Abstract
A stripper/packer for use in a stack at a well head provides horizontal actuation and side access. This configuration enables maintenance of the packer in place. It also provides for the retraction of the packer to a diameter greater than the inside diameter of the packer to permit the withdrawal of coiled tubing with accessories attached. A hydraulically actuated rod has a pusher plate attached at one end with bushings and bushing carriers attached thereto. The bushings and bushing carriers hold a packer element in abutting relation to an energizer which evenly distributes pressure from the pusher plate to the packer element. The bushings and bushing carriers also hold the packer element so that, upon retraction of the rod, the entire assembly is withdrawn from the bore of the stripper/packer.
