    摘要: Apparatus and methods for gravel packing. The method is particularly useful for deploying a sand screen assembly having shunt tubes. The apparatus can include two or more tubulars disposed about at least one expandable member. The tubulars are longitudinally aligned with one another and bundled together in a run-in position, and the bundled tubulars radially expand when the expandable member is activated.

    摘要: A gravel pack system and method for zonal isolation is disclosed by using a swellable element in conjunction with a primary isolation device, such as a cup packer. The zones may be isolated by both the isolation device and the swellable element. Shunt tubes may be used to convey a gravel slurry to each zone. At least one upper shunt tube extends through the isolation device to provide the slurry to the zone therebelow. Once the gravel packing is completed, the swellable member may be activated to provide and supplement a hydraulic seal between adjacent zones.

    摘要: A completion string for use in a wellbore includes a main conduit, such as a production tubing, and one or more alternate path conduits, such as shunt tubes, that extend generally in parallel with the main conduit. A flow control device is positioned in each alternate path conduit to control flow through the alternate path conduit. The one or more alternate path conduits may be adapted to carry gravel slurry to perform gravel packing operations. The one or more flow control devices in the one or more alternate path conduits may be actuated to the open position to allow communication of the gravel slurry to multiple zones in the wellbore. Once the gravel packing operation is completed, the one or more flow control devices may be actuated to the closed position to block fluid flow communication between multiple zones through the alternate path conduits during operation of the well. Other types of fluids may be communicated through the one or more alternate path conduits, such as fracturing fluids.

    摘要: A well screen having an internal, blank alternate flowpath for delivering fracturing fluid/gravel slurry to different levels within a well annulus. The well screen includes an outer pipe which is positioned over a base pipe thereby forming an annulus therebetween. The circumference of each pipe has a perforated sector and a blank sector, both of which extend along their respective lengths. When assembled, the respective perforated sectors are aligned to form a perforated, production sector and the respective blank sectors are aligned to form the blank, alternate flowpath. The base pipe is wrapped with wire to prevent solids from flowing through the openings therein. Slurry is pumped into the annulus where it flows circumferently from the blank, alternate flowpath to exit into the well annulus through the openings in the perforated sector of the annulus.

    摘要: A gravel pack apparatus for use in a wellbore includes a screen assembly to filter particulates, at least one shunt conduit to carry gravel slurry, and a swellable element around a portion of the at least one shunt conduit. The swellable element swells in response to an input stimulus and expands radially outwardly to seal against the wellbore.

    摘要: Method and apparatus for gravel packing an open-hole wellbore are disclosed. The apparatus includes a sandscreen disposed in the wellbore thereby creating an annulus between the wellbore and the sandscreen for receiving a gravel slurry. The apparatus further comprises a tubular member or wash pipe which is concentrically disposed in the sandscreen for receiving carrier fluid which passes through the sandscreen and for returning the carrier fluid to the earth's surface. At least one diverter valve is installed in the tubular member for permitting flow of the carrier fluid into the tubular member.

    摘要: A technique is provided to selectively control flow along shunt tubes, such as those used in gravel pack operations. The technique utilizes a swellable material valve that comprises a swellable material deployed along the shunt tube flow path. When flow through a specific shunt tube is no longer desired, the swellable material valve can be exposed to a substance that induces swelling of the swellable material. The expanded or swollen material blocks further flow along the shunt tube.
