Abstract:
One example of a wellbore control tool and a method of use is described. A leak is detected in a cased wellbore comprising a multiple telescoping casing sections. A fluid flows in an uphole direction through the cased wellbore. A flow of the fluid in the uphole direction results in a first force in the uphole direction. The leak is in a first telescoping casing section. An open downhole end of a wellbore tool having a weight at least equal to a second force greater than the first force on an uphole end of a second telescoping casing section that is downhole from a location of the leak in the first telescoping casing section is seated. The open downhole end of the wellbore tool provides metal to metal contact against the uphole end of the second telescoping casing section and restricts fluid flow into the leak.
