Abstract

An apparatus and method for progressively treating an interval of a wellbore (32) is disclosed. The apparatus comprises a sand control screen (138) that is eccentrically positioned within the wellbore (32) and a fluid delivery tubular (140) that is disposed within the wellbore (32) adjacent to the sand control screen (138). During a treatment process when a treatment fluid is pumped into the fluid delivery tubular (140), the fluid delivery tubular (140) progressively allows the treatment fluid to exit from the interior of the fluid delivery tubular (140) to the exterior of the fluid delivery tubular (140) 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).
