Abstract
A tool for fracturing at least one tubular is described. The tool comprises a plurality of parallel columns of explosives and a detonation system configured to detonate the columns of explosives. The columns are arranged such that upon detonation, at least a portion of the Shockwave propagating in a direction outwardly from the tool from one column combines with at least a portion of the Shockwave propagating in a direction outwardly from the tool from another column to create a combined Shockwave of greater intensity than either of the Shockwaves which formed the combined Shockwave.
