Yes! This is frequently done to predict sales stream volumes or for water disposal.
Water that can be condensed from gas is calculable, search on Bukacek or McKetta-Wehe methods.
Hydrocarbons that condense from gas are also calculable using PVT software, such models are made to predict condensate yields for future production and can be simplified in black-oil tables in reservoir simulation.
Produced water from formation will add to condensed liquids. That is harder to predict and will be dependent of the calibration of a reservoir model.
You should first plot the phase envelope and water dew point curve for the hydrocarbon mixture. At a given pressure, as the temperature is decreased from a high value, at water dew point temperature, water starts condensing. Almost all of water condenses at hydrocarbon dew point temperature which is a point on the phase envelope. After this hydrocarbon mixture starts condensing and all of hydrocarbon mixture condenses at bubble point temperature which is a point on phase envelope. So between water dew point curve and phase envelope, water condenses whereas inside the phase envelope, hydrocarbon mixtures condenses. Water is polar whereas hydrocarbons are non-polar so they exist as separate phases. Barring few exceptions, this is how a hydrocarbon- water system behaves at decreasing temperature and fixed pressure.
