Description
Summary:At present, it is becoming more relevant to use other displacing agents, which are more effective in comparison with waterflooding, for increasing oil and gas condensate deposits component recovery. One of such promising methods is simultaneous water and gas injection. In this article, we present the principal options for using simultaneous water and gas injection in Arctic fields, case study of the Urengoyskoye and Prirazlomnoye fields. Technological schemes for its implementation in the Urengoyskoye field at low reservoir pressures are considered. Filtration studies of oil from reservoir models with water-gas mixtures at various gas contents allow increasing hydrocarbon recovery efficiency by determining the area of rational gas contents. For the conditions of the Prirazlomnoye field, the possibility of using pump-ejector system for the utilization of associated petroleum gas has been established. © Published under licence by IOP Publishing Ltd.
