Abstract
A gravel pack assembly has a longitudinal body that disposes in a borehole. A wellscreen and other components can connect to the body to complete the assembly. One or more packoff seals or bushings disposed in the body's inner passage can engage a smooth external surface of a crossover tool when disposed therein to prevent passage of sand and fluids between the tool and the assembly's inner passage. The packoff seals or bushings can be fixed or activated by movement to engage the smooth external surface of the crossover tool.
