The present invention relates to a downhole well tool (1) for permanently sealing a downhole well (WE). The downhole well tool (1) comprises a housing (11), a first compartment (12) provided within the housing (11), an expandable sealing element (20) provided circumferentially outside a lower housing section (11b), thereby forming a second compartment (14) radially inside of the expandable sealing element (20) and radially outside of the lower housing section (11b). The tool further comprises a metal body (30) provided within the first compartment (12) and a setting system (50) comprising a heater (51) for melting the metal body (30). The tool (1) is configured to be in the following states: - a run state, in which the expandable sealing element (20) is radially retracted; - an intermediate state, in which the metal body (30) has been melted by the heater (51) and is flowing from the first compartment (12) to the second compartment (14); - a set state, in which the melted metal from the metal body (30) has been solidified within the second compartment (14).
The invention concerns a well tool (100), a well tool system (300) and a method for performing an operation in an oil/gas well. The well tool (100) comprises an orientation system (120) for longitudinal and rotational orientation of the well tool (100) when inserted into a bore (202) comprising a guide groove (203).
