One of the most promising fields of RITEK's activity is design of recovery enhancement technologies. To this end the company has elaborated a production enhancement method called WAG treatment, which currently undergoes pilot testing. WAG technology is a profound modernization of invention made by famous oil-well expert I. N. Strizhov back in 1950. He suggested that production of oil fields  can be enhanced by highly compressed gas mixed with oil. Theoretically, it should guarantee 100% displacement. The insufficiency of the suggested method is that it has low coverage factor with poor efficiency of such formation treatment. The leading specialists of RITEK managed to handle the problem, which is proved by the patents of Russian Federation № 2142045 and № 2238389. Their decision retains normal coverage factor corresponding to usual water flooding and raises recovery from 15-25% to 30-50%. When WAG technology is applied, the oil is displaced by frontal gas rim of maximal coverage, after which the water is pumped. In this case the gas provides for high displacement rate, while the water helps to keep a high level of displacement coverage.
