Abstract
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 the sealant fluid. A leakage assembly in connection to the cylindrical cell assembly allows the sealant fluid to continuously flow through a leakage element 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 and transmitted to a control system including data acquisition and control units so as to monitor and measure the sealability of fluid in the downhole leakage.
