Abstract
A downhole well tool, which permanently seals a downhole well, includes a housing, a first compartment, an expandable sealing element, a metal body, a setting system, and a fluid line. The housing has an upper housing section and a lower housing section. The first compartment is provided within housing. The expandable sealing element is provided circumferentially outside the lower housing section, thereby forming a second compartment radially inside of the expandable sealing element and radially outside of the lower housing section. The metal body is provided within the first compartment. The setting system includes a heater for melting the metal body. The fluid line provides fluid communication between the first compartment and the second compartment. The well tool is configured to be in the following states: a run state, in which the expandable sealing element is radially retracted; an intermediate state, in which the metal body has been melted by the heater and is flowing from the first compartment to the second compartment; thereby expanding the expandable sealing element radially into contact with the well; and a set state, in which the melted metal from the metal body has been solidified within the second compartment.
