ABSTRACT:
A well screen device having body member, screen member attached to the body member, cup member attached to the body member for positioning the device in a fluid flow path, and channel member for conducting screened fluid from the screen. The device's cup member extends outwardly or is extensible outwardly from the device sufficiently to contact the interior surface of the flow path in which the device is emplaced to prevent the flow of unscreened fluid beyond the device. The body member can be solid or hollow with plugged ends. Spacer members can be used to mount the cup member to the body member and to provide a portion of the channel member for conducting the screened fluid past the cup member.
