A method includes wrapping a packer bag around a deployment tool, providing at least one canister in fluid communication with the packer bag, sending the packer bag around the downhole tool to a downhole location in a well, and injecting a polymer filler material from the at least one canister into the packer bag until the packer bag expands to seal the downhole location.

The present invention relates to an annular barrier for providing zonal isolation in an annulus downhole between a well tubular metal structure and another well tubular metal structure or a wall of a borehole, comprising a tubular metal part configured to be mounted as part of the well tubular metal structure, the tubular metal part having an outer face, an opening and an axial extension along the well tubular metal structure, an expandable metal sleeve surrounding the tubular metal part, the expandable metal sleeve having a circumferential groove, a first end and a second end, each end of the expandable metal sleeve being connected with the outer face of the tubular metal part, and a sealing unit arranged in the circumferential groove, the annular sealing unit comprising an annular sealing element and a back-up sealing element abutting and supporting the annular sealing element, wherein the annular sealing element in a cross-section along the axial extension has a first width, a second width and a third width; the second width is larger than the first width and the third width and is arranged between the first width and the third width; the back-up sealing element has a first contact area, and the annular sealing element has a second contact area, where the first contact area has a shape that mates with the second contact area. The invention also relates to a downhole completion system comprising an annular barrier and a well tubular metal structure.

A drill pipe string conveyed retrievable plug system has a central through bore. The plug system includes a drill pipe string; a control section; a running tool with a connector at a lower end of a drill pipe string with the control section, and a top connector on a mechanical plug section with a bridge plug. The mechanical plug section includes a mandrel with the through bore, a ball valve arranged for closing the through bore, and a packer sleeve on the mandrel with slips and a packer element. The control section includes an electric supply, an electric control unit, and sensors connected to the electric control unit. The mechanical plug section includes a motor controlled by the electrical control unit. The motor is arranged to turn a selector ring to a selected first rotational position so as for allowing a piston sleeve to slide to an axial first stop position in order for opening to fluid channels through the mandrel from the through bore to the packer sleeve. The pressure in the through bore can be set to the pressure of the packer sleeve in a surrounding casing.

A straddle packer has a floating auto-J sleeve that automatically shifts the straddle packer from a run-in condition to a stay-set condition after pumping of high-pressure fluid into the straddle packer in excess of a predetermined pump rate is terminated. In the stay set condition, packer elements of the straddle packer remain in sealing contact with a well casing or well bore into which the straddle packer has been run.

A sealing assembly is disclosed, the sealing assembly comprising a plurality of components including an upper sealing element and a lower sealing element, the sealing assembly configured to encircle a tubular string positioned within a casing of a wellbore. The sealing assembly is configured to be actuatable to extend sealing elements between the tubular string and an inner surface of the casing to form a fluid seal between the tubular element and the inner surface of the casing.

A plug assembly includes an expandable assembly, a locking ring and a cup. The expandable assembly is adapted to be deformed radially over the locking ring and the cup. The locking ring has a stopping inner surface. The plug assembly is used with one or more untethered objects, the untethered objects having an outer surface adapted to couple with the cup, and the cup having an outer surface adapted to couple with the stopping inner surface of the locking ring. The combination of cup and untethered objects is also adapted to contact an inner surface of the plug assembly and, using well fluid pressure, to apply forces to the plug assembly. The forces cause the longitudinal movement of the cup and untethered objects while contacting the inner surface of the plug assembly until the cup contacts the stopping inner surface of the locking ring.

A workstring apparatus for creating an annular seal in a wellbore is described. Workstring comprises at least one packer apparatus comprising a body portion and an elastomeric packer element which is deformable into an outwardly deployed condition to deform wellbore casing. A fluid accumulator is provided to hold fluid to actuate at least one hydraulic cylinder of the packer apparatus. An electrically powered pump is operable to pump fluid from accumulator into the hydraulic cylinders of packer apparatus to deform the elastomeric packer element outwardly. A wireline connects the workstring to the surface and provides electrical power to the workstring. Wireline may be an electrical feed such as a composite rod or e-coil.

A gravel pack system includes a liner assembly and a deployment assembly. The liner assembly includes a sand control screen. The deployment assembly facilitates rotation of the liner assembly and circulation through the liner assembly while running the liner assembly into a wellbore using a work string. The deployment assembly includes a crossover tool that is operated to facilitate gravel packing without manipulation of the work string. The deployment assembly also includes a setting tool for setting a packer and/or a sand barrier at the top of the liner assembly.

A plug assembly, dedicated for ball-in-place operation, includes an expandable assembly, a locking ring, a cup and studs, to be deployed using a retrievable setting tool. The expandable assembly is adapted to be deformed radially over the locking ring and the cup, while the locking ring is retained longitudinally relative to a mandrel of the retrievable setting tool, thanks to the studs positioned within the cup. The locking ring has a stopping inner surface. The combination of the cup and an untethered object is adapted to contact an inner surface of the plug assembly and, using well fluid pressure, to apply forces to the plug assembly. The forces cause the longitudinal movement of the cup and untethered objects while contacting the inner surface of the plug assembly until the cup contacts the stopping inner surface of the locking ring.

A stage cementing tool has a mandrel defining a central flow passage and a plurality of fully open cement flow ports. A packer disposed about the mandrel is movable from an unset to a set position. An opening sleeve is movable in the mandrel from a closed position to an open position in which the flow ports are exposed to allow flow therethrough. The opening sleeve is operable to move the setting sleeve to set the packer against the wellbore as it moves in the mandrel from the closed to the open position.
