First Claim
1. A method of using a liner hanger, the liner hanger including a tubular body, the tubular body including a first end, a second end, an expandable pipe and a launcher chamber located longitudinally between the first end and the expandable pipe, wherein the first end includes a connection to a liner, and wherein the expandable pipe has a first inner diameter and the launcher chamber has a second inner diameter that is larger than the first inner diameter, the method comprising:
- inserting an adjustable cone of an expansion tool through the expandable pipe into the launcher chamber, the adjustable cone being in a retracted configuration wherein an outer diameter of the adjustable cone is less than the first inner diameter;

Abstract
A liner hanger is used for deploying a liner into a wellbore. The liner hanger includes a tubular body having a first end and a second end. The first end can include a connection to a liner. The second end can include a sealed connection to an operational pipe. The sealed connection can be releasable. An expansion tool attached to a work string can be used for suspending the liner hanger into the wellbore. At least a portion of the expandable pipe is radially expanded using the expansion tool. The radial expansion of the expandable pipe can cause compression of at least one seal member against a base casing.
