Abstract
A method for lifting a first well tubular nested in a second well tubular from contact with the second well tubular includes moving a wellbore intervention tool to a location where the first well tubular is in contact with the second well tubular. The well intervention tool is operated to displace a wall of the first tubular until either (i) the wall of the first tubular contacts the second tubular and separates the first tubular from contact with the second tubular, or (ii) an opening is made in the wall of the first tubular. After the opening is made, an object is displaced from the wall of the first tubular until the object contact the second tubular and lifts the first tubular from the second tubular, wherein a circumferentially continuous annular space is opened between the first well tubular and the second well tubular.
