Abstract: There is provided a running tool for running an apparatus for patching a wall of a conduit to and activating the apparatus in a location in the conduit wherein the apparatus comprises a rolled up or curled up piece of material for patching the wall, wherein the piece of material has a surface comprising an adhesive compound for fastening the piece of mate-rial securely to the wall of the conduit, and wherein the miming tool comprises a heater for providing heat for the apparatus for heating the compound and a forcing device for apply-ing a force to the piece of material for forcing or holding the piece of material against the wall of the conduit, and a running tool for a downhole apparatus for patching a wall of a conduit, wherein the apparatus comprises a plurality of pieces of material for patching the wall of the conduit. There is also provided herein methods of patching a conduit.

Abstract: A device is for forming a barrier in an annulus of a well. The device has an injection tool adapted to introduce a polymeric hardening liquid in through an opening in the annulus, and a pump unit adapted to provide pressure to said liquid so that the liquid is introduced into the opening in the annulus with a controllable pressure. The device has a control unit adapted to control the pump unit so that said liquid is provided into the opening with an initial pressure at a start-up phase of introducing the liquid into the opening and a final pressure at a close-down phase of introducing the liquid into the opening, wherein the final pressure is higher than the initial pressure.

Abstract: A method and apparatus for lining at least one part of a wall of a conduit. In particular embodiments, a piece of material in the form of a sheet may be provided with adhesive thereupon, the sheet being curled or rolled up to allow insertion into the conduit. The curled or rolled up sheet may then be positioned inside the conduit, and once positioned inside the conduit, may at least partially uncurl or unroll to apply the sheet to the wall via the adhesive to obtain a laminate.

Abstract: A sleeve valve device for fluid flow between a hydrocarbon reservoir and a well in the hydrocarbon reservoir comprises a fixed outer sleeve (1) and an inner sleeve (2) which is rotatable in order to bring apertures (3, 4) in the outer sleeve and the inner sleeve into and out of correspondence with each other, for adjustment of the fluid flow through the apertures. The inner sleeve comprises at least one external bulb (5) with a surface (6) which, in an unassembled, unloaded condition of the outer sleeve (1) and the inner sleeve (2), is at a distance (11) from the inner sleeve's centre line (9) which is greater than the outer sleeve's internal radius (r2).

Abstract: The invention relates to a packer (7) to be included in a production tubing (4) in a well bore (1). The packer (7) comprises an expandable bag (11) located on the outside (56) of a packer body (9), the bag (11) having an outwardly facing semi-permeable wall (12) made from fabric. When setting the packer, a liquid curable resin is injected into the bag (11), which causes an expansion of the bag (11). The resin partly penetrates the outwardly facing fabric wall (12) and seals against the well bore wall (10), and after curing forms a packer seal (58). The invention also relates to a setting tool for setting the packer (7) in the well bore (1) and a method for setting a packer (7) in a well bore (1).

Abstract: The invention relates to a method for setting a packer (7) in a well bore (1), wherein a production tubing (4) with a packer (7) is located in the well bore (1). Abrading means (11) of the packer (7) is radially expanded and rotated, for rounding the well bore wall (10), and packing means (9) are radially expanded against the rounded well bore wall (10). The invention also relates to a packer (7) to be included in a production tubing (4) in a well bore (1), comprising radially expandable and rotatable abrading means (11) for rounding the well bore wall (10), and radially expandable packing means (9), for sealing between the packer (7) and the rounded well bore wall (10).
