 A deformable well screen for preventing migration of solid particles into a hydrocarbon production well is disclosed, the screen including at least one substantially tubular filter layer of which the sieve opening size remains fairly constant during or after expansion and/or other formation of the screen. Optionally the screen also includes a series of circumferentially scaled filter segments that are arranged around an expandable slotted tube, an expandable slotted tube of which the slots are filled with resin coated granules, an expandable slotted tube with micro-slots, an assembly of woven metal wire screens that are sintered together and/or a synthetic geotextile fabric.
