Abstract

A composite member for a downhole tool that includes a resilient portion; and a deformable portion having at least one groove formed therein, wherein the groove is formed in a spiral pattern, wherein the resilient portion and the deformable portion are made of a first material, and wherein a second material is bonded to the deformable portion and at least partially fills into the groove.

Claims (30)

1. A composite member for a downhole tool comprising:

a resilient portion; and

a deformable portion having at least one groove formed therein, wherein the groove is formed in a spiral pattern, wherein the resilient portion and the deformable portion are made of a first material, wherein the resilient portion comprises an angled surface, and wherein a second material is bonded to the deformable portion and at least partially fills into the groove.

2. The composite member of claim 1 , wherein the deformable portion comprises a plurality of spiral grooves formed therein.

3. The composite member of claim 2 , wherein the first material comprises one of filament wound material, fiberglass cloth wound material, and molded fiberglass composite.

4. The composite member of claim 2 , wherein each of the plurality of grooves is filled in with the second material.

5. The composite member of claim 1 , wherein the downhole tool comprises a frac plug.

6. The composite member of claim 1 , wherein the spiral pattern comprises constant pitch along an axis of the composite member.

7. The composite member of claim 1 , wherein the spiral pattern comprises varying pitch along an axis of the composite member.

8. The composite member of claim 1 , wherein the spiral pattern comprises constant pitch tilted at an angle to an axis of the composite member.

9. The composite member of claim 1 , wherein the spiral pattern comprises varying pitch tilted at an angle to an axis of the composite member.

10. The composite member of claim 1 , wherein the spiral pattern comprises constant pitch, constant radius on an outer surface of the deformable member, and wherein the spiral pattern comprises constant pitch, variable radius on an inner surface of the deformable member.

11. The composite member of claim 1 , wherein the spiral pattern comprises variable pitch, constant radius on an outer surface of the deformable portion, and wherein the spiral pattern comprises variable pitch, variable radius on an inner surface of the deformable portion.

12. A composite member for a downhole tool comprising:

a resilient portion; and

a deformable portion integral to the resilient portion and configured with a plurality of spiral grooves formed therein, wherein the deformable portion comprises a first material, and wherein a second material is formed around the deformable portion.

13. The composite member of claim 12 , wherein the composite member is made from one of filament wound material, fiberglass cloth wound material, and molded fiberglass composite.

14. The composite member of claim 13 , wherein each of the plurality of grooves are filled in with the second material.

15. The composite member of claim 14 , wherein the downhole tool is selected from a group consisting of a frac plug and a bridge plug.

16. The composite member of claim 12 , wherein the resilient portion comprises an angled surface, and wherein the second material is bonded to the deformable portion and at least partially fills into at least one of one of the plurality of grooves.

17. The composite member of claim 12 , wherein each of the spiral grooves comprises constant pitch along an axis of the composite member.

18. The composite member of claim 12 , wherein each of the spiral grooves comprises varying pitch along an axis of the composite member.

19. The composite member of claim 12 , wherein the deformable portion comprises an outer surface, an inner surface, a top edge, and a bottom edge, wherein a depth of at least one spiral groove extends from the outer surface to the inner surface, and wherein the at least one spiral groove is formed from about the bottom edge to about the top edge.

20. A downhole tool useable for isolating sections of a wellbore, the downhole tool comprising:

a mandrel;

a composite member disposed about the mandrel and in engagement with a seal element also disposed about the mandrel, wherein the composite member is made of a first material and comprises a first portion and a second portion, wherein the first portion comprises an outer surface, an inner surface, a top, and a bottom, wherein a depth of at least one spiral groove extends from the outer surface to the inner surface, and wherein the at least one spiral groove is formed between about the bottom to about the top.

21. The downhole tool of claim 20 , wherein a second material is formed around the first portion, and at least partially fills into a portion of the at least one spiral groove, and wherein the at least one spiral groove is formed with constant pitch, constant radius at an outer surface of the first portion, and wherein the at least one spiral groove is formed with constant pitch, variable radius at an inner surface of the first portion.

22. The downhole tool of claim 20 , the downhole tool further comprising a slip.

23. The downhole tool of claim 22 , the downhole tool further comprising a first cone, a bearing plate, a lower sleeve, a second slip, and a second cone.

24. The downhole tool of claim 20 , wherein a second material at least partially fills into a portion of the at least one spiral groove.
