Abstract
Screen sections have opposed open ends near the threaded connection of a base pipe and on opposed ends. The base pipes have premium threads for connection. A shroud is placed over the premium bases pipe connection that spans from one open ended screen section to another that is adjacent. Collectively a long annular space is created under the screens and alternating shrouds with access to within the base pipes provided preferably at opposed ends. The valve on one end takes returns during gravel packing and the other takes production to the surface.
