Relative Permeability of Porous Media with Nonuniform Pores

Geofluids, 2020
Most classical predictive models of relative permeability conceptualize the pores in porous media as assemblies of uniform capillary tubes with different sizes.

Insights, Trends and Challenges Associated with Measuring Coal Relative Permeability [PDF]

E3S Web of Conferences, 2019
Due to the poroelasticity of coal, both porosity and permeability change over the life of the field as pore pressure decreases and effective stress increases.

Gyrotropic impact upon negatively refracting surfaces [PDF]

, 2005
Surface wave propagation at the interface between different types of gyrotropic materials and an isotropic negatively refracting medium, in which the relative permittivity and relative permeability are, simultaneously, negative is investigated. A general

Application of Artificial Neural Networks for Predicting Relative Permeability in Talang Akar Formation [PDF]

E3S Web of Conferences
Relative permeability is a substantial parameter for estimating multi-phase fluid flow in porous rocks. It is a complex physical property that is influenced by the behavior and interactions between the fluid and rock phases.
