Abstract: A fusible completion plug and method for its use includes a cylindrical plug body having a lower portion that includes a fusible element in communication with an electric power supply. The completion plug also includes an elastomeric seal that provides for a temporary seal. A pressure balancing port and equalization valve are provided to relieve the differential pressure across the completion plug as the plug is positioned in place. The pressure equalization valve also includes a fusible element for fusing the valve within the port, thereby preventing a leak path through the plug body. A blind flange may be installed above the completion plug in case the plug fusion fails. The blind flange may be a traditional blind flange or may be a fusible blind flange.
