Using liner hangers.

Liner is a part of the casing string located at a length from the well face to the previous casing string section. Liners descent into the well on the drill string and connect to it with the help of the devices - liner hangers (disconnectors). A lot depends on the reliability of this assembly, because the elimination of an accident may take a plenty of time.
