Abstract:
gas oil relative permeability is the most important parameter in simulation of fluid flow in the gas condensate reservoirs . Experimental measurements of relative permeability need core samples with regular shape which is costly and time consuming. On the other hand experimental data of relative pemeability may also have significant error and uncertainty in many cases.one source of uncertainty is that the input to numeriacl simulator is uncertain and inaccurate; it may be reduced if the number of input parameters is decreased, especially if the parameters with greatest uncertainty are avoided. it is possible to impose only capillary pressure data, because relative permeability can be predicted consistently using specific models. the present methods which are based on capillary pressure considered the porous media as a bundle of capillary tubes; they indeed are mercury flow paths that are filled during MICP test at the certain value of capillary pressure.
