Abstract:
1. A screen assembly for production from at least one subterranean zone, comprising: at least one screen module comprising a base pipe and a filtering assembly mounted over said base pipe to define at least one screen flow path therebetween, said filtering assembly having opposed ends extending between end connections of said base pipe; at least one coupling connected to said screen module at one of said end connections and further comprising at least one coupling flow path in flow communication with said screen flow path when said coupling is assembled to said screen module, said coupling defines an extension of said screen flow path in said filtering assembly; said base pipe and coupling, when assembled also comprising a production flow path from the subterranean zone discrete from said coupling and screen flow paths; and a valve assembly in said coupling to provide selective access between said coupling flow path and said production flow path.
