ABSTRACT:
A method of fabrication and the resulting structure for an economical and reliable anchor assembly to retain a conventional bridge plug within the production casing of an oil or gas well. The anchor assembly is efficiently loaded into the well and interfaced with the bridge plug via a packer and tubing, thereby eliminating the necessity of employing an expensive workover rig, which is common to many conventional well plugging techniques. The preferred method includes the step of deforming (i.e. perforating) the production casing for interlocking the anchor assembly therein. By virtue of the instant anchor assembly, a reliable plug may be installed to effectively plug back a depleted zone of an oil or gas well, while withstanding the generally large differential pressures that may be encountered at relatively deep subsurface production zones during a subsequent stimulation of the well.
