Abstract
Compliant wellbores screens may be arranged to radially expand in a wellbore. The screens include an outer shroud layer including a perforation pattern thereon arranged for limiting the degree to which the screens are expand. The perforation patterns may permit the screens to be expanded to a predetermined limit by imparting a stable or relatively low expansion force. Once the predetermined limit is reached, the outer shrouds may require a sharp increase in the expansion force for further expansion. The sharp increase will prevent over-expansion of the screens, particularly where precise control over an expansion force imparted to expand the screens proves difficult. The perforation pattern may include arc-shaped perforations formed in sheet metal, spaces between braided metal strands, or many other arrangements.
