On the applicability of water-gas stimulation for Jurassic strata development

Authors: I.N. Koshovkin, A.L. Deynezhenko, A.G. Skripkin (TomskNIPIneft JSC), D.A. Anurjev (Verkhnechonskneftegaz ОJSC)
Laboratory studies of the oil displacement efficiency increase at water-gas mixture injection after oil displacement by water are executed. The core of four fields of Tomskaya Oblast was used. The displacement efficiency growth by 16-25% compared with the oil displacement by water was obtained. The method of experimental design to assess the risk of application of water-gas stimulation for oil recovery was realized.
