US 10,309,184 B2 · Retrievable plugging tool for tubing

Abstract

A retrievable locking ball landing tool of the present disclosure allows for fluid circulation while running in the well. Once a plug (e.g., ball) is pumped downhole, the tool allows pressure isolation to activate hydraulic component(s) of a liner string or the like. Being retrievable, the tool eliminates the need to drill out of aluminum components once the setting operations are complete. The retrievable tool can also be used as a bridge plug to allow for wellbore isolation for a period of time. For example, the tool used as a bridge plug can be used to set a liner assembly and can suspend the well until future stimulation can be completed.

Dependent claims

An apparatus actuated by an object for isolating a zone in tubing, the apparatus comprising:

a body disposed in the tubing and having a landing engaged at least in a first longitudinal direction in the tubing, the body defining a bore with an opening permitting fluid communication through the body;
a seat disposed in the bore of the body, the seat engageable with the object and movable in the bore with the engagement from an opened condition to a closed condition relative to the opening, the seat in the closed condition closing off fluid communication through the opening regardless of the seating of the object in the seat;
and
a tool insertable in the tubing to the body, the tool disengaging the landing from the tubing in a second longitudinal direction, opposite to the first longitudinal direction, and retrieving the body and the seat together from the tubing.
