Abstract
A tool string having a pressure dependent mandrel and actuator assembly can operate at the annulus pressure within a wellbore to lock the mandrel actuator assembly and prevent further motion of the mandrel within the tool string as the tool string is moved upward or downward in the wellbore. The tool string can further include a valve connected to the actuator assembly, where the valve can be in an open configuration within the wellbore due to the annulus pressure and related motion of the mandrel, and then be locked in an open configuration regardless of the annulus pressure as the tool string is moved upward or downward in the wellbore.
