An apparatus and method for gravel packing an interval of a wellbore is disclosed. The apparatus comprises an outer tubular ( ) forming a first annulus with the wellbore and an inner tubular ( ) disposed within the outer tubular ( ) forming a second annulus therebetween. The second annulus includes an axially extending slurry passageway ( ) and an axially extending production pathway ( ). The portion of the outer tubular ( ) adjacent the slurry passageway ( ) has an outlet ( ). The portion of both the outer and inner tubulars ( ) adjacent the production pathway ( ) has a plurality of openings ( ). The slurry passageway ( ) is in fluid isolation from the production pathway ( ) such that when a fluid slurry containing gravel is injected through the slurry passageway ( ), the fluid slurry exits through the outlet ( ) leaving gravel in the first annulus, thereby gravel packing the interval.
