Original Abstract Submitted
A section of casing within a wellbore is milled. After milling the section of the wellbore, the section of the wellbore is underreamed through to a next layer of casing. A setting fluid is squeezed into the section. The setting fluid penetrates micro-channels exposed by the milling and underreaming A scab liner is installed over the section. The scab liner is secured within the wellbore.
