Abstract: A method of reducing condensate accumulation in a natural gas well may include a first step of determining a pressure and a temperature of the natural gas well. The method may further include a second step of determining a dew point temperature based on the pressure of the natural gas well. The method may also include a third step of determining a cricondentherm temperature of the natural gas well. The method may also include a fourth step of heating the natural gas well to a temperature above the dew point temperature; and a fifth step of limiting the temperature of the natural gas well to the cricondentherm temperature.
