In a first scenario, nested darts provide pressure isolation between a space inside a liner assembly below an expansion cone and a well annulus. Increased pressure in this space can be used to push the expansion cone upward and assist the bottom-up expansion of a liner hanger provided at the top of the liner assembly. In a second scenario, an obstruction lands on a seat provided in a seat assembly. Pressure in a space located between the expansion cone and the seat assembly is increased such that an upward force acts on the expansion cone to expand the liner hanger. The second scenario may be utilized by itself. Alternatively, the second scenario may be utilized as a contingency method if the first scenario has failed.
