Verification is done by flowing comparable multiphase flow through the test separator / MPFM and comparing MPFM results with (metered) volumes (of gas, oil and water) obtained downstream of the test separator. While gamma ray attenuated multiphase flow meter technology has been available for decades, only in recent years has it become relatively more widely adopted. Production Profile Prediction: Predicting flow regimes that are likely to be encountered and identification and quantification of flowing fluid properties are vital to selecting meter selection.
