Abstract: Wellhead chokes are special equipment that is widely used in the petroleum industry to control flow rates from wells. Two types of gas-liquid flow can exist in the choke; Critical and sub-critical flow. Field data of 29 wells producing from 3 gas condensate reservoirs located in Iran were used to develop a general Gilberttype formula obtained by nonlinear regression of data points for gas condensate wells. The present study develops a general Gilbert type formula for gascondensate wells, flowing through different choke sizes between 30/64 in. And 192/64 in Under sub-critical flow conditions in order to develop the empirical correlations to be applied to predict gas flow rates under a wide range of flow conditions that are typically encountered during the flow of gas condensates through well wells in well wells. A comparison between measured data and observed data is done with ive different errors parameters. The results of this study could be considered in the design and implementation of deliverability tests, pressure transient tests, well control, and long-term production of high rate gas condensate wells.
