Abstract

A downhole tool suitable for use in a wellbore, the tool having a double cone having a dual-cone outer surface. The downhole tool includes a carrier ring disposed around one end of the double cone, and a slip disposed around or proximate to an other end of the double cone. There is a guide assembly engaged with the slip.

Claims (56)

1. A downhole tool for use in a wellbore, the downhole tool comprising:

a double cone comprising:

a distal end; a proximate end; an outer surface; an inner flowbore disposed in the double cone, and extending therethrough from the proximate end to the distal end;

and a ball seat formed within the inner flowbore;

a carrier ring slidingly engaged with the proximate end, the carrier ring further comprising an annular outer seal element groove;

a slip engaged with the distal end; and

a guide assembly proximate the slip,

wherein the outer surface comprises a first angled surface and a second angled surface,

wherein a seal element is disposed in the annular outer seal element groove,

wherein the first angled surface comprises a first plane that in cross section bisects a longitudinal axis a first angle,

wherein the second angled surface comprises a second plane that in cross section bisects the longitudinal axis at a second angle negative to that of the first angle,

wherein in a set configuration, the carrier ring comprises an underside surface entirely in contact with the outer surface, and a ball is engaged against the ball seat.

2. The downhole tool of claim 1 , wherein the first angle is in a first angle range of 5 degrees to 10 degrees, wherein the second angled is in a second angle range of 5 degrees to 40 degrees, and wherein the ball seat is defined by the inner flowbore having a first inner diameter smaller than a second inner diameter.

3. The downhole tool of claim 2 , wherein the slip comprises an at least one slip groove that forms a lateral opening in the slip that is defined by a depth that extends from a slip outer surface to a slip inner surface, wherein the opening is void of material at a first slip end, and wherein the slip comprises an at least one insert.

4. The downhole tool of claim 3 , wherein any component of the downhole tool is made of a dissolvable composite material.

5. The downhole tool of claim 3 , wherein the carrier ring is configured to elongate by no more than 20% with respect to its original shape without fracturing, and wherein the inner flowbore comprises an inner diameter in a bore range of 0.5 inches to 5 inches.

6. The downhole tool of claim 5 , wherein the guide assembly comprises shear threads, and wherein the seal element is not engaged by a cone.

7. The downhole tool of claim 6 , wherein a longitudinal length of the downhole tool in the set configuration is in a set length range of about 5 inches to about 20 inches.

8. The downhole tool of claim 1 , wherein when the ball is seated on the ball seat, the ball is not in contact with any other component of the downhole tool.

9. A downhole setting system for use in a wellbore, the system comprising:

a workstring;

a setting tool assembly coupled to the workstring, the setting tool assembly further comprising:

a tension mandrel comprising a first tension mandrel end and a second tension mandrel end; and

a setting sleeve;

a downhole tool comprising:

a double cone comprising:

a distal end; a proximate end; an outer surface; an inner flowbore disposed in the double cone, and extending therethrough from the proximate end to the distal end; and a ball seat formed within the inner flowbore;

a carrier ring slidingly engaged with the proximate end;

a slip engaged with the distal end; and

a guide assembly proximate the slip,

wherein the tension mandrel is disposed through the downhole tool, wherein a nose nut is engaged with the second tension mandrel end,

wherein the outer surface comprises a first angled surface and a second angled surface,

wherein the first angled surface comprises a first plane that in cross section bisects a longitudinal axis a first angle,

wherein the second angled surface comprises a second plane that in cross section bisects the longitudinal axis at a second angle negative to that of the first angle,

wherein the ball seat is defined by the inner flowbore having a first inner diameter smaller than a second inner diameter, and

wherein in a set configuration, the carrier ring comprises an underside surface entirely in contact with the outer surface, and a ball is engaged against the ball seat.

10. The downhole setting system of claim 9 , wherein the first angle is in a first angle range of 5 degrees to 10 degrees.

11. The downhole setting system of claim 10 , wherein the carrier ring is configured to elongate upward to 20% with respect to its original shape without fracturing.

12. The downhole setting system of claim 11 , wherein the inner flowbore of the double cone comprises an inner diameter in a bore range of 1 inch to 6 inches.

13. The downhole setting system of claim 12 , wherein a longitudinal length of the downhole tool in the set configuration is in a set length range of at least 5 inches to no more than 20 inches.

14. The downhole setting system of claim 9 , wherein the slip comprises an at least one slip groove that forms a lateral opening in the slip that is defined by a depth that extends from a slip outer surface to a slip inner surface.

15. The downhole setting system of claim 14 , wherein the slip comprises an at least one hollowed insert.

16. The downhole tool of claim 9 , wherein when the ball is seated on the ball seat, the ball is not in contact with any other component of the downhole tool.

17. A downhole tool for use in a wellbore, the downhole tool comprising:

a double cone comprising:

a distal end; a proximate end; an outer surface; an inner flowbore disposed in the double cone, and extending therethrough from the proximate end to the distal end;

and a ball seat formed within the inner flowbore;

a carrier ring slidingly engaged with the proximate end, the carrier ring further comprising an annular outer seal element groove;

a slip engaged with the distal end; and

a guide assembly proximate the slip,

wherein the outer surface comprises a first angled surface and a second angled surface,

wherein a seal element is disposed in the annular outer seal element groove,

wherein in a set configuration, the carrier ring comprises an underside surface entirely in contact with the outer surface, and a ball is engaged against the ball seat,

wherein the first angled surface comprises a first plane that in cross section bisects a longitudinal axis a first angle in a first angle range of 5 degrees to 10 degrees,

wherein the second angled surface comprises a second plane that in cross section bisects the longitudinal axis at a second angle negative to that of the first angle and in a second angle range of 5 degrees to 40 degrees, and

wherein the ball seat is defined by the inner flowbore having a first inner diameter smaller than a second inner diameter.
