Abstract
A method of remediation includes positioning a well tool in a bore of the first wellbore tubular, the well tool having at least one shaped charge and at least one propellant body. The method further includes detonating the shaped charge to generate a jet that forms an opening in a first wellbore tubular and a tunnel at least partially in a cement body, but does not form an opening in a second wellbore tubular. The method also includes igniting the propellant body to generate a gas at a volume and pressure selected to disintegrate the cement body.
