Abstract
A wellbore packer and slip combination for production tubing and the like comprises a plurality of slip elements that are caged together around the periphery of a cylindrical mandrel. An axially displaced actuator simultaneously engages all of the elements to ramp one end of all elements against a casing wall. After the one end of the slip and packer unit is set, further displacement of the actuator expands the other end of the elements against the casing wall. The packer and slip assembly may be retracted and recovered by a simultaneous lift and rotation of the tool string.
