Popis:	The dew point pressure of a gas condensate fluid is used for planning the production profile of gas condensate reservoirs and for determining their economic success. Usually the best method of the determination of the dew point pressure loci is by visual observation when a constant mass expansion (CME) test is performed on a sample in a high-pressure cell fitted with a glass window. In this test the cell pressure is reduced in steps and the pressure at which the first sign of a liquid droplet is observed and is recorded as the dew point pressure. The gas volume of the saturated fluid at dew point pressure is used as a reference volume and the total hydrocarbon volume measured for each pressure depletion step is reported relative to this volume. For lean gas condensate systems the amount of heavy components that can condense during pressure reduction is less than 4 mol% (
