Severalother authorshave proposedsimilar water relative permeabilityequations with different exponentsfor other types of porous media. 521 were proposedfor unconsolidatedsands with a single grain structurewhich may not be absolutelyuniform in pore size but should have a nalrow rangeof pore sizes. Corey compared the calculated values of oil and gas relative permeabilities for poorly values and obtainedgood results. Corey concludedthat the equationsare not valid when stratification,solutionchannels,fractures, or extensiveconsolidationis present.

Using this relationship, two-phaserelative permeabilitiesare given by k "rwt 2 + l A r - / S * l \vw (36) , and k . *, and k-*, are wetting and nonwettingphaserelative permeabilitiesrespectively. The valuesof tr and Po are obtainedby plotting (S* - S*,)/(l - S*,) vs.
