Reducing erosional peak velocity of fluid flow through sand screens

A sand control screen assembly deployable within an open hole section of a wellbore, comprising:

• a base pipe that defines a plurality of flow ports;
• a sand screen arranged about the base pipe;
• a wellbore isolation device deployable within an annulus defined between the sand control screen assembly and an inner wall of the wellbore;
• and
• a peak flux reducing assembly arranged axially adjacent the wellbore isolation device to reduce a peak velocity of fluids traversing the sand screen, wherein the peak flux reducing assembly comprises a flow diverter extending from the wellbore isolation device radially above an end of the sand screen within the annulus, and wherein the flow diverter progressively reduces a volumetric flow area of the annulus in an uphole direction at the end of the sand screen.

• one or more housing flow ports defined in the base pipe radially beneath the housing;
• an impermeable section of the base pipe extending between the one or more housing flow ports and the plurality of flow ports;
• and
• a flow diverter extending from the wellbore isolation device radially above an end of the sand screen within the annulus.
