Abstract
A method and apparatus for determining a volume of a phase of a multiphase fluid flowing in a production tubular is provided. A magnetic field is imparted on the fluid to align nuclei of the multiphase fluid along a direction of the magnetic field. A radio frequency signal is transmitted into the multiphase fluid to excite the nuclei, and a signal is detected from the nuclei responsive to the transmitted radio frequency signal. An amplitude of the detected signal is determined and the volume of the phase flowing in the production tubular is determined using the determined amplitude and an amplitude of a calibration signal.
