Аннотация: Waterflooding - is currently the most popular method of oilfield development, but very often it does not guarantee high development effectiveness. This fact is the significant problem taking into account that the amount of hard to recover reserves is being increased constantly. The combined water and gas injection to the layer enables usto essentially increase the oil recovery ratio. Use of associated gas for water-gas influence also enables us to solve a problem of its utilization.About 100 field applications of WGI are known since this technology was used in North Pembina (Canada 1957 year) for the first time, and only single cases failed.Today, different technologies of WGI are applied that can be classified in two ways: alternate or simultaneous injection of water and gas (WAG or SWAG Injection).However, traditional ways of applying WGI were not widespread in Russian oil fields, but instead significant amounts of associated gas were flared. WAG compressor technology requires the purchasing of import equipment, essential investments in the initial stage, and high operating costs. Besides compressor stations, the construction of gas treatment plants is required.The separation of rich fraction from associated gas is required for the proper work functioning of compressors. These fractions are not always utilized and than the usage of dry gas for WGI it is less effective in terms of increasing oil recovery.
