Understanding Relative Permeability Concepts
Relative permeability is a crucial property of porous mediums determining fluid transmission capacity. Learn about two-phase relative permeability, correlations, and methods in this comprehensive guide. Explore various correlations like Wyllie and Gardner, Torcaso and Wyllie, Pirson’s, and Coreys's Method for gas-oil and water-oil systems. Gain insights into deriving relative permeability from capillary pressure data for drainage in water-oil scenarios. Discover the significance of relative permeability in oil and gas exploration.

RELATIVE RELATIVE PERMEABILITY CONCEPTS PERMEABILITY CONCEPTS The absolute permeability is a property of the porous medium and is a measure of the capacity of the medium to transmit fluids. When two or more fluids flow at the same time, the relative permeability of each phase at a specific saturation is the ratio of the effective permeability of the phase to the absolute permeability,
