Abstract
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.
