A downhole tool and a running tool for retrievably setting a downhole tool at locations within a well bore

-38 Abstract A rur ning tool for landing and setting a retrievable downhole tool at any 5 locati n in a well bore includes an inner rod, a running tool anchoring device mounted on the inner rod and controllably r configurable between a retracted configuration to permit movement of the tool through the well bore and a radial y extended configuration for locking engagement of the running tool with the bore wall, a running tool actuating assembly for effecting reciprocal 10 move ent of the reconfiguring the running tool anchoring device to and from the retracted and expanded configurations without interacting with any restri tions or recesses within the well bore, and a resistance device for frictio ally engaging the bore wall with sufficient gripping force so as to hold the p sition of the running tool relative to the well bore during movement of 15 the running tool actuating assembly to and from the first and second configuration upon application of the axial force. 1 of 13 - 300 21-0 -12 -0 S42 102 19 100 23-- -23 46 -2 \ 783- --- 03 b 1047
