The disclosed embodiments include methods to monitor expansion of a metallic sealant deployed in a wellbore, methods to monitor downhole fluid displacement, and downhole metallic sealant measurement systems. The method to monitor expansion of a downhole metallic sealant includes deploying a metallic sealant deployed along a section of a wellbore. The method also includes exposing the metallic sealant to a reacting fluid to initiate a galvanic reaction. The method further includes measuring a change in temperature caused by the galvanic reaction. The method further includes determining an amount of expansion of the metallic sealant based on the change in the temperature.

A method and apparatus for determining the sealability of an oil & gas well sealant fluid, whereby a cylindrical cell assembly capable of withstanding high temperature and high pressure with an electromagnetic heater positioned radially outside the cell body while partly filled with said sealant fluid. A minor-leak assembly in connection to said cylindrical cell assembly allows said sealant fluid to continuously flow through a leak sample at a desired differential pressure, and the residual fluid is drained into said cell by a cycling pipeline system. The real-time pressure may be recorded to transmitted to a control system comprised of data acquisition and control units so as to monitor and measure the sealability of fluid in the downhole minor leaks.

A test system for a pressure control equipment (PCE) stack includes a pump for directing fluid into the PCE stack, a drive for operating the pump to control fluid flow into the PCE stack, and a controller communicatively coupled to the drive and a sensor that transmits sensor data indicative of pressure within the PCE stack. The controller instructs the drive to cause the pump to direct fluid into the PCE stack until the sensor data indicates that the pressure within the PCE stack has reached a threshold pressure, blocks fluid flow into and out of the PCE stack upon receiving sensor data indicating the pressure within the PCE stack has reached the threshold pressure, monitors the pressure within the PCE stack over a time interval, and determines a condition of the PCE stack based on a change in the pressure within the PCE stack during the time interval.
