ABSTRACT:
Methods and apparatus determine individual phase fractions for three phases within a fluid mixture. Appropriate flow algorithms can utilize this phase fraction information with a sensed total combined flow rate of the mixture to find individual flow rates for the three phases, such as oil, water and gas. For some embodiments, a multiphase flowmeter includes an array of spatially distributed pressure sensors configured to determine a speed of sound in the mixture and any type of water cut meter, oil cut meter or gas cut meter.
