Abstract:
1. A method of manufacturing a screen assembly capable of being disposed in a bore, the method comprising: positioning a casting member exterior to a base pipe; positioning a support material between the casting member and the base pipe; positioning a swellable material between the support material and the base pipe, the swellable material being configured to expand in response to an activating fluid and expand more than the support material; processing the swellable material to form a groove in which the casting member and the support material are disposed; removing the casting member from the groove; positioning a tube having a plurality of perforations in the groove, the tube being adapted to direct fluid to an outer housing prior to directing the fluid to an inner diameter of the base pipe; and thereby providing a screen assembly having the support material situated intermediate the swellable material and the tube for preventing the swellable material from plugging the plurality of perforations in the tube upon expansion of the swellable material.
