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 20):
The assembly of  claim 18 , wherein the erosion-resistant sheath comprises one of:\n a coating of erosion resistant material disposed on an inside surface of the chamber; a hard surfacing of erosion resistance disposed on the inside surface of the chamber; a plurality of plates of erosion-resistant material affixed on the inside surface of the chamber; one or more inserts disposed in the chamber, the one or more inserts defining at least one fluid passage therethrough communicating the one or more first tube openings with the one or more second tube openings, wherein the one or more inserts are composed of an erosion resistant material; and one or more inserts disposed in the chamber, the one or more inserts defining at least one fluid passage therethrough communicating the one or more first tube openings with the one or more second tube openings, wherein one or more inserts comprise a coating of erosion resistant material disposed on an inside surface of the at least one fluid passage.
