description | A method was disclosed for pulling a tubular out of a subterranean well. The method including the steps of:i) lowering a work string into the subterranean well, the work string comprising a perforating tool for perforating the tubular, and a tubular pulling tool configured to engage and pull tubulars out of the subterranean well;ii) connecting the tubular pulling tool to the tubular and apply a pulling tension to the tubular; iii) activating the perforating tool to form plurality of perforations extending from an inner wall of the tubular through a material deposited in an annulus defined between the tubular and an outer tubular 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 step iii) 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. |
