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.
