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.

Retrievable plugging tool for tubing

An apparatus for supporting tubing in casing includes a setting tool and a liner top packer, which can be used for tieback. A setting slip is disposed uphole of a packing assembly on the packer and is movable from a retracted to an extended state engaging the casing. The setting tool has a temporary connection to the packer and has a pack-off that seals the tool in the packer but allows for movement. After running downhole, the temporary connection of the setting tool to the packer is disconnected, and the setting slip is set in the casing by moving the setting tool in an uphole direction. To set the packing assembly, the packer is moved in the uphole direction by engaging the setting tool with the pack-off and compressing the packing element (e.g., packing element and opposing cones and slips) against the set setting slip. Eventually, the setting tool is disconnected from the packer by disengaging the pack-off.
