Abstract: An integral well filter and screen and a method for making and using it are described. A first embodiment includes a perforated cylindrical well screen with a filter assembly in its interior. The filter assembly includes a pliable filter material bonded to a filter support. The filter support is a plastic lattice rigid enough to hold the shape of the filter assembly and keep the filter material in contact with the inner surface of the well screen, yet deformable enough that the filter assembly can be formed into a shape consistent with the interior of the well screen. A second embodiment includes a well screen with a filter made of a rigid, porous material placed inside the well screen. Because the filter is rigid, it needs no filter support. Methods of manufacturing each of the embodiments are presented.
