Abstract

An explosive system is disclosed which may be used in repair of damaged casing. In a described embodiment, an explosive system includes a flexible elongated tubular container with a liquid explosive disposed within the container. As an alternative, the liquid explosive may be flowed into a wellbore without being retained within a container. The liquid explosive is detonated in the wellbore, thereby fragmenting the damaged casing and forcing it out into a formation surrounding the wellbore.
