Abstract
An apparatus and method for repairing a wellbore casing (100). An opening (115) in a wellbore casing (100) is located using a logging tool (310). An expandable tubular member (370) is then positioned in opposition to the opening (115) in the wellbore casing (100). The expandable tubular member (370) is then radially expanded into intimate contact with the wellbore casing (100).
