The paper discusses two technologies for implementation of gas methods used in oil field development. - alternating gas-water injection and water-gas stimulation in which combined injection of displacement agents (gas and water) is used.

OJSC “RITEK” is successfully implementing the enhanced oil recovery by means of water-gas injection into the formation.

Water-gas stimulation is stimulation of the oil-bearing formation in which oil is displaced by a maximum possible wide frontal gas fringe followed by water injection. Gas flood ensures high displacement efficiency, while water flood ensures high sweep factor.
