    摘要： An expandable liner hanger system for forging a pressure seal and hanging of the liner weight against outer casing string in a wellbore that includes an outer casing string, and an inner casing string positioned within the outer casing string and having an inner diameter. The system also includes an elongate inner string tool selectively insertable into the inner casing string and having a torque locking sleeve that removably couples with the inner casing string. Also included in the expandable liner hanger system is an expansion cone slidable along the inner string tool and having a diameter greater than the inner diameter of the inner casing string so that when the cone is urged into the inner casing string, the larger diameter cone deforms the inner casing string radially outward into engagement with the outer casing string. The system also includes a downhole hydraulic force intensifier.

    摘要： Disclosed herein a system comprising a casing; the casing being disposed in a borehole; a liner; the liner being disposed in the casing and being concentric with the casing; and a layer of material disposed between the liner and the casing; where the layer of material forms a first bond with the liner and a second bond with the casing thereby enabling hanging the liner from the casing. Disclosed herein too is a method comprising disposing in a borehole a system comprising a casing; the casing being disposed in a borehole; a liner; the liner being disposed in the casing and being concentric with the casing; and a layer of material disposed between the liner and the casing; heating the system at a point proximate to the layer of material; and forming a first bond between the layer of material and the liner and a second bond between the layer of material and the casing.

    摘要： Methods and apparatus include an expandable packer having a tubing expanded to create a seal in an annulus surrounding the tubing. The tubing includes a non-uniform outer surface configured to cause formation of undulations in a diameter of the tubing upon expansion of the tubing. A plurality of expandable packers may be connected to a tubular string to isolate multiple zones in a wellbore. A production tubular equipped with multiple expandable packers may be installed in the tubular string. The expandable packers may also include non-uniform outer surfaces configured to form undulations upon expansion. The combination of tubular string and production tubular may be used in an enhanced oil recovery application such as injecting steam into a formation to enhance production.
