Abstract
A well screen for gravel-packing a wellbore interval comprising at least two joints connected by a well tool. Each joint is comprised of a length of screen section which has at least one, axially-extending shunt conduit thereon for carrying gravel slurry to different levels within the interval. The well tool has at least one by-pass tube therein which is adapted to align with and fluidly-connect the shunt conduits on respective joints whereby gravel can flow from one of the shunt conduit, through the by-pass tube, and into and out of the other shunt conduit. A packing means is mounted on the tool for preventing any substantial annular, axial flow past the tool when the tool is an operable position within the wellbore.
