A shunt system for a wellbore includes a first set of tubes defining a first plurality of fluid paths and a second set of tubes defining a second plurality of fluid paths. The shunt system also includes a mixing chamber positioned between the first set of tubes and the second set of tubes to allow slurry from the first plurality of fluid paths to mix together prior to outputting the slurry to the second set of tubes. Further, the shunt system is positionable external to one or more sand screens.

Shunt tube system for gravel packing operations

A single trip multi-zone completion system includes a plurality of completion sections operatively coupled together and extendable within a wellbore. Each completion section includes a base pipe providing an interior and defining one or more perforations at a single axial location to provide fluid communication between the interior and an annulus defined between the completion section and a wellbore wall. One or more sand screens are radially offset from the base pipe such that a flow annulus is defined therebetween, and a production sleeve is movably arranged within the interior of the base pipe between a closed position, where the production sleeve occludes the one or more perforations, and an open position, where the one or more perforations are exposed. A shunt system is positioned about the base pipe to receive and redirect a gravel slurry flowing in the annulus, and thereby provide an alternate flow path for the gravel slurry.

A downhole sand control completion system includes a completion string extendable within a wellbore and including one or more sand control screen assemblies arranged about a base pipe, each sand control screen assembly including one or more sand screens positioned about the base pipe. A shunt system is positioned about an exterior of the base pipe to receive and redirect a gravel slurry flowing in an annulus defined between the completion string and a wellbore wall. A return tube is positioned about the exterior of the base pipe and extends longitudinally along a portion of the completion string. The return tube defines a plurality of openings to receive a portion of a fluid in the annulus into the return tube to be conveyed into an interior of the base pipe via the return tube.

A wellbore completion system includes a tubular positioned in the wellbore such that an annulus is created between the tubular and a portion of the wellbore. The system further includes a gravel pack packer, a first packer positioned downhole of the gravel pack packer, and a second packer positioned downhole of the first packer. The gravel pack packer and the first packer define a first zone in the annulus, and the first and second packers define a second zone in the annulus. A wash pipe is positioned within the tubular and is positionable in a first position to allow fluid communication between a first port and the first packer and a second port and the second packer. The wash pipe is positionable in a second position to allow fluid communication between the first port and the first zone and the second port and the second zone.

Completion system for gravel packing with zonal isolation

A method of controlling a blowout comprises: releasing at least a first tubing string into a portion of a well system, wherein the step of releasing comprises activating a release table; and causing or allowing a blowout preventer to close. The methods further comprise: compressing at least a portion of a second tubing string and a third tubing string together, wherein the step of compressing comprises activating a crimping device; cutting through the wall of at least a third tubing string, wherein the step of cutting comprises activating a cutting device, and wherein the step of cutting is performed after the step of compressing; and releasing at least the second tubing string and the third tubing string into a portion of a well system, wherein the step of releasing comprises activating a release table.

Methods of releasing at least one tubing string below a blow-out preventer

A method of completing at least a portion of an open-hole wellbore comprises: positioning a sand control assembly in the portion of the open-hole wellbore, wherein the sand control assembly comprises a screen; positioning at least one conduit adjacent to the sand control assembly; positioning a sheath in the portion of the open-hole wellbore, wherein the sheath is a non-porous tubular, and wherein the sheath is positioned such that a sheath annulus exists between the inside wall of the sheath and the outside wall of at least a portion of both, the sand control assembly and the at least one conduit; and introducing a treatment fluid into the portion of the open-hole wellbore.
