Abstract
A multiphase flow meter is presented based on distributed sensors that provide data pertaining to temperature, pressure, phase fraction, speed of sound, and bulk velocity. The data is provided to a model that calculates the multiphase flow rates. The sensors are comprised of various combinations of temperature and pressure sensors combined with speed of sound and/or bulk velocity sensors and are distributed at various axial positions along an oil production pipe. In one embodiment the sensors comprise Bragg grating based optical sensors.
