Abstract
A recirculating gravel pack system includes a tubular member having an outer surface, an inner surface defining a flow path, a first opening extending from the inner surface through the outer surface and a second opening, spaced from the first opening extending from the inner surface through the outer surface. A screen is positioned about the tubular member spaced from the outer surface defining a passage that is selectively fluidically connected to the second opening. A return tube extends between the screen and the outer surface running axially along the tubular member. The return tube includes a first end defining an inlet arranged in the passage and a second end defining an outlet positioned in a low-pressure zone outside the passage downhole from the first opening.
