    摘要: A downhole tool including an insertion member arranged to insert into and form an annular seal with a receiving member using an annular seal assembly. The seal assembly includes a compliant metal spring and a separate metal cover overlapping at least a portion of an outside of the spring, wherein the cover and spring extend radially outward from the downhole tool so as to be compressed when the insertion member is inserted within the receiving member to form an annular metal-to-metal seal between the insertion member and the receiving member. A method of coupling the downhole tool and the receiving member in a well includes inserting the insertion member of the downhole tool into the receiving member and energizing and forming an annular metal-to-metal seal by compressing the seal assembly between the insertion member and the receiving member when inserting the insertion member into the receiving member.

    摘要: An annular barrier for providing zonal includes a tubular metal part, and an expandable metal sleeve surrounding the tubular metal part. The expandable metal sleeve has a first end part, a second end part and an outer face, and at least one of the end parts includes at least one circumferential groove facing the outer part face, wherein the tubular metal part bulges radially outwards in relation to the axial extension, forming at least one circumferential projection engaging the groove, thus providing a connection of the expandable metal sleeve to the tubular metal part.

    摘要: Swellable packer assemblies, downhole packer systems, and methods to seal a wellbore are presented. A swellable packer assembly includes a mandrel and a sealing material disposed about a portion of the mandrel, where the sealing material is formed from a material that radially expands from the mandrel in response to fluid exposure. The swellable packer assembly also includes a cover that is initially disposed about a portion of an outer surface of the sealing material, where the cover prevents the sealing material from being exposed to fluid while the cover is positioned about the portion of the outer surface of the sealing material, and a pressure-actuated piston configured to shift from a first position about the mandrel to a second position about the mandrel, where the sealing material is exposed to fluid after the pressure-actuated piston shifts from the first position towards the second position.

    摘要: A technique facilitates patching of a tubing (42), e.g. casing (36), in a downhole environment (32). The technique employs a patching system comprising a plurality of expansion rings (48). The expansion rings (48) are moved downhole to a patch zone (38) along the tubing (34). Once in a desired position at the patch zone, the expansion rings (48) are expanded into engagement with an inner surface of the tubing. For example, the expansion rings may comprise seal elements (52) and/or anchor elements which are expanded into engagement with the inside surface. The patching system further comprises a patch (68) which may have a tubular shape. The patch is radially expanded in a manner which maintains a sealing engagement with the plurality of expansion rings (48) to create a sealed patch across a desired region in the patch zone.

    摘要: An example method of forming a well includes identifying a lost circulation zone in a wellbore, where the lost circulation zone includes a fracture in a formation adjacent to the wellbore; arranging an inflatable in a vicinity of the lost circulation zone; forcing slurry into the inflatable to cause at least part of the inflatable containing the slurry to expand into the fracture; allowing the slurry to set for a period of time to produce a solid; and drilling through the solid in the inflatable in the wellbore, leaving the solid in the fracture.

    摘要: A method of managing a fluid flow within a conduit includes determining a presence of a flow blockage within the conduit, the conduit being equipped with an expandable device, controlling an electric actuator to flow a current to the expandable device to expand the expandable device radially, compacting the flow blockage radially along a length of the expandable device to create a channel adjacent the flow blockage, controlling the electric actuator to terminate a flow of the current to the expandable device to collapse the expandable device radially, and exposing the channel to open the conduit to fluid flow.

    摘要: A wellbore isolation device is provided which includes a tubular body having an external surface and an inner bore formed longitudinally through the tubular body. The tubular body has an expanding section transitionable from an initial configuration to an expanded configuration. One or more fins project radially from the external surface of the expanding section. The fins are anchorable into surrounding surfaces when the expanding section transitions to the expanded configuration. A plugging element is positioned, after the expanding section is in the expanded configuration, to restrict fluid communication through the inner bore.

    摘要: An inflatable down hole bag includes an inflatable body for holding an inflation fluid and a container for holding one or more substances. The container is disposed inside of the inflatable body and includes a closure for keeping the one or more substances in the container when the closure is in an inoperative state. The closure also releases the one or more substances from the container when the closure is in an operative state. Release of a substance causes an inflation fluid producing reaction within the inflatable body, thereby inflating the inflatable body. The container includes at least two separated chambers. Each chamber holds a respective one of the substances. The closure includes a stopper for closing a respective opening to one of the chambers. The closure further includes an actuator for removing each stopper from the respective opening so as to release each substance from each respective chamber.
