Abstract: A body (B) having a collapsed resilient element (55) therein is releasably secured on a mandrel (M). A packer (P) is supported on a packer support (26) on the mandrel. As the packer tool is assembled, opposed lugs on the mandrrel are placed in a J slot (54) of a member (25) so the packer is capable of being set by a wireline pressure setting assembly (W) when the packer tool is positioned in the opening in a tubular member or in open hole in a well bore without requiring further manipulation of the packer tool. A J slot on the member (25) cooperates with the lugs on the mandrel (M) in setting the packer tool, in releasing the packer tool and in enabling the packer tool to be readily converted for setting by a well string if desired as well as enabling the packer tool to function in many applications such as, but not limited to use as a bridge plug, production packer, test packer, treating packer, multiple string packer, seal bore packer and compression or tension well string anchor.
