Abstract

Included are wellbore sealing systems and methods of use. An example wellbore sealing system comprises a rigid sealing device capable of expansion and having an exterior having holes disposed therethrough; and an expandable sealing layer disposed around the rigid sealing device. The expandable sealing layer comprises an elastomeric layer and a reinforcing layer.

First claim

What is claimed is:

1. A wellbore sealing system comprising:
a rigid sealing device capable of expansion and having an exterior having holes disposed therethrough; and
an expandable sealing layer disposed around the rigid sealing device, the expandable sealing layer comprising:
an elastomeric layer comprising a swellable elastomer; and
an expandable reinforcing layer comprising a metal mesh selected from the group consisting of a chain link mesh, a chain mail mesh, a lock crimp mesh, a double crimp mesh, an intercrimp mesh, and any combination thereof.

2. The wellbore sealing system of claim 1 , wherein the elastomeric layer comprises a non-swellable rubber.

3. The wellbore sealing system of claim 1 , wherein the elastomeric layer is bonded to the reinforcing layer.

4. The wellbore sealing system of claim 1 , wherein the elastomeric layer is not bonded to the reinforcing layer.

5. The wellbore sealing system of claim 1 , wherein the reinforcing layer comprises a mesh comprising a material selected from the group consisting of steel, stainless steel, aluminum alloy, magnesium alloy, nickel alloy, copper alloy, titanium alloy, and any combination thereof.

6. The wellbore sealing system of claim 1 , wherein the elastomeric layer comprises an elastomeric material selected from the group consisting of ethylene propylene diene monomer rubber, nitrile butadiene, styrene butadiene, butyl rubber, polyethylene rubber, natural rubber, ethylene propylene monomer rubber, peroxide crosslinked ethylene propylene monomer rubber, sulfur crosslinked ethylene propylene monomer rubber, ethylene vinyl acetate rubber, hydrogenized acrylonitrile-butadiene rubber, acrylonitrile butadiene rubber, carboxylated acrylonitrile butadiene rubber, isoprene rubber, carboxylated hydrogenized acrylonitrile-butadiene rubber, chloroprene rubber, neoprene rubber, polynorbornene, tetrafluoroethylene/propylene, polyurethane rubber, epichlorohydrin/ethylene oxide copolymer rubber, silicone rubber, composites thereof, and any combination thereof.

7. The wellbore sealing system of claim 1 , wherein the rigid sealing device is bistable.

8. The wellbore sealing system of claim 1 , wherein the rigid sealing device is non-bistable.

9. The wellbore sealing system of claim 1 , wherein at least a portion of at least one of the elastomeric layer or the reinforcing layer is degradable.

10. The wellbore sealing system of claim 1 , wherein at least a portion of the rigid sealing device is degradable.

11. A method of forming a seal in a wellbore, the method comprising:
introducing a rigid sealing device in the wellbore; wherein the rigid sealing device has an exterior having holes disposed therethrough; wherein an expandable sealing layer is disposed around the rigid sealing device, the expandable sealing layer comprising:
an elastomeric layer comprising a swellable elastomer; and
an expandable; reinforcing layer comprising a metal mesh selected from the group consisting of a chain link mesh, a chain mail mesh, a lock crimp mesh, a double crimp mesh, an intercrimp mesh, and any combination thereof: wherein the reinforcing layer is disposed between the elastomeric layer and the exterior of the rigid sealing device;

expanding the rigid sealing device, thereby inducing expansion of the expandable sealing layer; wherein the elastomeric layer does not extrude through the holes of the exterior of the rigid sealing device; and
contacting an adjacent surface with the expandable sealing layer to form the seal.

12. The method of claim 11 , wherein the elastomeric sealing layer comprises a non-swellable rubber.

13. The method of claim 11 , wherein the rigid sealing device is bistable.

14. The method of claim 11 , wherein the rigid sealing device is non-bistable.

15. The method of claim 11 , wherein the elastomeric layer is bonded to the reinforcing layer.

16. The method of claim 11 , wherein the elastomeric layer is not bonded to the reinforcing layer.

17. The method of claim 11 , wherein the reinforcing layer comprises a mesh comprising a material selected from the group consisting of steel, stainless steel, aluminum alloy, magnesium alloy, nickel alloy, copper alloy, titanium alloy, and any combination thereof.

18. The method of claim 11 , wherein the elastomeric layer comprises an elastomeric material selected from the group consisting of ethylene propylene diene monomer rubber, nitrile butadiene, styrene butadiene, butyl rubber, polyethylene rubber, natural rubber, ethylene propylene monomer rubber, peroxide crosslinked ethylene propylene monomer rubber, sulfur crosslinked ethylene propylene monomer rubber, ethylene vinyl acetate rubber, hydrogenized acrylonitrile-butadiene rubber, acrylonitrile butadiene rubber, carboxylated acrylonitrile butadiene rubber, isoprene rubber, carboxylated hydrogenized acrylonitrile-butadiene rubber, chloroprene rubber, neoprene rubber, polynorbornene, tetrafluoroethylene/propylene, polyurethane rubber, epichlorohydrin/ethylene oxide copolymer rubber, silicone rubber, composites thereof, and any combination thereof.

19. The method of claim 11 , wherein at least a portion of at least one of the elastomeric layer or the reinforcing layer is degradable.

20. The method of claim 11 , wherein at least a portion of the rigid sealing device is degradable.
