Abstract

A debris catcher can include an anchor connected to the wellbore tubular and a filter fixed to the anchor. The filter is positioned in a bore of the wellbore tubular and has an disintegrable accelerator material located in a carrier body. The debris catcher formed at least partially of a disintegrable accelerator material located in a carrier body is conveyed in a wellbore tubular. The disintegrable accelerator material is exposed to a downhole material in a subterranean fluid flowing through the wellbore tubular. The debris catcher filters the downhole material. It is emphasized that this abstract is provided to comply with the rules requiring an abstract, which will allow a searcher or other reader to quickly ascertain the general subject matter of the technical disclosure.

Claims (24)

1. A debris catcher for performing a downhole operation in a wellbore tubular, comprising:

an anchor connected to the wellbore tubular; and

a filter fixed to the anchor and positioned in a bore of the wellbore tubular, wherein the filter comprises a disintegrable accelerator material located in a carrier body, the disintegrable accelerator material being selected to disintegrate a material received in the filter.

2. The apparatus of claim 1 , wherein the disintegrable accelerator material has at least one of: (i) copper, (ii) silver, (iii) tin, (iv) nickel, (v) the alloys thereof, (vi) acids, and (vii) brines.

3. The apparatus of claim 1 , wherein the carrier body comprises a sealed capsule.

4. The apparatus of claim 1 , wherein the sealed capsule has at least one of (i) a degradable material, and (ii) a frangible shell.

5. The apparatus of claim 1 , wherein the filter comprises a plurality of carrier bodies each with a varying rate of disposition in response to different stimuli.

6. The apparatus of claim 1 , wherein the filter comprises a plurality of carrier bodies each with a different composition of the disintegrable accelerator material.

7. The apparatus of claim 1 , wherein the disintegrable accelerator material is configured to interact with a degradable downhole material.

8. The apparatus of claim 7 , wherein the interaction is a chemical interaction when the disintegrable accelerator material and the degradable downhole material come into contact.

9. The apparatus of claim 1 , wherein the filter comprises an energetic material located in the carrier body.

10. The apparatus of claim 9 , wherein the energetic material comprises at least one of: (i) thermite, (ii) nano-foil, and (iii) nano-aluminum.

11. The apparatus of claim 9 , wherein the energetic material comprises a trigger response member comprising at least one of: (i) an electrical mechanism (ii) a magnetic field mechanism, (iii) a microwave mechanism, (iv) a high energy beam mechanism, and (v) a radio frequency mechanism.

12. The apparatus of claim 1 , wherein the disintegrable accelerator material is selected to only decompose chemically and wherein the carrier body is selected to structurally destabilize by one of: (i) mechanically, (ii) thermally, and (iii) chemically.

13. A method for performing a downhole operation in a wellbore tubular, comprising:

conveying a debris catcher formed at least partially of a disintegrable accelerator material located in a carrier body;

filtering a downhole material using the debris catcher, the downhole material being in a subterranean fluid flowing through the wellbore tubular;

exposing the disintegrable accelerator material;

initiating a functionally intended chemical reaction between the disintegrable accelerator material and the downhole material; and

degrading the downhole material received in the debris catcher.

14. The method of claim 13 , further comprising releasing the disintegrable accelerator material including at least one of: (i) mechanically breaking the carrier body, (ii) chemically dissolving the carrier body, and (iii) electrically igniting an energetic material located in the carrier body, and (iv) thermally igniting an energetic material located in the carrier body.

15. The method of claim 13 , further comprising sending a trigger into the wellbore tubular and activating an energetic material located in the carrier body.

16. The method of claim 13 , further comprising sending a trigger into the wellbore and activating a trigger member located in the debris catcher.

17. The method of claim 13 , wherein the disintegrable accelerator material interacts only chemically with the downhole material in the debris catcher, and further comprising: structurally destabilizing the carrier body by one of: (i) mechanically, (ii) thermally, and (iii) chemically.
