ABSTRACT:
A system for releasably anchoring well tools within a tubing string at a preselected downhole location. The system includes a running tool, locking mandrel, and landing nipple. Control fluid pressure is used to ensure positive engagement of the locking mandrel within the landing nipple prior to releasing the running tool from the locking mandrel. The locking mandrel and running tool are particularly useful for installation of surface controlled subsurface safety valves. However, the system can be used to install a wide variety of flow control devices and/or well tools.
