Abstract

A screen assembly (38) and method for progressively treating an interval (48) of a wellbore (32) is disclosed. The screen assembly (38) comprises a sand control screen (40) that is positioned within the wellbore (32) and a plurality of diverter members (42) that are positioned along the sand control screen (40). During a treatment process when a treatment fluid is pumped into the interior of the sand control screen (40), the diverter members (42) progressively allow the treatment fluid to exit from the interior of the sand control screen (40) to the exterior of the sand control screen (40) from a first end (46) of the interval (48) to a second end (44) of the interval (48) to progressively treat the interval (48) of the wellbore (32).
