Abstract:
A method for repairing a leak in a wellbore includes determining a location of the leak in the wellbore, lowering a casing drilling tool to approximately the location of the leak, drilling a hole in a casing lining the wellbore, pumping a sealing fluid into the hole drilled in the casing, and installing a plug in the hold in the casing.
