WebJan 19, 2016 · The permeability of one region is one-fourth that of the other region. The relative permeabilities are given by Eqs. 2 and 3 with λ = 2 and with Sor = Sgc = 0.20. Corey and Rathjens [3] noted two consequences of laminations: bumps in the relative permeability relationships and a shifting of the critical gas saturation.

In multiphase flow in porous media, the relative permeability of a phase is a dimensionless measure of the effective permeability of that phase. It is the ratio of the effective permeability of that phase to the absolute permeability. It can be viewed as an adaptation of Darcy's law to multiphase flow. For … See more The above form for Darcy's law is sometimes also called Darcy's extended law, formulated for horizontal, one-dimensional, immiscible multiphase flow in homogeneous and isotropic porous media. The interactions … See more Let $${\displaystyle K_{\mathit {row}}}$$ be oil relative permeability, and let $${\displaystyle K_{\mathit {rw}}}$$ be water relative permeability. There are two ways of scaling … See more After Morris Muskat et alios established the concept of relative permeability in late 1930'ies, the number of correlations, i.e. models, for relative … See more In multiphase systems Relative permeability curves of each fluid phase (i.e., water, oil, gas, CO2) can be averaged using the concept of See more Water saturation $${\displaystyle S_{\mathit {w}}}$$ is the fraction of porevolume that is filled with water, and similar for oil … See more The Corey-correlation or Corey model has only one degree of freedom for the shape of each relative permeability curve, the shape parameter N. The LET-correlation adds more degrees of freedom in order to accommodate the shape of relative permeability curves … See more Relative permeability is just one of the factors that affect fluid flow dynamics, and therefore can’t fully capture dynamic flow behavior of porous media. A criterion/metric has … See more WebThe permittivity is because of polarization whereas the permeability is because of magnetization.
