Abstract
A screen assembly (60) comprises a base pipe (62) having perforated and nonperforated sections (66, 68), ribs (70) circumferentially spaced therearound and a filter medium (84) positioned around the ribs (70) having voids (92, 94) therethrough. The screen assembly (60) includes a slurry passageway (98) defined by the nonperforated section (68) of the base pipe (62), two of the ribs (70) and the portion (100) of the filter medium (84) that is circumferentially aligned with the nonperforated section (68). This portion (100) of the filter medium (84) has a filler material (96) disposed within the voids (92, 94) to create a fluid tight seal for a fluid slurry. The fluid slurry is discharged from the screen assembly (60) to a plurality of levels of the interval through exit ports (106) in a plurality of manifolds (102) when the screen assembly (60) is in an operable position.
