Analog modeling of hybrid vapour extraction process

Authors: Sh.G. Rakhimova (TatNIPIneft)
Results of analog modeling of the Hybrid VAPEX process are presented by examples of heavy oils from the Ashalchinskoye and Mordovsko-Karmalskoye fields in Tatarstan. Effects of temperature, type and volume of solvent, and the method of injection of solvent and steam on oil displacement efficiency were analyzed. Efficiency of thermal reco very is substantially increased when steam is injected with solvents.
