The torch and/or cutting apparatus comprises a body having a nozzle adapted to project a fuel load, such as molten thermite or molten thermite with a polymer, in a direction aligned with the obstruction. The adapter comprises protruding elements for eliminating or diminishing damage to the area surrounding the obstruction, including the inner walls of the wellbore and/or casing, and can further comprise centralizers for alignment of the apparatus with the obstruction, within the wellbore.
