A wellbore completion includes a plurality of longitudinal gravel pack
sections disposed within a well, the gravel pack sections being capable of
imposing a predetermined substantially radial flow restriction upon fluid
production flowing radially through the gravel pack section. At least one
of the gravel pack sections creates a radial flow restriction that is
different from the radial flow restriction of at least one other gravel
pack section. The gravel pack sections may comprise graded gravel material
having an effective permeability within a predetermined range when placed
in the well.
