The invention relates to a method for the formation of a plug (1) in a petroleum well (2) extending from the earth's surface or the sea floor to a petroleum reservoir, which well is lined with casing (3, 3'). At least one opening (4) is formed in the casing (3) at a distance from the earth's surface, and a liquid curable resin is provided in at least a portion of the opening (4) and an adjacent area of the well (2), whereby the resin after curing forms a plug (1) in the well. The invention also relates to a tool (9) for milling an opening (4) in a casing (3) of a petroleum well (2), and a plug (1) for plugging casing (3) of a petroleum well (2). |
