1. A pluggable seat, comprising:
- a first portion, positionable within a tubular, being receptive to a runnable member seatable thereagainst at a frustoconical surface thereof;
a second portion positioned downstream of the first portion, downstream being defined as a direction that the runnable member is moved into seating engagement with the pluggable seat, 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.

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.

11. A tubular actuating system, comprising:
-
a tubular; a ball being runnable within the tubular; an actuator disposed at the tubular; a seat disposed at the actuator having a first diameter smaller than the ball diameter being seatingly receptive to the ball at a frustoconical surface of a first portion thereof; and a profile disposed at a second portion of the seat having a second diameter that is smaller than the first diameter and positioned downstream of the first portion, downstream being defined as a direction that the ball is moved into seating engagement with the seat, the profile being configured to require greater pressure to extrude the ball therepast than pressure required to extrude the ball past the first portion. - View Dependent Claims (12, 13, 14)
