The answer from Blacksmith37 is exactly correct for the information provided. There are formulas for converting a gas analysis to component parts, but without a gas analysis then we would have to guess one. If I guessed CBM, then the answer is "zero". If I guessed a conventional gas with a 1600 BTU/SCF heating value the answer is "a lot".
You really can get what is there if you get it cold enough.
I think that a 10-15% loss for energy required for liquefaction should also be included - unless your condensate can be used for this and/or is a waste product that you cannot sell.
Other place I worked with was producing 120 m3/d of condensate for 4 KM3/d of gas during summer with a dew point of 5 deg C.. during winter it can go down to 60 to 80 m3/d
I was trying to have some simple calculation just for estimate basis
Put everything in the gas analysis in terms of mass fraction, then convert the gas flow rate to mass basis. Take out the mass of Water, Methane, Carbon Dioxide, Nitrogen, Hydrogen Sulphide and other non-condensibles. The rest ought to be what is available to you to produce liquids. You would then likely need to adjust for a recovery efficiency, as stated in the above posts. The remaining consideration is then to determine if you are trying to produce NGL (which has a product specification based on constituent fractions) or stabilized condensate (which has an RVP specification) or both.
