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 IN A 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 GILBERT TYPE FORMULA OBTAINED BY NON-LINEAR REGRESSION OF DATA POINTS FOR GAS CONDENSATE WELLS. THE PRESENT STUDY DEVELOP A GENERAL GILBERT TYPE FORMULA FOR GAS CONDENSATE WELLS, FLOWING THROUGH DIFFERENT CHOKE SIZES BETWEEN 30.64 IN. AND 192.64 IN. UNDER SUBCRITICAL FLOW CONDITIONS IN ORDER TO DEVELOP EMPIRICAL CORRELATIONS TO BE APPLIED TO PREDICT GAS FLOW RATES UNDER WIDE RANGE OF FLOW CONDITIONS USUALLY ENCOUNTERED DURING THE FLOW OF GAS CONDENSATES THROUGH WELLHEAD CHOKES IN WELLS.
A COMPARISON BETWEEN THE MEASURED DATA AND OBSERVED DATA IS DONE WITH FIVE 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 WELL PRODUCTION OF HIGH RATE GAS CONDENSATES WELLS.
