Abstract
A method and apparatus including a screen assembly that includes a screen having a plurality of openings and a sacrificial shroud disposed over a portion of the openings and disposed to erode under flow of formation fluid through the screen. The shroud is configured to erode more quickly than the screen over which it is disposed, thereby altering the erosion zone of the screen over time and prolonging the life of the screen.
