Abstract: Employing a sleeve that spans the connection and a ring seal enhances the sealing integrity of expanded connections. The expansion of the connection brings the connection to the sleeve and engages the seal with the sleeve. The seal can be on the connection or the sleeve and the assemblies can be provided inside or outside the connection or in both places. A recess can be provided in either case so that after expansion the sleeve is flush to the interior or exterior wall.

Abstract: A screen to be expanded when placed downhole is disclosed. The screen is delivered to the location with a cover that blocks access to the screen from well fluids. Circulation or reverse circulation can be undertaken with no appreciable flow through the screen due to placement of the cover. In one embodiment the cover has slits that open to be diamond shapes upon expansion of the underlying screen. In another embodiment, the openings are created by shapes that have a weakened edge that, as a result of expansion break off to create available openings for flow.
