An expandable well screen provides increased collapse, torsional and tensile strength. In a described embodiment, an expandable well screen includes a generally tubular base pipe and an external filtering media. The well screen is configured to have sufficient torsional and tensile strength for conveyance and positioning in a wellbore, while also having sufficient strength to prevent collapse when the screen is radially expanded.

Expandable well screen

Disclosed are apparatus and methods for movably securing a radially expandable sand-control screen jacket assembly to a base pipe. The screen jacket assembly is connected to the base pipe with a longitudinally moveable, sand-controlling joint. In use, the joint slides maintain a sand-controlling seal after radial expansion of the sand-control screen jacket assembly.
