Abstract (en)
[origin: WO2006003112A1] A wellbore screen (1) is provided for controlling inflow of solid particles into a wellbore (2). The wellbore screen comprises a conduit (3) for transporting fluid, an outer layer (4) comprising a filter for reducing inflow of solid particles into the conduit (3), the outer layer extending around the conduit and being radially expandable against the wellbore wall, and swelling means arranged between the conduit and the outer layer. The swelling means (6) is susceptible of swelling upon contact with a selected fluid so as to radially expand the outer layer against the wellbore wall.
