Abstract
A system and method is provided for filtering in a wellbore during various well related operations while limiting the potential for plugging. A well screen is used for filtering particulates from a fluid at a wellbore location. To remove accumulated material and avoid plugging, the well screen may be flexed via pressure differentials created across the well screen. The flexing of the well screen breaks free the accumulated materials, thereby avoiding premature job failure.
