Expandable seals have one or more conforming ribs to facilitate creation of a seal to a sealing surface disposed in the well. The conforming ribs comprise a core of material either capped, partially covered by, or entirely covered by a ring. The ring can be formed of a metal that is softer than the metallic core material of each rib. Suitable metals forming the rings include copper formed by metal spun methods. Disposed adjacent to the rings are one or more sealing elements. By moving the rings into the sealing surface during expansion of the expandable seals, the rings close the extrusion gaps between the internal surface of the casing and the expanded tubular member ribs. The rings better conform to the sealing surface of the casing, thereby facilitating the creation of the seal between this sealing surface and each of the sealing elements.

1. A sealing device for an expandable tubular, the sealing device comprising: a tubular member having an outer wall surface and a bore defined by an inner wall surface;a first rib disposed on the outer wall surface, the first rib comprising a first metallic core material providing a first rib outer diameter surface; anda first metallic conforming material disposed on at least a portion of the first rib outer diameter surface, the first metallic conforming material being more malleable compared to the first metallic core material. 2. The sealing device of claim 1, wherein the first metallic conforming material partially covers a first side of the first rib. 3. The sealing device of claim 2, wherein the first metallic conforming material completely covers the first rib. 4. The sealing device of claim 1, wherein the first metallic conforming material comprises copper. 5. The sealing device of claim 1, further comprising: a second rib, the second rib comprising a second metallic core material providing a second rib outer diameter surface and a second metallic conforming material disposed on at least a portion of the second rib outer diameter surface, the second metallic conforming material being more malleable compared to the second metallic core material. 6. The sealing device of claim 5, wherein the second metallic conforming material partially covers a first side of the second rib. 7. The sealing device of claim 6, wherein the second metallic conforming material completely covers the second rib. 8. The sealing device of claim 5, wherein the first metallic conforming material partially covers a first side of the first rib. 9. The sealing device of claim 8, wherein the first metallic conforming material completely covers the first rib. 10. The sealing device of claim 5, wherein the first metallic conforming material completely covers the first rib and the second metallic conforming material completely covers the second rib. 11. The sealing device of claim 5, wherein the first metallic conforming material and the second metallic conforming material comprise copper. 12. An expandable tubular for disposition within a wellbore, the expandable tubular comprising: a radially expandable body having an outer wall surface, the body comprising a metallic core material;a first metallic conforming material disposed on the outer wall surface, the first metallic conforming material engaging a sealing surface when the body is radially expanded, the first metallic conforming material being more malleable as compared to the metallic core material. 13. The expandable tubular of claim 12, wherein the first metallic conforming material is disposed on an outer diameter surface of a first rib, the first rib being disposed on the outer wall surface of the body. 14. The expandable tubular of claim 12, wherein the first metallic conforming material forms a first ring disposed around the outer wall surface of the body. 15. The expandable tubular of claim 14, wherein the first ring is disposed over a first rib, the first rib being disposed on the outer wall surface of the body. 16. The expandable tubular of claim 15, wherein the first ring completely covers the rib. 17. The expandable tubular of claim 12, further comprising a second metallic conforming material disposed on the outer wall surface. 18. The expandable tubular of claim 17, wherein the second metallic conforming material is disposed on an outer diameter surface of a second rib, the second rib being disposed on the outer wall surface of the body. 19. A method of sealing an annulus of a wellbore, the method comprising the steps of: (a) running a tubular member into a wellbore defined by an inner wall surface, the tubular member having an outer wall surface and a sealing device disposed on the outer wall surface, the sealing device comprising a metallic core material and a metallic conforming material, the metallic conforming material being more malleable compared to the metallic core material, the metallic conforming material being disposed over a portion of the metallic core material on an outer wall surface of the sealing device;(b) applying a radial load to expand the tubular member causing the metallic conforming material to engage the inner wall surface of the wellbore; and(c) continuing to apply the radial load causing the metallic conforming material to change shape in conformance with the shape of the inner wall surface of the wellbore, thereby creating a seal between the inner wall surface of the wellbore and the sealing device. 20. The method of claim 19, wherein the metallic core material is disposed on a rib, the rib being disposed on the outer wall surface of the tubular member, and wherein during step (c), the rib transfers the radial load to the metallic conforming material.
