ABSTRACT:
An expanding screen has an associated spirally wrapped exterior control line. The control line rests in a spiral trough made up in an exterior perforated jacket. The trough can be made by a pair of ridges disposed substantially parallel to each other or by an ordered spacing of raised dimples in the outer perforated jacket to create spiral troughs. At the screen connections centralizers having a spiral path or paths within can serve a dual function of locating the screen prior to expansion and protecting the control line in the joint area. A fiber optic cable can be placed in the control line.
