Abstract

Embodiments of the disclosure pertain to a composite slip for a downhole tool, the composite slip including a circular slip body having one-piece configuration with at least two or more alternatingly arranged groove disposed therein. The circular slip body includes at least partial connectivity around the entire slip body. In aspects, one of the two or more alternatingly arranged grooves is disposed proximate to a slip end.

Claims (22)

1. A composite slip for a downhole tool, the composite slip comprising:

a circular slip body having one-piece configuration with at least two or more alternatingly arranged groove disposed therein, wherein the circular slip body comprises at least partial connectivity around the entire slip body, wherein the alternatingly arranged configuration comprises one of the two or more alternatingly arranged grooves disposed proximate to a slip end and adjacent another groove disposed proximate to an opposite slip end, wherein the groove disposed proximate the slip end extends all the way through the slip end, wherein the circular slip body comprises a first inner surface having a first angle with respect to an axis, and a second inner surface having a second angle with respect to the axis.

2. The composite slip of claim 1 , wherein the first angle is about 20 degrees, and wherein the second angle is about 40 degrees.

3. The composite slip of claim 1 , wherein the circular slip body comprises a plurality of inserts disposed therein, wherein at least one of the plurality of inserts comprises a flat surface, and wherein the circular slip body is made from filament wound material.

4. The composite slip of claim 1 , wherein the circular slip body is made from filament wound material.

5. The composite slip of claim 1 , wherein the circular slip body comprises a plurality of inserts disposed therein.

6. A composite slip for a downhole tool, the composite slip comprising:

a circular slip body having one-piece configuration with at least two or more alternatingly arranged groove disposed therein, wherein the circular slip body comprises at least partial connectivity around the entire slip body, wherein the composite slip is made from filament wound material, wherein the alternatingly arranged configuration comprises one of the two or more alternatingly arranged grooves disposed proximate to a slip end and adjacent another groove disposed proximate to an opposite slip end.

7. The composite slip of claim 6 , wherein the circular slip body comprises a plurality of inserts disposed therein.

8. The composite slip of claim 6 , wherein the groove disposed proximate the slip end extends all the way through the slip end.

9. The composite slip of claim 6 , wherein the circular slip body comprises a first inner surface having a first angle with respect to an axis, and a second inner surface having a second angle with respect to the axis.

10. The composite slip of claim 9 , wherein the first angle is about 20 degrees, and wherein the second angle is about 40 degrees.

11. The composite slip of claim 9 , wherein the circular slip body comprises a plurality of inserts disposed therein, wherein at least one of the plurality of inserts comprises a flat surface.

12. A composite slip for a downhole tool, the composite slip comprising: a circular slip body having one-piece configuration with at least two or more alternatingly arranged groove disposed therein, wherein the alternatingly arranged configuration comprises one of the two or more alternatingly arranged grooves disposed proximate to a slip end and adjacent another groove disposed proximate to an opposite slip end, wherein the circular slip body comprises at least partial connectivity around the entire slip body, wherein the groove disposed proximate the slip end extends all the way through the slip end, and wherein the circular slip body further comprises:

a first inner surface having a first angle with respect to an axis, and

a second inner surface having a second angle with respect to the axis.

13. The composite slip of claim 12 , wherein the first angle is about 20 degrees, and wherein the second angle is about 40 degrees.

14. The composite slip of claim 12 , wherein the circular slip body comprises a plurality of inserts disposed therein, wherein at least one of the plurality of inserts comprises a flat surface, and wherein the circular slip body is made from filament wound material.

15. A composite slip for a downhole tool, the composite slip comprising:

a circular slip body having one-piece configuration with at least two or more alternatingly arranged groove disposed therein, wherein the circular slip body comprises at least partial connectivity around the entire slip body, wherein the circular slip body comprises a plurality of inserts disposed therein, wherein at least one of the plurality of inserts comprises a flat surface, and wherein the circular slip body is made from filament wound material, wherein the alternatingly arranged configuration comprises one of the two or more alternatingly arranged grooves disposed proximate to a slip end and adjacent another groove disposed proximate to an opposite slip end, and wherein the groove disposed proximate the slip end extends all the way through the slip end.

16. The composite slip of claim 15 , wherein the circular slip body comprises a first inner surface having a first angle with respect to an axis, and a second inner surface having a second angle with respect to the axis.

17. The composite slip of claim 16 , wherein the first angle is about 20 degrees, and wherein the second angle is about 40 degrees.
