Abstract: A technique includes completing a well, including installing a tubing string that includes a screen in the well and installing a fiber-based material outside of the screen. The technique further includes using the well as an injection well, including communicating a fluid into the tubing string to cause an injection flow to be communicated in a fluid flow path from an interior of the tubing string, through the screen and into a formation.

Abstract: A gravel pack system and method for zonal isolation includes a swellable element used 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.

Abstract: 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.

Abstract: An apparatus and related methods for removing hazardous trace elements from hydrocarbon reservoir effluent is implemented by placing an adsorbing volume of material designed to adsorb the hazardous trace elements into the vicinity of a producing formation face at a downhole location; and letting the reservoir effluent flow through the volume of adsorbing material.

Abstract: A packing tube isolation assembly, which includes a first conduit, a second conduit, and a sealing member. The first conduit extends substantially parallel to a longitudinal axis of a tube disposable in a wellbore and has an opening defined in the first conduit. The second conduit fluidly connects to an annulus of the wellbore and to the opening of the first conduit, and is disposed at an angle with respect to the first conduit. The sealing member is disposed adjacent the second conduit and is configured to move into and substantially obstruct the second conduit when the second conduit is at least partially packed with a gravel slurry.

Abstract: A transient overbalance condition is created in a wellbore interval such that a pressure of the wellbore interval is greater than a reservoir pressure in surrounding formation. Creating the transient overbalance condition causes a near-wellbore region of the formation to increase in pressure. The pressure in the wellbore interval is reduced at a rate that produces a relative underbalance condition in which the pressure in the wellbore interval is less than the pressure of the near-wellbore region of the formation, but the pressure in the wellbore interval is greater than the reservoir pressure.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A method of gravel packing a wellbore which has at least one aperture therein that provides a fluid flow path between the wellbore and an adjacent subterranean formation. At least a part of the formation adjacent to the open hole has a filter cake coated thereon that comprises a water and oil emulsion. The method of gravel packing comprises injecting into the wellbore a gravel pack composition that comprises gravel and a carrier fluid. The carrier fluid comprises an aqueous liquid having a pH that is outside the range at which the filter cake emulsion is stable. The aqueous liquid is present in an amount effective to invert the water in oil emulsion in the filter cake when the carrier fluid comes into contact with the filter cake. As a result, gravel is deposited at or adjacent to the aperture in the wellbore and some of the filter cake is removed.

Abstract: This invention provides improved apparatus and methods for completing a subterranean zone penetrated by a wellbore utilizing a gravel pack operation. One embodiment of the invention is an apparatus for completing a subterranean zone penetrated by a wellbore comprising a tubular member having a wall and a longitudinal bore. A plurality of apertures extend through the tubular member wall, the apertures define at least one radial arc and create at least one perforated radial aperture zone and at least one non-perforated radial blank zone. A screen member is attached to the exterior of the tubular member that covers the apertures. The placement of the apparatus within the wellbore creates an annular flow region that has a reduced tendency for premature dehydration of slurry during a gravel pack completion operation.
