Abstract
An apparatus and method for gravel packing an interval of a wellbore comprises an outer tubular ( ), which forms a first annulus with the wellbore, and an sand control screen ( ) disposed within the outer tubular ( ) forming a second annulus therebetween. Within the second annulus is an axially extending production pathway ( ) and an axially extending slurry passageway ( ), which is defined between a sheet member ( ) positioned on the sand control screen ( ) and a channel ( ). The outer tubular ( ) has outlets ( ) that are substantially aligned with outlets ( ) of the channel ( ). When a fluid slurry containing gravel is injected through the slurry passageway ( ), the fluid slurry exits through the outlets ( ) leaving gravel in the first annulus, thereby gravel packing the interval.
