An Overview of Methods for Measuring Multiphase Flowsin Wellhead

 A multiphase flow meter is designed to measure the flow rate of two or more phases without phaseseparation.The flow meter must be accurate enough for the desired application. It must be capable to measure the specifications throughout phase fraction of each phase, independent of the flow regime. Various factors are effective on selection of the flowmeter. Moreover, various procedures are present for measurement of multi-phase flows. In this study, a comprehensive review has been implemented on various technologies in multi-phase flowmeasurement in oil industry and the basis of various measurement techniques has been investigated. The advantages, requirements, and constraints of each technology have been reviewed. Finally,the recent advances in this field have been provided for the researchers.
