Abstract
A method of installing a ball seat in a wellbore, comprising conveying the ball seat via a support member of a tool to a target location in the wellbore; moving an expansion sleeve longitudinally with respect to the tool to expand the ball seat radially to engage the ball seat to a support structure of the wellbore at the target location; and releasing the support member from the engaged ball seat.
Claims15
A method of installing a ball seat in a wellbore, comprising:
- conveying the ball seat via a support member of a tool to a target location in the wellbore, the support member including a first section, a second section having fingers and a bore through the first section and the second section, a rod movable in the bore between the first section and the second section, wherein the rod prevents the fingers from collapsing radially inward when in the second section, a setting sleeve surrounding an exterior of the first section and slidable along the support member, and a support key that couples the rod to the setting sleeve through the support member;
- moving an expansion sleeve longitudinally with respect to the tool to expand the ball seat radially to engage the ball seat to a casing of the wellbore at the target location;
- and
- moving the setting sleeve along the support member to move the rod within the bore from the second section to the first section, thereby releasing the support member from the engaged ball seat.

A tool for installing a ball seat in a wellbore, comprising:
- a support member for securing the ball seat to the tool to convey the ball seat to a target location in the wellbore, the support member including a first section, a second section having fingers and a bore through the first section and the second section;
- a rod movable in the bore between the first section and the second section, wherein the rod prevents the fingers from collapsing radially inward when in the second section;
- a setting sleeve surrounding an exterior of the first section and slidable along the support member;
- a support key that couples the rod to the setting sleeve through the support member to allow the setting sleeve to move the rod within the bore;
- and
- an expansion sleeve configured to move longitudinally with respect to the tool in order to expand the ball seat to engage a support structure at the target location.
