Abstract
A method and a device for in situ formation of a seal () in a region () of an annulus () located around a pipe structure () in a well (), in which the method comprises the following steps: (A) to convey a perforation device into the pipe structure () to a location vis-a-vis said region () of the annulus (); (B) by means of the perforation device, to make at least one hole () through the pipe wall of the pipe structure () at said annulus region (); (C) to force a liquid sealing material, which is capable of entering into solid state, through said hole () and further into the annulus region () for the filling thereof, where-upon the sealing material enters into solid state and forms said seal (). The distinctive characteristic of the method is that step (C) thereof also comprises:—to choose a fusible, solid-state packer material () as raw material for said seal material;—to heat and melt at least a part of the solid-state packer material (); and—subsequently, to force liquid packer material () into the annulus region () via the at least one hole () through said pipe wall, whereupon the liquid packer material () enters into solid state and forms said seal () in the annulus region ().
