Laboratory modelling on enchanced gas and condensate recovery

Gas condensate fields produce gradually less condensate because of retrograde condensation when pressure drops beneath the dewpoint pressure.

Gas injection counterbalances pressure drop, decreases dewpoint pressure and dilution of gas decreases condensation. Wide range of laboratory tests demonstrates the effect of gas injection on the reservoir fluid phase behaviour and the produced gas properties.
