    Abstract: Provided is 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.

    Abstract: A method includes running a eutectic alloy system downhole in a wellbore including a first casing string and a second casing string therein, activating a differential valve tool within the second casing to generate a primary annular seal within a casing-casing annulus defined between the first casing string and second casing string, pumping a flushing fluid into the casing-casing annulus above the primary annular seal via a first ported collar, melting a eutectic alloy blanket into a molten alloy within the flushing fluid in the casing-casing annulus via a heater, solidifying the molten alloy to establish a supplemental seal above the primary annular seal in the casing-casing annulus between the first casing string and second casing string, and pumping cement into the casing-casing annulus above the supplemental seal to form a cement column in the casing-casing annulus via a second ported collar.
