The gas well loading phenomenon is one of the most serious problems that reduces, and eventually cuts, production in gas wells. This phenomenon occurs as a result of liquid accumulation either water and/or condensate in the well bore. Over time, these liquids cause additional hydrostatic backpressure on the reservoir which results in a continual reduction of the available transport energy. The well therefore starts slugging which gives an even larger chance of liquid accumulation that completely overcomes the reservoir pressure and causes the well to die.the development of the loading phenomenon in a gas well. Typical solutions were to unload the well artificially, either mechanically using pumps or with gas lift kicking with nitrogen through coiled tubing. However, in addition to the expense and loss of production, artificial lift solutions remain temporary and the well is subject to reloading again.Therefore, thought was directed toward developing some solu- tions that enable the well to continuously unload itself without the aid of external help unloading operations [1,3].
