Claim 16:
17. A method of modifying a hydrocarbon monitoring system comprising an optical flowmeter disposed at a first location in a well and a processing system, wherein a pressure of a flowing fluid at the first location is less than a bubble-point pressure of the flowing fluid and wherein the flowing fluid is a 3-phase fluid mixture at the first location, the method comprising:
introducing a sensor into the well such that the sensor is disposed at a second location in the well, wherein a pressure of the flowing fluid at the second location is greater than the bubble-point pressure of the flowing fluid; and
configuring the processing system to calculate one or more phase flow rates of the 3-phase fluid mixture, based on a first speed of sound (SoS) measurement of the flowing fluid at the first location received from the optical flowmeter, a second SoS measurement of the flowing fluid at the second location received from the sensor, and a measurement of a bulk velocity of the flowing fluid.
