Abstract
A downhole millable permanent plug, which permanently seals a downhole well, includes a mandrel, first and second sealing elements, a metal body, and a setting system. The mandrel has a longitudinal axis. The first sealing element is provided radially outside of the mandrel. The second sealing element is provided radially outside of the mandrel at a distance from the first sealing element. The metal body is provided radially outside of the mandrel between the first sealing element and the second sealing element. The setting system includes a heater for melting the metal body. The permanent well plug is configured to be in the following states: a run state, in which the first sealing element and the second sealing element are radially retracted; an intermediate state, in which the first sealing element and the second sealing element are radially expanded into contact with the well; and a set state, in which the metal body has been melted by the heater and subsequently solidified into contact with the well.
