In this investigation some widely used correlations for gascondensate PVT properties were subjected to validation test, and were found to be inadequate for prediction of condensate down-hole PVT properties below the saturation pressure. The error margins associated with the use of some of these correlations for predicting condensate compressibility factor, density and viscosity were at levels unacceptable for engineering calculations. The new correlations include Eqs. (1), (4) and (22) for condensate compressibility factor, density and viscosity respectively. The modified correlations were tested and validated against large experimental measured database. The results showed a superior performance of the modified to the existing correlations in comparison with measured database. The novelty of this investigation is the demystification of the perplexing fluid PVT properties phase behaviour which is a barrier to accurate well deliverability modelling in gas condensate reservoirs.
