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 …

The relative permeability is the ratio of the permeability of a specific medium to the permeability of free space µ0. µr = µ / µ0(1) where. µr = relative permeability. µ = permeability of the medium …

Relative permeability is defined as the ratio of effective permeability to absolute permeability, indicating the ability of a porous medium to allow fluid flow in the presence of other fluids.

Apr 5, 2022 · Relative permeability to oil (K ro), gas (K rg), or water (K rw) is the ratio of effective permeability of oil, gas, or water to absolute permeability. Relative permeability can be …

Interpretation and use of relative permeability data to predict individual well or reservoir performance can be complicated by lateral variations in rock properties.

The concept of describing this multiphase flow in reservoirs is known as relative permeability, which is defined as the ratio of the effective permeability of a fluid to the absolute permeability …

If S e f f <0 Seff <0 then the relative permeability is zero, while if S e f f> 1 Seff>1 then the relative permeability is unity. Otherwise, the relative permeability is given by the expressions below.

Relative permeability is calculated based on the upstream saturation. If the two cells are at the same level, then the upstream cell is simply the cell with higher pressure.

Paramagnetic materials are attracted to magnetic fields, hence have a relative magnetic permeability greater than one (or, equivalently, a positive magnetic susceptibility).

Jan 29, 2025 · Relative permeability has important implications for flow of reservoir fluids. A number of models have been developed to relate relative permeability to other reservoir …
