Abstract
A method of plugging a section of a wellbore wall includes sending a plug injection tool to a downhole location proximate the section of the wellbore wall, setting a first seal below the section of the wellbore wall using the plug injection tool, and setting a second seal above the section of the wellbore wall using the plug injection tool. A plugging material is pumped between the first and second seals and held there until it solidifies.
