ABSTRACT:
Systems and methods for gravel packing which provide a mechanism for a gravel slurry to bypass bridges which may form in the well intervals being packed. In one embodiment, a plurality of short, independent bypass flow paths are provided along the length of a well screen. Each of the bypass flow paths comprises a sub-interval of the length of the well screen. The bypass flow paths are preferably staggered to allow the upper ends of the flow paths to be spaced at intervals along the length of the well screen which are shorter than the lengths of the flow paths themselves.
