Abstract: The present invention relates to a re-connecting device (1) for connecting and sealing against a damaged existing/remaining tubing (5) in a well bore, a casing string (2) or a pipe, the tubing (5) having smaller diameter than the casing string (2), and for repairing of the tubing (5), comprising an outer body (3) and at least one sealing element (18) arranged therein, the outer body (3) is arranged to enable the entrance of, and surrounding, the end part of the tubing (5) in the well bore, casing string (2) or pipe, and a sealing assembly (8) is arranged in the outer body (3), of the re-connecting device (1), for sealing it against the tubing (5).

Abstract: A joint connects casing sections of a casing string for transporting fluids and/or gases. The joint includes a first longitudinal part arranged to be at least partly overlapping a second longitudinal part or a casing section. The first longitudinal part is connected with the second longitudinal part or with the casing sections in a mounted state with the first longitudinal part adapted to move axially relative to the second longitudinal part or the casing sections in an operative state. The joint includes at least one shear member with a predefined shear value and the shear member is adapted to shear when an axial force exceeding the total shear value of the shear member is exerted, allowing a relative axial movement between the first longitudinal part and the second longitudinal part or the casing sections.

Abstract: The present invention relates to a packer device (1) for sealing against an inner surface of a surrounding pipe or casing string (4), preferably for isolating zones or sections in an oil well, comprising a tubing body (3) and at least one sealing element (7a, b), where a cylinder/piston arrangement (2) comprises a cylinder (5) having a closed volume containing a fluid, such as a gas or liquid, arranged to expand when exposed to heat thereby exerting a mechanically pressure on movable elements (12), initially locked in a fixed position by means of at least one fixing element, such as a shear member (6), and where the movable elements (12) are adapted to be released into an operative state at a predetermined axial force, exerted by the closed volume in the cylinder (5), resulting in that the at least one sealing element (7a, b) is pressed radially outwardly in such a way that it seals the packer device (1) against the surrounding pipe-/casing string (4).
