This article analyzes the experience of operating the pump-ejector systems in the implementation of SWAG at the Samodurovskoye field. The data of the field tests of the pump-ejector systems, the parameters of the system operation are given, the failure analysis of the constituent elements is described in detail (which contributes to the further development of the SWAG technology and equipment for its implementation). A new technical solution has been proposed, which consists in the concentrated injection of a mixture with the highest gas content into wells that open reservoir zones with the largest residual reserves ("smart" injection). The conducted studies will help to more actively introduce SWAG in the fields. The proposed solution makes it possible to multiply the volume of irrationally used associated petroleum gas (which is otherwise simply flared), thereby increasing oil recovery and profits for oil producing companies. © 2022 «OilGasScientificResearchProject» Institute.
