Abstract
Gas-condensate flow around the wellbore is quite different from conventional gas oil flow. This is mainly due to complicated velocity effects on relative permeability in these very low interfacial tension systems. In the current study, it has been proposed that the desirable velocity effect on gas-condensate relative permeability is the result of inertial force. Having said that, inertial number, which is the ratio of inertial force over capillary force, could be a better candidate compared to capillary number when somebody deals with the modeling of gas-condensate relative permeability. A generalized correlation was obtained for gas-condensate relative permeability with applying this new approach. The results are promising. This approach is not only needs less core data, but also it is much simpler and even more accurate compared to previously developed equations using capillary number.
