Currently, a large number of Cenomanian gas storages inWestern Siberiaare at the final stage of development. Gas production from such storage is accompanied by the accumulation of different types of liquid at the bottomhole. One of the methods of solving this problem is the introduction of a foaming agent into the well. To date, there are no computational models that allow us to predict with a high level of accuracy the pressure loss in the tubing of a gas well working with surfactant in the flow. The existing few computational models were created on the basis of bench studies under atmospheric conditions, and the results obtained by them have significant errors. For the study and modelling of gas-liquid flows with surfactant taking into account the influence of pressure, temperature, water-gas ratio and other key parameters, an "Experimental facility to simulate gas-liquid flow and dynamic processes in the tubing of a gas well" was developed and implemented.
