Corey coefficients
 Permeability function for unsaturated soil)
In 1954, Corey combined predictions of a tube-bundle model with his empirical expression for capillary pressure to obtain expressions for gas and oil relative permeabilities. In 1964, Brooks and Corey extended Corey’s results using Eq. 1for capillary pressure to obtain the following expressions for oil and … See more In 1956, Corey and Rathjens extended Corey’s earlier work to explain the effect of laminations on gas/oil relative permeability relations. They considered flow parallel and flow … See more Other researchers have offered correlations for laboratory measurements of relative permeabilities.
