Claystone porosity
WebOct 9, 2024 · The bulk (total) porosity ϕ of this claystone is about 13 per cent. Mercury intrusion is a porosimetry technique allowing the determination of the distribution of the entrance radii of pores (throats). The porous network, represented in Fig. 2, is unimodal and composed of pore throat radii between 0.002 and 0.1 μm in size. WebSep 1, 2024 · Shale porosity typically decreases with depth, following an exponential decay (e.g., Athy, 1930; Sclater and Christie, 1980). The decrease in porosity is also indicated by a decrease in mean size of pores in shales with depth (Fig. 2b; Selley and Sonnenberg, 2015), according to the pore-size scale of the IUPAC classification (Rouquerol

WebIn this paper, a coupled hydro-mechanical (HM) model that incorporates double porosity poroelasticity is developed to simulate the gas migration process in saturated claystone. The model accounts for the HM behavior of both the porous medium (which represents the matrix) and the fractured medium (which represents the fractures).
