| 1. A seal element comprising:
a substantially blank base pipe having a fluid exit passage solely at a downhole end of the pipe, the end being at an end
of the element;
a screen disposed radially of the base pipe such that a fluidic component of a solid laden fluid introducible to the seal
element is drainable radially to a surface of the base pipe and moveable therealong until draining through the fluid exit
passage; and
an expandable material disposed radially outwardly of and substantially coaxially aligned with the base pipe and the screen
such that a radii orthogonal to a common axis of each of the expandable material, the screen and the base pipe intersects
each of the expandable material, the screen and the base pipe.
