Each completion section includes a base pipe providing an interior and defining one or more per - forations at a single axial location to provide fluid communication between the interior and an annulus defmed between the comple- tion section and a wellbore wall. One or more sand screens are radially offset from the base pipe such that a flow annulus is defmed therebetween, and a production sleeve is movably arranged within the interior of the base pipe between a closed position, where the production sleeve occludes the one or more perforations, and an open position, where the one or more perforations are exposed. A shunt system is positioned about the base pipe to receive and redirect a gravel slurry flowing in the annulus, and thereby provide an alternate flow path for the gravel slurry.
