Abstract

A system comprises a casing; a liner that is disposed in the casing and that is 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 the liner to hang from the casing. A method for hanging the liner from the casing comprises disposing in a borehole a system comprising a casing; a liner that is 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.

First claim

What is claimed is:

1. 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 a metal alloy disposed on an inner surface of the casing thereby enabling hanging the liner from the casing; where the layer of material is an expandable metal disposed upon and in contact with a tapered surface of the liner and where the layer of material contacts the metal alloy along a circumferential surface of the layer of material.

2. The system of claim 1 , where the expandable metal forms the first bond with the liner via atomic diffusion.

3. The system of claim 2 , where the expandable metal forms the second bond with a metal alloy disposed in the casing via atomic diffusion.

4. The system of claim 1 , where the first bond and/or the second bond is a metallurgical bond.

5. The system of claim 1 , where the first bond and/or the second bond is a mechanical bond.

6. 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 a metal alloy disposed on an inner surface of the casing; where the layer of material is an expandable metal disposed upon and in contact with a tapered surface of the liner and where the layer of material contacts the metal alloy along a circumferential surface of the layer of material.
