Abstract

A packer includes a body formed from an elastic composite material having one of a one-dimensional elastic structure, a periodic elastic structure, and a random elastic structure and a filler material.

First claim

The invention claimed is:

1. A packer comprising:
a body formed from an elastic composite material having one of a one-dimensional elastic structure, a periodic elastic structure, and a random elastic structure and a filler material.

2. The packer according to claim 1 , wherein the filler material includes one or more of a carbon composite; a polymer; a metal; graphite; cotton; asbestos; and glass fibers.

3. The packer according to claim 2 , wherein the filler material comprises a carbon composite having carbon microstructures including a plurality of interstitial spaces and a binder provided in one or more of the plurality of interstitial spaces.

4. The packer according to claim 3 , wherein the binder is provided in between about 10% to about 90% of the plurality of interstitial spaces.

5. The packer according to claim 3 , wherein the carbon microstructures have a size of between about 0.1 to about 100 microns.

6. The packer according to claim 1 , wherein the filler material is one of a sintered material and a non-sintered material.

7. The packer according to claim 1 , wherein the filler material comprises between about 20% to about 97.5% of the body.

8. The packer according to claim 1 , wherein the body comprises a one-dimensional elastic structure including at least one of a solid tube, a solid rod, a coating, a powder, a plurality of pellets.

9. The packer according to claim 1 , wherein the one-dimensional elastic structure comprises a spring.

10. The packer according to claim 1 , wherein the body formed from the elastic composite material having the periodic elastic structure.

11. The packer according to claim 1 , wherein the body is supportable of pressures of at least 2000 psi (13.78 MPa) at temperatures exceeding 450° F. (232° C.).

12. A resource exploration/recovery system comprising:
a surface system; and
a downhole system including a plurality of tubulars, at least one of the plurality of tubulars including a packer comprising a body formed from an elastic composite material having one of a one-dimensional elastic structure, a periodic elastic structure, and a random elastic structure, and a filler material.

13. The resource exploration/recovery system according to claim 12 , wherein the filler material includes one or more of a carbon composite; a polymer; a metal; graphite; cotton; asbestos; and glass fibers.

14. The resource exploration/recovery system according to claim 13 , wherein the filler material comprises a carbon composite having carbon microstructures including a plurality of interstitial spaces and a binder provided in one or more of the plurality of interstitial spaces.

15. The resource exploration/recovery system according to claim 12 , wherein the filler material is one of a sintered material and a non-sintered material.

16. The resource exploration/recovery system according to claim 12 , wherein the body formed from the elastic composite material having the periodic elastic structure.

17. The resource exploration/recovery system according to claim 12 , wherein the body is supportable of pressures of at least 2000 psi (13.78 MPa) at temperatures exceeding 450° F. (232° C.).

18. A method of segregating a borehole into multiple zones comprising:
running a plurality of tubulars into the borehole; and
deploying a packer comprising a body formed from an elastic composite material having one of a one-dimensional elastic structure, a periodic elastic structure, and a random elastic structure supported by one of the plurality of tubulars.

19. The method of claim 18 , wherein deploying the packer includes expanding the packer at a portion of the borehole having a local temperature of at least 450° F. (232° C.).

20. The method of claim 18 , further comprising: exposing the packer to a pressure of at least 2000 psi (13.78 MPA).
