A study of 10 trains of gas-liquid mixtures (GLM) for the primary opening of productive layers with abnormally low reservoir pressure, which consist of the following reagents: a complex of surfactant, a complex stabilizers and builders, glycerine, caustic soda, GKZ-11.Vse investigated solutions have the ability to re-foaming.
