Abstract
A hanger system including an expandable liner, an expandable first slip subsystem disposed about the liner, an expandable second slip subsystem disposed about the liner, a seal disposed about the liner and between the first slip subsystem and the second slip subsystem, and an expandable lock ring disposed about the liner and against one of the first slip subsystem or the second slip subsystem. A method for lining a borehole including running a liner system into a borehole, landing the liner system in a liner hanger, expanding the first slip subsystem simultaneously with a portion of the liner, expanding the second slip subsystem simultaneously with another portion of the liner, and sealing the liner to the liner hanger between the first slip subsystem and the second slip subsystem with the seal. A borehole system including a borehole in a subsurface formation, a casing in the borehole, and a liner system.
