A tool for penetrating a tubular as described. The tool comprises at least one length of linear shaped charge, a carrier adapted to support the/each length of linear shaped charge, and at least one detonation mechanism for detonating the/each length of linear shaped charge. Upon detonation of the/each length of linear shaped charge, a length of material is projected outwardly from the/each length of linear shaped charge towards an internal surface of die tubular, which is thereby penetrated. The at least one length of linear shaped charge is arranged such that, upon detonation, the trajectory of at least one portion of the projected material intersects the trajectory of at least one other portion of projected material at or adjacent the internal surface of the tubular.

Cutting tool

A colliding tool for severing a target in a wellbore as described. The tool comprises a housing having a first chamber, the first chamber containing an explosive charge; and an at least one detonator connected to the explosive charge, the at least one detonator being insulated from temperature in the wellbore. In use, the at least one detonator is configured to simultaneously initiate a first explosion at a first end of the explosive charge and a second explosion at a second end of said explosive charge.
