ABSTRACT:
A method for controlling water condensation in the pores of a near wellbore region of a permeable formation through which wet natural gas flows into an inflow section of an oil and/or gas production well, the method comprising controlling fluid transfer through the near wellbore region such that development of a water bank resulting from condensation of water in said region is inhibited or promoted. If the well is a gas production well then development of a water bank may be inhibited by controlling pressure drawdown, cyclic well shut in, fracturing and/or injection of heat generating and/or water transporting chemicals.
