Abstract
A well screen and method for gravel packing a wellbore interval wherein a low-viscosity slurry can be used to distribute the gravel. A well screen having a plurality of spaced intermediate manifolds is lowered into the interval and slurry is pumped down the well and into the first manifold. 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.
