An apparatus (38) and method for progressively gravel packing an interval of a wellbore (32) is disclosed. The apparatus (38) comprises a sand control screen (52) that is positioned within the wellbore (32) and a tubular member (42) that is disposed within the wellbore (32) forming a first annulus (56) with the sand control screen (52) and a second annulus (58) with the wellbore (32). The tubular member (42) initially prevents fluid communication between the first annulus (56) and the second annulus (58). Once the gravel packing operation begins, however, the tubular member (42) selectively allows fluid communication from the first annulus (56) to the second annulus (58) by progressively establishing fluid communication between the first annulus (56) and the second annulus (58) from a first end of the interval (48) to a second end of the interval (48).

Each intermediate manifold has an upper and a lower perforated shunt tube in fluid communication therewith which, in turn, distribute slurry in both an upward and downward direction substantially simultaneously. The slurry exits the respective tubes into spaced zones within the completion interval. By overlapping the exit openings of respective lower and upper shunt tubes of adjacent manifolds, slurry will be delivered to across the entire completion interval.
