Abstract:
Wellhead chokes are special equipment that widely used in the petroleum industry to control flow rate from wells. Two types of gas–liquid flow can exist ina choke; critical and sub-critical flow. Field data of 29 wells producing from 3 gas condensate reservoir located in Iran were used to develop a general Gilberttype formula obtained by non-linear regression ofdata points for gas condensate wells. The present study develop a general Gilbert type formula for gascondensate wells, flowing through different choke sizes between 30/64 in. and 192/64 in. under subcritical flow conditions in order to developempirical correlations to be applied to predict gas flow rates under wide range of flow conditions usually encountered during the flow of gascondensates through wellhead chokes in wells. A comparison between the 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-termwell production of high rate gas condensates wells
