Equations estimate relative permeability of mixed wettability shaly sands

04/30/2001
New equations for estimating the relative permeability curves for both water-oil and gas-oil systems have been developed for shaly sands in mixed wettability formations of the Western Desert in Egypt.These correlations also may be used in other regions of the world.The developed equations have good agreement with laboratory data.Permeability correlations Click here to enlarge imageRelative permeability is a direct measure of a porous medium's ability to conduct one fluid when one or more fluids are present. These flow properties are the composite effect of pore geometry, wettability, fluid saturation, and saturation history.1 2 The direct determination of relative permeability from s...
