<p>An expandable liner hanger system (10) for forging a pressure seal and hanging of the liner weight against outer casing string (12) in a wellbore that includes an outer casing string (12), and an inner casing string (15) positioned within the outer casing string (12) and having an inner diameter. The system (10) also includes an elongate inner string tool (20) selectively insertable into the inner casing string (15) and having a torque locking sleeve (16) that removably couples with the inner casing string (15). Also included in the expandable liner hanger system (10) is an expansion cone (40) slidable along the inner string tool (20) and having a diameter greater than the inner diameter of the inner casing string (15) so that when the expansion cone (40) is urged into the inner casing string (15), the larger diameter expansion cone (40) deforms the inner casing string (15) radially outward into engagement with the outer casing string (12). The system (10) also includes a downhole hydraulic force intensified (18).</p> |
