The problem of steady-state flow of a gas-condensate 
mixture near an operating well is considered. The effect of capillary 
forces on condensate distribution in a porous medium is studied both 
analytically and numerically. It is shown that capillary forces can 
serve to decrease the amount of condensate, with the effect occurring 
in both cases - wetting and nonwetting liquid phases.
