the system. …”

    Enhancing hydraulic fracturing efficiency through machine learning by Ali Karami, Ali Akbari, Yousef Kazemzadeh, Hamed Nikravesh

    Published 2025-01-01
    “…These models were specifically employed to predict and assess fracture width based on a variety of geological and operational parameters: geometric factors (γ), Shear Modulus (G), Poisson’s ratio (ν), viscosity of the fracturing fluid (µ in centipoise), crack height (h), fluid efficiency (η), injection time (t), and crack length (x). …”
