ABSTRACT:
An arrangement for lowering into a well bore casing on an operating string to sealably engage a packer that is supported on a tubular member so that the packer can be set either by a combination of hydraulic or mechanical action or mechanical action alone or hydraulic action alone includes a packer supported by a tubular member. An outer tubular member extends from adjacent the other end of the packer and telescopically receives the tubular member and a release mechanism releasably connects the tubular member and the outer tubular member with the operating string. A lock arrangement locks the tubular member and the outer tubular member together against relative longitudinal movement and the lock arrangement is operable after the release mechanism is actuated to disconnect the tubular member from the operating string whereupon said outer tubular member may be moved relative to the tubular member to expand the packer into sealing engagement with the casing.
