Abstract
A method for the determination of the water cut and volumetric flow rate of a fluid flowing through a density inflow control valve. A density inflow control valve may include a floating device that moves between a relaxed choke position and a restricted choke position depending on the density of the fluid flowing through the valve. Pressure gauges upstream and downstream of the inflow control device may be used to measure the pressure drop across the inflow control valve over time. The water cut of the downhole fluid flowing through the valve may be determined from the pressure drop over time and the pressure drop associated with the relaxed choke position and the restricted choke position. The volumetric flow rate may be determined from the average water cut and the density of the downhole fluid, as determined from the single phase densities.
