    Abstract

    Conventional phase behaviour laboratory tests on gas condensate fluids are commonly limited to measuring pressure-volume data. In constant volume depletion tests, the produced gas is analysed after flashing it to atmospheric conditions and the condensate properties are determined by material balance. Modifications on a conventional gas condensate equilibrium cell have been made and presented in this paper which allow direct measurement of density and compositions of gas and condensate phases. The proposed method can be applied to all types of phase behaviour tests including constant composition studies. Accurate determination of the interfacial tension of gas-condensate systems is of significant value as surface forces play a major role in condensate-recovery. A method based on the liquid-gas interface curvature is proposed to measure the gas-condensate interfacial tension along with other properties with a minimum effort. The interfacial tension values measured by the above method have been compared with literature data and their reliability demonstrated.
