Multi-zone sand screen with alternate path functionality

A screen assembly 312 and method of using a screen assembly 312 including an inner tubular 304, a filter screen 306, a shunt tube 318, and a perforated shroud 300. The inner tubular 304 is configured to flow a formation fluid produced at a first production zone of a formation having multiple production zones that is downhole of the screen assembly 312. The filter screen 306 is disposed radially outward from the inner tubular 304 and configured to filter a formation fluid produced at a second production zone that is proximate the screen assembly 312 prior to the formation fluid entering an annulus 308 between the filter screen 306 and the inner tubular 304. The shunt tube 318 is disposed radially outward from the filter screen 306 to flow a fluid, preferably a gravel slurry, to a location within the borehole that is downhole of the screen assembly 312. The perforated shroud 300 is disposed radially outward from the shunt tube 318. A gravel pack system having two screen assemblies 312 for use in third and fourth production zones and having a jumper tube (206, Figure 2) extending between the shunt tubes 318.
