Abstract

A pluggable seat includes, a first portion, positionable within a tubular, that is receptive to a runnable member seatable thereagainst, a second portion positioned downstream of the first portion, having a radial dimension smaller than a smallest radial dimension of the first portion, and a profile disposed at the second portion configured to increase resistance to extrusion of a runnable member past the pluggable seat in comparison to the same pluggable seat without the profile.

Claims

1. A pluggable seat, comprising:

a first portion, positionable within a tubular, being receptive to a runnable member seatable thereagainst;

a second portion positioned downstream of the first portion, having a radial dimension smaller than a smallest radial dimension of the first portion; and

a profile disposed at the second portion configured to increase resistance to extrusion of a runnable member past the pluggable seat in comparison to the same pluggable seat without the profile.

2. The pluggable seat of claim 1, wherein the profile includes at least one tooth that extends upstream of a portion of the pluggable seat having a larger radial dimension than a radial dimension of the at least one tooth.

3. The pluggable seat of claim 2, wherein the at least one tooth has a rake angle between zero and ninety degrees.

4. The pluggable seat of claim 1, further comprising a constant dimensioned portion disposed between the first portion and the second portion.

5. The pluggable seat of claim 1, wherein the profile includes a chamfer.

6. The pluggable seat of claim 1, wherein the runnable member is a ball.

7. The pluggable seat of claim 1, wherein the radial dimension is a radius.

8. The pluggable seat of claim 1, wherein the profile includes a knurl.

9. The pluggable seat of claim 1, wherein the profile includes serrations.

10. The pluggable seat of claim 1, wherein the profile includes a plurality of buttresses.

11. The pluggable seat of claim 1, wherein the profile includes a material attached thereto configured to increase friction between the runnable member and the profile.

12. A pluggable seat retainer enhancement mechanism comprising a profile on a downstream portion of a pluggable seat configured to increase extrusion forces of a runnable member seatable thereagainst.

13. A tubular actuating system, comprising:

a tubular;

a ball having a ball diameter being runnable within the tubular;

an actuator disposed at the tubular;

a seat disposed at the actuator having a minimum diameter smaller than the ball diameter being receptive to the ball; and

a profile disposed at the seat having dimensions no smaller than the minimum diameter configured to increase pressure needed to extrude the ball past the seat.

14. The tubular actuating system of claim 13, wherein the ball is deformable.

15. The tubular actuating system of claim 13, wherein the profile includes a tooth having a rake angle between zero and ninety degrees.

16. The tubular actuating system of claim 13, wherein the profile includes a material attached to the seat that has a greater coefficient of friction with the ball than the material of the seat.

17. The tubular actuating system of claim 13, wherein the profile includes one of, knurls, serrations and buttresses.
