Abstract

An expandable well screen has a desirable thin-wall construction together with a simplified fabrication method. In fabricating the screen, a flexible sheet of metal mesh filter media is diffusion bonded to an inner side of a perforated metal sheet which is then deformed to a tubular shape to form a filter structure having an outer perforated tubular shroud interiorly lined with the filter media. The tubular filter structure is telescoped onto a perforated base pipe and has its opposite ends sealingly secured thereto to complete the expandable well screen.
