A well screen having an internal, blank alternate flowpath for delivering fracturing fluid/gravel slurry to different levels within a well annulus. The well screen includes an outer pipe which is positioned over a base pipe thereby forming an annulus therebetween. The circumference of each pipe has a perforated sector and a blank sector, both of which extend along their respective lengths. When assembled, the respective perforated sectors are aligned to form a perforated, production sector and the respective blank sectors are aligned to form the blank, alternate flowpath. The base pipe is wrapped with wire to prevent solids from flowing through the openings therein. Slurry is pumped into the annulus where it flows circumferently from the blank, alternate flowpath to exit into the well annulus through the openings in the perforated sector of the annulus.
