Abstract

A deformation system, including a deformable member and a tool operatively arranged to deform the member due to actuation of the tool from a first set of dimensions at which the deformable member is positionable with respect to a structure to a second set of dimensions at which the deformable member engages with the structure. The tool at least partially comprises a disintegrable material responsive to a selected fluid. A method of operating a deformation system is also included.

Claims

1. A deformation system, comprising:

a deformable member; and

a tool operatively arranged to deform the member due to actuation of the tool from a first set of dimensions at which the deformable member is positionable with respect to a structure to a second set of dimensions at which the deformable member engages with the structure, wherein the tool at least partially comprises a disintegrable material responsive to a selected fluid.

2. The deformation system of claim 1, wherein the member is arranged to seal against the structure after deformation of the member.

3. The system of claim 2, wherein the deformable member includes a seal element.

4. The deformation system of claim 3, wherein the structure is a tubular, a casing, or a tubing radially outwardly positioned with respect to the tool and the deformable member.

5. The deformation system of claim 4, wherein the tool is a plug, and the plug and the seal element are operatively engagable together to fluidly isolate areas in the structure on opposite sides of the tool.

6. The system of claim 2, wherein the deformable member includes a gripping element for enabling the deformable member to grip the structure.

7. The system of claim 6, wherein the gripping element also seals the deformable member against the structure.

8. The deformation system of claim 1, wherein the disintegrable material comprises a plurality of metallic powder particles, each powder particle including a particle core, each particle core comprising a core material and a metallic coating layer disposed on the particle core and comprising a metallic coating material.

9. The deformation system of claim 1, wherein the disintegrable material comprises a cellular nanomatrix comprising:

a metallic nanomatrix material;

a metal matrix disposed in the cellular nanomatrix; and

a disintegration agent.

10. The system of claim 1, wherein the tool comprises at least a first material having a first rate of disintegration and a second material having a second rate of disintegration, the first and second rates of disintegration differing from each other.

11. The system of claim 10, wherein the first material is arranged as a shell and the second material is arranged as a core surrounded by the shell.

13. The system of claim 1, further comprising a ratcheting or locking feature between the tool and the member for maintaining the tool and the member in an engaged state after actuation of the tool.

14. The system of claim 1, wherein the tool is actuated by hydraulic pressure.

15. The system of claim 1, wherein the selected fluid is water, brine, oil, or a combination including at least one of the foregoing.

16. The system of claim 1, wherein the deformable member is at least temporarily secured to a support member for enabling relative movement between the tool and the deformable member during deformation.

12. The system of claim 12, wherein the first rate of disintegration is slower than that of the second rate of disintegration.

17. A method of operating a deformation system, comprising:

actuating a tool at least partially formed from a disintegrable material;

deforming a deformable member with the tool; and

disintegrating the tool upon exposure to a selected fluid.

18. The method of claim 17, wherein deforming the deformable member includes sealing the deformable member against a radially adjacent structure.

19. The method of claim 18, wherein the tool is a plug operatively engagable with the member for together isolating zones in the structure on opposite sides of the tool.

20. The method of claim 19, further comprising fracturing a selected one of the zones while the zones are isolated from each other.
