Abstract
A downhole tool comprises a heater including a container enclosing a volume of compacted thermite. A volume of flowable alloy is provided above the heater. A fusible bulkhead may be provided between the heater and the alloy and provides for direct conduction of heat from the heater to the alloy. A housing containing the alloy may be separated from the heater by heating a fusible socket that anchors an end of a tensioned support member. The thermite may define an internal volume adapted to receive alloy. The heater may be activated to melt the alloy and the alloy may then solidify to form a bore-sealing plug.
