Abstract

Assemblies and methods pack a borehole annulus with gravel carried by a carrier fluid of a slurry. A manifold is disposed on tubing (e.g., basepipe). A number of first permeable structures in fluid communication with the manifold are disposed adjacent an impermeable (blank) section of the tubing. These first structures filter the slurry in the borehole annulus and pass the carrier fluid filtered into the manifold. A number of second permeable structures in fluid communication with the manifold are disposed adjacent a permeable (screen) section of the tubing. These second structures pass the carrier fluid from the manifold to the borehole annulus adjacent the screen section. In this way, the slurry in the blank section can be dehydrated for gravel packing by leaking of the carrier fluid to the screen section. The manifold and structures can also be beneficial in increasing the producible area of the tubing for production.
