The consequences of water intrusion into gas and gas condensate wells are characterised. The need to intensify the removal of fluids from the bottom of the well to the surface is justified. Methods of preventing water ingress to the bottom of the well are briefly described. The main disadvantages of gas well isolation are considered. The characteristics of the methods of removing water from gas wells are given. The advantages of the method of intensifying the removal of liquid from the bottom of gas wells to the surface by means of foaming surfactants are enumerated and the expediency of its use is substantiated. The main methods of pumping foaming surfactants into the well are considered. The main methods of determining the foaming characteristics of surfactants are characterised. The essence of the Ross-Miles method and the principle scheme of the Ross-Miles device are considered in detail, and the main advantages of the Ross-Miles method in comparison with other methods are enumerated. The technical characteristics of the Ross-Miles apparatus are given. The procedure for carrying out laboratory tests using the Ross-Miles method is described in detail. The results of laboratory studies on the determination of the foaming ability of surfactant solutions in distilled and mineralised water at temperatures of 20 ± 2 °C and 50 ± 2 °C by the Ross-Miles method are given. Based on the results of laboratory tests, it is recommended that the surfactant with the highest foaming ability be used to intensify the removal of liquid from gas wells. As a result, the expected increase in gas well flow rate is 10-15%. Recommendations for pumping foaming surfactants into gas wells are given
