Abstract
Embodiments of the disclosure provide a system and method for treating a casing-casing annulus of a wellbore using a sealant material. The sealant material is heated to a first temperature, equal to or greater than the melting point of the sealant material such that the sealant material is in its molten state. The casing-casing annulus is heated to a second temperature, equal to or greater than the melting point of the sealant material. The sealant material in its molten state is pressurized and injected into the casing-casing annulus such that the sealant material in its molten state occupies pore or imperfections of a cemented zone located in the casing-casing annulus. The sealant material is allowed to solidify such that formation fluids are prevented from migrating to the surface of the wellbore.
