In the case of self-kill of wells, the gas flow velocity in the lifting column is not sufficient for carrying to the surface of the liquid, accumulated in the wellbore. To remove liquid from the bottom of wells, solid and liquid surfactants are used. As a result of conducted studies of surfactant compositions, the components of surfactant solutions were chosen to remove liquid from the bottom of wells.
