Summary:A wellbore screen is provided for controlling inflow of solid particles into a wellbore. The wellbore screen comprises a conduit for transport of fluid, the conduit being provided with a filter for reducing inflow of solid particles into the conduit and swelling means arranged between the filter and the wellbore wall. The swelling means defines a plurality of compartments between the filter and the wellbore wall and is susceptible of swelling against the wellbore wall upon contact with a selected fluid so as to substantially prevent flow of fluid along the outside of the swelling means from one of said compartments into another of said compartments.
