Abstract:
A wellscreen has a gravel pack assembly installed that can communicate slurry from a transport tube to a pack tube. A bypass has erosion resistant surfaces exposed to flow of the conveyed slurry and diverts portion of the conveyed slurry from the fluid bore of the transport tube to a tube opening, from which the pack tube extends. The bypass can be incorporated into the top ring for supporting the filter on the basepipes. A sheath of erosion resistance can be formed on or installed in a channel of the end ring to be covered by a cover.

Claim (Index 18):
A gravel pack assembly for delivering slurry along tubing of a wellscreen, the assembly comprising:\n a ring disposed on the tubing of the wellscreen, the ring having first and second sides opposing one another and defining a chamber therein, the chamber having one or more first tube openings on the first side and having one or more second tube openings on the second side; one or more first tubes for conveying the slurry, each of the one or more first tubes having a first end positioning in fluid communication with one of the one or more first tube openings on the first side of the ring and positioning along the tubing of the wellscreen; one or more second tubes for conveying the slurry, each of the one or more second tubes having a second end positioning in fluid communication with one of the one or more second tube openings on the second side of the ring and positioning along the tubing of the wellscreen; and an erosion-resistant sheath having erosion-resistant surfaces disposed inside the chamber and exposed to the conveyed slurry, the erosion-resistant surfaces communicating the one or more first tube openings with the one or more second tube openings.
