Abstract
A liner top packer is configured to be secured in a liner string, such as in a liner drilling operation. The packer is actuated from within the liner or packer body. An actuator assembly includes an inner piston, an actuator housing, and an outer piston. A tubular setting tool is moved upwardly through the inner piston, and dogs on the setting tool allow for force to be applied to the inner piston, pressurizing fluid and forcing it to the outer piston to compress a pack off element. The actuator assembly is removed by upward force applied by a foot of the setting tool on the inner piston, the actuator housing, or any other component of the actuator assembly.
