Abstract: 

Usually, multiphase flow often occurs in producing wells of gas condensate reservoirs. Different correlations were proposed for predicting pressure drop in such reservoirs. However, no correlation or model is found to predict pressure drop in a wide range of operating conditions. In this paper, pseudo spontaneous potential logging (PSP) data measured at field conditions are used to compare the performance of different correlations in predicting pressure drop and liquid holdup in four gas condensate producing wells. Measured field data from four layer wells were used to tune the vertical lift performance (VLP) correlations and best correlations were recommended from matching between measured data and tuned correlations. Finally, measured wellhead pressure and gas flow rate were used to calculate and compare bottom-hole pressure from correlations of pipesim and after-before tuned correlations of prosper with minimum error. By comparing simulation results, Gray, from pipesim software and hagedorn & brown and petroleum expert2 correlations were found most accurate correlations for gas condensate wells from prosper sftware. Results of this study open a new screening criteria for selecting the best correlations to be applied in lean gas condensate wells.
