NUMERICAL MODELLING OF WATER-GAS INJECTIONINTO A GAS CONDENSATE RESERVOIR AT THE FINAL STAGE OFDEVELOPMENT

Based on a three-phase, multicomponent fluid filtration model, a simulation was performed for the process of displacing a gas condensate mixture using water with an added gas phase.This approach allows for the consideration of all occurring physicochemical processes.On this basis, the potential for increasing condensate recovery from the reservoir during the final stage of development through water-gas injection has been investigated.
