Abstract
Method and apparatus for melting a material and squeezing the melted material through casing perforations into a fault within the cement or formation of an oil or gas well. A heating tool carries solid material which is melted at depth within the well and adjacent to the casing perforations. The liquefied material is forced through the perforations and into the formation or the well cement. When the material cools and solidifies, the faults become sealed.
