EXPERIMENTAL VALIDATION AND TESTING OF NON-RADIOACTIVE SOURCE MULTIPHASE METER IN HASSI MESSAOUD FIELD IN ALGERIA
A series of tests have been done to evaluate a non-radioactive multiphase flow meter (MPFM) in very high GVF conditions in Hassi Messaoud (HMD) field in Algeria, the MPFM is equipped with upstream partial separator and based on vortex meter, venturi and impedance measurements. Sixteen wells were tested and the measurements were compared to three phases test separator. It has been found that the performance of the meter is strongly related with the flow patterns. For the determination of steam component, 11 wells have gas measurement outside the accepted +/–10% accuracy band. Most wells with water content estimation of oil flow rate were outside the accepted band whereas wells without water content estimations were within the accepted +/–10% band. For water cut (WC), the absolute error for wells with stable flow and in oil continuous phase was within the accepted +/–2% band while the meter has difficulties to achieve the measurement for well with slug regime. The effects of flow slip model, dynamic of wells, flow regime, impedance technology and PVT analysis on the MPFM were analyzed and presented in this paper.
