Annotation:

The paper is devoted to the peculiarities of the mechanism of water-gas impact (WGI) on the formation during the development of carbonate reservoirs. Various combinations of technologies elements used in the displacement of viscous oil by the WGI method are considered on the example of a separate experimental site with two injection and four production wells. Based on the research results, an analytical expression of the displacement coefficient dependence on the volume of the displacing agent pumping was obtained.
