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.

Abstract: A gravel pack assembly for a borehole has first and second joints and a foil. The basepipes of the joints connect end-to-end, and both of the basepipes having filters for filtering fluid passage from a borehole into bores of the basepipes. Transport tubes are disposed along the first and second joint, and a jumper tube expands across the connected ends of the basepipes and connects the transport tubes together. The foil encloses an area across the connected ends. The foil has an external surface defining an annulus thereabout with the borehole. The foil has end rings abutting the filters of the joints. At least a section of the foil leaks fluid from the borehole to the area enclosed by the foil, and at least a filter portion of the assembly filters the leaked fluid from the area to at least one of the first and second bores.

Abstract: A well screen assembly has a base pipe and one or more screen sections attached to the outer surface of the base pipe. The assembly also has one or more shunt tubes attached to the base pipe via top and bottom rings. The shunt tubes can be attached to the screen sections via B-rings and may be transport tubes or packing tubes. Connections are used for securing a jumper tube to adjoining shunt tubes of adjoining screen sections of the wellscreen assembly, which may be used in open or cased holes. At a well site, the joints of the wellscreens have timed threads so that the various shunt tubes can be aligned with one another along the assembly as the joints are made up. The connections of the present disclosure allow operators to install a jumper tubes between shunt tubes at the joint without needing to tighten fasteners or assembly components.

Abstract: A completion joint 100 has two sand control jackets 120A-B connected on each end of an intermediately-mounted inflow control device 130. Both jackets 120A-B communicate with a housing chamber 155 through dedicated open end-rings 140A-B. The basepipe's flow openings 118 are isolated from this housing chamber 155 by a sleeve 160 fitted with flow ports 170. The housing 150 is removable to allow access to the flow ports 170 for pinning to configure the ports 170 open or closed for a given implementation.

Abstract: A sand control device is used for restricting the flow of particles from a subsurface formation into a tubular body within a wellbore during production operations. The sand control device is divided into compartments along its length that provide redundancy for particle filtration. Each compartment first comprises a base pipe. The base pipe defines an elongated tubular body having a permeable section and an impermeable section within each compartment. Each compartment also comprises a first filtering conduit and a second filtering conduit. The filtering conduits comprise filtering media and generally circumscribe the base pipe. The filtering conduits are arranged so that the first filtering conduit is adjacent to the non-permeable section of the base pipe, while the second filtering conduit is adjacent to the permeable section of the base pipe.

Abstract: A gravel pack apparatus for a wellbore has a shunt tube disposed along the apparatus near a wellscreen. The shunt tube is typically composed of stainless steel and has an internal passage for conducting slurry. Along its length, the tube has flow ports for passing the conducted slurry into the wellbore. The exit ports can use erosion inserts composed of erodible material, barrier inserts having breakable barriers, flow nozzles with external sheaths or caps, erosion-resistant bushings disposed on the flow nozzles, etc. The tube can also include a tube body having the exit ports and flow nozzles integrally formed thereon. The tube body can couple end-to-end with sections of shunt tube.

Abstract: A completion joint 100 has a sand control jacket 120 and an inflow control device 130. The jacket 120 communicates screened fluid with a housing of the inflow control device 130. The basepipe's flow openings 118 are isolated in the housing from the screened fluid by flow devices 170. The flow devices 170 are externally accessible on the device's housing to selectively configure the flow devices 170 open or closed.
