Abstract
Apparatus and methods for completing a wellbore are disclosed. Certain ones of the apparatus and methods use a first packing assembly, a second packing assembly, and a pressurization assembly disposed between the first and second packing assemblies to plastically deform a liner in a radially outward direction via hydraulic pressure. Another method uses a liner having a first section and a second section, and a packing assembly. The first section is deformable in a radially outward direction at a lower pressure than the second section. The packing assembly is used to plastically deform the first section of the liner in a radially outward direction via hydraulic pressure.
