Cone for a downhole tool
A downhole tool for use in a wellbore includes a cone, a cone adapter at least partially disposed in the cone, a shoe member, and a slip assembly disposed between the cone and the shoe member. A mandrel extends through the cone adapter and attached to the shoe member. The cone adapter is retrievable with the mandrel.
1. A downhole tool, comprising:
a cone having a cone shaped bore;
a cone adapter at least partially disposed in the cone, the cone adapter having a cone shaped outer surface complementary to and configured to support the cone shaped bore of the cone;
a shoe member;
a slip assembly disposed between the cone and the shoe member;
a mandrel extending through the cone adapter and attached to the shoe member, wherein the cone adapter is retrievable with the mandrel.
2. The downhole tool of claim 1 , wherein the cone adapter includes a shoulder disposed between the cone and a setting tool for setting the slip assembly.
3. The downhole tool of claim 1 , wherein a majority portion of the cone has a thickness from 0.3 in. to 1 in.
4. The downhole tool of claim 3 , wherein the cone has two different thicknesses.
5. The downhole tool of claim 1 , wherein a thickness of the cone at an upper end of the cone is thinner than a thickness of the cone adapter at the same axial location.
6. The downhole tool of claim 1 , wherein the cone adapter includes a mandrel bore for accommodating the mandrel, wherein the mandrel bore extends through the cone adapter.
7. The downhole tool of claim 6 , wherein the mandrel includes a shoulder disposed in a recessed section of the mandrel bore of the cone adapter.
8. The downhole tool of claim 1 , wherein the shoe member is releasably attached to the mandrel.
9. The downhole tool of claim 1 , further comprising a seal assembly.
10. The downhole tool of claim 1 , wherein the slip assembly includes a plurality of slip segments.
11. The downhole tool of claim 1 , wherein the slip assembly is at least partially disposed on an incline of the cone.
12. A method of performing a wellbore operation, comprising:
deploying a downhole tool into a wellbore using a setting tool, the downhole tool including:
a cone supported by a cone adapter, the cone includes a cone shape bore and the cone adapter includes a cone shaped outer surface complementary to the cone shaped bore;
a slip assembly; and
a mandrel extending through the cone adapter and releasaby attached to a shoe member;
using the setting tool to engage the slip assembly with a downhole surface;
detaching the mandrel from the shoe member; and
moving the cone adapter away from the cone by retrieving the mandrel.
13. The method of claim 12 , wherein the downhole tool further includes a seal assembly, and the method includes contacting the seal assembly with the downhole surface.
14. The method of claim 12 , the method includes moving a shoulder of the mandrel along a recessed section of a mandrel bore of the cone adapter.
15. The method of claim 14 , further comprising abutting the shoulder of the mandrel with an end of the recessed section.
16. The method of claim 12 , wherein engaging the slip assembly causing expansion of at least a portion of the cone.
17. The method of claim 12 , further comprising performing a fracturing operation.
18. The method of claim 16 , wherein detaching the mandrel from the shoe member includes shearing away a portion of the shoe member.
19. A downhole tool, comprising:
a cone;
a cone adapter at least partially disposed in the cone, the cone adapter includes a mandrel bore extending through the cone adapter for accommodating a mandrel;
a shoe member;
a slip assembly disposed between the cone and the shoe member;
the mandrel extending through the cone adapter and attached to the shoe member, the mandrel includes a shoulder disposed in a recessed section of the mandrel bore of the cone adapter, wherein the cone adapter is retrievable with the mandrel.
