a completion tubular is placed in position adjacent the zone or zones to be fractured and produced . it features preferably sliding sleeve valves one series of which can be put in the wide open position after run in for gravel packing and fracturing zones one at a time or in any desired order . these valves are then closed and another series of valves can be opened wide but with a screen material juxtaposed in the flow passage to selectively produce from one or more fractured zones . an annular path behind the gravel is provided by an offset screen to promote flow to the screened production port . the path can be a closed annulus that comes short of the production port or goes over it . for short runs an exterior screen or shroud is eliminated for a sliding sleeve with multiple screened ports that can be opened in tandem .
