Patent ID: 7654334

Claim:
A downhole tool/running tool system for retrievably setting the downhole tool at any location within a well bore, the system comprising: a running tool comprising an inner rod, a running tool anchoring means mounted on the inner rod and controllably reconfigurable between a retracted configuration to permit movement of the tool through the well bore and a radially extended configuration for locking engagement of the running tool with the bore wall, a running tool actuating assembly for effecting reciprocal movement of the reconfiguring the running tool anchoring means to and from the retracted and expanded configurations without interacting with any restrictions or recesses within the well bore, the tool actuating assembly being moveable from a first configuration in which the tool anchoring means is retracted and a second configuration in which the tool anchoring means is expanded in response to the application of an axial force, and, a resistance means for frictionally engaging the bore wall with sufficient gripping force so as to hold the position of the running tool relative to the well bore during movement of the running tool actuating assembly to and from the first and second configuration upon application of the axial force; a downhole tool comprising a mandrel, a downhole tool anchoring means mounted on the mandrel and reconfigurable from a retracted configuration to permit movement of the downhole tool through the well bore to a radially expanded configuration for releasably engaging the cased well bore, the downhole tool anchoring means being biased towards the retracted configuration, and, a downhole tool setting means for resisting movement of the tool anchoring means from the expanded configuration back to the retracted configuration until a release mechanism is released to allow retraction of the downhole tool anchoring means and retrieval of the downhole tool from the well bore; and, means for releasably coupling the downhole tool with the running tool, said means facilitating transfer of axial loads between the running tool and downhole tool during landing and setting of the downhole tool in the well bore and arranged to release the running tool from the downhole tool upon application of an upward jarring force.
