ABSTRACT:
A secondary plugging tool is disclosed for use in a subterranean plug, such as in a plugged and/or abandoned well. The repaired plug may be of a cementicious material, or a mechanically, hydraulically or electrically set plug or packer. The plugging tool includes an outer housing containing an eutectic metal alloy. A thermitic reaction charge is contained within chambers within an inner tubular member and a lower housing. The lower end of the outer housing being ported circumferentially there around, the thermitic reaction charge activates the eutectic metal charge such that the eutectic charge melts and pours out of the outer housing and across and upon the initial plug to repair any failure areas therein.
