A seal bore packer comprising a packer subassembly which can be employed with either wireline or tubing manipulatable packer setting subassemblies is disclosed. Packing elements and slips on a packer subassembly are expanded when relative axial forces are applied to the packer by wireline or mechanical setting forces. The packer has an inner mandrel and intermediate mandrel connected by a shear pin. A collapsible ring holds the outer packer assembly, including slips and packing elements, normally secured to the intermediate mandrel. Relative movement between the intermediate mandrel and the inner mandrel releases the packer.
