Abstract
A well completion procedure and apparatus comprises a first assembly that includes production tubing combined with a production packer and an internal bore latching profile. A second assembly comprises an explosive perforating gun secured to a latching mechanism. The perforating gun and latching mechanism are dimensioned to freely traverse the flow bore of the production tubing for downhole retrieval and return after the packer is set. The latching mechanism may be released by discharge of the gun.
