Abstract
A method of providing a downhole seal, such as a packer (12), in a drilled bore between inner tubing (11) and outer tubing (16) comprises: providing an intermediate tubing section (18) defining a seal arrangement for engaging with the inner tubing; and radially plastically deforming the intermediate tubing section downhole to form an annular extension (40a, 40b). The extension creates a sealing contact with the outer tubing (16).
