A METHOD OF CONTROLLING WATER CONDENSATION IN A NEAR WELLBORE REGION OF A FORMATION

摘要

A method is disclosed for controlling water condensation in the pores of a near wellbore region of a permeable formation through which wet natural ga s flows into an inflow section of an oil and/or gas production well, the met hod comprising controlling fluid transfer through said region such that deve lopment 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 developm ent of a water bank may be inhibited by controlling pressure drawdown, cycli c well shut in, fracturing and/or injection of heat generating and/or water transporting chemicals.
