An apparatus for controlling fluid flow in a borehole, comprising: a basepipe having an interior and defining at least one first and second orifices, the at least one first and second orifices communicating the interior with the borehole; a first filter disposed on the basepipe adjacent the at least one first orifice and filtering fluid flow communicated through the at least one first orifice between the interior and the borehole; at least one first and second outflow valves disposed at the at least one first and second orifices, the at least one first and second outflow valves permitting communication of fluid flow in an outflow direction from the interior to the borehole and preventing communication of fluid flow in an inflow direction from the borehole into the interior, the at least one first outflow valve in fluid communication with the first filter; characterized by a flow device (140, 150, 160) in fluid communication with the first filter and communicating with the interior of the basepipe; a cross-over assembly operable in a first operation to communicate slurry to the borehole via a cross-over port in the basepipe and to communicate returns from the interior, wherein the at least one first outflow valve prevents communication of the returns from the first operation in the inflow direction into the interior, the flow device (140, 150, 160) permitting the returns in the inflow direction into the interior; and an isolation element (66, 68) preventing the returns communicated from the flow device (140, 150, 160) into the interior from communicating with the at least one second outflow valve at the at least one second orifice. a basepipe having an interior and defining at least one first and second orifices, the at least one first and second orifices communicating the interior with the borehole; a first filter disposed on the basepipe adjacent the at least one first orifice and filtering fluid flow communicated through the at least one first orifice between the interior and the borehole; at least one first and second outflow valves disposed at the at least one first and second orifices, the at least one first and second outflow valves permitting communication of fluid flow in an outflow direction from the interior to the borehole and preventing communication of fluid flow in an inflow direction from the borehole into the interior, the at least one first outflow valve in fluid communication with the first filter; characterized by a flow device (140, 150, 160) in fluid communication with the first filter and communicating with the interior of the basepipe; a cross-over assembly operable in a first operation to communicate slurry to the borehole via a cross-over port in the basepipe and to communicate returns from the interior, wherein the at least one first outflow valve prevents communication of the returns from the first operation in the inflow direction into the interior, the flow device (140, 150, 160) permitting the returns in the inflow direction into the interior; and an isolation element (66, 68) preventing the returns communicated from the flow device (140, 150, 160) into the interior from communicating with the at least one second outflow valve at the at least one second orifice.
