ABSTRACT:
There is disclosed a running tool for running and setting and then releasing from a well packer of the type having a main body and a setting sleeve vertically shiftable on the main body to set the packer. The setting tool includes a mandrel carrying a latch having left-hand threads for engaging left-hand threads on the body of the packer as well as teeth adapted to engage in notches in the upper end of the packer body to prevent right-hand rotation of the setting tool with respect to the packer as the packer is run on the setting tool into the well bore. When the packer is at the desired level, fluid pressure in the setting tool lowers the setting sleeve to set the packer and releases the setting tool from connection to the packer so that it may be retrieved.
