Packer, setting tool for a packer and method for setting a packer

A packer (7) according to any of the preceding claims, characterised by a deformable packer mesh (16) located on the outside of the bag (11), whereby the expansion of the bag (11) deforms the mesh (16) and forces the mesh (16) against the well bore wall (10), whereupon the resin which penetrates the outwardly facing fabric wall (12) fills openings (17) in the mesh (16).

A packer (7) according to any of the preceding claims, characterised by that the bag (11) is essentially annular, and extends around the packer body (9).

A packer (7) according to any of the preceding claims, characterised by that the expandability of the bag (11) is achieved by the bag (11) being foldable and can assume a folded position in which the outwardly facing fabric wall (12) is proximal to the packer body (9) and an unfolded position in which the outwardly facing fabric wall (12) is proximal to the well bore wall (10).

A packer (7) according to any of the preceding claims, characterised by that the permeability of the fabric is dependent upon the differential pressure across the fabric.

A packer (7) according to any of the preceding claims, characterised by that a static mixer (18) for mixing a two-component resin is located in the injection conduit(s) (13).

A method for setting a packer (7) comprising a body (9) which forms part of a production tubing (4) which is located in a well bore (1), characterised by

• injecting a liquid curable resin having an injection pressure in an expandable bag (11) located between the packer body (9) and a wall (10) of the well bore (1), the bag (11) having an outwardly facing semi-permeable wall (12) made from fabric, the resin thereby fills and expands the bag (12) and partly penetrates the fabric and seals against the well bore wall (10),
• essentially maintaining the injection pressure during curing of the resin, whereupon the resin after curing forms a packer seal (58).
