Title:
IMPROVED WELL SCREEN WITH INTERNAL SHUNT TUBES EXIT NOZZLES AND CONNECTORS WITH MANIFOLD
Document Type and Number:
WIPO Patent Application WO2004094769
Kind Code:
A3
Abstract:
A well screen for use in fracturing and/or gravel packing completions that produces a good distribution of gravel over the entire completion interval. The screen is comprised of a base pipe and an outer surface (e.g. wire wrap). A plurality of flow paths (e.g. shunt tubes) are positioned in the annulus formed by the base pipe and the outer surface of the screen, and connected to corresponding exit nozzle chambers positioned at different levels on the screen to supply gravel slurry throughout the well annulus. Thereby providing the necessary alternate flowpaths for the slurry without significantly increasing the overall effective outside diameter of the screen. The screen includes one or more joints each connected together via a special connector that incorporates a manifold area. Thereby making for simpler installation and faster make up of the joints, and eliminating the need for any special tools to run the screens in the well.
