Abstract

A system includes a plug and a tool. The plug is configured to perform one or more pressure tests within the tubular to determine a location of the leak. The tool includes an upper isolation packer, a lower isolation packer, a lower ball valve, an upper ball valve, and drillable tubulars. The upper isolation packer is located up hole from the location of the leak and is configured to seal against an inner surface of the tubular. The lower isolation packer is located downhole from the location of the leak and is configured to seal against the inner surface of the tubular. The lower ball valve is configured to allow the upper isolation packer and the lower isolation packer to seal against the inner surface of the tubular. The upper ball valve is configured to deploy cement into the leak to repair the leak.
