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.

Abstract: A downhole tool or plug is used for sealing in tubing. A mandrel of the tool has a first shoulder disposed toward a downhole end of the mandrel. A sealing element for sealing in the tubing is disposed on the mandrel adjacent the first shoulder, a slip is disposed on the mandrel adjacent the sealing element, and a cone is disposed on the mandrel adjacent the slip. In setting the tool, the cone moves toward the first shoulder, wedges the slip against the tubing, and compresses the sealing element between the slip and the first shoulder. Force applied against a seated plug in the mandrel transfers through the mandrel to the cone and slip without passing through the sealing element.
