Abstract: A downhole tool assembly for completing or cleaning a wellbore. The downhole tool assembly may include a perforation gun sub and a laser assembly sub. The perforation gun sub may be used to propagate a shockwave through one or more pre-existing perforations in a formation. The laser assembly sub may be used for treating perforations, e.g. treating the one or more pre-existing perforations. Depending on the parameters of the operation, the treating of the perforations may comprise changing the shape of the perforations and/or making the perforations wider, deeper, or otherwise adjusted.
