1. A screen assembly for use in a borehole extending through a formation having multiple production zones, the screen assembly comprising:
an inner tubular for flowing a formation fluid produced at a first production zone that is downhole of the screen assembly;
a filter screen disposed radially outward from the inner tubular and configured to filter a formation fluid produced at a second production zone that is proximate the screen assembly prior to the formation fluid entering an annulus between the filter screen and the inner tubular;
a shunt tube disposed radially outward from the filter screen to flow a fluid to a location within the borehole that is downhole of the screen assembly;
a perforated shroud disposed radially outward from the shunt tube; and
wherein the formation fluid produced at the first production zone is isolated from the formation fluid produced at the second production zone within the screen assembly.
