FIELD: oil and gas industry, particularly for lifting liquid and gas from well by lifting gas injection into well.
SUBSTANCE: method involves injecting lifting gas into well so that lifting gas passes into liquid or gas flow as accumulation of finely dispersed bubbles. The lifting gas is injected through porous wall having a number of orifices for lifting gas injection.
EFFECT: increased method efficiency and device reliability due to increased oil lifting stability.
