Zusammenfassung:A method for pulling a tubular out of a subterranean well including the steps of:i) lowering a work string into the well which includes a perforating tool and a tubular pulling tool;ii) connecting the tubular pulling tool to the tubular and apply a pulling tension to the tubular;iii) activating the perforating while the applied pulling tension to the tubular is maintained;iv) immediately upon activating the perforating tool and while maintaining pulling tension to the tubular, pulling the tubular on the work string out of the subterranean well;wherein a cut in the tubular is formed prior to or simultaneously with step iii); and wherein the cut is arranged such that the tubular can be pulled out of the subterranean well during step iv).Further, a system for pulling a tubular was also disclosed.
