Claim Text:
1. A system for determining densities and proportions of phases in a multi-phase fluid flow (MFF) that can include an oil phase, a water phase, and a gas phase from a well, the system including: a first density sensor that senses, in real time, a plurality of first density profiles of the MFF at a first location where phases of the MFF are separated for, at least, short intervals of time; a second density sensor that senses a plurality of second density profiles of the MFF at a second location where the MFF is a blended mixture of, at least, the oil phase, the water phase, and the gas phase; a third density sensor that senses, in real time, a plurality of third density profiles of the MFF at a third location where the gas phase is separate from a mixed liquid portion of the MFF that includes, at least, the water phase and the oil phase; and one or more processors for executing one or more programs to determine a density of the oil phase, a density of the water phase, a density of the gas phase, and proportions of phases including a water cut and a gas volume fraction based on at least the plurality of first, second, and third density profiles.
