WebApr 12, 2024 · The porosity of these models distributes from 3.2% to 19.4%. Single-phase flow simulations were performed in X, Y, and Z directions to obtain absolute permeability (Fig. 5 b). The permeability distributes from 5 to 29.9 × 10 −3 μm 2, belonging to low and medium permeable rocks. Obviously, the pore-scale models are anisotropic for the ... WebThe permeability of a porous medium is a measure of the ease (or difficulty) in which a fluid can flow through the pores of the medium. Permeability is a property of the porous medium which in our case is the reservoir rock.

WebNov 19, 2024 · Rock permeability depends on ambient pressure, temperature and deviatoric stresses. In sedimentary rocks the permeability is affected by quartz content, gravel fractions and grain sorting. There are two different permeability models for rocks: the capillary model of pores and the fracture model. WebOct 5, 2024 · Stone permeability is related to stone porosity. Permeability is a measurement of how easily water can move from one pore to another within natural stone. Scientists use water to measure permeability because it flows naturally and will always try to fill pores in materials where they exist. how to see my oer
