Abstract
Many of the largest Cenomanian gas deposits in Western Siberia are in the final stage of development. There are the liquid loading in the well and gas production decrease. The choice of artificial lift technologies is due to both the technological features of the production process at a particular field, and the economic efficiency of their application. The technology of injection foaming surfactants into the well is widespread in the world, which is characterized by a relatively low level of capital investments and a high level of efficiency, including economic efficiency. There are difficulties associated with the prediction of the pressure gradient under foam flow in a production tubing. This article describes a method for calculating the pressure gradient under foam flow. The results of applying this method for calculating pressure gradient in gas wells of one of the Russian fields on the final stage of development.
